Choosing a Motor Oil for your Auto-Rx Motor Cleaning Application
Auto-Rx is compatible with all 4 stroke motor oils. However, for the best results, conventional, mineral oil based motor oils work the best. The normal cleaning and rinse phases of an Auto-Rx cleaning application, is only for a relatively short duration of 3000 miles. In nearly all cases, conventional oil will provide the same level of lubrication, as would an expensive full synthetic motor oil for such a short duration. Auto-Rx is more active in simple conventional oils.
If you feel that you would prefer to run Auto-Rx with a group IV full synthetic oil, then merely increase the cleaning time to 4000 miles and same for the rinse.
If you are running Auto-Rx to solve a rotary seal leak in a motor, using conventional oil is a must for both the cleaning and rinse phase.
For heavily sludged motors, we highly recommend running conventional oil for cleaning and rinsing.
We do not recommend running oils badged as High Mileage oil for the best cleaning and rinse results in heavily soiled motors or those with seal leak issues.
