My buddy took his 08 Impala to the local Quick Lane which I have used myself before for a friend's car without issue. When he went to pay the bill, they wanted to charge him for an extra quart of oil because only 5 quarts are included in the standard price. So they put in 6 quarts - but his car only takes 4 quarts with filter! 2 quarts overfill!! They drained it all out and refilled with 4 fresh quarts after they discovered the error. Waste of fresh oil. I guess whoever looked up the capacity thought it was a V8 Impala, not the V6 that it was - as are probably 95% of the Impalas on the road. 2 quarts too high would not have been good. What do people do who have no car knowledge and just pay the bill w/o questions? I guess this is just another example of why we do it ourselves or watch the guy we pay to do it like we're his prison guard.
