Yes, in my opinion all you are accomplishing is a few wasted horsepower and lower engine effenciency. I would start by getting back to a more normal weight oil. If you commonly drive in temps that are above 90F then use 10W-40. If you seldom see anything warmer than 80F use 10W-30. High pressures translate exactly into more power consumed in pumping the oil, and this is power that ends up as heat in your oil instead of moving you down the road.
