I've had my car in the garage for about a year now with 3/4 full tank of gas. It's been a long time counting but my motor is finally done and I'm gonna swap it back in and was wondering if I should run it with the old gas?

 

after a while water can get into your tank from condensation....

 

yes hydrocarbons (fuel) degrade over time reducing the octane rating get rid of that gas and refill is 3/4 of a tank worth your build?

Drain it...its not worth the risk....Gas does break down. Fuel stabalizers stop gas from breaking down.
