I just got gas in my 08. I was figuring my Torco mix 1.6 oz per gallon x 14.6 gallons. I went to set my trip and decided to check my mileage which I never do but my buddy had multiplied my mix still had his I-phone out and I said hey divide this out. It was 292 miles divided by 14.65. Thats 19.9 miles per gallon. I was totally amazed I was expecting about 12 miles per gallon. I usually have about 4 to 5 spirited runs per tank. The rest of the driving is highway and city. This car made 630rwhp and 613rwtq a few months ago. I posted the dyno runs on the General Viper discussions under dyno day. The mods are Belangers, hi flo cats, exhaust, Mopar PCM with Torco mix to 95 octane. Thats it. This car is something else.
