Short-acting fuel additives for competition use


  

It is difficult to find a long-acting fuel additive for E85. The opening-time reduction for acetone with glycol is great, but it wears off after only a few hours and after about a day is the reduction very small. Nowadays, I have developed a long-acting glycol additive (AG+), which should have reduced the importance of the following (stated below) additives. Then one should distinguish between different effects, such as an opening-time reducing effect, ignition-improving effect, cleaning effect, lubricating effect, bactericidal effect, etc. Where the latter is beneficial without that it is possible to measure in a simple way - but can purely subjective still be possible to confirm.

The additives reduce the fuel injectors opening time, which means that E85 behaves more like regular gasoline, etc. And in some cases can avoid to take steps to increase the amount of fuel. This opening-time effect also plays a major role in various competitive events or when anyone need a temporary and extra large replacement of the fuel.

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 D66 - then one can prepare 600 ml of diesel first (900 x 2/3). The following components are calculated the same way. To determine the amount of white spirit for the same example; take 900 x 1/3 which is 300 ml of white spirit.

 

D66 D66   label for D66
For both gasoline and E85. Power enhancing and cleans the fuel system.
Dose factor: 0.002 - 0.005 0.2 - 0.5 %
 
2 parts diesel (city diesel/ACP)
1 part white spirit

sum = 3 parts

Commentary
For glycol-based additives works D66 excellent but with no other additives makes D66 great use. E.g. a petrol car that runs with D66 will soon begin to show positive characteristics such as smoother running and more engine power. See the site about X66 for more information.
Consumption gain: Not measured  
  Opening time reduction: 25-30 %

 

 

Di66 Di66 Shake before dosing! label for Di66
For both gasoline and E85. Cleans and load the engine with iron oxide.
Dose factor: 0.005 0.5 %
Phase separated  Clear liquid
5 parts D66
1 part MCO20
4 parts 100% alcohol

sum = 10 parts

3 parts D66
1 part MCO20
6 parts 100% alcohol

sum = 10 parts

Commentary
Often referred to DiG when combined with blue glycol. Dosed always alone - never while an acetone additive is added! Di66 may not be combined with red glycol additives such as G+. Di66 causes a red coating on all internal engine parts including spark plugs. Read the site about MCO20 for more information. See picture at layering after shaking.
Consumption gain: Not measured  
The content of ferrous sulfate: 20 ppm Opening time reduction: 25-30 %

 

 

gas-dryer IPA/gas-dryer    
For all fuels. Power enhancing and decrease consumption.
Dose factor: 0.01 in pure petrol 1 %
 

For 10 gallons petrol dosed 15 oz

For 10 gallons E85 dosed 3 oz

 
Commentary
IPA is temperature sensitive but can be added as a sub component - except for fuels that not containing petrol. Bactericidal function in diesel. See the site about IPA for further information.
Consumption gain: Not measured
   

 

 

Acetone Acetone    
For both gasoline and E85. Power enhancing and decrease consumption.
Dose factor: 0.0018 in pure petrol 0.18 %
For 10 gallons E85 dosed 0.35 oz
For 10 gallons E60 dosed 0.92 oz
For 10 gallons E55 dosed 1.04 oz
For 10 gallons E45 dosed 1.27 oz
For 10 gallons E05 dosed 2.19 oz
For 10 gallons pure petrol: 2.30 oz
   
Commentary
Has major positive impact and added as a sub component - except for fuels that not containing petrol. See the site about acetone for further information.
Consumption gain: 5-10 % (petrol fuels)
   

 

 

The effect of these additives is based on concentrated ethylene glycol and an acetone component. I first developed G+ but when the future is a bit uncertain for this additive, exists the need for an equally good additive but with other components. After many tests and some luck saw at the end DiG (Diesel Iron Glycol) to be a worthy substitute. DiG is slightly sharper than G+ but has some scary features, also may Di66 that is included in DiG not come into contact with undiluted additives as contain IPA, acetone or glycol - during the actual dosage. Although I run several hundred mil with DiG has nothing negative been seen but the risk is not completely zero, and the case probably glycol as an additive in the first place - it is a somewhat odd combination.

