HI, i was wondering why and is there anything i can do to keep my gas from burning up so quick. it is basicly when i hit the gas pretty hard. and i know it burns up more but, it seems like the gas gage goes down faster than it should. is there anything i can do to keep it from doing that?

If it is a subconscious thing you might find comfort with a mpg app. I felt that way after switching to an SUV, but the Mpg app keeps me straight.

Ok cool. And I haven't changed the plugs in about a year :/ but I changed the filter about a month ago. Is there something that I can add to the fuel?

????????????????????????????

Sorry, but have you read your post?

The way internal combustion engines work is by burning more fuel when you accelerate faster (push the pedal down).

Slower acceleration "not" hitting the gas hard will ensure your gas gets used less = better mileage.

I Had The Same Issue

I had the same issue with my '05 TB so I threw on a K&M air filter and started using a fuel additive and I have noticed more than a subtle difference in my gas mileage...It may not work for everyone but it worked for me, which is a good thing, considering I have a 3,200 mile trek to Maine ahead of me! I can use all of the gas mileage I can get!!

What additive did you use?

The needle on the level coming down fast isn't a true indication of the mileage, have you done a recent MPG calculation? - You may find the mileage hasn't gone down, you're just driving more.

Our trucks as indicated run around 5,000 lbs with driver on board and a few items. I've done everything that could potentially aid mileage, short of an engine/tranny swap. In around town (suburban with some traffic), I run around 17.3-17.6, depending upon weather. Get on the highway and it's around 22-23 mpg at speeds above the limit to keep up with traffic. (Keep it under 65-70 and I can pull off 25 mpg on reasonably flat or rolling hills). BUT that's with a Tune, Intake, Exhaust, e-Fans and synthetic fluids all the way around.
