| I used the BMW one. I am sure it will work for the next 3000 miles anyway. I used Moil 1 for the first time since my Amsoil has not yet arrived.
The engine revs more freely than the 20W-50 Castrol I used. It may have freed up some horsepower, but who knows. I am glad. I am switching all my fluids to Synthetic as we speak. |
