Sorry guys but a lot of you have it all wrong wal-mart does good oil changes cheap and no they don't 1 qt good stuff and 4 qts bad they use all 5 qts of the oil you pick out wal-mart pays 12 $ for the 5 qt mobil becaus they order 1000's of quarts of it everyday they get a monster discount because all of the stores they have order the same oil and I used to be a lube tech and the employees that worked there did great jobs and the entire time I worked there which was a year they have only had 1 claim filed against them.
