I want to warn you by my example. I stopped by to change the oil-they splashed on the engine a little near the filler, for the type they poured and made a change of the lambda probe, suitable in appearance but with a different thread. It was in the evening, so I noticed it only the next day, went to them, there was no dialogue, immediately aggression. Thank you, at least the oil filter was changed, so the engine would have killed in general. Then I only found out that these "masters" had already been shot a couple of times. That's it, be vigilant
