ive had mine for about a month now. im averaging about 13 miles from a 30 gallon tank. thats with headers, exhaust and supercharger. i just drive normal nothing crazy.

Holy crap you only get 13 miles out of a 30 gal tank.....That is some bad gas mileage...lol


Hey you word it wrong..

lshatchcx18

nope its correct i drive city a lot. about 80 miles a week on the highway. traffic aint the greatest here u can be sitting in traffic waiting for your turn for a light forever during rush hour. i sat as long as 20 minutes. 20 minutes with the truck running at idle start to cut into your mileage quick.

05 super

yep, at idle you're getting 0 mpg.

thats why I am happy with my 4.2..lol 19mpg

i love the power of the 5.4 and the supercharger. when i bought i knew what i was getting into. so i wasnt and still not worried about the mileage a whole lot.

I can lie any more....I would love to have Harley supercharged...the sound of 2 glasspacks in the morning when my co-worker stomps it going to get breakfest...yea i am jealous but he will never know...

Since you just bought it an have no clue when the fuel filter was changed last, you should change it and be done with it. It takes no more than 5 minutes if you by the filter flare tool. I bought a WIX filter and the little plastic flare tool from O-reileys for $12. They have a steel flare tool but it doesn't fit in the filter ends. The filter is is on the frame rail under the driver door.
I had been using the mobil conventional oil but I switched back to the Ford
syntheticblend. I have an 04 lariat and average about 360-380 a tank.
