why you say that ginge?

should do opposite as it reduces oil drag and therefore increases power.

race cars run a little oil as they can get away with for that reason.

It wont...

less oil will give higher oil temp so thinner oil.

less oil = less drag.

steve just what ive noticed, not saying its the way

oh race engines and road engines aint the same thing

im talking about my fuel economy went to 12mpg, i looked at a few things and found nothing,, checked the oil and it was a little low

now im back to 15mpg hence me posting

maybe its placebo

formula 1 run dry sump engines so friction loss due to oil "slurpage" (cant think of a better word)is not a problem. You'll probly find the loss of power is due to lack of oil round the rings resulting in lower compression. I am pissed so reserve the right to delete post when sobre...
