Sunoco Evo 10 105 Octane, Unleaded Racing Fuel is Sunoco's highest available octane in an unleaded fuel.
This fuel is sanctioned by: ANDRA DRAG RACING and IHRA Motorsports
Sunoco Evo 10 is a high octane, highly oxygenated, unleaded race fuel. This fuel pushes the unleaded octane limit to new heights using highly refined ingredients. Evo 10 produced a 17% HP gain against 93 octane pump gas when tested at our local performance tuning shop. Their race tune took full advantage of Evo 10’s high octane and extra oxygen on a boosted V8 engine. This fuel will offer added performance to naturally aspirated engines as well. Evo 10 is designed for full race applications and applications that can run street/race tune.
Sunoco Evo 10 when properly stored is stable for 2 years and is safe for oxygen sensors and catalytic converters.
Note: exposure to sun light (ultraviolet light) can degrade the octane of this fuel and must be avoided.
SUNOCO TECH CORNER
The 105-octane rating of Sunoco’s Evo 10 might not sound like a big jump up, but this fuel is highly oxygenated via an extra dose of methanol. That methanol will help reduce heat, Sunoco's Santner explains, a big plus for forced induction engines. The cautions here? Special handling, since this fuel also contains MMT and, again, more tuning. “You’re going to need 5% more fuel volume than GT Plus,” Santner advises.
Sunoco’s oxygenated fuels contain alcohol, and that alcohol helps performance. Alcohol can have some drawbacks, though: Proper storage becomes key when you’re talking about fuels containing alcohol. Alcohol is also such an effective cleaner that it could loosen deposits in older, dirtier systems and clog the fuel filter.
