This week end I will have some fuel mileage numbers for the 4 ounce dose. Right now it looks like the pattern I've seen on two vehicles is that it will take one or two tanks of gas run through the engine for the maintenance dose to start showing a mileage increase. I'm working with Barkerman from BITOG. He thinks that Auto-Rx should be added to a brand new car right off the showroom floor and Saturday I will have some lab work that he said will show the positive effect of such a program.
Figures in. Car 96 Volvo Turbo wagon. current odo reading 188,255. Auto-Rx standard treatment done at 146k miles. Oil then Red Line 5w-30. Current oil is RLI 10w-30HD. The RLI has been in for about 20k miles. Commute is about 45 miles one way during the week. First three tanks of fuel before maintenance dose are
25.9, 25.3, 25.8. Fill ups are done each weekend at Costco, same pump each time.
Next three tanks
25.9, 26.8, 27.2
If you throw out the first tank it looks like a 5% improvement. It appears that the process takes a few hundred miles to show an improvement.
