Best Lawn Mower Oil and Oil Change Tips

What’s the best oil to use in a lawn mower?

4-stroke engines have a more complicated design than 2-stroke engines. Four-stroke mowers are more powerful and therefore more efficient. Such engines are more economical and run cleaner, because they have a better control of air inlet and outlet cycles.

Due to the fact that fuel escapes during injection and compression, some of it is wasted in a 2-stroke cycle. This is not the case with the other engine. It draws gasoline into the closed loop. 2-stroke engines are filled with oil and gas mixtures, which reduces combustion efficiency and increases emissions in the form of burnt harmful oil. They mix fuel and oil, which has a negative effect on service life. Because of general circulation, these lawnmowers can be operated in all conditions.

The 4-stroke engine has a specialized lubrication system. It injects engine oil from a separate container. The oil is separated from the fuel so the engine is lubricated better. Automotive engines mainly run on a four-stroke cycle.

The simple design and fewer moving parts in 2-stroke brushcutters makes them easier to service and repair. They are much lighter.

In two-stroke engines, due to the fact that a dirty combustion product is formed after the combustion of fuel and oil, there is more wear and tear on the engine system. As a result, they break down more quickly. The cost of lawnmowers with this engine is lower, but it increases per hour of work due to the fact that you have to spend extra money on oil, as well as because of the low fuel economy.

Tips for lawn mower oil selection

Almost every modern manufacturer of garden tools also produces oil for it. It comes under the same brand and it’s recommended to use it. It should be understood that it is not the brand itself that produces the lubricant, but a third-party company, but according to studies and tests, it is this product that fully meets the requirements of the company that makes the tool. The problem is that such oil is usually more expensive than conventional, but in terms of composition and quality it is easy to find an analogue, if you know the nuances to look at.

The most important aspect. the set of additives used. It differs depending on the type of engine, but with few exceptions the composition of oils is the same.

It is much more important not to fall for a fake, of which, unfortunately, there are many on today’s market. It all depends on the brand. Top companies pay a lot of attention to protecting their product. This can be holograms, complex container texture and so on.

As for the question, how much oil to pour into the engine, relevant only for 2-stroke models, you should always follow the manufacturer’s advice. He specifies them in the instructions. But it happens that the data from the passport of the lawnmower and from the oil bottle are different. In this case, the information from the bottle is priority. On average, the ratio of gasoline to oil is 1:50.

Choosing lawnmower oil

Every summer begins the season of active use of gasoline equipment. Even in our country in recent years began to actively use lawn mowers, previously known to us only by TV movies.

It goes without saying that users of such a tool have a lot of problems, since not everyone has the experience to operate it properly. In particular, a particular headache is caused by lawnmower oil, the choice of which is far from easy. By the way, in this connection it would be worthwhile to say that many buyers set themselves fundamentally wrong criteria for the selection of lubricants, as they poorly imagine the basic performance characteristics of the equipment they use.

Very often they forget that even the lawnmower oil should be chosen, focusing also on the temperature performance of the environment.

It is known that any lubricant for four-stroke engines has to conform to certain viscosity indexes SAE. Of course, lawn grass grows very badly at subzero temperatures, so when buying you should focus on those products, whose indicator in this parameter corresponds to the summer operation.

Most manufacturers say that SAE 30 lawnmower oil is the best. The use of less viscous varieties for cold climates and thicker greases for hot regions is also not welcome. Why?

It’s the construction of these devices. To reduce the price and simplify their production, the designers have excluded the oil pump from their composition. As a result, all the moving parts of the engine are lubricated thanks to the crankshaft, which during its movement “scoops it up” from the crankcase, distributing the lubricant evenly by friction over all the parts. That’s why you can’t buy lawnmower oil at the first store you see, because later you can be “happy” with the bill for its repair.

So, if the consistency of the lubricant is too thin, it will simply flow from the crankshaft back into the crankcase. If it is too thick, then over time, such a substance can turn into an amonic solid mass, which also will not lead to anything good.

Cars are much better protected from such troubles, as a special oil pump is responsible for the evenness of engine lubrication. Theoretically, all the oil for lawnmowers can be used in cars, but the standard products for cars will not always suit other equipment.

Fortunately, today almost all specialty retailers sell specialized SAE 30 grade grease. But these outlets are not found in all cities, let alone in smaller towns and villages. So which oil to fill your lawnmower with in the absence of specialized options?

Experts say that SAE 15W-40 and SAE 20W-50 class lubricants are best suited for this purpose. And the purchase of “synthetic” or mineral oil does not really matter, because lawn mowers are not used in as harsh conditions as race cars have to drive.

Every summer is the season of using gasoline-powered machines. Even in our country in recent years began to be actively used lawn mowers, previously known to us only from TV movies.

Of course, users of such tools have a lot of problems, because not everyone has experience in using them correctly. Lawnmower oil in particular is a real headache because it is not so easy to choose the right oil for one’s lawnmower. By the way, it would be worthwhile to say that many customers set themselves fundamentally wrong criteria for grease selection, as they have a poor understanding of the basic performance characteristics of the equipment they use.

They often forget that even the lawnmower oil should be chosen according to the ambient temperature.

