How Much Oil Does A Lawn Mower Need

What how much engine oil does my engine need?

Before you can change the oil in your small engine Briggs Stratton lawn mowers, it is important to understand what type and how much oil is required. Below we provide an answer to this frequently asked question and explain the two most important steps for determining the type and amount of oil for a lawn mower engine.

How to determine the type of oil for a lawn mower or small engine

We recommend using certified Briggs oils Stratton for best engine performance. Other high quality detergent oils can be used if they are SF, SG, SH, SJ or higher. DO NOT use special additives.

The ambient temperature determines the appropriate viscosity of the engine oil. Use the table to select the best viscosity for your intended ambient temperature range. 5W30 synthetic oil is well suited for most engines in outdoor power equipment. Vanguard 15W50 synthetic oil provides the most effective protection for equipment operating at high temperatures.

Using SAE 30 oil at temperatures below 40 ° F (4 ° C) will result in difficult engine starting.

Using 10W30 above 80 ° F (27 ° C) may result in higher oil consumption. Check the oil level often.

The Society of Automotive Engineers has developed a classification for engine oils that indicates the viscosity (density) and temperature at which an engine oil can be used. It is called SAE, it is printed on every bottle of oil and also indicates whether the oil is synthetic.

Above is a graph showing the SAE oil type and the temperature at which it performs best. The easiest way to find the best oil for your lawnmower is to combine the information from your product operator’s manual with the oil type descriptions below.

Oil Finder. Small engine oil recommendations:

Use SAE 30 at 40 ° F and above (5 ° C and above).
Use SAE 10W-30 in a temperature range of 0 to 100 ° F (18 to 38 ° C). This grade of oil improves cold weather starting, but may increase oil consumption at 80 ° F (27 ° C) or higher.
SAE 5W-30 synthetic oil is optimal for very low temperatures from 20 to 120 ° F (30 to 40 ° C). It provides the best protection at all temperatures and also improves starting with less oil consumption.
Use SAE 5W-30 at very low temperatures of 40 ° F and below (5 ° C and below).
For continuous use, commercial lawn mowing or pressure washing, use Vanguard 15W-50 oil (20 ° F to 130 ° F).

Things to consider when choosing a lawn mower:

Use a quality detergent oil classified “For Service SF, SG, SH, SJ” or higher quality.
DO NOT use special additives.
Synthetic oils are suitable for all temperatures. The use of synthetic oils does not change the required oil change intervals.

Can synthetic lawn mower oil be used? Yes!

We recently changed our recommendation for engine oil: you can now use 5W30 or 10W30 synthetic oil regardless of temperature. We recommend using Briggs synthetic oil Stratton. The use of this high quality detergent oil ensures that the Briggs warranty requirements are met Stratton when using the correct oil.

The engine break-in procedure with the introduction of synthetic oil remains unchanged. Keep in mind that the use of synthetic oil does not prevent you from performing regular maintenance on the mower (i.e. checking the oil, changing it, etc.).

Requirements

High-quality oil that can be poured into a gasoline trimmer must meet a number of requirements and standards in order to ensure reliable operation of the device and its performance. The oil should:

Provide increased wear resistance for various elements (in particular, the gearbox is especially susceptible to this)
Provide the lowest possible smoke and exhaust emissions;
DO NOT allow premature ignition;
Mix well with gasoline when exposed to low temperatures;
Have good viscosity and flow characteristics in various temperature ranges;
Be as safe as possible in terms of environmental impact.

As mentioned, two-stroke engine oil will differ from four-stroke engine oil. It has higher power, which is why fuel for it is obtained by mixing a certain amount of gasoline and oil. The ratio will be different for each lawn mower. You can find out its meaning in the instructions for the device. These proportions must be observed with maximum accuracy. When adding additives, take into account the type of motor.

If mineral oils are used, the mixing should be somewhere in the ratio of 1: 25, 30 or 35, depending on the type. If we are talking about synthetic analogs, then the proportion will be 1: 50 or 80 That is, a certain amount of oil is dissolved in the volume of gasoline.

Appointment

Engine oil is a special blend of solvent and friction-reducing additives. They form a certain viscosity and DO NOT allow the composition to thicken when the temperature is lowered. Usually oils are specially colored in different colors: green, red or blue. This allows them not to be confused.

