Ask your friends, neighbors, coworkers for a referral to a friendly local independent shop. Oil changes are routine maintenance and there's no need to go to the dealer for such.
We keep the 0W20 in stock for the newer cars we service, and a routine oil change/tire rotation is $54.95.
In the long run, say you change your oil 3 times per year. And lets say the synthetic oil change costs $25 more than conventional oil. You're talking $75/year to keep your new car running right.
