Yeah, I had a similar experience where the tech dumped oil all over my engine bay and all over my brand new AGM battery, and their excuse was, well the guy is new.... Um, well either way it's unacceptable, but great cop out
my family member did the oil changes at Tewksbury Toyota all the time .. well one oil change they pour oil on the engine.. I tell them you have to inspect when the dealership does the work .. so I brought the 2009 V8 runner back to the dealership and they did not charge the oil changes and they cleaned up the mess..
