Quick Answer: What Oil Is Thicker Than 5w40?

Which oil is thicker 5w40 or 10w40?

10w40 is thicker than 5w40, ONLY when cold.

At operating temperature it is exactly the same.

Multi-viscosity oils with a lower W number are specifically designed to flow better, and thus lubricate better, at very low temperatures.

Will 10w40 hurt a 5w40 engine?

The main difference between the two oil types is that one is thinner than the other. The 5W40 is thinner than the 10W40 at lower temperatures.
