Is anyone else getting mileage like this? All I've done is add one bottle of Power Service Cetane boost to a tank full of non-cut summer fuel.

As you can see it's just a little over 55 MPH and I never got mileage this good before. It was usually around 21 to 23.

You can if ya want but I wouldn't rely to much on the overhead "lie-o-meter". My truck says pretty close to the same thing at that speed. I actually figure it at the tank for a real number

 

[Hotshot3500]

my service truck's avg mpg on the overhead is 15 I have to calculate every tank of fuel my best one yet on paper is 9mpg

I can believe it because it always read 21 to 23 on that section of road before and that's what it hand calculated out to. Now I run cetane boost and it's 27 every time even after a reset.

Lol... Congrats on your new found fuel mileage. Try this, next time your fuel light comes on yoir truck should have a distance to empty of like 200miles or something else waay out. Try it see how far you get

 

[dodge man2]

Yeah, don't believe the overhead. Mine always reads something like 21.5 mpg. I wish! Hand calc always comes out 14 to 17 mpg.

 

[Rimcrew]

I got 56 MPG once. I think 75 is doable.

So 600 or so miles between fill ups?

Or is it still 350 miles/tank and getting 27-28 mpg?

I just started using the Cetane boost so it will take a while before I can check, especially when I'm still on "Full" after 30 miles.

Hard to beat 3100 miles per tank isn't it?

Fill up to fill up is your mileage, anything different is denial.

hahaah right on! what ever makes ya feel good!

 

[steve05ram360]

Hey I managed 22.8 mpg (IIRC) on 717 miles, crunched the numbers on what was remaining in the tank and I could have made it to 800 however the tank would have been bone dry by then. Still havent broken into the 23's yet but believe I could if I applied myself more behind the pedals

 

[slowmover]

I don't fall below 24-mpg on highway. Have hit 27 numerous times.

Ya and mine get's crazy mileage going down hill too, and going up hill it can drop down to terrible mileage numbers. My point is I live in a hilly place but at that time in that video I think I was getting close to that mileage even if the wind was to my back side.

This thread is still going. Ugh. Stop it men!! Stupid thread. Should be locked. They've locked ones with more merit

That's because most people never see good mileage because everybody is always in a hurry. There's nobody I know that drives 55 anymore.

 

[Ratdog1]

Then.. I haven't driven my truck for a week .. my mileage just be going up up and then I had to drive it... down the MPGs went down

I do, and I see great mileage due to it :thumbsup:

Dont let the naysaying Nancies get to you.... theyre just pissed off because their truck gets crappy mileage.

Yes, the overhead lies. BUT... it runs off of a constant algorithm. The algorithm never changed, just the variables. So, while you may not actually be getting 21mpg on that stretch of road like the over head says.... its still going to be as constant as the variables. So.... youre driving approx the same speed with approx the same rpm's on the same stretch of road with approx the same weather... and now youre reading 27mpg. The only variable that changed was your fuel/additive etc.. so yes... you WERE getting better mileage.

You may have been getting 18 before while reading 21, and you may be getting 23 now while reading 27.... but the actual mileage still increases, just like the overhead does. Some people just cant grasp this concept. The only know the over head is "off"... thats it. They dont get that youre nto saying youre "averaging" 27mpg. Youre simply saying youre seeing a difference with a rise in fuel economy, because you know your truck well enough to know what it has always registered on that section of road.

Happy youve found something youre happy with :thumbsup:
