98 Octane 260 GTX 

Sunoco® 260 GTX™ is an unleaded racing fuel that contains no oxygenates and no metallic additives. 260 GTX is a good fuel for many applications that need more detonation protection than typical street gas provides, yet cannot use a leaded fuel. It has been shown to produce repeatable power levels in small block V8 engines to 12:1 compression ratio, and will tolerate more compression in engines with smaller or more efficient combustion chambers. Turbocharged and supercharged race cars that require an unleaded fuel are good candidates for Sunoco 260 GTX.

260 GTX is not a street legal fuel and is for off-road and racing use only. However, it will not harm sensors such as oxygen sensors used in fuel injection systems. It is also an excellent choice where oxygenates such as alcohols and ethers are limited or banned by the race engine manufacturer or race sanctioning organization.

Sunoco 260 GTX contains additives to enhance shelf life and engine cleanliness. However, as with any gasoline, it should be stored in opaque, tightly sealed containers where the temperature is stable. Handled under such conditions, the shelf life of 260 GTX is in excess of 2 years.

$76 per pail 

104 octane 260 GT PLus 

Sunoco 260 GT Plus is a high octane, highly oxygenated unleaded race fuel.

Because 260 GT Plus contains more oxygen than is allowed in pump gas, it is for off-road and racing use only. However, it will not harm oxygen sensors. Due to its high oxygen content, an increase in fuel flow is required to utilize the full potential of 260 GT Plus compared to conventional non-oxygenated fuels.

Sunoco 260 GT Plus contains additives to enhance shelf life and promote engine cleanliness. As with any gasoline, it should be stored in opaque, tightly sealed containers and kept where temperatures are stable. Properly stored, the shelf life of 260 GT Plus is in excess of 1 year.

$80 per pail

112 octane Supreme

Sunoco® Supreme™ is a 112 octane leaded race fuel designed for competition engines routinely operating over 7000 rpm.  Supreme has a high motor octane number and a fast burn speed to ensure engine protection lap after lap and pass after pass.  It is designed for compression ratios up to about 15:1 in small block V8 race engines and can withstand higher compression ratios in smaller or more efficient combustion chambers.  Supreme’s fast burn speed also makes it a popular choice for 2-stroke race engines.

Sunoco Supreme features a comprehensive additive package to enhance shelf life by improving storage stability and minimizing oxidation.  It should be stored in opaque, tightly sealed containers and kept where temperatures are stable.  Properly stored, the shelf life of Supreme is in excess of 2 years.
