Hey guys,

I'm tagging along the other post about gear box oil.....any recommendations for the best engine oil?.... 83 911 SC coupe. The car has used nothing but Torco TR-1 20W 50 Race formula for most of its life...by the original owner. I was thinking of using Swepco 20w 50 instead.

Went with Penn Grade 20w 50

For non-synthetic oils, we use & recommend Brad-Penn racing oils; 15w-40 or 20w-50 for hot weather. Valvoline VR1 is OK, too.
