Getting Poor Gas Mileage

[kcos0320]

I thought I would get close to 325 miles, but I only went 292 miles in my first tank. Is this normal or does it take a few fillups for the gas to get better.

You have to take the miles driven, divided by the gallons of fuel used to go that distance to get a better idea of actual MPG.

@kcos0320 If its your first tank from the dealership, you should work on making sure you follow the break procedure, as you will not see optimal MPG's during that period, give it over 1k to work itself into shape. Most vehicles will not get there stated mileage on the first tank of gas, so perfectly normal.

never use a first tank for comparison. you do not know it was a full tank, how it was driven prior to you taking it, how longer it idled during transports load/unloads which there was a few.

start tracking after the 1st tank.

how many gallons did you fill up after the 292 miles?? 14, 16, etc? There is a thread on MPG... I've only filled up twice and have been averaging 22mpg. On long stretches, I have hit 26-27mpg but city knocks it down some.

That’s actually really good!

Yes I filled up and put about 16 gallons.

Usually the break in periods are 1000-1200 miles. I would check again after that mark. Also which grade fuel you are using as well can factor in.

I have a heavy foot... and do 99% of driving 3 miles or less per trip so average is 16mpg currently. When I say heavy, I'm not drag racing, I honestly don't know how other drivers manage to go so slowly.

hahaha, coming from a hybrid vehicle prior... had to learn to hypermile to get the best mpg. So that habit carried over where I pulse and glide and minimize pressing the gas pedal when its a red light ahead or people are stopping ahead.

I am at around ~700miles since I bought mine.

I drive like a grandpa in Eco mode.

Currently I am averaging 19.2mpg (city only) and I think I can bring this up to like 20 mpg if I tried.

I got 275 miles on 16 gallons of 87 gas. I will try switching to 91 now. The tires are 285/55R20 Michelin LTX AT2.

Non-hybrid: I’m averaging around 20-21mpg after 1900 miles on my ORP. Mixture of city, highway and mountain gravel forest service roads. It helped to reset it after the first 1000 mile break in. Now the computer reads fairly accurate to my math calculations at the pump.

I have noticed that if you’re just idling, it starts to drop fast. Hard to imagine it’s really that fuel thirsty when idling.

The first few tanks (3) of gas noted a ~332 mile range. Now, my range reads ~356. Odo reads ~2,150.
Other things to note, strictly 91 octane and only normal driving mode.

I’d be curious to know if Eco vs Normal mode yields much of a gain?