Please note that they may vary in composition, so petrol trimmer oil will be labeled “for gardening”. In addition, it may still differ in marking: “2T” or “4T”. The first is two-stroke oil that is filled into the corresponding engine. And the second is intended for pouring into the crankcase.

Varieties

The oil that is poured into the engine may differ in the production method. According to this criterion, it happens:

Mineral. this type is obtained during the processing of petroleum products;
Synthetic. it is obtained by processing or synthesizing gas;
Semi-synthetic. this type has more advanced characteristics due to the introduction of synthetic-based components into it.

Lawnmower oil refers to formulations intended for use in air-cooled engines that have a combustion chamber volume of 50-200 cubic centimeters. In addition, any two-stroke oil may differ from analogs in additives, which give it certain additional characteristics. They are of the following types.

Antiwear. The main task of the oil will be to reduce wear of parts during the operation of the device.
Antioxidant. They DO NOT allow oxidation to occur and make it possible to maintain the performance of the oil for a long time.
Anti-corrosion. Their job is to prevent corrosion from forming on engine parts.
Friction modifiers. These additives can significantly reduce the coefficient of friction.

Recently, when purchasing oil for dilution with gasoline, users are very often faced with the fact that special letter abbreviations are applied to the canister. These designations are made within the framework of the API classification. Consider what types of oils exist in accordance with it.

And it is used for air-cooled lawn mowers, the engine capacity of which is no more than 50 cubic centimeters. It can be used Not only for mowers, but also for mopeds, lawn mowers and other types of equipment. For a petrol trimmer, this is the optimal solution.

TB is used to refuel a chainsaw, scooter, moped or motorcycle, the engine of which does NOT exceed 200 cubic centimeters. Can also be used for refueling petrol trimmers.

TC is suitable for thinning with gasoline and pouring into a snowmobile, motorcycle and other types of equipment.

TD is intended for refueling boats, yachts and gyro scooters.

But in addition to this classification, other letter designations of the FA-FD type are often found. It should be said that the API is an American standard that is used in Europe. But there is a discrepancy between European and American smoke emission regulations. For this reason, additional letter designations should be taken into account.

FA can be used in countries where minimum exhaust gas emissions are required by law. Faint smoke may be emitted when using oils with this mark.
FB. can be used in countries where the restrictions on the emission of smoke and gases are much stricter. In this case, the smoke will practically not be emitted.
FC. smoke of a transparent color appears here, as the human eye cannot notice.
FD is a special category of oils for 2-stroke engines, they do not create smoke at all. They have enhanced chemical characteristics. Usually this oil is used for mixing with gasoline and subsequent refueling of boats and yachts.

In addition, oils come in two more categories:

Selfmix;
Premix.

In the first case, this will mean that it is necessary to carry out self-mixing, which does not require shaking, and in the second case, you will need to do it too.

Petrol trimmer oil: types and recommendations for use

Gasoline trimmers are among the most popular mowing tools. They are easy to use, mobile, allow the person NOT to depend on an outlet and show excellent results in the places where they are used. But for the stable operation of a gasoline trimmer, high-quality consumables are needed. In particular, we are talking about gasoline and oil. It is in the last component that we will talk in this article.

Tips for choosing

Now let’s try to understand how to choose a quality trimmer oil that runs on gasoline. The main feature to look out for is the base number. This moment excludes oxidation of the parts in which friction is observed, and slows down their deformation as much as possible. The more this compound is used, the faster it loses its alkalinity and becomes more oxidized. The optimal indicator of acidity (PH) is a value of at least 8-9 units.

The second important factor, which also has a serious impact on the performance of the gasoline trimmer, is the viscosity of the oil. This characteristic determines the ability to use the device at different temperatures. Summer brands of oils begin to thicken already with a minimum temperature drop.

The third point, the importance of which should not be underestimated, is the flash point. This indicator should NOT be less than 225 degrees. Otherwise, the composition will burn out very quickly and the load on the piston group will begin to increase, which will cause its accelerated wear. Also, 4-stroke oil will not work for 2-stroke. Namely, the latter type of motors is used in the vast majority of lawn mowers.

