Maybe for future refference???
I took my vehicle down to one of those quick Lube places, not sure wich one. I had the oil changed there once before a trip. Now my vehicle is in their system. So every time after I go 4x4ing; I just stop by quick lube on the way home to have them check my fluid levels. All of them for free. Radiator, Diffs, trans, oil and washer fluid. They even top them off without charging me. So I continue to go there to get that service, and have even returned for oil changes.
