Satisfied Repeat Customer

This is my second order of Rx. If you recall, I had severe sludge in my 2011 Infiniti G25 due to poor preventive maintenance and I did your “heavy sludge” treatment.

I am now at the stage of maintenance and will be adding a bottle with my next two oil changes. I have been pleased with the results that I have experienced in my previous treatments.
