I was at Wallmart tonight and I was amazed at the selection of quality oil they have there. Anyhow would you oil guru's please rate the following oils? I forgot to jot down the price of the Delo 400, sorry. I tell you the Super Tech sounds like a hell of a bargain.
Delo 400 15W40 API CI-4, CH-4 etc.
Delvac 1300 Super 15W40 API CI-4,CH-4 $5.88 gal
Super Tech 15W40 API CI-4, CH-4 $1.17 qt
Rotella T 15W40 API CI-4, CH-4 $6.27 gal
Rotella T Synthetic 15W40 API,CI-4,CH-4$12.84 gal
