I hear all this talk about hpop ans Big oil and I have no idea what any of it is. If someone could educate me on this stuff I would greatly appriciate it. Oh and I also saw in a post about injectors using more oil than others. Why do injectors use oil? Sorry for all the questions...
injector and oil questions
1 - 5 of 5 Posts
Powerstrokes have a hydraulic injection system. The crankcase oil is run through a high pressure oil pump aka "HPOP" and into a piston in the head of the injector. The oil compresses the piston, which compresses the fuel in the lower part of the injector and pushes it out the nozzle. Of course, I'm being very general here and others will probably jump in and give more accurate details.
Big Oil set ups use 2 high pressure oil pumps to feed larger aftermarket injectors. Larger injectors deliver more fuel, but require a larger volume of crankcase oil to maintain the necessary pressures. They don't "use" oil in the same sense a worn out motor uses oil. They just need a bigger supply than factory injectors.

Nice "Big Picture" explanation.

A "big oil" system will also increase performance of stock injectors. I've got a dual hpos system in my truck running the stock injectors and it improved my fuel mileage, widened my powerband, and well, just made the truck more fun to drive. /ubbthreads/images/graemlins/grin.gif
