Quick Answer: Can I Use 15w50 Instead Of 10w40?

Which is better 10w40 or 15w50?

(test temperature used to simulate the temperature of a running automobile engine) Similarly, the 10W40 has a viscosity index cold rating of 10 and a hot rating of 40.

The 15W50 has numbers higher than the 10W40, therefore the 15W50 is thicker both at ambient winter test and engine operating temperatures..

Will the wrong oil damage my engine?

You might notice a few oil spot in your garage or under your car because using the wrong oil can lead to leaks, or you might become aware of a burning smell while driving. If the oil isn’t working as it should engine parts might not be lubricated well enough and cause friction, which can burn the oil.

Is high mileage oil thicker?

A: Yes. This is a practical method to improve oil pressure in an older, high-mileage engine. The slightly thicker oil film from the heavier base weight oil – 10W – can help protect worn engine bearings as well.

What happens if you mix 10w30 with 10w40?

You will be fine with that. They will mix right in with each other and no harm will be done. Even if you were to mix syn with conventional you’ll be fine. If you were to labratory test your oil it will read out as not a true 10w-30 but no harm will be done.

When should I use 10w40 oil?

Overall the 10W30 will be the more appropriate oil for cold weather and non-performing engines while 10W40 is perfect for warmer temperatures and older vehicles.

Can you mix 15w50 and 20w50?

But like I said it would be fine to interchange 20w50 with 15w50. You will find it easier to cold start. It depends on the vehicle you use.

Is 10w40 good for winter?

Yes, although they are both technically 10w oils, a 10w-40 is much thicker in cold conditions compared to a 10w-30.

What is 15w 40 oil used for?

ADVANTAGE 15W-40 HEAVY DUTY DIESEL ENGINE OIL can be used with complete success in over-the-road diesel trucks, off-highway diesel equipment, farm tractors, and passenger cars and light trucks with diesel, turbo-charged diesel engines, or gasoline engines and is backward compatible with previous API Oil Categories.

What oil is thicker 5w30 or 10w40?

A 10w-40 motor oil is a thicker oil at startup than a 5w-30 motor oil. Therefore, 10w-40 oil clings to the engine’s moving parts more than the lower viscosity 5w-30 oil.

Can I use 15w40 instead of 10w40?

A 10W40 oil will be thicker in the cold than 15W40 oil, but they will have the same viscosities at higher temperatures. The winter viscosity number dictates cold-start performance. … 10W40 oil will perform cold starts better than 15W40 oil.

Can you mix 15w50 with 10w40?

There is absolutely no harm in mixing different grades of engine oil! All motor oils are required to comply with international standards which include a compatibility test. This means that any branded engine oil will mix with the standard test oil in any proportions and the mixture will still perform as specified.

What is 10w40 oil good for?

Using the correct viscosity oil eases starting, reduces friction, and slows wear. For even more effective start-up protection, use a synthetic 10W-40 instead of a conventional 20W-50. The synthetic 10W-40 flows easily and still maintains enough viscosity to protect piston skirts and bearings when it gets hot.

Can I use 15w40 oil in my bike?

Sure. Any oil is better than no oil. One can combine any weight and type of motor since they’ll intermix so doesn’t hurt anything if one tops up a petroleum motor oil with a synthetic oil or use a combination of what’s on hand to fill the sump.

Can I put 10w40 in a 5w30 engine?

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.

What happens if I put 10w40 instead of 5w30?

If you use 10-w-40 instead of 5-w-30 specified by the manufacturer then the viscosity of 10-w-40 used by you will be higher and oil thicker than what is specified during winters. Similarly the oil viscosity will be higher and oil thicker than specified during summers.

Can I mix 20w50 with 10w40?

You can mix most oils and won’t see any problems.

Is 20w50 good for high mileage?

The viscosity level of engine oil 20W50 is geared toward racing engines, as opposed to high-mileage engines, that run extremely hot and need heavy load operation. … Since its viscosity is so great, it can drag down the functioning of the crankshaft, resulting in less horsepower.

What oil is thicker than 10w40?

The only difference between 10w30 and 10w40 oil is their thickness at engine operating (hot) temperatures. They will flow at the same rate during a cold startup since the starting viscosity is “10” for both formulations.

When should we change engine oil for Royal Enfield?

After how many kilometers engine oil should be changed in Royal Enfield Classic 350? According to the new norms, every 5,000 km or six months, whichever occurs earlier. The previous recommendation by the company was 3,000 km or 3 months.

Can I use 10w50 instead of 10w40?

The difference between 10w40 and 10w50 is how thin the oil gets when it’s hot, 10w50 oil won’t thin out as quickly as 10w40 when oil temperature goes up, but it also might be too thick during regular running in cold temperatures (I think you’ll be fine though).

Can I use 15w40 instead of 15w50?

What problem creates if I replace 15w40 oil with 15w50 oil? … The heavier oil will provide slightly more high temperature protection and the cold starting would be the same. Most (but not all) SAE 15W-50 oils will have better performance than most SAE 15W-40 oils.
