MX Midwest carries only VP Racing Fuels and has supplied fuel for some of the world's most famous ATV riders. MX Midwest stocks the following list of fuels:
MOTORSPORT 105L
Formulated for stock applications with CRs below 11:1, e.g., Stock Eliminator type racing engines. Offers the benefits and octane of a leaded fuel at a lower cost than more exotic race fuels.
Color: Orange
Motor Octane: 101
Specific Gravity: .745-.760 at 60° F

VP RED
A great standard grade of racing fuel. Used in higher compression race engines up to 13:1, for any application where cost is a factor.
Color: Red
Motor Octane: 105
Specific Gravity: .730-.745 @ 60° F

VP-110
Not your "standard" 110! Highest rated MON of any 110 fuel on the market. Formulated for use in naturally aspirated engines with CRs up to approximately 12:1-13:1. Good lower cost alternative.
Color: Purple
Motor Octane 107
Research Octane: 113
R+M/2: 110
Specific Gravity: .720-.735 at 60° F

C12
The best all around racing fuel made. Recommended for CRs below 15:1, satisfying the needs of 75% of today's race engines. One of the winningest fuels in racing history, including Modified Tour, GNN, D.I.R.T., Indy Lights, NHRA, AMA as well as other local and national championships across the U.S. and around the world.
Color: Green
Motor Octane: 108
Specific gravity: .717 at 60° F

VP113
Offering substantial power gains at a competitive price, VP113 is oxygenated to street gas levels. Formulated for naturally aspirated engines with CRs up to approximately 14:1. VP113 makes up to 2% more power than competitive 110 octane fuels, with gains of 3-4% in engine applications with poor or marginal fuel vaporization qualities. VP113 burns cooler, ensuring power is maintained throughout the longest races and harshest conditions. May require a tuning change, including increase in jet size for optimum performance.
Color: Green
Motor Octane 109
Research Octane: 118
R+M/2: 113
Specific Gravity: .718 at 60° F

U4.4
If youre not bound by fuel rules, this leaded fuel is the best choice for virtually any powersports application, offering the biggest gain vs. cost of any performance part you can buy. The latest generation of our U4-based fuels, U4.4 makes up to 6% more power than pump gas across a wider range of applications than its predecessors. It yields no sticky residue and is more resistant to heat. Designed as a direct, pour-in replacement for pump gas, it will require modest jetting changes, i.e., +2 main jets or +2 pilot jets at most. With its higher octane rating, U4.4 is designed for use in stock and modified 2-stroke and 4-stroke applications. U4.4 passes fuel rules for AMA Pro/Am, CCS, WERA, AFM, NMA, WORCS, SCORE and Best in the Desert as well
Color: : Light Green
Motor Octane: 103
Specific Gravity: .763 at 60° F

MRX01
Recommended for 2- and 4-stroke applications. Delivers up to 6% more power than pump gas and any basic nonoxygenated racing fuel. Excellent for high compression road race applications. Can be mixed with MR9 to raise octane level for specific applications. Clean burning leaves intake and exhaust valves virtually free of deposits for maximum airflow and performance from start to finish. AMA legal except Supercross and Outdoor Nationals.
Color: Pink
Oxygenated: Yes
Motor Octane: 98

MR8
For use in 125 and 250 GP 2-stroke bikes and karting applications requiring high octane values. AMA legal except Supercross and Outdoor Nationals. Fueled the 2002 and 2003 AMA 250 GP champions. For optimum horsepower and performance, do not store this fuel in vehicle drain fuel system.
Color: Yellow
Oxygenated: Yes
Motor Octane: 107
Specific Gravity: .730 at 60° F

MR9
Designed for 4-stroke applications that can tolerate lower actane values. Makes up to 8% more power than pump gas and up to 2% more power than MRX01. Although currently not legal in AMA Pro Racing, MR9 passes fuel rules for AMA Pro/Am as well as club level racing, SCORE, Best in the Desert and more.
Color: Clear
Oxygenated: Yes
Motor Octane: 87
Specific Gravity: .718 at 60° F
