There is chain service outfit here that offers 14.99 oil changes in bulk mailed sale papers. They offer a variety of other service such as brakes, shocks, cv joint replacement etc and I know this is A gimmick to get people in place and hope they can be sold other services. They say in their ads that they use house oil in their changes, they offer 5w 30 0il and their oil is the Shell brand. I have heard countless arguments about such and been told one major brand of oil is as good as another. Whats you guys thought on the Shell brand. Since I once operated a garage friends ask me but I don,t know the answer. I personally never thought there was much different in premium brands.
