Hyjet Gas mileage?????

[jsmikle]

What are you all getting for gas mileage in your hyjet diatsu??? I got a 95 with a 5 speed shift on the fly 4 wheel and got 20.4 miles to the gallon. I use this as a daily commuter to the rand and to home cause in south dakota you can license them. It is runned down the highway so it is rapping fairly high rpms i would say and there was about half of the miles in four wheel drive. In the articles about these they say 40 to 50 mpg!!!! That is why I got one but only 20mpg is not bad but it is no 50mpg!!!!!!!!!!!! Wondering if anybody is getting better??? I am converting this to mpg not kliks i wonder if it ain't 40-50 kliks per gallon. 20.4 mpg is 34 kliks per gallon Thanks JON

I found better mileage at slower speeds 40-45mph. The speed limits in Japan are lower and these are designed for that. 65 in a kei would be somewhat like 90 -100 in an american vehicle. Larger than stock tires will also lower mileage. I got 30 last summer doing the irrigating. 30 miles 2x a day and over half on gravel roads.

I'm averaging 30 to 32 mpg on mine, keeping to a top speed of 55. 40 to 50 mpg simply isn't gonna happen with our trucks, period.

these trucks weigh the same as a geo metro. over the years i've had 10 of the little buggers. they all got 40 mpg , some had 1,000 cc 3 cylinder , some 1,300 4 cylinder, 2 valves or 4 valves , automatic , 4 speed or 5 speed OD .
the only time i ever saw much difference was pulling a load ( a 8 ft trailer with 5 space walks & fans in it 1200 lbs) then the larger motors much better mileage .
i found that tires even 1 inch taller killed the mileage and power on the smaller motors . but a 1 inch shorter tire 175/50r13 helped the power with no change in mileage.
that said ;my Midget II got about 40 on it's last tank . it is 2WD, lighter and has less frontal area, but the same motor . i've added a 2 inch exhaust w/ turbo muffler ( it never had a cat) fresh air intake , turned the timing up 4 degrees and run 93 octane gas.
next step will be an od transmission. hoping for 45!

I have a 1995 Hijet 5 speed and the best I have mileage I have gotten is 15.8 town and 28.4 highway. I am have the carb rejetted and hope maybe for 30 mpg. This 40 to 50 mpg is a joke and if I can't get 30 I am going to sell this little thing.
