oil bypass system
 

I havent seen much talk around here about a oil bypass system. It filters out oil down to 2 microns and makes the oil able to last virtually forever. The use them on trucks all the time. I have one on my wifes yaris and havent changed the oil in 15000 miles and it still looks clean. Look into amsoil website.

Perhaps there's not much talk about it because the stock oiling system, maintained with el cheapo Fram filters and Wal Mart oil, and changed at NORMAL duty intervals (if not even less frequently) will allow engines to survive to 300,000 miles and beyond. In many cases, the rest of the car is shot or the owner is sick to death of driving it before the 300,000 mile mark arrives.

I suggest removing the oil to increase MPG, the oil pump robs a lot of engine power. If you use those additives you don't need an oil pump, they show them on TV were they drain out the oil, and the engine still runs great.
This should help MPG a lot.

Hell, my '88 Escort has never had a by-pass system on it, I'm currently using 10K mile oil change interval using conventional oil and have been for about the last 40K miles, the car has 514K miles on the original engine with no rebuilds and still running. Engine still holds about 40-50 PSI oil pressure on a warm engine at 50-55 MPH on the highway and about 20-25 PSI at idle. Now tell me how a by-pass system will give me better service.

:eek:

Sarcasm I hope...

As far as reducing horsepower requirements to get more mpg it would be better to use a dry sump with crank scrapers and or windage trays, as these would reduce the amount of HP needed for the crank to rotate.

a crank scraper is a good idea, but it wouldn't be needed if you drained the oil from the crankcase.

if you do use oil, using the thin 0wt oil helps, you can add some water to it to thin it out a little more.

as i do dyno tuning when i get a mod done.
the guys at my dyno shop are into there v8's
they have a car with dry sump, lumpy cam, and an ecu flash
they said the dry sump only gave them about 14kw.

btw there car makes about 470ishkw so yeah

Dry sump oil pumps have more drain on HP then wet sump oil pump .

There is a vid of big block wet sump on dyno that they remove 1 qt and it gained noticeable amount of hp. this was large wet sump i believe 6qt ,so they ran 5 qt .

0wt? yes. water? no, that's just asking for problems