It is known that any lubricant for four-stroke engines should meet certain viscosity indexes SAE. Of course, lawn grass grows very poorly at sub-zero ambient temperatures, so when buying it is necessary to focus on those products, whose indicator on this parameter corresponds to the summer operation.

The next stage of lawnmower maintenance: cleaning

A quality lawnmower cannot be maintained without elementary cleaning of the deck and motor from grass.

Getting rid of the deck of vegetation

The grass itself has an incredible corrosive effect on the unit, so it is necessary to periodically clean the DEKO

It is important to understand that the wet lawn must not be mowed in any case, because then the negative effects will increase by 2 times

Dry vegetation will fall off the object by itself, and it will be possible to clean it with an air compressor or blower. Some models are equipped with a special flushing connection, which saves the user from additional hassle.

Getting rid of vegetation

Since mower motors are supplemented with air cooling, the entire system will work properly only if the ribs will not be contaminated. Otherwise expect overheating and rapid breakdown.

Features of garden equipment engines

These motors work in two modes. The first one is idling, when we first start the machine, and the maximum RPM mode. Therefore, the garden grease must maintain a stable oil film at constant high loads.

Lubrication of four-stroke garden motors is performed by spraying, because no oil pump is installed on such engines. For this technique, the important indicator will be the viscosity of engine oil. That’s why viscosity 30 is the most common.

Important: The engine of garden equipment: a grass trimmer or lawnmower, is only air-cooled. Here, the lubricant must operate at high temperatures and prevent overheating of the engine, that is, in fact, save from a thermal shock.

right, your, lawnmower

Some motors are finicky about sulfated ash, which is especially true of two-stroke engines. Such limits are set directly by the manufacturers of garden equipment, despite the fact that you can already find four-stroke engines with the requirement of low ash. It is done only for ecology.

Pretty strict environmental safety requirements. However, when looking at Russia, this process is not yet widespread. In the European market, in order to get in on some kind of garden maintenance contract within the city limits, only certified oils and lubricating fluids need to be used. There materials should cause minimal damage to the soil and plantings.

General recommendations for choosing lawnmower oil

Based on the above design features of the engines, it is best to use a special oil for lawnmowers, and it must meet the temperature conditions in which the unit will be used. A specialized SAE 30 grade lubricant is considered optimal. It is used at temperatures above 5 degrees.

If special is not available, you can use automotive grade lubricants:

These lubricants, too, are designed mostly for positive ambient temperatures and a maximum above 35 degrees.

By type of lubricant. mineral and semi-synthetic are acceptable. Fully synthetic would be too expensive. API performance quality level. “SF”, “SG”, “SH”, “SJ” and higher. For four-stroke garden equipment engines, the label should be marked “4T”.

What oil to put in your lawnmower?

Everybody knows that a car engine requires special care, which would guarantee long and trouble-free life to the engine. The same rule applies to the gasoline lawnmower motor: whether you have a grass trimmer or a large four-wheel mower, you’ll run into the problem of choosing an oil. So what are the essential requirements for lawnmower engine oil?

As with any machine, the lawnmower comes with a manual, which describes not only the main characteristics of the tool, but also how to take care of it. So, in the instructions will be written that for lawn mowers, you need to use only specialized oil. And some manufacturers even insist on using oil of the same brand as the lawnmower itself.

In fact, this fact turns out to be just a marketing move by manufacturers, and for lawn mowers can suit both car and motorcycle engine oil for four-stroke engines. It’s enough to follow the basic rules:

Oil must be mineral or semi-synthetic. Fully synthetic oil can burn the engine, so it’s best not to use it at all. When the lawnmower works, mineral oil tends to produce a lot of sludge so we recommend you use semi-synthetic oil. Besides, mineral oil is hard to find these days.

Oil viscosity should not exceed SAE 30 or 10w30 and the quality grade should range between SE and SJ. viscous oil can impair engine performance, and so can less viscous oil. All these indicators are necessarily indicated on the packaging.

Choose your oil depending on the temperature conditions. If you mow in cold weather, the oil viscosity may be higher, but the next time you use it you have to change it.

In lawnmowers with four-stroke engines oil is poured into a special sump and never mixed with gasoline, as the design of such gasoline lawnmowers does not imply a mix of oil and fuel. On the contrary, it can cause engine damage. It’s enough to change oil once a season, since the crankcase normally holds 450 to 600 ml of oil. enough to cover a large area. However, do not be lazy to check the oil level before each use.

How oil is used in lawnmowers with two-stroke engines?

As a rule, the two-stroke engine is installed on grass trimmers, and since their design does not imply the presence of extra parts, a separate container for oil is not provided. What to do in such a case? Prepare fuel mixture.For lawn mowers 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.

On each trimmer (or in the instructions for it) indicated the proportions of mixing fuel and oil: from 1:32 to 1:35. This rule is only true for mineral oil! As it is pretty difficult to find it now and the cost can scare away, semisynthetic or even synthetic oil is used most often. Note, that the mixing ratio in this case changes, and becomes 1:50. If in doubt, look carefully at the oil package, which usually has this information on it. You should use these as a guide. To prepare the mixture it is sufficient to pour 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.

