VP Racing Fuels U4.2
VP Racing Fuels U4.2

SAN ANTONIO, TX (May 15, 2007) – VP Racing Fuels, Inc. announced the introduction of the latest generation of its U4-based fuels – U4.2. Following on the heels of its U4.1 introduction, U4.2 is designed as a direct pour-in replacement for its original U4 racing fuel blend. “While U4 makes up to 6% more horsepower than pump gas, it necessitates draining the fuel system between uses due to potential residue build-up in the carburetor,” said Steve Burns, VP’s President and CEO. “U4.1 addressed the residue issue, but requires substantial jetting changes to achieve optimum tuning. U4.2 combines the best attributes of both fuels by offering the same power, no residue and less odor, while requiring little to no jetting changes. The biggest jetting changes we’ve seen required for U4.2 are +2 main jets and +2 pilot jets. Relatively speaking, customers can simply ‘pour in the power’ and be on their way.”

“Like U4 and U4.1, U4.2 is designed for engines with 10:1 to 12:1 compression, but significantly, U4.2 has a much higher octane rating than either of its predecessors,” Burns continued. “For customers, this means even greater protection against detonation. In addition to motorcycles, this fuel will work great in Quick 16 drag racing at compression ratios up to 14.5:1.”

“There are always improvements that can be made,” Burns added. “We’ll never be satisfied until we’ve explored all options for providing customers with the best technology and performance possible. Fortunately, as a relatively small company we have the ability to move quickly to introduce the newest technological developments to market.”

U4.2 is designed for all 4-stroke applications as well as stock 2-strokes. Although U4.2 is illegal for AMA Pro Racing due to its oxygen content, it’s still legal for AMA amateur, CCS, WERA, AFM and club level racing.

Use of U4.2 will yield faster and more responsive engines without harming carburetors, O-rings or gaskets like some other race fuels will. According to Burns, its power gains compare to VP’s best AMA Pro level race fuels for less than half the cost – a comparatively easy, inexpensive way to generate additional power. For example, a new exhaust system wouldn’t generate as big a power increase and the increase would be on a smaller slice of the RPM range, while U4.2 produces power gains at all RPM levels.

Over its 32-year history, VP Racing has fueled champions in virtually every racing category and class -- from drag racing, road racing and circle track to motocross, off-road and off-shore. VP has earned a reputation for producing high quality racing fuels with superior power and consistency – as illustrated by its sweep of all AMA Pro Racing Championships in Superbike, Supercross, Motocross and Supermoto in 2006. VP is also the official, spec fuel and/or contingency sponsor of AMA Supercross, AMA Motocross, Prostar AMA, NHRA, SKUSA, Stars of Karting, Rmax Challenge and numerous other sanctioning bodies.

In addition to fuels, VP’s product line includes performance chemicals, specialty lubricants, traction compounds and racing-related accessories – each designed to produce the most power and best performance in their respective racing applications.
