I looked though out this forum and have not seen anything I am wondering per everyone's computer how much does it say miles to empty on a full tank on the 33 gallon tank
Depends on what kind of mileage you were getting, as the computer adjusts accordingly.Ok I am wondering if something is wrong with my gas tank because i have the 33 gallon gas tank but yet am lucky if my computer says i will get 450 miles to empty which i feel is low for the 33 gallon tank i know there may be different variables but i feel computer wise i should be in the 500 miles to empty at least on a full tank
The vehicle mpg tends to display the latest mpg that you were doing. On your 590 mile trip did you have some low mpg numbers earlier?Just filled up after a road trip. Computer indicated 590 miles to empty. It also said I averaged 20.1 mpg on the tank but actual math showed 18.1
You should see better economy on 89, since that's the optimal tuning for your truck. You may not see enough of a difference to justify the uptick in price. Personally, I run 93 most of the time. But I put very few miles on my truck and pay for the higher grade for a bit more "shelf life" as much as for performance.I got my truck about a week ago and have averaged about 14 mpg over 250 miles -- haven't had to fill up yet and showing about 200 miles left to empty. Probably a combination of the fact that these hemi's don't get the best mileage and I've been trying to give it some gas randomly to follow the engine break-in instructions. I'm curious if over time as I start running it a little more steadily and the engine breaks in if I'll see the mpg increase.
Coming my from F150 that averaged almost 20mpg average over 120k miles (albeit with only 275 hp and an aluminum frame), this is pretty sad in comparison for mpg. Good thing I have a company gas card though
Does anybody know how mpg is affected by using 87 octane vs 89? I've never owned a truck that was recommended to use 89 octane until now. Is that supposed to help or hurt mpg?
