My general fuel additives cover both E85, gasoline, diesel and also the experimental additive dEC+ can be found. They are based on various naphtha products, diesel, acetone, alcohols and IPA. They are carefully tested chemical constellations that work. Fuel additives for E85 are T66 and the new SH +. ISO can be seen as a universal additive but is well suited for diesel. For gasoline we have A40 and AXg. Even D66 alone works well for gasoline. AT2 and AG+ are two special additives which still are under development; you can study them here under NAMAG. If you drive on E85, then click on ”Glycols Additives” - they are effect enhancement (opening time reducing). All additives are long-acting.
Apart from a certain opening-time reduction (increment of power) seems the additives; cleaning, lubricating, water absorbent and for diesel; both cleaning and bactericidal.
The power increase does not depend on that the energy in the fuel has increased but that the burning has become more efficient and faster.
The procedure for preparation is to first determine the amount of an additive that is desired, then multiplying the amount with - the component through the ”sum”. For instance, suppose we want to have 900 ml of T66 - then one can prepare 600 ml of lighter fluid first (900 x 2/3). The following components are calculated the same way. To determine the amount of diesel for the same example; take 900 x 1/3 which is 300 ml of diesel.
Here are four long-acting additives for gasoline and diesel but ISO can also be used for E85. In gasoline is both acetone and IPA additives stable unlike for E85. There is no clear correlation between acetone volatility versus an additive stability (long-term effect).
Two additives that take into account that practically all gas today contains 5-10% ethanol. AXg is the first fuel additive that combining both acetone and IPA. D66 can be incorporated which simplifies the dosing process. The fuel consumption always increases with ethanol but with AXg is my hope that this gasoline will reach its old position again. Even low octane gasoline can enjoy the benefits of AXg.
