i was traveling through havre. took my car to walmart to get oil changed. when it was complete i asked if anything needed addressing, the clerk told me a new oil plus had been placed and good to go. i did not get a reciept so i went back in to get one and was then given a folded up piece of paper. later i looked at the paper and was surprised to find out my air filter, wipers and headlights did not pass their testing. also, it indicated i refused a transfer case test, which was never offered. and not a big deal but the form also indicated that they washed the windows and vacuumed which also never happened. took my vehicle to another lube place as i wasnt sure if the oil was even changed.