If we talk about manufacturers, then you can make a small rating, which will allow you to navigate the formulations offered by various manufacturers. For example, Stihl offers quality synthetic and mineral oils, which have already proven themselves as an excellent solution at any time of the year.

Shell Helix Ultra oil is considered very good. Experts note its high characteristics and excellent indicators of alkalinity and viscosity. In addition, the products of such brands as Oleo-Mac, Motul, Hammerflex, Echo are considered worthy. If we talk about the products of domestic brands, then you should pay attention to Lukoil oil. Its price is several times lower than foreign counterparts, but at the same time it has high quality and good technical characteristics.

How to use?

For the proportion of oil used, see above. Let’s say right away that you should not deviate from the indicated values and dilute gasoline by eye. At best, you just need to change the oil, and at worst, engine damage cannot be avoided.

It is important to be able to prepare the mixture correctly. It cannot be poured into the gas tank. It is better to pour the oil into a special container that already contains gasoline. A plastic bottle of mineral water is perfect for this. It is very important here that it is clean, which is why beer or milk bottles will not work. And it is better that it be a liter or two-liter, since it will be difficult for many to calculate how much oil to fill in a 1.5-liter or 1.25-liter bottle. You will also need to have a syringe on hand that will function as a dosimeter. It is best to take a regular medical one for 10 or more cubes.

Now explain step by step how to make a good gasoline trimmer oil.

First, you should find out exactly what type of oil is required for a particular braid model, as well as find out the exact ratio of gasoline and oil to create a mixture.
Then you need to fill the container. The container should not be filled with gasoline to the end, because oil must still fit there;
Now we draw the required amount of 2-stroke oil into the syringe and pour it into a bottle of gasoline. You cannot do the opposite, otherwise all ingredients will need to be replaced, and the mixture will need to be done again.
Close the bottle with a lid and stir. Here it is important NOT to forget that you need to stir the mixture if the words Premix are on the bottle with oil. If it says Selfmix, then after mixing the substances, everything is poured into the tank.

Now all that remains is to refuel the petrol trimmer, and you can carry out the necessary work.

For information on how to choose oil for gasoline trimmers, see the following.

Fuel mixture: the proportion of oil and gasoline for the chainsaw

The chainsaw engine is the “heart” of the tool, so it is very important to use a properly prepared fuel mixture.

The fuel mixture for a chainsaw is prepared from two components. oil and gasoline. Chainsaws are equipped with two-stroke engines, so oil is not added to the lubrication system (as in a four-stroke engine), but directly to gasoline. At the same time, it is very important to observe the correct proportions of ingredients, of course, in no case should you try to work on pure gasoline, because in this way you will very quickly “kill” the chain saw.

If we talk about what kind of gasoline to pour into the chainsaw, then it will be optimal to use fuel with an octane rating of A-95, in this case the savings on fuel can turn out to be deplorable. Often European manufacturers indicate that it is possible to use A-90 or A-92 gasoline, but in the post-Soviet countries the quality of gasoline is inferior to European, therefore, in our realities it is better to use higher quality gasoline.

As for the proportion of the oil-oil mixture itself, everything is simple here: you must follow the instructions for the tool. All manufacturers of chainsaws indicate the required ratio in the instruction manual or in the passport of the tool, in addition, the proportions for refueling the chainsaw may differ depending on the model of the chain saw. As a rule, the proportion of oil and gasoline to a chainsaw of famous manufacturers is a ratio of 1:40 or 1:50, which means 1 part of oil for, for example, 40 parts of gasoline. Now arithmetic 1 liter of gasoline = 1000 ml of gasoline, divide by 40 and we get 25 ml of oil. If you do the same to a 1:50 ratio, you get 20 ml of oil per 1 liter of gasoline. As for budget chainsaws made in China, the situation is slightly different. The ratio of gasoline to chainsaw oil made in China 1:25, that is, divide 1000 ml of gasoline by 25, we get 40 ml of oil. The thing is that in branded chainsaws, a solid assembly and the distance between the pistons and cylinders in the engine is much less than in Chinese chainsaws, therefore the required amount of oil differs almost twice.

