[QUOTE="paradisepwoffrd, post: 751706, member: 4561"] You have to think about the oiling system like an other hydraulic/fluid system. The pump is rated for volume and pressure. Pressure is the resistance to flow. In an engine/oil system, it indicates the clearances in the oil journals. The numbers are also based on the pump that you are using. A higher pressure pump means that it can overcome a higher head pressure in the system, or it can flow more oil as the clearances tighten up. A high flow oil pump can blow past seals & PCVs too. Jake is correct that a high flow pump will suck the pan dry faster. My opinion is, a lower volume pump is a partial fix, but the real fix is a better oil pan/containment system. Oil also acts as a coolant in your engine, arguably more effectively than the cooling system. Just like coolant, the more you can cycle it through the hot zones, the longer the fluid will last and the more heat it will remove. The longer the oil stays in the hot zones, the faster it will heat soak and break down. Increasing capacity will help with this also. [/QUOTE]
