Yes, 10w40 oil can be used for lawnmowers and get away without having any problem. Besides the recommended lawnmower oils, you can sometimes try something different like a 10w40 used in the cars. But, using them from the very first time you bought your lawnmower till the end is not recommended.
Can I use 5W30 oil in my push mower?
I have NEVER seen 5W-30 okayed for use in any air cooled small engine except for wintertime temperatures. The first number (10w in 10w30) is how well the oil flows cold. (it will flow the same as cold 10w oil). The second number is the hot flow. You don't want to use 5w30 in a push mower, it'll just burn up, because it's so thin.
Can I use 10W40 instead of 10W30 in winter?
10w40 is too thick at temp to lubricate properly and help with heat dispersion. Air-cooled engines are picky like that. I always use 10w30 in the winter in all my stuff, (but my car) and straight 30w B&S oil in the summer. When the temp doesn't get below 60 at night, you don't see a lot of advantages to multi-vis. Hope that answers your question.
What does 10W30 mean on a lawn mower?
The first number (10w in 10w30) is how well the oil flows cold. (it will flow the same as cold 10w oil). The second number is the hot flow. You don't want to use 5w30 in a push mower, it'll just burn up, because it's so thin.
Why can't I use 10W40 instead of SAE 30?
It's not the weight. It's the API rating. 10W40 does not meet the requirements for small engines. And SAE 30 is on the way out as being recomended. 10W30 & 5W30 are the recomended oils now. The reason is the additives and how well they lubricate. It's not the weight. It's the API rating. 10W40 does not meet the requirements for small engines.
What happens if I use 10W40 instead of 10W30?
Between a 10W-30 and 10W-40, 10W30 motor oil would run smoother in colder climates while a 10W40 would be more effective in preventing engine wear and tear in warmer temperatures.
Is SAE 40 the same as 10W40?
The higher the number, the more viscous or thicker, the oil is at higher temperatures. This means that at 100oC, 10W30 engine oil has the viscosity of an SAE 30 single grade oil, and 10W40 oil has SAE 40 viscosity. 10W40 oil has a higher viscosity, retaining more thickness than 10W30 as the temperature rises.
Does 10W40 hurt 10W30 engine?
If you were to put 10W40 in an engine designed for 10W30, the “thicker” oil would lead to friction in the engine and an increased load on the oil pump. The car would have to do more work to get the oil around the engine block.
Is it OK to use car oil in a lawn mower?
The oil you use for your car's engine is the same one you can use for your lawn mower. However, make sure that your motor oil is of high quality before using it in a lawn mower engine, which is comparably smaller and less hardy. The quickest way to shorten the life of your lawn mower is to use low-quality engine oil.
Can you use 10w40 instead of SAE 30?
However, in general, I probably wouldn't recommend using 10w40 instead of SAE 30 in your lawn mower. Most lawn mower engines are designed to use oil with a viscosity rating of 30. Because 10w40 has a higher viscosity, your engine might not be able to lubricate itself as easily.
What is 10W-40 oil for?
Higher viscosity oil such as a 10W-40 can be useful for older engines burning or leaking oil. We offer Mobil™ 10W-40 high viscosity motor oils for use in vehicles with more than 75,000 miles, and a synthetic blend oil when cost is a consideration.
What is the difference between 10W30 and 10W40 engine oil?
The difference between 10W-30 and a 10W-40 is the high temperature viscosity. Obviously, a 10W-40 is thicker than a 10W-30 at high temperature.
Which is more fuel efficient 10W30 or 10W40 engine oil?
Technically, a lighter weight oil will provide better gas mileage as it's lower viscosity makes it easier to move through the oil system. However, the difference between 10W30 and 10W40 will be indistinguishable.
What happens if you use 10W40 instead of 5w30?
Your vehicle does not use 5W-30 oil. The recommended oil viscosity for your vehicle, according to Kia documentation, is 10W-40. If you drive the vehicle in exceptionally cold weather, well below 32 degrees, you can use 5W-30 oil but even 10W-40 is still perfectly OK to use if outdoor temperatures are below freezing.
Is 4 stroke lawnmower oil the same as car oil?
Four-Cycle Motors They use the same oil as automobiles, but owners should check manuals because these small engines are sensitive to additives and alternatives. Some will specify that detergent additive or synthetic oil be used.
Do lawn mowers need special oil?
When choosing lawn mower oil, use a high-quality detergent oil classified as "For Service SF, SG, SH, SJ" or higher. Do not use special additives. Synthetic oils are an acceptable oil at all temperatures. The use of synthetic oil does not alter required oil change intervals.
What is the best oil to use in a lawn mower?
Any two-stroke motor oil made for air-cooled engines, such those in chainsaws, water pumps and weed eaters, will work perfectly in your two-stroke lawn mower engine. SAE 30 Oil: Engine oil best suited for warmer temperatures. SAE 5w-30 Synthetic Oil: Synthetic mower oil good for warm and cold weather use.
Can I use 10w40 oil in a lawnmower?
Any electrical machines, vehicles, or motors are runner by oils. For different sorts of engines, the oil requirements also vary. That is to say, the engine that runs a car will generally look for a different kind of oil than the engine which runs outdoor equipment like lawnmowers.
Can I use 10W40 instead of 5W30 in my lawnmower?
You can use 10w40 in your lawnmower, but that doesn’t mean you can put it instead of 5w30 oil.
Is 10W40 the same as SAE 30?
No! 10w40 and SAE 30 are two different oils with different kinds of engine requirements. But, this is not applicable everytime as both the oil can sometimes be used in the same engine without any problem.
