I'm draining the tank on my JrZ in preparation for a respray. I have a "hotted up" 2L in the car and have been using 105 octane race fuel. The fuel has been in the car for about 3 years (as well as two 5 gallon containers in the shop. The fuel has been kept cool and not been exposed to temperature variations. It still smells as new (wonderful!). What's everyone's experience with the shelf life of race fuel?
