    4wd members with All/Mud Terrains: Whatís your MPG like?

    Iím just curious to see how many miles per tank other members are getting with big tires. Iím getting about 210 miles before my low fuel light turns on despite how/what type of driving I do. Also this is with AC on 100% of the time.

    That seems like great milage - another question is... does someone know the size of the fuel tank? My gauge doesn't work, so I'm filling up pretty early I suspect (usually around the 170 mark) - getting between 17-20 mpgs with All terrains depending on driving conditions.

    I think tank size is in the 14-15 gallon range. The most I have put in is 13.5 gallons, and I was holding my breath all the way to the gas station.

    The best I have gotten is 27mpg (lifted with all terrains). I usually average between 24-26 for my daily driving. My van is a diesel, so it gets a bit better mileage than the gas versions. I also don't have A/C, so that helps a bit as well.

    Fuel tank capacity for the US vans is 15.9 gallons. Both my vans would go 200-250 before I see the light on steady and I will try to get fuel in the next 20 miles though I have on occasion pushed to 300 miles. Both vans are running LT27x8.50r14 all terrains with auto transmissions. Keep in mind that this tire size has a larger rolling diameter than stock and the odometer and speedometer likely are not accurate.

    So what is the general milage on these things with AT's on them? I am putting some general grabbers~27x8.5x14's on mine... was hoping to stay around the 20mpg mark. Doesn't look like that may happen.

    I just got a tad over 20mpg with 27x8.5x14 grabbers on a freeway trip. My a/c isn't working at the moment

    Same here. Roughly 25mpg on 2CT 4WD running Maxxis Bighorn MT-762 LT27x8.50R14.

    Re: 4wd members with All/Mud Terrains: Whatís your MPG like?

    On 8/31/2020 I upgraded to General Grabber 27x8.5 R14 LT. 1987 Van MT 4x4 (no AC) in Washington State.

    Since upgrading, I've been averaging 15.95 MPG combined: 13.81 in the City, 18.69 in Rural mostly flat highway driving, and 16.23 when driving over Stevens Pass (highway over Cascade mountain range: approx 4,000' elev difference).

    98% has been 2WD up til this point but snow's around the corner so I can update once the roads get slick!

    Unfortunately I wasn't keeping track of gas mileage beforehand; would have been nice to see any change from tire size.

    MPG seems low by comparison (especially around town; relatively flat but lots of stoplights and idle time). Open to ideas on where to look or how to start improving gas mileage?!?!

    Since buying the van in August, have installed a re-cored radiator/water pump/thermostat/hoses, new battery/starter/alternator/idler pulley/belts, new transmission/transfer/differential & engine oil. Buttoning up general maintenance & upgrades (windows, locks, heaters, windshield wiper pumps, wiper motors, air filters) to make it more reliable as a daily driver. Taking a course on engine rebuilding and making wiring harnesses from scratch but up til this stage not too familiar with fuel injection systems. Any input appreciated!

    Found another post that answers my question pretty well on where to start looking for improving fuel efficiency:
