Hey Everyone, Not going to start a which oil thread, etc. But lets say you're using oil which is priced a bit high. Dealer will only charge $10 to do the complete OC, etc - if I bring own filter and oil. In order for them not to just take the oil I bring, and then use just some other oil - is requesting the empty oil containers back one way I'm guaranteed the oil was put in my vehicle? Am I a bit paranoid thinking that whoever is changing it, might just bring his own vehicle around it, change it/have a laugh with the other techs and then give me the empties, lol.
