Welcome to Just Commodores, a site specifically designed for all people who share the same passion as yourself.
From what I've read in the handbook that's supplied with the car, you can supply any consumable (oil, filters, plugs, etc, etc) to the dealer...Did u use the same brand of oil prior to getting ur service? im almost up 4 my sched serv 2 and was gonna ask the mechs wat brand and quality oil they used because if it wasnt a good one i was going to ask to supply my own,is this allowable or only they use wat they want?
