From time to time you guys may know me as advocating the 3oz maintenance dose as it has worked well in my vehicles. One such vehicle is on a prolonged diet as I want to see if the maintenance dose will keep the engine clean over its life without any further cleanings.
Today something happened that I cannot explain, yet it all makes sense.
I have a Saturn which received a full clean/rinse phase at the 36K mark when I bought it. At 40K it received M1 5-30 diet, at 50K it received Amsoil 3k diet. No difference between the oils, yet today it hit me that I did not use the 3oz maintenance dose. So I add in auto-rx in precise measurement and take off for the store, 51k miles on the odometer. Right from the get go I noticed a much smoother idle, much better acceleration, and more torque in the lower RPM range. WOW, I do not recall anyone here mentioning that when using the 3oz maintenance dosage that their engine would run much smoother. The difference was so great that it could not go unnoticed, this is not my mind playing tricks on me as I got to drive the car for 2 years through all seasons.
This can probably be explained by the extra lubrication that AUTO-RX provides, thus causing less friction, less drag, which in turn bumps the horsepower and the engine seems more responsive. Great product Frank!

A reasonably good quality 10w30 SM oil with 3 -5 ounces Auto-RX is a good regimen for you without seeing a lubricant analysis.
