A good fossil oil doesnt to the job worse than syntethic oil my 9000 2.3T has now over 420000km on the same turbo and i have never used any syntethic oil i dont use my car in the dessert or in the arctics so there is no need to pay more than you have to.(The fossil oil lubricates better) /K Robert L.
