When I drove around the fall of 2013, I refueled 10 liters of E85 in my Xantia, reset the counter and drove until the car stopped due to fuel shortages. It was quite interesting and at the same times a little exciting. Usually it was quite easy to predict when we had to stop, but on a few occasions occurred the impossible. The engine continued to run despite the over mileage driving. This happened three times!
The total number of driving tests conducted was around 20, or somewhere around it. Sometimes when I was impatient I only refueled five liters. With 10 liters of E85 it stopped somewhere at 95-115 km. When things went really well I reached 130-140 km, which corresponds to petrol consumption. On these occasions there was an overdose of acetone, a slightly smaller amount of glycol and lighter fluid type T66. The exactly constellation could never be ascertained since the impossible so rarely occurred.
I was never able to repeat the golden cycles one after another, which raises suspicions that the cause may have been due to hidden pockets in the fuel tank? The last run that took place with extraordinarily low consumption I used the constellation below and that is why I had it out as a working additive so long, even though I never achieved said consumption figures again. There are suspicions that the cause may be due to new directives in the E85 marketed in Sweden, such as the incorporation of IBA, that took place around 2010-11, or the fact that the E85 is definitely drier now than it was when I busied the most about this 2010-12. Glycol and dry E85 is not a good combination, that has I turned out. So now I allow others to try to figure out how to proceed? E85, which with help of some chemicals can match gasoline from a consumption point of view, is a peculiar phenomenon which probably deserves to be studied more closely.
AG+ reduces the fuel consumption (in varying degrees) for optional ethanol and gasoline constellations and is the only glycol additive that is suitable for T66. Like G14a and UGA reduces AG+ also the opening time and is power-enhancing. It is therefore a fuel additive that is particularly hard to beat.
When a lower ethanol content (gas mixed with E85) than 85% shall be used should acetone be added to AG+. Use this formula: quantity of acetone = quantity of AG+ x 0.0035 x (85-E??). Example: In use of E75 will the acetone factor be 0.0035 x (85-75), ie 0.035. The amount of AG+ multiplies with 0.035 gives the amount of acetone. For 100 ml AG+ shall thus 3.5 ml acetone be added, before it will be dosed in E75
