What Kind Of Oil To Put In A Husqvarna Lawn Mower

What kind of oil to put in a Husqvarna lawnmower One of the most pressing questions for motorists. Is it worth changing the transmission fluid in the gearbox of your iron horse and when

Recommendations for the selection of oils from specific manufacturers

Lawn mower manufacturers in the instructions for them must indicate the type that is used in their technology, as well as the frequency of oil changes, usually in hours. Usually manufacturers indicate their branded lubricants and they should be used if you want to keep the warranty on the equipment. But often manufacturers also indicate the general characteristics of lubricants and then you can choose similar lubricants from more widely available automotive oils.

The one recommended by the manufacturer is considered the best for any engine. World renowned Shell Helix Ultra . For 40 years Shell has been developing a new technology for producing synthetic oil from natural gas. Pureplus technology has resulted in an improved base oil composition. On its basis, with the addition of the necessary additives, the leading manufacturers recommended for their equipment are obtained.

Lawn mower features

The engine oil in the mower engine is distributed by the crankshaft: it is scooped out of the crankcase and sprayed onto the parts. Due to this design, the viscosity of the lubricant must be sufficient to retain the oil film on the parts, while it must not be too thick to interfere with the movement of parts or form a hard crust.

On the other hand, lawn mowers operate mainly in positive ambient temperatures and the load on their engines is not as severe as on car engines. For lawn mowers, most often a cold start is not required in the cold, which greatly reduces the service life of a car engine and requires low-temperature properties from lubrication.

The first refueling is intended to run in the engine after five hours of operation, it is replaced, after which it is possible to work on the new grease for the whole season. In the future, the replacement is done according to the regulations after a certain number of engine hours, or it is drained at the end of the summer season and a new one is poured in the next year.

What kind of oil should I put in my lawn mower?

Internal combustion engines used in lawn mowers come in two and four strokes. When changing the engine oil in lawn mower engines, owners have a question: what kind of engine oil should be put into the mower? Today we will take a closer look at this issue and start first with four-stroke engines.

General Guidelines for Choosing Lawn Mower Oil

Based on the above design features of the engines, it is best to use a special lawn mower oil for lubrication, and it should be suitable for the temperature conditions in which the unit will be used. The best option is a specialized grease of SAE 30 grade. It is used at temperatures above 5 degrees.

If a special one is not available, then automotive lubricants of the class can be used:

• SAE 15W-40
• SAE 20W-50

These lubricants are also designed mainly for positive ambient temperatures and a maximum value above 35 degrees.

According to the type of lubricant, mineral and semi-synthetic are allowed. Fully synthetic would be too expensive. Quality level of performance properties according to API SF, SG, SH, SJ and higher. For four-stroke garden machinery engines, the label must be marked 4T.

Changing the engine oil in two-stroke lawn mowers

The two-stroke engine is usually mounted on trimmers (manual grass clippers). These devices are small in size and weight, so the number of parts in them is kept to a minimum. They do not have a separate oil reservoir and need to mix gasoline and oil. Here, amateur performance is no longer appropriate, it is necessary to use only a special one for two-stroke engines and mix it with gasoline in the proportions specified in the operating instructions for the trimmer.

Once again, we draw attention to the oil cans for two-stroke engines, the marking MUST be indicated 2T!

The fuel mixture for two-stroke engines is prepared as follows:

1. The exact amount of gasoline is poured into the canister (for example, for a 5 liter trimmer),
2. Then, using a dispenser, add the oil (semi-synthetic 100 milliliters)
3. Cover with a lid and mix well

The finished fuel mixture can be stored for no more than two weeks in a metal or polypropylene container.

Do not use plastic bottles for storage! Polyethylene dissolves in gasoline and then, getting into the combustion chamber, increases carbon deposits in the engine. With prolonged storage of the fuel mixture, it loses its properties due to chemical reactions. There is an increased risk that the engine will not start on old fuel.

We hope our review has helped to answer the question that concerns you: what kind of oil should you put in a lawn mower? We ask you to share your best practices for changing engine oil in lawn mowers under the review in the comments below.

What kind of oil to pour into the mower?

Everyone knows that a car engine requires special care to ensure a long and trouble-free life of the engine. The same rule applies to the motor of a gasoline lawn mower: depending on whether you have a trimmer or a large four-wheel mower, you will be faced with the problem of choosing an oil. What are the basic requirements for lawn mower engine oil?

How to choose your lawn mower oil?

As with any unit, there is an instruction for the lawn mower, which contains not only the main characteristics of the tool, but also the rules for caring for it. So, the instructions will say that only specialized oil should be used for lawn mowers. And some manufacturers insist on using the same brand of oil as the lawnmower itself.

In fact, this fact turns out to be just a marketing ploy by manufacturers, and both automobile and motorcycle engine oil for four-stroke engines can be suitable for a lawn mower. It is enough just to follow the basic rules:

1. The oil must be mineral or semi-synthetic. Fully synthetic oil can burn the engine, so it is best not to use it at all. A lot of sludge is generated when the mower is running on mineral oil, so we advise you to opt for semi-synthetic oil. In addition, mineral oil is difficult to find today.

2. The viscosity of the oil should not exceed SAE 30 or 10w30, and the quality category should vary between SE and SJ. Viscous oil can disrupt engine performance, however, less viscous oil can also be affected. All these indicators are necessarily indicated on the packaging.

3. Select oil based on operating temperature conditions. If you mow in cold weather, the viscosity of the oil may be higher than the above, but the next time you turn it on, you will have to change the oil to the correct one.

In lawn mowers with four-stroke engines, oil is poured into a special crankcase and is never mixed with gasoline, since the design of such a gas mower does not imply a mix of oil and fuel. On the contrary, it can cause engine damage. It is enough to change the oil once a season, since the crankcase usually holds from 450 to 600 ml of oil, this is enough for processing large areas. However, do not be lazy to check the oil level before each use of the tool.

