Hey! Does a high volume oil pump have an adverse affect on the MPG's, as opposed to a stock oil pump???!

i would say yes to the high vol oil pump.. a stock pump is fine for the street

It's More to do with pressure. the high volume pumps tent to build more pressure and building pressure takes power so some parasitic loss! all ads up.
But for safety at RPM a like a high volume pump with and light or adjustable releif spring so you can set your max pressure at say 65 not 110 but it still has the volume when called for.

this is with 1/2 15/40 and 1/2 5W 50 motor was cool

this was on enital start up this summer went to 68 I think dead cold.
Course the alt quit just as I mentioned it wireing issue took ot the regulator all fixed now.

it has to do with volume as well you can't build pressure if your bearings are sloppy and leaking all over. if you have tight bearings then no need for a high volume pump. hydraulic horespower is calculated by hhp=pressure*flow/constant.

therefore both components are equally important when figuring parasitic loss. if you don't need a high volume pump don't use it.
