oil after auto rx

[EP]

Is it ok to use 15-40 delo 400 or 10-30 high mileage oil after my first run of rx? It is time to change my oil. Is it ok to run 3oz of rx in either the 15-40 or the 10-30 high mieage? The rx sure did smooth out the way this motor runs. It works!!

EP,
The 3 ounce maint. dose of Auto-RX will run great with any oil you choose for your oil change. Either of the oils you listed will work fine after your initial clean.

Alot of users have had good results with the maintenance dose of ARX. My thinking is that if you go to the trouble of cleaning out the motor, stay the course and keep it clean.
