How much oil does a CAT 3126 take?
Caterpillar’s Document LEHT9288-03 (8-04) states that for the 3126/3126B/3126E/C7 engines with a shallow pan, 22 quarts of oil are required.
What’s the difference between 40 and 50 weight oil?
Each number in an oil weight designation covers a RANGE of actual viscosities. Both 40-weight and 50-weight oils COULD be the same viscosity (17 centistokes at 100°C). But in general the 20W-50 weight oil will remain a little more viscous at 100°C than the straight 40-weight will.
Is it possible to have more than one W grade oil?
Since each W grade oil is defined by a maximum viscosity and a maximum border-line pumping temperature, it is possible for an oil to satisfy the needs of more than one W grade. A multi-graded oil is labeled with only the lowest W graded satisfied.
Which is the best oil for a 440?
In the winter 10W-30 might be better. I’ve been using Valvoline VR-1 20W-50 Racing oil for years in my 440, but then I’m not driving the car in the dead of winter. It’s all pick your own poison stuff. For a 318, I’d look at straight 30 weight Valvoline VR-1, but that’s just me.
When does it make sense to use straight weight oil?
When does it make sense to use straight weight oil (SAE30) versus a multigrade oil (5W-30)? Straight weight oil is never recommended for use in a system that requires a multi-viscosity oil. Straight weight oils are generally recommended for smaller engines or older vehicles that were made before multi-viscosity oils were produced.
What kind of oil should I use for a 10W engine?
These oils were straight grade oils. A 10W flows well in cold weather, to protect the engine at start up, but it’s is too thin for use in the summer. A 30 grade oil, thick enough to protect in the heat, was recommended for summer use. Then, multi-grade oils were formulated.

What happens when you use a heavier grade of oil?
Using a heavier grade than recommended may cause decrease in fuel economy, higher engine loads and eventually shortened engine life. Using a lighter grade than recommended may result in excessive mechanical wear and reduced engine life.