 

G14a, which is the oldest additive for E85 is short acting and must be mixed with regard to the proportion of gasoline and ethanol.

As is well known switches the composition of E85 with the seasons and that makes that G14a must be re-mixed when the transition from summer to winter ethanol takes place and vice versa. If UGA is in use one has to fill up the right parts of the fuels depending on the season. The rules on how to fill up is now written down in a crib that can be downloaded.

When G14a shall be converted to winter use, multiply 0.033 by the amount of G14a - gives amount (extra) acetone.

For the conversion to summer use, multiplied the amount of G14a (G9.33a) with 0.355 - gives amount (extra) glycol.

 

 

G14a G14a Shall be combined with D66/Di66 label for G14a
Only for E85.
Dose factor: 0.005 0.5 %
Summer Winter
14 parts G+ or blue glycol
1 part acetone

sum = 15 parts

14 parts G+ or blue glycol
1.5 part acetone

sum = 15.5 parts

Commentary
Also ordinary glycol (conc.) works - without hexamine or Di66 with blue glycol - but then is the improvement compared with G+ or DiG not so important anymore. If this additive is based on DiG may it not be mixed with fuels with G+ additives or vice versa. Make it a habit to always dispense G14a after the fuel is mixed with D66/Di66.
Consumption gain: 0 % Opening time reduction G+ : 40 %
  Opening time reduction DiG: 50 %

 

 

Suppose you are a motorist who has a petrol car, but who lack the ability to experiment with technology, may simply not had time or wanted to put you into the topic of converting a petrol car for ethanol - for you should UGA fit nicely.

These additives makes that you at least can fill up half with E85 and half with E5, or at most 3 parts E85 and 1 part E5. Thus you avoid the risk of a hard starting car when it's cold outside, the water formation in the oil may not be serious consequences, one avoid puddles of water in the exhaust system - such as silencers, etc. and you become more environmentally friendly. Another tendency in a sloppy conversion is that the car will be somewhat difficult to start even when the engine is hot - that's because the engine temporarily get an overdose of fuel.

Not at least will it save you money, provided that the E85 is cheaper than gasoline (taking into account the higher consumption E85 causes). The fuel consumption increases, but it always does with E85 in the tank. UGA does not lower the fuel consumption, compared to E45-E60 without any additive.

It has been demonstrated that UGA-additive can be very opening time-reducing. Especially for the E45 and E60, giving UGA so little need of an extra opening time that the car can be run as if it were fuelled with regular gasoline.

Glycol additives such G14a and UGA shall be dosed after the fuel is mixed with D66/Di66. As the hydrogen in the naphtha reacts with glycol will a sloppily completed dosing lead to the loss of the effect that one should expect from these powerful additive.

 

 

UGA UGA Shall be combined with D66/Di66 label for UGA
Unitary Glycol Acetone - for mixed fuels.
Dose factor: 0.004 0.4 %
E45: 3 parts G+/DiG  &  1 part acetone

E55: 7 parts G+/DiG  &  2 parts acetone

E60: 9 parts G+/DiG  &  2 parts acetone

Commentary
Here is the dosage 0.004 - a somewhat more difficult conversion factor than 0.005. Remember to distinguish between G+ and DiG-mixtures and never let Di66 brought into contact with UGA!
Consumption gain: 0 % Opening time reduction E45: 75 %
  Opening time reduction E55: 0 %
  Opening time reduction E60: 35 %

 

 

Other data:

ADDITIVE TYPE Conductivity ┬ÁS/cm Opening time needs %
E85 and G14a with G+ 20 20.4
E85 and G14a with DiG 12 17.6
E45 and UGA with G+ 3 2.7
E45 and UGA with DiG 3 2.7
E55 and UGA with G+ 4 9.5
E55 and UGA with DiG 5 9.5
E60 and UGA with G+ 5 7.5
E60 and UGA with DiG 6 7.5

Despite that, according to this chart has a lower opening time needs at E55, is the sum of the right-suited UGA-additive - not less than E45 and E60.
