Let's talk MPG. How low can you go?

[TexasJack]

9 to 10 miles per gallon.

I credit that low number to all of the armor I have added , the heavy toyo 315 mts, the 3/4" marine plywood drawer system and the 500 lbs of tools I carry around.

I got my 95 in 97 with 20K miles on it and it was like new. I think I only got about 14 to 15 mpg back then.

I try to never drive over 25 miles once the light comes on. Why tempt fate? Running out of gas on a busy freeway might be the last thing you ever do.

If I am driving into the back country in West Texas I always carry three 5 gallon cans in the Slee can carrier on my back bumper. You can get more than a tank of gas away from a gas station on some of the back-roads out there. I sometimes mule deer hunt out near Sanderson, Texas. If you fill up at the last stop coming in and don't drive past the ranch to Sanderson to fill back up before you drive out onto the ranch, you'll run out of gass on the way out. Sanderson is where they filmed "No Country for Old Men". Being 60 years old, I can identify with that movie title. It is some tough country out there.

We only get about 14.5 mpg on my wife's 2007 Lexus LX according to the on-board computer.

Have people seen noticeable mpg increases with new oxygen sensors? Mine are still functional (no codes or drivability issues) but they have logged 10 years/150k miles and are likely past their peak.

I'd like to get into the 14's on the highway instead of 13's and think a fresh pair might help.

First tank I 8.1 MPG mostly from the previous owner, replaced the o2 Sensors and 14.7 MPG

The O2 sensors were Toyota and not original couple of nuts were rounded, I replaced with Denso from NAPA.

My experiences with in tank pumps, the fuel surrounding the pumps keeps the pump cool. I've had better luck with vehicles that don't go to the bottom of the tank versus ones that are refilled on fumes.

Speaking as a mechanic, you are sooooooo right with that sentence!

I've been tracking my mpg since I bought my 80 - over two years now. I am holding steady at 12.9 average mpg. That's rolling on 35s with 4.88 gears. My low fuel light comes on pretty much the instant the needle hits E. Supposedly, this means I have 5 gals in the tank. That's 64 miles till shut-down.

My UltraGauge (just installed) seems to be spot on with these numbers. When my fuel light came on, it claimed I had 60 miles DTE.

Simple math and my UltraGauge are both telling me to ignore the fuel gauge. Fear tells me to fixate on the gauge.

Who's run it to fumes? What's your take? Who should I trust?

On 31 March, I took a trip to Big Bear, CA. It is about two hours from my house. To my surprise I got 14.33 mpg. My LX450 has 20" rims. Everything else is stock. Also, I use Archoil 6200 at every fuel fill up.

Twice I've driven back from Moab to the front range in Colorado on one tank, using 22.3 gallons and the second time using 21.5. Adjusting for tire size, I got 16.8mpg over 360 miles the second time. Pretty good for a heavy 80 with a RTT. I drafted the same semi at a safe distance for like 2 hours in Western Colorado until we started climbing up Vail Pass. I kept it at about 65 in the slow lane on the flat parts, and then super gentle on the throttle going up Vail Pass and to the tunnel. To make sure I didn't run out of gas, I just checked how far I had gone half way though the tank. If I made at least 180 miles on the first half of the tank I would probably make it. The fuel light faded on and off for a long time (it turns on earlier on downhills, then turns off when the road levels out), and finally tuned on in earnest maybe 20 miles from the end.

I must be getting way more smiles per gallon because I get way less miles per gallon then most of you.

My normal back and forth to work (70% freeway) is about 10.5. Sadly its about the same as my 6.2L Raptor that has 2x the HP, weighs more and is a foot wider and I drive it faster.
off road is way lower. maybe 150 a tank if I'm lucky.

Smiles per gallon is what really matters anyway!! #SPG

 

[Qball]

averaging 10-11 now and days since I drive it surface street more then freeway.

Did 507 miles on the main tank last weekend on a trip over the Sierras. 25 gallons burned = 20.3 mpg. Speeds up to 75, and flogged it over the passes. 108 degrees going through Sacramento on Sunday with the AC blasting.

My range on the reserve would be around 100 miles. Not really a fair comparison, as I also have a diesel, and always have the 13 gallons in the sub. I was lucky to get 12 mpg with the gasser; so one would expect 50 miles to be a safe distance for those running gasoline.

Man, I can't match that mileage I usually get 17-19 mpg on my non intercooled, g turbod 1hdt with an auto a442f. My highest was 19.5 and lowest was 16ish. Are you running stock air box and fuel pin? (I heard that Torfab makes both and they can yield an mpg or 2)

Clearly it’s the super swanky vinyl wrap that’s killing your mileage. On the flip side, nodody’s going to mistake your for @LandCruiserPhil

 

[danthman114]

14.5 ish. when my trip meter hits 200, no light yet but I should look for a gas pump...

 

[FJP971]

8.5-10.5mpg. 35" tires, 2.5" suspension lift, 1" body lift, dual swingout with 35" spare, drawers full of stuff. Seems to run rich. Need to figure out why... I only drive 10 miles to and from work so I'm in open loop a lot of my drive.

How do folks figure out how much fuel to carry with them off-road? I have never been on any 3-4 day outing in the mountains or rock climbing or anything, so in order to eventually be prepared for it, how do I figure?

We recently took a trip on a VERY LIGHT wheeling trail (it was more like driving on gravel roads at 35-40 MPH) and I was actually surprised at how little fuel I used during that part of the trip. I used more getting to and from than I did in the middle of it. Even though it's figured "per mile", has anyone ever figured gallons per hour during wheeling time? Because your actual travel distance can be low.

Also, do you shut it off between sections? As I watch the videos, I see groups of people parked and watching everyone else come up (or down) a section. Are everyone's trucks shut off during this time?

I once let my truck idle for 6.5 hours with the AC on. It used 11 gallons of fuel (I forgot to shut it off before I was lifted on top of a structure where I had to be until the project was finished and they could let us back down with the crane) It was NICE AND COLD inside when I got down. It was so hot and humid outside that ALL of my windows had condensation on the OUTSIDE of them. My truck looked like a nice cold beer!

I brim just before leaving tarmac, and carry 2 x 20 litres on the rack as well. It is unlikely I would not get back to civalisation due to fuel used during the journey. For me it is about a breakdown, or a known trail has been unexpectedly blocked by a washout or rock fall, so hopefully having enough to turn and get back out, and of course there is always the punctured fuel tank scenario.

13.9 mpg, from bay area up over donner to reno with a heavy right foot

 

[davesax36]

I just got 7.4 MPG on my last tank, but I probably have a bad coolant temp sensor and a vacuum leaking brake booster. Hopefully after Ryan is done with it, I'll be able to get 14-16 on the highway.
