VP110 vs. U4.2 for 2 strokes?

[brian2372]

looking 4 any opinons ,i race a cr250 with the EG mo better in hare scrmbles/hare and hound .I mostly run pump gas for practice and vp110 for the races but was wondering if all the hype about the U series gas is true.do you have to rejet ,does it make a noticable in crease in power and hows its shelf life?

Oxygenated gas is the cats meow with 6% O2 it offers great throttle response and horsepower gains. Vp 110 is just leaded non-oxy fuel with no high energy component to spice it up. People on this forum have done back to back tests with 110 and pump fuel and there is no gain. MTBE is the oxygenate in U 2 4. There is also alcohol oxygenates. Like U2e has an ethonol oxygenate.
