I took 3 cars in for an oil change. 2 of my 3 cars had problems following the oil change. One car was taken to the dealership 3 days after the Swis oil change due to a recall item that needed to be taken of. The dealership informed me that silicone was used in place of the oil pan plug. I questioned Swis and they denied using silicone. Really?! The second car suffered severe difficulties (costing approx $2500) 13 days after the oil change - coincidence? Possibly - but 2 cars out of 3 having problems within days of the Swis oil change. I don't like the odds and will not return for any type of service.
