I do my own oil changes, keep the receipts and log the changes. I do mine every 6 months because that is what Dodge requires, since I never reach the mileage. When my warranty expires, I will do the oil changes as I see fit. Until then I keep on a strict schedule. Honestly though, it's not really a big deal to do the oil change twice a year, and gives me piece of mind knowing my oil is fresh and my Redeye is happy.
What are dealers charging for oil changes out of curiosity?
