Lifetime Maxcare warranty is good for people that use the dealership service department for Everything including oil changes. Guy on a different forum had is engine failure blamed on him for using a aftermarket oil filter, Maxcare denied his claim. Another guy on this forum had his tranny blow up and they blamed him because he serviced his own transmission, Maxcare denied his claim. If they have Any excuse to deny your claim they will. Good short term business plan.
Guy like me that enjoy maintaining a vehicle it's bitter sweet. I like having the option of what oil I use and having the option of using my favorite fluids. This is not an option with Maxcare.
