Wanted to get some opinions from the board regarding Valvoline VR1 20W-50 vs. Brad Penn 20W-50 Racing Semi-Synthetic.
I'm using the Valvoline VR1 in my '89 Porsche Carrera which has a 3.2L air-cooled engine and 15,300 miles. For those who don't know...it has a 12+ quart oil capacity.
The Brad Penn has my interest for my next OC as it is a synthetic blend and appears to have higher levels of ZDDP that is helpful on these older engines.
Open to anyone's opinions.
