Man I love the smell of T4. Ran it exclusively when I lived in California, for obvious reasons. Oregon has ethanol-free pump gas but I still run T4 because burning money never smelled so good. Non ethanol pump gas is all you need.

VP T4

Bottom line: VPR is the leaded version of T4 fuel, and because of the lead, it is better for two-strokes. Four-stroke owners should use unleaded T4.

Unlike pump gas, which contains ethanol and ultimately leads to a short storage life after leaving the pump, T4 contains no ethanol and can be kept in a sealed container for up to two years.

97 octane rating Furthermore, when riders face extreme conditions, they are usually forced to add octane boosters or race fuel to increase the octane of pump gas. However, T4's 97 octane rating (R+M/2) provides greater protection against detonation.

unleaded It's unleaded and ethanol-free. T4 is a direct pour-in replacement for premium pump gas, which has a short storage life.

Usage: T4 is the four-stroke version of VPR. It is an all-around race fuel for stock four-stroke engines. Preferred engine type: Four-stroke. Antiknock octane: 100.

Using a 4-stroke oil in a 2-stroke engine can therefore disrupt combustion and cause smoke formation and engine degradation.

97 octane rating T4 Racing Fuel is the perfect solution for 4-stroke engine needs. Unleaded and ethanol-free, it contains a 97 octane rating (R+M/2) which improves protection against detonation, delivering up to 2-3% more power and better throttle response than standard or premium pump gas.

However, T4's 97 octane rating (R+M/2) provides greater protection against detonation. VP T4 also offers 2-3% more power and better throttle response across the entire RPM range.

Features: The VP Racing Fuel T4 is designed for stock four-stroke engines. It is lead free and ethanol free. This makes the VP Racing Fuel T4 a direct replacement for pump gas but top of the range. Note that its octane number of 100 (R + M / 2) provides better protection against detonation.

We design VP C10 as the best non-oxygenated unleaded racing fuel on the market. To begin with, it does not contain any metal compounds and will not harm catalytic converters or oxygen sensors. Furthermore, it has a proven performance record, which includes numerous past SCCA and Ferrari World Challenge championships.

TruFuel 4-cycle fuel is ethanol-free and formulated with proprietary additive technology to ensure smoother startups and superior trigger response. It's an advantage you can hear and feel. Your 4-cycle equipment will start and run noticeably better, last longer and need fewer major repairs.

4-cycle engines are usually made to closer tolerances so having oil mixed with the fuel can gum them up and cause overheating. As long as you only add oil to the 2-cycle machine's fuel, then you are fine.