In order to measure the correct amount of oil, use a conventional medical syringe of sufficient volume.

Another subtlety. Fill the dry gas canister with gasoline first and then oil. The procedure, on the contrary, is fraught with a low quality fuel mixture, because the oil is denser, it will stick to the bottom of the canister. what a good mixing here.

Be sure to prepare the fuel mixture in the Canister and fill the ready-made special fuel into the gas tank! Never ready and DO NOT mix it directly in the fuel tank of your chainsaw!

If you figured out the question of how to breed gasoline for a chainsaw, then on storage conditions and shelf life of the fuel mixture it is worth saying a few words. It is best and easiest to prepare a petrol-oil mixture for 1 liter of gasoline, it is recommended to do this immediately before working with the tool. Chainsaw fuel tanks have a volume of 0.3 to 1 liter. In the conditions of domestic use, the entire volume of the prepared fuel mixture is rarely used in one session, so the remainder can be saved until the next session. It is necessary to store the fuel mixture in a special Canister for gasoline, in a dry, dark place. It is optimal to count that the shelf life of the finished mixture will be 7-10 days. The fact is that the oil on the market now is NOT synthetic, but organic, that is, natural. After 10 days, all lubricating properties are lost, gasoline simply “eats” the oil. Naturally, it is no longer possible to use such fuel, this can cause breakdown and failure of the chainsaw.

At the end of the work, it is necessary to drain the fuel mixture, start the chainsaw, the tool will stall (so that there is a dry carburetor in the saws) and now you can leave it in the next operation session.

Unsuitable fuel mixture must be disposed of.

Consequences of violation of the ratio

How accurately you will observe the proportions of the oil-gasoline mixture recommended by the manufacturer depends on the service life of the motor scooter engine. The fact is that the fuel mixture enters the cylinders in the form of gasoline-oil mist. And the task of the oil composition is to lubricate the moving and rubbing parts and surfaces of various parts in the cylinder. If it suddenly turns out that there is not enough oil, but somewhere it will not be enough at all, the parts touching dry will begin to damage each other. As a result, scuffs, scratches and chips are formed, which will certainly lead to complete or partial engine failure (for example, it can jam).

In the opposite case, when too much oil enters the engine, it does NOT have time to completely burn out, settling on the cylinder walls and turning over time into solid particles. coke, slag and the like. As you might guess, this also leads to engine failure. The most important thing is that you must not allow. even a single violation of the proportion towards the lack of oil. It is better to pour a little oil 10 times than not to top up just once. It often happens that this time is quite enough to break the engine.

Standard proportions

First of all, it is necessary to take into account the information that the manufacturer recommends, since in the event of a failure of the lawn mowers, you can present your claims to him, and not to a third-party source. If there is no instruction in the passport, and even more so if there is no passport, we recommend that you look for another trimmer model in a more reliable seller.

For all other cases, when you have a lawn mower model in your hands and there is no way to find out its technical features, there are standard proportions of the Most probable fuel mixture components for a two-stroke engine. Basically, for THESE units, AI-92 gasoline and a special synthetic oil are used, which contains a solvent for better mixing with fuel. This oil evaporates slowly and has the ability to completely burn out in the cylinder, Do not leave carbon deposits.

The standard ratio of synthetic oil to gasoline is 1: 50. This means that 5 liters of gasoline need 100 ml of oil, and in accordance with this, oil consumption per 1 liter of gasoline is 20 ml. Knowing the amount of oil required to dilute 1 liter of fuel, you can easily calculate any rates when preparing fuel for the trimmer. When using mineral oils, a ratio of 1: 40 is most often the standard. Therefore, 1 liter of fuel will require 25 ml of such oil, and for a 5-liter canister. 125 ml.

When working with lawn mowers, a person with little experience in operating such equipment will not be difficult to determine and correct the actual amount of oil required for a particular model. You should only pay attention to Exhaust gases (their color, odor toxicity), cycle stability, engine heating and developed power. details about the consequences of incorrect mixing proportions of gasoline and oil can be expected in another section of the article. There are variants of lawn mowers running on AI-95 gasoline. This should also be considered.

