Hi Guys,
My first post so......Hello everyone
I believe that the Castrol Edge 5w-40 is on the Porsche Approved oils list. I have several quarts of Castrol Edge in 10w-40. I live in South Florida (Miami to be exact) and I recently purchased a 05 Cayenne Turbo with 85K Miles (runs fantastic!).
Since I am in Miami and the SUV will never see temps colder than say 35 degrees F is it OK to go with the 10w-40 instead of the 5w-40 that Porsche calls for? I have about 30 quarts of the 10w-40 Edge but I am willing to buy the 5w-40 if there is any down side to doing this. I want this engine to live a very long and happy life as it has up to now.
Thanks!!!!
