What is the difference between 520 and 1030 oil grade?

Question

Is it ok to use 1030 oil on my 2006 ford f-150 truck?

Answer 1

The different oil grades relate to which environment they are to be used in (extreme heat or cold for example).
You should use what Ford recommend for your engine in your particular usual environment.

Answer 2

The temp range that they will work in. The 5-20 will be for cooler weather and the 10-30 will be for warmer climates.

I recommend using the grade of oil that the manufacturer suggests.

Answer 3

In the winter months stick with Fords recommendation...in the hotter months it will probably be ok to run a heavier oil...the difference is in the tolerances that todays engines are built with and require a lighter oil for quicker lubrication and better
lubricity on a tighter tolerance....

Answer 4

The first number is the oil thickness when cold and the second number is after it warms up. So 5w-20 will flow better in colder climates and 10w-30 is better in warmer climates. But I would stay with the Manufacturers recommendations to be safe.

Answer 5

No, Stick with the 5w20. Your engine is designed for it. If you use a heavier weight oil, it cannot get oil through the small passages and will cause extra wear and possible engine damage.

Answer 6

5w20 flows faster one startup and provides better lubrication when the engine is cold. It also provides better gas mileage. That's why most car manufacturers recommend it. Don't mess with it. Use what the manufacturer recommends.
