I've also been told by a friend whose career has been in the oil industry that there are only 3 oils that are truly synthetic--Mobil, Amsoil and Redline. All others are supposed to derivatives of pertroleum products. also have a '04 Viper (78,000 miles) with synthetic as well as a Hyundai Azera (93,000 miles) both of which have always had synthetic and never used a drop of oil.
They've made a believer out of me

I use 15/50 Mobil 1 in my race car cause I turn it 7,000rpms and run an oil temp from 230 to 260 while racing depending on the outside air temp....Synthetic oils are good for 300 degrees whereas dino oil is good for about 240 degrees...........

With that said, everything else I own gets 15/40 Shell Rotella T....that would be my 05 F-250 diesel, my wifes Taurus, daughters Altima,my 65 Fastback, and my Toyota company car as well as my lawn mower and garden tiller.........This company car only has 110,000 miles as of today, last one had 431,614 miles on when it was totaled in a wreck, the 2 cars before that one each had 250,000 miles on them without any problems, in fact, none of these vehicles ever so much as had a valve cover off since new!!!!!!!!!!!!!!!!!! Dino oil works and has been working for more than 100 years now...........
