I always get my regular Car Repair shop to change the oil so they can look for potential problems. Plus, they have an incentive to do it right otherwise they miss out on future car repair business. If you look hard enough, you might be able to find a car repair shop that is reputable and competent and, most importantly, business savvy enough to match the small oil change outlets cuz they can hope to earn future business in other areas. If they are one or two dollars over I still think it's worth it; especially, if the car repair shop guys stop a problem before it causes a breakdown.
