From the info I received from Amsoil, there is most certainly a different oil needed for a turbocharged car due to the higher temperatures and differnt lubrication needs of a turbocharger bearing, and the fact that higher temperatures cause breakdown faster, and thickening after "cook down".

I recently inquired about some older model Porsches and got a nice response, so thank you kindly.
I just bought a new Volvo XC90, with their turbocharged 5- cylinder motor. I plan to break-in the car according to the dealer recommendations, and then switch to Amsoil and go on the oil analysis program, as we intend to keep this one for a long time.
I am interested in the best oil recommendation for a turbocharged car of this type. It has 208-hp, and we may elect to have the ECU reprogrammed for some additional power (up to 245, with boost changed from 8 to 14-psi) in the event it is needed for occasional passing and safety reasons, not for hot rodding.
Sincerely, Mr. P
I am a customer: checkbox
