Sunoco 260 GT Plus 104 Octane, Unleaded Racing Fuel

This fuel is sanctioned by: RUSH Racing Series 

Sunoco 260 GT Plus is a highly oxygenated race fuel that will not harm oxygen sensors. It is a popular choice for Crate Engines, Motorcycles, ATV's, Karts and highly tuned vehicles. 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. 

Note: exposure to sun light (ultraviolet light) can degrade the octane of this fuel and must be avoided.

    This fuel performed well. Good bang for buck. I wasn’t tuned for this specific fuel but just the 104 octane level.

    Shelf Life

    Posted by Lequarios Thames on Jan 17 2022

    The 1st drum I received has been good, I haven’t used all of it yet. The 2nd drum I received is really faded and dented. I’m worried about the shelf life or if it was sitting in the sun for too long.

    Some good stuff

    Posted by Adem C. on Jul 08 2019

    Wanted to push my car a little harder than normal at the track so decided to run some race fuel since it was approved by the tuning software and the car really wakes up, pour and go baby just how I like it.
