Today I had the biggest brian fart of my life. I filled my Powerstroke with premium unleaded. No, it doesnt run real good on gas. Yes, it is very expensive to fix. Yes, I feel like a massive retard. Anyway, they gave me the 34 gallons of gas back, however there was approx. 4 gallons of deisel left in the tank so it is mixed in. I paid $560.00 for that 34 gallons of gas, and dammit I want to use it. The mechanic told me in will run through a carb alright. Will it run through my 450 without harming it. Thanks for your help and feel free to hack on me at will.
