Auto-RX on newer car

[dwmcqueen]

Is there any benefit to running an Auto-RX treatment on a newer car (21,000 miles)?

The oil has been a mixture of Valvoline conventional and now Mobil 1 (PureOne filter). I plan on moving to Mobil 1 w/ Mobil 1 filter (cheap at Walmart) and then possibly to Amsoil 2000 0w30 with either Amsoil or PureOne filer, but have some regular SuperTech 5w30 / SuperTech filter and enough Auto-RX for one treatment

Any benefit to an Auto-RX treatment at this stage? No audible or visible problems have been noticed.

If you have it, use it. You might be amazed in 20K or so of conventional oil - there will be some ring deposits.

I guess the thing I wanted to do was make sure the car was perfect for the 0w30.

The second question is I only have 6 ounces left. An oil change in my car is like 3.8 quarts. At 2 ounces per quart (for recommended Auto-RX amt), that is 8 ounces. Will I be severely disadvantaged in only 6 ounces?

What is the best carrier oil?

I would suggest with a lower dose rate to extend the service interval from 750miles to 1200 or so. Also from reports, a good conventional oil such as Castrol GTX is best for Auto-RX to work with. Hopefully Frank will fill you in!
