Hey dudes,
I got a free oil change from my local Ford dealer yesterday, and I just realized that the guy never asked me if I wanted synthetic or not. I have always used synthetic oil and was told a long time ago that once you put synthetic oil in an engine, you can't go back to conventional because it is bad for the engine, but I don't remember why.
Is this true???
