ive been testing 93 octane in my 6.2 however i'm seeing terrible mpg. i do all city driving, and its around 13.9 and has brought my lifetime down to like 14 or 15.

are you the first one to take off from a red light? If so that's why the mileage is so bad.

I think if I was a salesmen I would research the products I would be selling. I wouldn't like it if a customer came in knowing more than me.

Mine gets pretty bad mileage at 180 mph. Maybe I should get a bed cover.

This was taken last week when I filled up. So far I have put this many miles on the truck. Hopefully it stays like this. We will see.

You can't just blame driving style. I had a 5.3 with 3.08 gears and my lifetime over 9000 miles was 14mpg. I would drive with the full intention of getting the best fuel economy possible, but it just wouldn't do it. It did have some good moments here and there, but when I went to a diesel 2500 I broke all my mpg records from that 1500.

 

It's a shitty problem to have because the dealers won't help out because it's easy to blame driving style.

I drive on the hard side and don't speed, don't need to in Texas speed limits are high. Im most often first to leave the light, my lifetime average on E85 and some 93 is 16 MPH. Most would be in town.

Not sure how yours was so low. Did you keep the tires properly inflated and all the other jazz that they say is necessary for good mileage? My 5.3 3.42 4x4 CCSB has had great mileage. My lifetime is 16 mpg. With about 85% of that being city and 15% highway. And about 20% of my overall has been with a lead foot cause it's nice to hear the exhaust!

Tires were fine and I was 70 percent hwy. I towed a 6x12 enclosed trailer once for 100 miles and got 6mpg.

Man I don't know what some of you are doing to get such low numbers.

 

DIC shows almost 20mpg, 25 mile average shows 26mpg, 50 mile average shows 22mpg, 400 mile average shows almost 20mpg. My hand calculated mileage shows anywhere from 18.75-20.5mpg on my weekly commute.

That's about spot on what I am seeing with my 6.2. It has settled into 18-19 on my normal weekly driving and if I can get out on the freeway for any amount of time it puts me at 20-21mpg.

EPA sticker on mine said 21 hwy. but I've seen 22-23 cruising between 70-75MPH (not drafting btw, but when I do I get 25MPG). City I can get 16MPG if I play it easy.

 

I've got right around 4600 miles on the truck. CCSB 4x4 with factory wrangler street tires. 275/55/20 5.3L with 3.42 gears.

 

 

Mine used to get around 18-19 mpg hwy. when I bought the truck I got 15-17 on the hwy drive home. But mileage seems to be getting better with more miles.

      MPG at 600 miles

      By Chuck FB · Posted

      There are probably a few threads talking about fuel mileage but this one seemed to fit the stats I have seen based on my typical local driven route but with different outcomes based on different seasons/temperatures. I have a few hundred pounds of items that consistently ride on the truck at all times such as a bak flip cover, rubber bed mat, tools and extra fuel so I would be something over 8100 lb without me in the truck. All these examples are based on a 100 mile round trip to a town plus running around town so maybe 110 to 120 miles in total for a trip. Using regular fuel and I assume it always has some ethanol in it but don't know the percentage they blend in. Also speed wise I am going at 62 mph and non aggressive driving although less speed yet if its crappy winter condition roads. I am going by an initial reset of the computer generated fuel use numbers averaged over a couple of thousand miles or so for each weather/season so they may be more optimistic then actual hand calculated numbers. Basically this is painting a picture of doing the same drive but seasonal conditions and temperature being the major variable to the end result. Oh and although I am in Alberta Canada, I am converting it to miles per US gallon so there is no confusion.    So winter time it gets cold here, no real surprise there and the roads can be clear at times but also often have packed rough snow or are are driving through loose snow ( they do a poor job of plowing the highways ) and yes this includes the extra idle engine time due to trying not to freeze ones butt off. 12.7 mpg is what I was getting during the winter months on average.    Then during the spring when it was around the freezing point and the highways are clear of snow, I was getting around 14.25 mpg.   Summer time, I have been getting around 15.15 on average but certainly some of the trips showed quite a bit better fuel mileage, so much depended on how much or little I had driven around town and number of engine restarts after sitting for a while at each location. But stating a best fuel mileage trip to town pretending that is what the truck gets on average is fooling ones self for sure !.      As I said in a different post, I had driven a 645 mile trip over a couple of days stint to a different destination then these other daily to town examples above, and was done during the summer with nice weather and not bucking a head wind, also keeping at 62 mph and its a rolling landscape type highway drive ( this isn't southern Alberta or Saskatchewan flat lands ) Hand calculated fuel mileage in this case though and it came out to 17.65
