I currently use Mobil 1 10w30 in my LT1 Z28 with cam, 3500 stall, 3.73s, blah blah blah.... It just seems so "thin" and it seeps out of a few places. (one or two drips a week) I change the oil in the car very often just as something to do or after beating on it for awhile. It ends up usually being about 2000 miles. I dont care if the oil is dino, synth blend, or full synth. I just want something that I dont want to pay for Redline. I would like to try Schaeffers, but I am worried about shipping being a lot. What oil would you guys recommend?
