ARX - mileage vs time?

[jheulert]

When using Auto-RX, would there be any difference in the final result if you were to blast down the interstate for 1500 mi in two days, or just drive around town for 3 months with the same mileage? Same amount of miles, but different length of time for ARX to work. Just wondering if I should add it now or after my trip.

Some people believe highway miles are best.

Personally, I think city miles are best.

1500 miles at 70 mph is 21 hours of operation.
1500 miles at 35 mph is 42 hours of operation.

Of course temp plays a major role. So if you average 10 mile trips, and it takes 3 minutes to warm the engine up, then subtract 7.5 hours from the 42. So you still get 34.5 hours of cleaning time at temp.

As you need hot oil trip should be better IMO

Probally a combo of both driving would be best. It most likely does come down to operating time. I used ARX in an old trans for 11 hrs/400mi, a short time, but I had no option.
