Yes, I am glad to say Marc is still here and as busy as you can imagine.
However, the gas and diesel formulas are NOT the same thing. The diesel formula is stronger and as noted above, is a more concentrated formula. You can use the diesel formula in a gas engine without any harm.
There are two versions of the gas formula - the Marine formula and the Small Engine Formula. The marine version is a more concentrated formula, since boats have large fuel tanks. The SEF formula is easier to use on a bike (1 ounce to 6 gallons) and it is available in a new one-ounce bottle. We call it the Star Tron Shooter.
Star Tron was introduced long before ethanol was added to gasoline. While it is a great way to mitigate the problems that adding ethanol (alcohol) to gas causes, it is also a great way to improve 100% gas, too, if you are fortunate enough to have access to the real stuff.
Star Tron uses enzymes, unlike any other fuel treatment. It allows the fuel to burn more completely, which means engiens start easier and run smoother. It also restores a lot of the power and cruising range lost to ethanol. It also prevents the formation of the gums and varnish that clog carbs an injectors so quickly.
The formula is pretty simple: 95% petroleum distillates (fuel) and the remaining 5% is a proprietary blend of enzymes. The enzymes do all the work - the fuel base allows it to be added to any fuel safely. You can't overdose this stuff. It has 0% alcohol.
Some people believe it is the fuel base that does the work. That'd be a good trick since you only add one ounce to 6 gallons of fuel. One ounce of fuel to 6 gallons of fuel gets you nada. The enzymes are what make the good things happen. It's like Coke or Pepsi in that way - they are mostly water, with the secret ingredients that convert that water into Coke (or Pepsi).
It's tough to compare it to other additives, since it uses enzymes and they don't. It does stabilize fuel, but you need to do more than that. It enhances combustibility, allows water to be dispersed throughout the fuel as very fine particles that can be vaporized with the fuel charge (you can't make water burn or magically disappear) to help prevent phase separation and corrosion. It also removes debris such as gums, varnish and carbon deposits. We back it up with a money-back guantee, but more importantly, we use the stuff in all of our bikes, cars, trucks, boats, lawn mower and gas-powered margarita mixers.
