I have a 2013 Volvo S60 T5, that has been consuming a lot of oil lately and I was hoping to get the proper procedure for the Berrymans B12 Chemtool piston soak on the 2.0 liter engine.. I was successful in doing the Berryman's soak on my daughters Audi A4, but didnt know if the engines are relatively the same, and if I could do the same procedure as I did on my Volvo. Any information would be greatly appreciated!!
