I got a mustang 1997 GT . the engine is rebuild and we make the engine flush and put the pennzoil platinum sintetic 5w30. I think is to thin for the engine. I life in puerto rico and is very hot her. Shut I change to 10w30.
Thanks ! Im exited to receive awnser ! Im new in the forum and is very cool. I will use 10w30 and we change the time chain kit and some other stuff. But is not a new engine we do like a refresh.
