Can I use 10W 40 in my Craftsman lawn mower?

You absolutely can! It’s usually a better idea to go with SAE 30 or the lawn mower oil recommended by the lawn mower’s manufacturer, but it more than likely won’t be an issue if you use 10W 40 oil instead.

Is 10W40 the same as SAE 30?

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. Using the correct viscosity oil eases starting, reduces friction, and slows wear.

Can you use 10W40 instead of 10W30?

This is the reason your location is so important in selecting which oil to use. 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.

When should I use 10w40 oil?

10w40 is better suited for hot weather or heavy loads. When you expect your vehicle’s operating temperature to be higher than most casual driving cars, using 10w40 is recommended. The higher viscosity of 10w40 at high temperatures reduces wear and tear when putting more pressure on your vehicle’s engine.

What can be used in place of SAE 30 oil?

After you look at the API specifications you need to check the viscosities, in this case you need to use 5w-30 or 10w-30 oil as a substitute for the SAE 30. You need to keep the second number the same as your straight SAE 30, this is the viscosity of the oil at operating temperature.

What is the best engine oil for hot weather?

What kind of oil do you use in a craftsman riding lawn mower?

What kind of oil do you use in a Craftsman riding lawn mower? The oil must conform to API service classification SF, SG or SH. When operating at air temperatures above 32 degrees Fahrenheit, use SAE 30 motor oil. For air temperatures below 32 degrees Fahrenheit, use multi-viscosity 5W-30 or 10W-30 motor oils.

When to use 10W30 vs.10w40 on a lawn mower?

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.

Why is the 10W40 engine not recomended?

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 kind of oil does a Briggs and Stratton lawn mower use?

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. 1

Why do you need motor oil in a lawn mower?

The motor oil acts as lubricants for the engine. And like fuel, motor oil is also very vital for the smooth functioning of a vehicle or lawn-mower. When you turn on a cold engine, for instance, the thinner motor oil flows or travels to the top of the engine with high speed before it starts coming to its original level.
