i would have to agree with chevylover5, quaker sucks. its all gunky and just disgusting after the oil change. I use mobile 1 synthetic in my camaro, the engine was built with it so if i changed it would probably blow up lol. I also use Castrol gtx high mileage in my dd, cavalier 3.1, with over 140,000miles and i havent had a problem; i replace one of the quarts with lucas or duralube engine treatment to quiet the valves, damn 3.1's are noisy.
