What happens if 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. Hence, a car will start with fewer cranks when holding oil of a lower winter weight. 10W40 oil will perform cold starts better than 15W40 oil.

What is 15W 40 engine 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.

Which engine oil is best for Ford Fiesta?

The best engine oil for the Ford Fiesta is 10W40 semi-synthetic grade oil.

Is it OK to mix 10w40 with 15w40?

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.

Can you mix 10w40 with 15w40 oil?

No, it is not ok to mix 2 different oils. Both oils will have different consistency, different viscosity else the oil manufacturing company would make only 1 grade of oil for all purposes. It will damage the engine to an extent that you’ll have to junk the engine completely. Its like mixing tea and milkshake.

Is 15W40 synthetic oil?

Mobil Delvac™ Extreme 15W-40 is a synthetic, high-performance diesel engine oil that helps extend engine life while providing long drain capability for modern diesel engines operating in extreme conditions.

What type of oil is 15W40?

15W-40 is a very common viscosity grade for diesel engine oil. GTX Diesel is a 15W-40 diesel engine oil formulated to help extend engine life.

Is it OK to mix 10w40 with 15W40?

Can you mix 10w40 with 15W40 oil?

What is 15w40 oil used for?

15W40 oil changes less with change in temperature. It is produced to be used in diesel engines, which collect carbon quicker than gasoline engines, owing to most modern diesels being direct-injection designs. Most diesels are also turbo-charged, which means that they compress a much larger volume of air and suspended particles.

What is the difference between 10W40 and 15w40 PCO oil?

…a 15W-40 HDEO (heavy duty engine oil) is more shear resistant than a typical 10W-40 PCO (passenger car oil) because the viscosity spread is less (there is less need for additives to extend/maintain the viscosity range).

Can I use 10W40 instead of 15w40 in my Mercedes?

10W40 however is never marked as meeting mercedes spec’s on castrol bottles as the 15W40 is. So I find it strange that while 10W40 can be used, why its not recommended. Here in canada 10W40 is alot more common and availble in more brands then 15W40, however the 15W40 is much cheaper.

What is the difference between 5W and 10W lubricants?

On the other hand, you may use a 5W viscosity grade where a 10W or 15W is recommended to provide faster lubrication to engine components during start-up. However, there are some drawbacks to consider. For instance, since a lighter base stock is used in the 5W formula, the lubricant may have more evaporation than a 10W or 15W.
