My car has been into the shop a few times over as many months. The dealer claims there is some sort of goop/sludge in the engine. This is the cause of a MIN oil light to come on. Anyway, the sludge is supposedly clogging the oil sensor causing it to fault. The dealer wasn't for sure because they didn't pull the oil pan? So I got my car back with the same problem and the diagnosis to get an engine flush; this would clean out the sludge and then I could go with mobil 1 for the winter (what grade?). Problem is the dealer doesn't have the flush equipment (they were suggesting some type of pressurized recirculating flush). So now I have an appt to have the engine cleaned at a local place but they want to use this kwik clean engine stuff. A different treatment for your engine. You put this crap in the car and drive around for an hour. Next drain the engine oil and flush out kwik clean and congealed sludge. The guy says it will come out like tar. Now I am worried that it will clog my turbos during this one hour joy ride and blow them? Anybody have any experiece with kwik clean, should I hold out and find a place that does a true pressurized cleaning? Any ideas in Boulder?
