hi, what is the general consensus on that statement about a pure street car, like mine not needing 20w50. as I have been using it for years?
vr1 racing oil 20w50 for a pure street car. is it unnecessary?
Car is an ex race car , 1987 944. at warm up oil pressure is 3.5 - 4.5
Im just curious what everyone in the community says. as I have never heard this.
