I have a 1994 Volvo 850 turbo wagon with approximately 135,000 miles on it. I have done 1 Rx treatment and rinse and am now on the second treatment. I recently had my car in the shop and the pvc system was clogged; the shop cleaned it out. Do I need to do a third treatment since my pvc system was clogged the first time, or does this matter?
No. You should be fine with the second cleaning rinse application. However I would suggest the maintenance dose after the second rinse, especially due to the turbo.
