I'm changing to synthetics, I was using Pennzoil race oil 20w50 as recommended by my engine builder in 1981, GM gear oil in trans & rear. Changing to: Engine - Mobil 1 10w30, Trans - Redline MTL or Mobil 1, Rear, Mobil 1 with GM add. Unless enough of you disagree with my choices. [img]smile.gif[/img]
My main question is, is it better to change oil after or before running the car? I usually do it after running a little to warm it up but I'm thinking in this case I'm better off changing cold since most of the oil will be at the bottom because it's been sitting a couple days now which will give less mix of the 2 types of oil.
I have a 1970-1/2 LT-1 350 s/b from factory new in 1981 has around 15,000 miles on it.
Muncie M21 4spd trans.
12 bolt posi rear with Zoom 456 gears.
1967 Camaro coupe Deluxe interior LT-1 350 w/ 4spd. M-21 trans and 12 bolt rear.
