I received my Schaeffer's Moly E. P. Oil Treatment and Neutra today. I figure I will use the Neutra only in the fuel since I am using 3 oz. of Auto-RX in the oil. You can't mix the Neutra and Auto-RX, right? I really like the Chevron oil I am currently using-it seems to run great in a Saturn. But if I am impressed with the Schaeffer additives I am thinking about switching to Schaeffer's oil. I sure wish I had discovered this web site a long time ago. I swear that I can hear and feel the difference in the Chevron oil compared to the Valvoline I used to use. Chevron seems to be one of the most, if not the most, highly regarded conventional oil at this web site. I really liked that Baldwin air filter, but since they have become hard to find, the NAPA Gold (Wix) seems to be performing well. I am still trying to decide what oil filter to use on this car-I think I will try a K&N next time. I am hoping that the Neutra will prove to be a really great fuel system cleaner, injector cleaner, and upper cylinder lubricant.