How is oil used in two-stroke lawn mowers?

As a rule, a two-stroke engine is installed on trim tabs, and since their design does not imply the presence of unnecessary parts, a separate oil container is not provided. What should be done in this case? Prepare fuel mixture.
For lawnmowers with a two-stroke engine, the same rules apply as for their larger counterparts, with one exception, oil must be purchased for units with a two-stroke engine.

Each trimmer (or instructions for it) indicates the mixing ratio of fuel and oil: from 1:32 to 1:35. This rule only applies to mineral oil! And since it is quite difficult to find it now, and it can scare off the cost, semi-synthetic or even synthetic oil is most often used. Please note that the mixing proportions in this case change, and become 1:50. If in doubt, carefully study the packaging of the oil, it usually contains these data. You should focus on them. To prepare the mixture, it is enough to pour in 100 ml of oil into five liters of gasoline, this should be enough for a whole season of regular mowing. If not, repeat the procedure.

Selection recommendations

It is best to use a specially designed oil for 4-stroke lawn mower engines in accordance with the ambient temperatures in which the equipment will be used. For example, are quite suitable for four-stroke mowers in terms of their operational parameters specialized grease grades 10W40 and SAE30, that can be used at ambient temperatures ranging from 5 to 45 degrees Celsius.

In the absence of specialized oils, you can use other classes of oils used for cars. These can be grades SAE 15W40 and SAE 20W50, which are also used at positive temperatures., but only their threshold is 10 degrees lower than specialized ones (up to 35 degrees). And also for 90% of the available models of four-stroke lawn mowers, SF oil will do.

Four-stroke lawn mower engine oil containers must be marked with a 4T mark. Synthetic, semi-synthetic and mineral oils can be used. But most often they use semi-synthetic or mineral oil, since synthetic oil is very expensive.

And in order not to guess what oil to pour into the engine of your mower model, it is better to look at the instructions. The required type of oil and the frequency of its replacement are indicated there. It is recommended to use only the types of oils specified by the manufacturer until the expiration of the warranty repair period, in order to maintain the warranty issued. And then you can choose something more affordable, but, of course, not inferior in quality to branded oils. You should not save on oil quality.

Why do you need a lubricant?

Gasoline lawn mower engines are internal combustion engines (ICEs), in which the driving force transmitted from the ICE to the working bodies (cutting knives) is generated by the energy generated in the combustion chamber of the cylinder when the fuel mixture is ignited. As a result of the ignition, the gases expand, forcing the piston to move, which is associated with the mechanism for further transferring energy to the final organ, that is, in this case, the lawn mower knives.

In the engine, therefore, many large and small parts are mated, which need lubrication in order to, if not completely prevent their abrasion, destruction, wear, then at least as much as possible slow down these processes negative for the mechanism.

But over time, this cannot be avoided, since the development of gaps in the mates still occurs. And the better the oil, the longer the service life of the garden equipment will be. In addition, with the help of high-quality lubricants, the following positive phenomena occur:

• Better cooling of the engine and its parts, which prevents overheating and thermal shock;
• Engine operation is guaranteed at high loads and with a long time period of continuous grass mowing;
• The safety of internal engine parts from corrosion is ensured during seasonal equipment downtime.

How often do you need to change the lubricant?

As noted above, the operating instructions for garden equipment with a 4-stroke engine must indicate the frequency of oil changes. But if there are no instructions, then they are guided first of all by the number of hours that the technique has worked (engine hours). Every 50-60 worked hours, you need to change the engine oil.

However, in the case when the plot is small and you can process it in no more than one hour, it is unlikely that for the entire spring-summer season the lawn mower will work even half of the operating hours from the norm, unless it is rented out to neighbors. Then the oil must be replaced when the equipment is being preserved in the fall before the winter period.

6. What kind of oil should not be added?

Lawn mowers have long taken their place among the necessary equipment among the owners of country and private houses, as well as employees of park management institutions. In the summer, this technique is used quite intensively. For the reliable and durable operation of lawn mower engines, the quality of fuels and lubricants, in particular oils, is important. Oils for 4-stroke engines of this type of garden machines are discussed in this article.

Features of the four-stroke engine

Lawn mower gasoline engines are divided into two groups: two-stroke and four-stroke. Their difference in the way of filling the oil is as follows:

• A lubricant for two-stroke engines must be pre-mixed with gasoline in a separate container and in a certain ratio, thoroughly mixed, and after all this, it must be poured into the fuel tank of the car;
• Grease and gasoline for four-stroke are not pre-mixed, these fluids are poured into separate tanks and work separately, each according to its own system.

Based on this circumstance, the requirement for oil is also special here. It should retain its properties for a long period, when, as for the lubricating composition of a two-stroke motor, the main quality criterion, in addition to the basic properties, is the ability to burn without a trace, leaving no carbon deposits and deposits.

Oil change

Changing the lubricant in a lawn mower engine is not as difficult as changing the oil in a car. Everything is much simpler here. The work algorithm is as follows.

1. Prepare enough fresh oil for replacement. Typically, many lawn mowers have no more than 0.6 liters of oil in the lubrication system.
2. Start the unit and let it idle for a few minutes to warm up the oil so that it becomes more liquid. This promotes better drainage.
3. Switch off the engine and place an empty container under the drain hole from the crankcase to collect the used oil.
4. Unscrew the drain plug and let all the oil drain. It is recommended to tilt the device (if possible or appropriate) towards the drain.
5. Screw the plug back on and move the machine to a level surface.
6. Open the filler hole on the oil tank and fill it to the required level, which is controlled by a dipstick.
7. Tighten the tank cap.
