Not so sure it's a good idea to be marketing a fuel that won't pass the water test since it appears that many tracks use this as a basis for what is "legal".
we use only powermist meth and never had a bad batch, in karts, micros or midgets.
they do make a mix called "holeshot" that has a red color and i believe will pass water but not hydrometer.
i was taught to only mix about 2oz of water to 8 oz of a fuel sample with the water test and it should clear out quickly. i have also seen people get tossed supplying a sample that was siphoned out using a dirty hose....finally going in the tank with the fuel sample bottle and getting the sample direct....and it passed.
i was also taught that there are three things to look for when doing a fuel test....color, smell and the ability to absorb water....if you use a top lube, it colors the fuel....yer done before you start....it also (most times) wont pass the water test. as far as smell, powermist has a VERY strong smell but it isnt abnormal....not like if you have nitro mixed in
another way to tell if there is stuff mixed into the fuel is to watch the flame from the headers....blue and orange is ok....green, purple and red isnt
i also learned a LONG time ago.....there isnt a fuel test out there that can be performed in the field that has the ability to find a real good, professionally done mix. as long as the "chemist" knows the tests that are gonna be done, he can mix the goodies to give you the edge you are looking for AND make the tech guy happy....but it does come with a price!
IMO....fuel and tires are the easiest places to start if you wanna go into the "grey area"
