I am actually not a big fan of synthetic oil. i recently had a chevy 2500 hd. i ran pennzoil for about 25,000 miles then switched to mobil 1 with all the talk about how much better it was. within 5000 miles my cam was bad, and a hydraulic cam should hardly ever go out. the tech guy told me that synthetic was so slick that in some cases it is harmful to an engine. i guess that is why they say not to break an engine in with synthetic oil. so i quit using it, i have used pennzoil for 15 years and never had a problem, so the sying goes if its not broke dont fix it.
