I've read a lot on this great site but am still confused about oils.
I went to Kragan's yesterday to look at the dino oils and found Shell, Chevron and Exxon (I think it was Exxon) retailing at $1,89/qt. Valvoline, Pennzoil and Castrol GTX at$2.79/qt. Is there really any differences between them? Kragen currently has both Chevron and Formula shell on sale at 49 cents/qt. with mail-in rebate and Pep Boys has Exxon Superflow at 79 cents with the rebate which make those oils very attractive but I'm still not sure about their quality compared to the more expensive oils.
My cars are: '94 Saturn 1.9 w/155,000 miles, '98 Dodge Dakota 2.5 (4 cyl)w/98,000 miles and a Ford Contour 2.0 w/100,000 miles. I live/drive in Southern Calif. and I have to admit that I don't do my OCI's as often as I should. Would appreciate any advice/help you can give me.
