    Millers CFS 10W50 NT+

    I’ve been using Millers CFS 10W50 NT+ in my 2007 Porsche 911 Carrera S for over 2 years now and couldn’t be happier with the results. I did quite a bit of research before choosing this oil, and I’m glad I made the switch. My UOA’s have shown a significant reduction in wear metals, and the oil has maintained its viscosity between oil changes. While this is labeled a “racing” oil, it has a very robust detergent and anti-wear package that holds up well to a 1-year/5k mile oil change interval. In addition, Performance Racing Oils has always provided great customer service and prompt shipping.

    This oil is specified by Hartech, the builder of my special. 3.9 liter Porsche M97 engine. I paid a lot for this engine, and I trust the expertise of Hartech, so I do what they say.
