AutoRx application for not-quite 100000mi vehicles

[John Smith]

My car is in its rinse AutoRX cycle using dino Havoline 5w30 (1st time use). I used mainly Mobil 1 0w30 and Mobil 1 0w-40 from 60000mi to the present 93000mi. Previous history is not known, but oil consumption is negligible.

My concerns are:
a. The mileage is so close to the 100000mi marker
b. Unknown oil history prior to 60000mi

I plan to use GC or Mobil 1 0w-40 every 6 mo (~7500mi) after this treament.

Is there any advantage to use 2nd AutoRX treament in my case? If I don't do the 2nd treatment, is there any advantage to adding 1/3 bottle of AutoRX to GC or Mobil 1 0w40?


Thanks.

Do the second Auto-Rx treatment your mileage and unknown history of this car make Auto-Rx second cleansing a wise investment. Use 3 ounces of Auto-Rx as maintenance amount in your oil changes after cleaning is done.

Frank, is there any ester ban for the soak cycle
(before rinse cycle)?
