Question on the use of "racing" oils on the street. I understand they do not have the detergent load-up of a "street"
oil.
My engine seems to like Valvoline Racing 20W-50. And of course I need the cold start ability of a multi-grade
oil here in the UK.
The
oil gets changed every 2000 miles, engine always gets run long enough to heat through. Does this mean the "racing" oil is OK for my usage or is there still a potential problem?
Whaddya think?
