Ok Im in an auto tech class at school and we are able to bring in our personal vehicles any time and work on them. My questions are how good is generic AC delco motor oil? Cause thats whats in the shop or am i better off going out and purchasing my own oil if so what kind. My car has 49,280 miles on it. Also I was told by one of the guys with a v8 stang that the conoco gas accross the freeway was noticibly better then the shell and chevron gas closer to home. He claims it lasts longer so less filling up and that he can feel extra power with the fuel. He runs mid grade so im just curious if hes right or am i better off getting shell closer to home.

All sho no go...

AC Delco is made by Mobil...good oil. I have not used Conoco fuel, but I do know that I can tell differences in the Volvo at certain stations. It hates BP, and seems to enjoy ethanol free Shell premium, and midgrade Cenex ethanol free fuel.
