Wet Sump & Dry Sump

In this article, I’ll be discussing two different types of oiling systems: wet sump and dry sump. What are they? What do they do? Which one is best for me?

Let's start with the wet sump. What does it mean to have a wet sump? It means that we store the oil capacity in the bottom of the engine. This is how most stock engines operate. It works by having the oil sit in the bottom of the engine and when the engine is running, the oil pump picks up that oil and pumps it to where it is needed. The oil, then, runs out of the different areas it was pumped to and gravity feeds it back into the bottom.
