Can I use 10W-30 instead of 15W40?

Can I use 10W-30 instead of 15W40?

Since 10W-30 is thinner than 15W-40, its film strength can be weaker and it can be more prone to oxidation. Therefore, high quality additives are needed to compensate for those weaknesses in order for 10W-30 to protect as well and last as long as 15W-40.

When should I use 15W40 oil?

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 oil is better 10W30 or 15w40?

Because 10W-30 is thinner than 15W-40 oil, its film strength can be weaker and it can be more prone to oxidation. High quality 10W-30 oils can perform as well, and better than industry-standard 15W-40 oils.

What is 15W-30 oil used for?

The new Delo 400 SD SAE 15W-30 is a CJ-4 engine oil blend specifically formulated for what Jim Gambill, Delo brand manager for Chevron, called “severe duty” cycles characterized in trucking by higher engine revving due to stop-and-go driving on congested roadways as well as engine idling restrictions.

Can I mix 10W40 with 15W40?

If both have the same specs bar the 10W then it wont hurt 10W means at 10 degrees and 15W 15 degrees outside temperature, so adding 10w wouldn’t do much in temperature wise as long as both are semi or so on with the same API specs.

Can I mix 5w20 with 15W40?

There is no problem with mixing oils, either mixing viscosities or brands, or synthetics with mineral. It is done all the time.

What’s the difference between 10W-40 and 10W 50 oil?

In general, a 10w-40 will have lower viscosity at running temp. That means it will go into and squeeze out of bearing and piston clearances faster than 10w-50 for the same load. In general, big twins have more piston clearance vs comparable 4 cylinder bikes that might run 10-40.
