Default VP M3 & M5 vs 99.9% pure methanol

Ok guys, i need a little help here. I've been wondering what the differences between VP m3 & m5 and Pure methanol. I know vp m3 & m5 have nitrometh, but what are the overall power gains? what are the up's and down's?

thanks in advance

M3 and M5 will destroy your pump seals. M1 is the only VP meth you can run.

ok so who sells the best pure meth out there? I have a local fuel research place thats been selling it for over 20 years....they have 99.9% pure, but they sell m1, m3, m5 as well. If i do run m3 or m5, how long will my meth pump last? are there any pumps that can take the m3 or m5 mix without breaking(seals)???

M1™
M1 Racing Methanol has a 99.95% minimum purity - the highest purity available in the U.S. With M1, engines run cooler and are less subject to corrosion. VP uses only lined drums 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 extra boost. M3 offers a wider range of jetting options, making jetting easier and more consistent. For bracket racers, variations in ET 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.

New! 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.
