TERRIBLE. I had every intention of writing these guys a great review, until about 2 days after my oil change when my car began to billow black smoke. Of course I happened to be out of town, but luckily found a car dealership to pull into. The helpful Hyundai techs explained to me that the Jiffy Lube team had overfilled my oil, therefore causing it to spill out, cause that smoke and a huge mess under my hood. Such a bummer. The worst part? As soon as I told the tech what was going on, he asked if I had gone to Jiffy Lube for an oil change recently.... I mean come on, really? He says it's one of the most common things he seems when people come in like this. So no more JL for me thats for sure.
