I use 3 oz. of Auto-RX in my oil as a maintenance dose. Can I put 4-5 oz. of Neutra in about 500 miles before oil change even with Auto-RX in the oil? My car is a Saturn and Saturns may be kind of sludge monsters like some of the Toyotas allegedly are-maybe not as bad. My car takes 4 quarts of oil.
 
IMO, I would use caution on this as the 2 formulas are very different chemistries, best case you will neutralize the Auto-RX with the more active solvency in the nuetra.

Then I would expect the solvency of the nuetra to volatize off,leaving not much cleaning action from either.

Chemists here may have more scientific advice.

Auto-RX works real well with Schaeffers motor oils but I doubt it will with neutra.

Now Auto-RX in crankcase and Nuetra in gas tank is perfect technique !
