Took my truck in a few weeks ago for an oil change. When I picked it up, I noted they had replaced the plug and seal. I also noticed they had filled it with 12 quarts of oil rather than the 11 it usually takes. They checked it out and said it was ok. When I got my truck home, I started noticing a small spot of oil in the driveway every morning. First leak I've ever had! I took it back and they put in another plug. When I got home, I found that the leak had gotten worse, rather than better. I'm scheduled to take it back tomorrow, but I don't have a lot of confidence they'll figure out the problem, so thought I'd ask you guys for some tips I can pass on to my dealer. Do you think the fact they overfilled with oil the first time has any relationship to my problem? Thanks for your help.
