Auto-RX just installed

[MustangGT]

I ordered (2) bottles of autorx for our 1992 Buick Skylark (122,000 miles), I decided to start out with clean oil (havoline 10W-30) rather than just adding the autorx to the existing oil. When I opened the autorx bottle I was suprised that it looked so dark, almost like chocolate syrup, and it seemed kind of thick too. I'm hoping to maybe get 2 or 3 more MPG after two treatments, has anybody achieved this? The car has had very frequent oil changes since we've had it, but the first 80,000 are a mystery alas the autorx.

My milage seems to be improved. I drove the car before the auto-rx and now my wife drives it. Because she drives faster than I do kind of hard to tell. During the first treatment while I was still driving it seems the milage went up. On my final rinse and my oil consumption issue is gone. Before auto-rx 1 quart of 20w-50 in 500 miles. Last 500 miles no consumption. Power is up for sure.