When choosing a means to care for the grass on the garden or dacha plot, the owner faces the choice. what to buy. a lawnmower (electric mower) or a wheel mower.

The abundance of information on the Internet and advice from sellers makes a perfect mess in the mind of a potential buyer, based not only on experience (including negative), but also on prejudice and outright ignorance.

Lawn mowers are for strong men only! (like Schwarzenegger).

A lawn mower is a two-stroke petrol motor with an output of 1-2 liters.с., located at one end of the tube. And on the other end is a cutting element, a disc or a spool of fishing line. The total weight of the machine is several kilograms. And the suspension point is made so that even a fragile girl can handle a lawn mower. The grasshopper is very well balanced.

Fueling two-stroke engines and preparing a fuel mixture are wonders of alchemy, inaccessible to mere mortals

Two-stroke engines require for their power not just gasoline, but a fuel mixture of gasoline and oil (special, for two-stroke engines). This is not at all in short supply, two-stroke motor oil is sold at any auto parts store and any place that sells these very lawn mowers Ask the salesman and he will lead you to the shelf with these oils. Eyeballs are blown away by the choice.

And making a gasoline-oil mixture is no more complicated than dressing a salad with mayonnaise. As a rule, the ratio of oil to gasoline in the mixture ( 1:32. 1:35) is indicated on the mower (or chainsaw). This ratio is for mineral oils.

They’re still hard to find for two-stroke engines except for motorcycle engine oils. For oils in small packages for gardening equipment. practically only synthetic oils. And they have a 1:50 ratio (that’s usually what it says on the package).

right, your, lawnmower

You have to follow the recommendations on the oil pack!

To make the fuel mixture you take a canister with e.g. 5 liters of gasoline and fill it up with 100 ml of oil. That is the whole secret. You will have enough fuel for the whole season. If it is not enough. repeat the procedure Pour the mixture into the gas tank and no more problems.

You have to buy only “Husqvarna” oil for your Husqvarna mower

Husqvarna does not have its own refineries. That’s a whole other business.

So she buys two-stroke oil at the refinery in tanks, packs it in small cans and labels it “Husqvarna” And she beats the ignorant with an extra 2-3 for that label.

Other companies like STIHL buy the same oil in the same plant and stick the label “STIHL” on itAnd they charge you 2 to 3 bucks for it too Any two-stroke oil is good for any two-stroke engine!

Lawn mowers are only suitable for perfectly smooth lawns.

No, it doesn’t I thought so too, on my completely unplanned property. The wheel mower turns out to have excellent contour following. The only obstacle is anthills that can be removed with a shovel.

And uneven terrain a wheeled lawn mower handles perfectly. Especially if it has an adjustable cutting height. You set it to maximum and check the area.

Where the blade grabs the ground, you can also work with the shovel.

right, your, lawnmower

The lawn mower has several times the cutting performance of a hand lawn mower. And it’s no more difficult to steer than a stroller. You just walk and guide it. Especially if it’s a self-propelled mower. Even kids can handle it.

Wheeled lawn mowers have 4-stroke engines and are as complicated to maintain as a car.

Wheeled lawnmowers generally have a four-stroke engine. The basic difference between a four-stroke engine and a two-stroke engine is the presence of an oil sump for engine lubrication. That is why it is not necessary to mix oil and gasoline for a 4-stroke engine to work properly.

This circumstance is presented by some dishonest salespeople as an advantage. “there is no need to bother with preparation of fuel mixture”. In doing so, they “nicely” leave out such a detail as the need for at least an annual oil change in the crankcase of a wheeled lawnmower.

The procedure is not complicated, much easier than changing the oil in a car, but more complicated than preparing the fuel mix. Generally speaking, the oil in the lawnmower‘s crankcase should be changed about every 50 hours of operation. The lawnmower has no oil filter and therefore the oil is not cleaned there. That is why the oil change intervals are more frequent.

50 hours per season, on the other hand, is a very long operating time.

The process of changing the oil in a ride-on lawnmower is easy. Before changing the oil it is desirable to give the lawnmower about 10-15 minutes to work, so the oil would warm up and become more fluid.

Any lawn mower has a special screw that covers the drain hole from the engine crankcase. It is usually located under the crankcase filler neck and measuring cup. (marked with an arrow in the photo).

Mower is installed with the inclination towards the drain hole by placing a block of wood or a brick under the housing on the opposite side. After that we unscrew the screw. plug. What would not spill oil on the lawnmower casing, from a plastic bottle cut a chute in which the oil will flow into the substituted container. It is advisable to empty the gasoline from the tank before changing the oil.

After that, screw. stopper unscrewed and let the oil drain by tilting the lawnmower. When the oil has run out, screw it back in. Fill in fresh oil through the measuring jug. Usually it is recommended to use oil with a viscosity 10W40, mineral or semi-synthetic in lawn mowers.

The inexperienced owner of the gardening technique, of course, tends to almost worship the new purchased technique, up to the fetishism. He wants to put better gas and more expensive oil in it. This is a common mistake that leads to a very quick breakdown of machinery!
