Gas MPG

    I've tracked my gas mileage on my 1992 Carry 5spd several times since it's my main vehicle. Gas quality is very important and head winds are killer too..

    I'm getting a basic average of 40 MPG. Sometimes it's 39 MPG, sometimes it's 41 MPG. Lowest has been like 32 MPG on some crap gas... I track the KM between fillups and then convert to miles and divide
    I run 90 KPH ( 55 MPH ) on a main highway ( not interstate ) 44 miles to work and back at least 3 times a week. Sometimes I car pool or it would be more..
    As for the gas I run, I just put 87 octane 10% ethanol in it. Sources tell me ethanol fuel is in Japan too and I DD this and with a 7 gallon tank, fuel is always fresh. The one time I put non ethanol premium in it the gas was bad in the station and the little 660cc could barely handle it

    are you running factory diamater tires?

    Mines a 4x4 and I have 145 R12 Yokohama tires. 372S IIRC, they are the ones that are DOT legal

    185 70 13" and I go by GPS for my distance!

    That's the one thing I have not done so I don't know exactly if the old cable speedo is totally accurate. Factory tire size on the factory rims though so should be close.

    Typically I hold 1/4- 1/2 throttle to maintain 55. Truck probably has a lot more in it but I don't push it past 55 unless it creeps up there on it's own. Can tell that between 50-55 MPH is the engines sweet spot with the 12" tires.

    I run about 55 60 mostly, but I really need the carb done and timing belt and water pump as well as cap, rotor and plugs!

    I could probably use everything except the carb. My truck runs great. Starts on 3rd crank, solid idle. It seems a slight bit rich due to the elevation differences from Japan to here but I'm afraid to touch it.. My truck has a timing belt change sticker but it's wiped or was never marked. So it's been done, sometime.. Not sure about the cap and rotor because it runs really good but it is something I normally do to used vehicles... I checked the fluids, changed the oil, put the DOT rated tires on and started driving it.

    The best I have done in my 1991 5-speed 4wd carry is 32mpg on mostly 50-55mph highway. strictly 25-35mph in town driving the worst I have gotten is 24mpg. with a mix I get about 28mpg. the area I live in has a lot of hills and a lot of stopping. I run 87 speedway gas. My truck is all stock with the Japanese highway tread 145R12LT tires. I cleaned the carb out, new cap, new rotor, synthetic oil. the rest of the truck is untouched.

    That's about where Im at!
    I have 13" tires and need the carb done and had hopes of 30 around here and hopefully like 35 on the road?

    I've noticed it can be very dependent on what gas I use. A couple times I filled up at stations I don't like to use, but with a small tank, I get gas where I can if it's under 1/4 tank. Fuel mileage those times was horrible..

    My route is fairly flat with a bit of down hill. one hill to climb about 1/2 mile going to work with 3-4 miles of downhill , and that is reversed going home. Trip is 44 miles each way.. It's still continually in that 39-40 MPG range on average.

    Are you using the odometer or GPS?
    I have both and with the 13" tires my Od is off!

    I mainly use the odometer but have checked it with a GPS and it's pretty accurate. Since I run the factory 145R12 just in a DOT legal tire. that's probably why it's a non issue.

    i travelled 350KM using 27.10 litres of fuel in my newly aquired Sambar, bear in mind about 200KM of that was a full load with family and camping gear. that means if my calculations are correct i'm getting 36.5 MPG.
    not bad for a 20 year old van

    wow you guys get some really good MPG out of these....

    im always in 4wd & half the time in low range on my hillsides. & my mini spends a lot of time at high idle when im using the sprayer & so on.

    used half tank of gas in the last month & only put 40 miles on it. that would put me in the 10-12pmg range. :)

    I get 22-mpg. But I’m mostly putting around town and can’t get past third gear due to speed limits.

    When, I’m not in town, I’m in 4wd, low range, playing in the woods. I’ve never even thought of trying to calculate the fuel economy when I’m doing that. I have two Rotopax, 4-gallon gas cans I take with, and whenI run low enough it starts to sputter, I top off and head for the house.

    I believe my Suzuki only has an 8 gal tank?
    I would like to double that for better range.
    My Isuzu 5ton has a 110gal fuel tank and my VW has 16 but gets over 40mpg!

    What are the benefits to that?
    More power?
    Better millage?
