A friend received a car as a gift because it smoked, would not pass smog and did not run well.
I helped with a tune up and we purchased a case of gallon jugs of Delo 15w40 from Costco and ran two back to back 2-bottle doses of AutoRx. We just finished using 4 bottles of Auto-Rx, 6 gallons of oil and 12 filters from our fleet filter sponsor. The first filters came out with just a little [censored] but later filters came out completely krapped up, filled with dark heavy sludge. The compression came up and the car after a careful tune up passed smog.
1998 Honda Accord, auto transmission
starting mileage 134,208
ending mileage 142,014
starting compression 1=125, 2=130, 3=175, 4= 100
ending compression 1=180, 2=175, 3-180, 4=170
starting mileage 19mpg
ending mileage 28mpg
You should look at the change in fuel mileage, not the actual milage because it has more to do with driving conditions and driving habits. This guy does not spare the whip and I encourged with the idea that the clean and rinse might work better if the engine had some work to do. Also you have to take into consideration that there was the tune up done but I think the results are a product of both. A tune up could not have rasised the compression.
I have come to the conclusion that the double bottle dose is good for really bad engines but the 1 bottle does will work for everything else and it's a good idea to repeat the 1 bottle dose with higher mileage. You may think you have everything but a second round is useful to get the last bits.
Rough cost figures are $100 tune up parts, $56 oil, $50 filters, $40 for Auto-Rx. The car now passes smog and runs really well and he'll make back the investment with the improved mileage. The previous owner will not believe that we didn't overhaul the engine. Behind his back his wife told us he order some Auto-Rx.
We also ran a 1-bottle dose on a vehicle with 20k miles and there was an improvement in fuel mileage from 16.5 to 17.5 on a V8 4Runner. The fuel mileage was done at the pump over 4 tanks before and 6 tanks after. This vehicle commutes on the same trip 5 days a week, a pretty constant use. It's driven by the guy's wife and she is much more mature in traffic than he or me.
The maintenance dose is important but I think the new vehicles can benefit as well. The idea that a new vehicle needs no help might need to be looked at more carefully.
