It shouldn't hurt a thing. Auto-rx doesn't contain solvents, so it won't affect the viscosity of the oil. Plus with a clean engine, the oil run after the treatment doesn't have to work as hard. So it's additive package won't be depleted as fast. Based on what I have learned, I should seequote:

Pat, I don't know if using Auto-Rx prior to MaxLife is a good thing. Some residual Auto-Rx may reduce the viscosity numbers or affect the analysis in some way. Terry may be able to help here.quote:

less oxidation, less nitration, and a stronger TBN after using Auto-rx.
