For the ones I am asking, you should be aware that VP Fuels has three different methanol grades, M1, M3 and M5.
Which one is best when running a water/methanol set up? The purer low grade or the higher grade with the additives?
I pasted the info from VPs site below.
M1™ M1 Racing Methanol has a99.95% minimum purity - the highest purity available in the U.S. With M1, engines run cooler and are less subject to corrosion. VP uses only lineddrums which prohibit rust, corrosion and metal deposits that can contaminate fuel delivery systems. Recommended for all methanol-legal racing applications.
M3™ Like M1, M3 starts with methanol of the highest purity, but includes lubrication and combustion additives for an extraboost. M3 offers a wider range of jetting options, making jetting easier and more consistent. For bracket racers, variations inET from run to run will be substantially reduced. With better tuning and cleaner, more efficient combustion, M3 makes more power and yields better throttle response than any standard methanol on the market. M3's improved combustion also reduces the noxious fumes associated with methanol fuels, so it's much easier on the eyes and nose. For 60-70% of methanol applications, M3 won't require jetting or timing changes-just pour it in and get an immediate performance improvement in all areas. In the other 30-40%, M3's added vaporization may actually hurt volumetric efficiency and performance, which is what lead to the development of M5. M3 is not pure methanol and won't pass a water test.
M5™ M5 is simply the best performing methanol on the market. With its upgraded combustion additives, M5 will make more power than M3, i.e., 5-7% more power than standard methanol, while offering the same or better protection against detonation. Like M3, M5's improved vaporization offers a wider acceptable range of air/fuel ratios and tuning. It also yields faster combustion speeds which lead to closer EGT's from cylinder to cylinder, providing more consistent performance from run to run. M5 is not pure methanol and won't pass a water test.
