    Default 2010 chevy silverado crew, 5.3, 3.07, AFM, 6 Speed

    Rough idle at a stop light,sign. 25000 mile. 3000 miles after last oil change was a quart low. normally i do my own oil changes but i bought the truck with 16500 miles on it and got a couple free oil changes when i bought it. no oil drips, i always park in the same spots at work and home. gonna start changing my own oil again and gonna go with mobile one 5w30. all my other cars and trucks have had synthetic oil so i figure gotta change this one over too. any guess about the rought idle? or if synthetic is not a good idea? Just would like help or ideads. thanks.

    Welcome to the Club!! You may want to post your question on the Tech Q&A portion of this forum. Not sure about the rough idle, but I do use synthetic oil.
