Hi List, I drive my Delorean almost every day, and I wanted to know what is the best weight of engine oil to use. Iam running 20W-50 Castrol right now, should I run a 10W-40,10W-30 or is the 20W-50 alright? I live in lower Alabama and my car has about 150,000 miles and is still running strong.Iam not sure what the owner before me ran in the car. I am also running a lucas oil additive. Thanks, Casey VIN# 3270 __________________________________ Do you Yahoo!? New Yahoo! Photos - easier uploading and sharing. http://photos.yahoo.com/
