Called "menthanol on steroids," VP Racing Fuels' newest enhanced formula for menthanol, "M5," makes more power than any methanol on the market primarily due to improved vaporization and faster burning speed. With upgraded combustion additives and a lubrication additive to help seal the rings, M5 offers up to a 50 hp gain in a 1,030 hp engine and 4-6% more power than standard methanol, while offering the same or better protection against detonation. M5 improves the thermal effciency of the air/fuel mixture, offering a wider acceptable range of air/fuel ratio leading to more consistent performance from run to run.
