I did just that for 3 years... My 2000 Audi S4 got free oil changes at the dealer but they used Bulk Dino oil back then. So..I let them change the oil. Went home and drained the oil into a clean pan. Put 0W-40 Mobil 1 or GC 0W-30 Syntec in the car and then used the "free" dealer oil in my Pickup. Got free oil and a "flush" on the Audi each time. I could have given them my oil... but would they remember or even bother with it. How would I ever know?
