Fez Man - I have a car that has been sitting in my garage for 4 years that hasn't been started. Being the lazy fuck that I am I haven't started it in 4 years and it only has a quarter of a tank of racing gas (110 octane) mixed with some 92 octane. I need to fire this fucker up. I have gotten multiple pieces of advice and wanted to see what you think. This is what I've been told so far - 1. Should I add a few gallons of new gas, some fuel injector cleaner, possibly some of that sea foam shit. Jump up and down to mix the old gas with new gas, then fire the fucker up. Change the oil and I'm good. If it won't fire, then go to step 2. 2. Drain the tank, flush it out, refill the tank with fresh gas. Fire the fucker up. Go get the oil changed, and done. The car has modern fuel injection, external fuel pump and the tank has been sumped for racing. Thoughts?
