I do not know if it is billet, or not so based on that I will keep the bronze gear. I also use 15/40 and let engine warm before I drive it.The
oil arguement is one that can go on forever so I do not wish to go down that road let me just say I did my research and for me that was the best option. My
oil pressure readings are always perfect no mater the temp even idle pressure stays right were it should.
