ENGINE SLUDGE

I would call Vovlo North America customer service. A lot of turbo engines need synthetic oil for the turbo to be well protected. My Saab 9000 used convention oil I changed it every 3000 miles and the turbo was still fine at 175 000 when I sold it.

i have been told the same thing ,,only at 44,000 miles ,,but the dealer is taking care of it ,like the previous answered ,,call Volvo !

check your oil trap..if u have smoke coming out of your dipstick and it wont idle right..its clogged..shame on the dealer.they need to look into this..