How to choose for lawn mowers?

lawn mows are a fairly common technique for combating weeds in summer cottages, in road gardens and housing and communal services. These devices have two more names. trimmer and lawn mower. These units differ in their engines. The more expensive ones have four-stroke engines, all the others have two-stroke engines. Of course, the latter are the most popular among the population, since they are simpler in design, and lighter in weight, and much cheaper than their four-stroke competitors. However, two-stroke models are inconvenient in that the fuel mixture for them must be prepared manually, maintaining a strict dosage between gasoline and oil. In four-stroke analogs, the mixing of THESE components occurs automatically, you only need to fill the gas tank and oil tank with the corresponding substances. Let’s consider the issue of the correct refueling of two-stroke lawn mowers, since it depends on how effective and long the operation of such a unit will be.

Mixing rules

And now about how to mix the components correctly. However, it would be more logical to start with an analysis of common, but absolutely unacceptable mistakes, which many owners of this mowing unit “sin” with. The following actions are considered as mixing errors.

Adding oil to the fuel already in the mowers’ gas tank. Similarly, a homogeneous fuel mixture will NOT work. Perhaps it will work, if only then shake the trimmer for a long time. But it is unlikely that someone will do this by taking the weight of the unit.
First pour oil into a mixing container, and then add gasoline to it. Gasoline has a lower density than oil, so if it is poured into the oil, it will remain in the upper layer, that is, natural mixing will NOT occur. Of course, it will be possible to mix later, but much more energy will be required than if it were done the other way around. pour oil into the filled gasoline.
Ignoring accurate measuring instruments for taking the required quantities of ingredients used. In other words, diluting the amount of oil or gasoline “by eye” is a bad habit when operating motor vehicles.
Take empty drinking water bottles for preparation of the fuel mixture. Such a container is made of too thin polyethylene, which can be dissolved in gasoline.

Considering all of the above, we recommend using the following rules when mixing a fuel mixture for two-stroke trimmer engines.

Use only clean containers made of metal or special plastic for storage of gasoline, oil, ready-made fuel mixture and its preparation.
Use for filling gasoline into the LEIKOME dilution container in order to avoid spilling, and for adding oil. in a measuring container with volume risks or a medical syringe for 5 and 10 ml.
First, pour gasoline into the canister for preparing the fuel mixture, and then oil.
To dilute the mixture, first pour only half of the planned volume of gasoline into the container.
Next, add the entire amount of oil required to prepare the mixture to the gasoline.
Mix the contents of the dilution container thoroughly. It is best to stir by making circular movements with a tightly closed container. You should not stir the fuel inside the canister with any foreign object, since it is not known what material this object is made of, what reaction it can enter into with an ingredient in the mixture, how clean it is.
Add the rest of gasoline to the mixed mixture and mix thoroughly again.
You can refill the fuel tank of the lawn mowers.

It must be borne in mind that the ready-made fuel mixture does not have to be stored for more than 14 days, since it loses its properties, stratifies and evaporates, which leads to changes in proportions, and therefore, deterioration of trimmer performance.

How to choose for lawn mowers?

For two-stroke engines, lawn mowers use AI-92 or AI-95 gasoline. Most often. the first of the named. There is always information about this in the technical data sheet of the product. If, for some reason, it is not known exactly on which gasoline the trimmer should work, you can choose it by testing both brands of gasoline in action. Global changes in the engine will not happen from this, and it is quite possible to determine what kind of gasoline and or another model of the unit “likes” more, according to some factors. This will be shown by the developed power, and throttle response, and engine heating, as well as its stable operation at all speeds.

But it is much more difficult to determine the proportions of oil to a certain volume of gasoline. In this case, you need to know at least something in the equipment manufacturer. And already according to the standard proportions for this manufacturer, select the proportion for a specific model, taking into account the type of oil.

For example, for Chinese low-power trimmers, two ratios are mainly used. 1: 25 or 1: 32. The first is for mineral oils, and the second is for synthetic oils. In the choice of standard proportions for lawn mowers of European and American manufacturers in connection with the type of oil, we have already told you earlier. According to the class of oils for household trimmers, you need to use TB oil according to the API classification. For more powerful. class TS.

For the ratio of gasoline to oil required for lawn mowers, see the following.
