I'm not a car guy, but I do know (having learned the hard way) that changing your oil only every year and a half is an excellent way to need a new car. In order to avoid replacing my current one, and owing to my local mechanic's recent changeover to "weekdays only". . . I took my car to Valvoline Instant Oil Change to have. . . my oil changed.
They changed my oil. BUT. . . they also topped off fluids, explained the process, changed my air filter, checked my lights and much much more. . . in about fifteen minutes.
I didn't call ahead. I didn't sit in the "waiting room" leafing through old Cabella's catalogs and 2010 Hot Rod magazines. I just sat in my car, drove up to the garage doors. . . and let the magic happen.
And it is magic to me. . . cause I'm not a car guy. If you're not a car guy either. . . good place to know.