Is it OK to use 10W40 instead of 10W30?
To consider this matter, you first need to rely upon some factors. Then you can decide whether 10w40 over 10w30 is OK for your lawnmower or not.
What is the best oil to use in a lawnmower?

What is SAE 10W30?
SAE 10W30 is an oil that has SAE 10W viscosity (thickness) at low temperatures, and SAE 30 viscosity at high temperatures. The W stands for ‘Winter’. Note that these viscosities are relative, and standardised numbers and no absolutes, the oil doesn’t get thicker when it’s hot, it gets thinner.
What is a side valve lawn mower?
Most lawn mowers are side valve four stroke, very simple designs that make limited power but are very reliable and run at limited speed. I have a 1951 Willys CJ3A jeep that has a similair engine but larger and designed for SAE 30 in warm climates. In winter you would change to a lighter grade.
Can I use 10W-40 oil in a lawn mower?
The same motor oil types used in cars, such as 10W-30 or 10W-40, can often be used in a lawn mower. Sure, specs on my Kawasaki liquid cooled engine list SAE 30 weight as well as 10w30 and 10w40. Most small engines are stated to possibly use more of a multi weight oil than a single weight.
Can you use wet lubricant on a drivetrain?
Using a wet lubricant will require a little more maintenance however, as its sticky nature tends to attract grime. Left unattended the can turn the lube into a lapping paste that makes quick work of your drivetrain. Regular degreasing and lubrication is essential if you opt to use a wet lubricant. Ceramic Lubricant.
Is a 10W40 better than a 10W30?
Many four stroke mowers these days recommend a 10w30 rather than a straight 30, so a 10w40 would probably work OK too. It will remain just a little more viscose when hot than a 10w30, but the difference is small. You might even find it a little easier to pull start on a cold day with a 10w30 or 10w40, since the “10” viscosity indicates it’s thinner ...
What grade of oil should I use for my lawn mower?
We’ll also compare them to the most common lawn mower oil grade, SAE 30, since most small engines require a minimum oil weight of 30.
Why do lawn mowers need oil?
Just like any other engine, lawn mowers require oil to keep their parts lubricated, especially since they tend to run hotter than bigger engines. You might be thinking about using some leftover car oil for your mower to save time and money. Before you go and do that, it’s important to know what kind of oil you’re putting into your mower, ...
What is 5W20 oil?
5w20. This is thinner oil designed more for newer cars, cold climates, and for better fuel economy. Generally, I don’t recommend this one for lawn mowers since it runs a bit too thin. The maximum viscosity it can reach is 20, too thin for most small engines.
What is the formula for car oil?
Thus, car motor oil is often labeled with a formula like 10w30 or 15w40.
Why is small engine oil single grade?
Small engine oil is usually single grade because small engines run much hotter and thus need the oil to remain thick to keep the engine lubricated. Thus, a lot of small engine oil will labelled SAE 30 or 40. Most car engine oil nowadays is multi-grade, since not only do big engines not run as hot as small engines, ...
Is 5W20 oil good for lawn mowers?
Popular in most passenger cars. This oil is more useable in lawn mowers than 5w20, since it reaches the ideal weight of 30 at operating temperature, but keep in mind it can still become too thin if especially hot or especially cold. Check your manual first.
Can you put 2 cycle oil in a lawn mower?
Only if your lawn mower has a two-cycle engine. Remember that two-cycle engines have one cap that a mixture of both fuel and oil goes into, so if you pour premixed two-cycle oil into your four-cycle engine’s oil cap, you’ll be adding gas into your oil tank, which could completely ruin the engine.
What temperature should I use for a lawn mower?
All the lawnmower companies have the same recommendation; 30 unless you need to start in cold weather, and then 10w-30. But 10w-30 will be consumed over 80 degrees. Why not 10w-40.
Why is 30W needed?
the reason 30W is specified is that the lawnmower runs at a constant RPM, in a pretty static environment and probably runs pretty hot. There isn't a cold startup phase like a liquid cooled engine running in the winter. So you just don't need a low low viscosity startup.
Why use lower viscosity oil?
The main reason behind the use of lower viscosity oils today is due to flowability causes less friction to moment lowering emissions. Click to expand... True. But, if it's an older engine, the toerances aren't as tight, and 5w30 will tend to be way too thin.
Can you use 5W30 in a push mower?
You don't want to use 5w30 in a push mower, it'll just burn up, because it's so thin. Straight 30w will be thick as honey when it's really cold (that's why it isn't reccommended for winter use), but thin right down at operating temp. The advantage, as you saw, is that it'll take a lot more heat.
Is 10W40 oil thick?
10w40 is too thick at temp to lubricate properly and help with heat dispersion. Air-cooled engines are picky like that. I always use 10w30 in the winter in all my stuff, (but my car) and straight 30w B&S oil in the summer. When the temp doesn't get below 60 at night, you don't see a lot of advantages to multi-vis.
Does Briggs and Stratton use synthetic oil?
Briggs and Stratton has approved the use of 5w30 synthetic oil in all of there engines. Winter or Summer for all temperature ranges. The 5w30 synthetic wasn't approved by Briggs until a couple of years ago or so and is retroactive to older engines.
Is 5W30 synthetic or synthetic?
ILENGINE said: briggs is now recommending 5w30 full synthetic in their engines. Other manufacturers use 10w30 due to some mechanical requirements (hydraulic valve lifters in Kohler Command) which will overpump and cause valves not to close if 30w is used below 50 degrees.
