Sorry Wrenchtech, I don't totally agree. I would have before but I have had a few customers change over and has actually seems to have helped the engine. They said that the fuel milage has gone up not much only about 1 - 3 miles but now days thats good. These customers have kept up the regular maintenance schedule since they bought the vehicles and haven't had any major engine problems. And it has been about a year since they changed over. Oh, and one of them had a very light tapping and didn't want to do anything till it got worse but has since stopped since using synthetic oil. Wouldn't believe it if hadn't see it for myself.
