About a year ago I purchased a 5 year old Ariens riding lawnmower with an 11 HP Briggs & Stratton engine. At the time it was using 3 oz. of oil every 3 hours of running time. I asked Frank Miller about using Auto-Rx in the engine since it holds 20 oz. of oil. He informed me to use 3 oz. of ARX. Each time over the past year that I have added oil I did it with equal portions of Auto-Rx.

Saturday March 11, 2006 I checked the oil before starting the mower and the oil level was on the mark. In about 18 hours of running time on the engine the Auto-Rx had cleaned the rings and pistons and had stopped the oil leaking.
