Japanese figures are the official 10-15 mode test, as listed on Carsensor ↗ catalog pages (1 km/L = 2.352 US mpg). A lab test is kinder than the road, so expect less. Wikipedia’s “Kei truck” article only says kei trucks are claimed to get 40 mpg.

Where do these mpg numbers come from?
Who says what
We show who reports each number, and no single exact mpg as fact.
- Makers
- Suzuki, Honda, Daihatsu, Subaru and Mitsubishi never rated these trucks in US mpg, as far as we found.
- Japanese catalogs
- Test figures for the Carry and Hijet, as above. Carsensor lists the same range for every Honda Acty generation, so our data marks it unreliable, and it had no page we could read for the Sambar and Minicab.
- Wikipedia
- The kei truck article ↗ says kei trucks are claimed to get 40 mpg (17 km/L), without naming a model or a year.
- Owners
- About 34 mpg for a Carry, and about 35 mpg for an Acty, with one Acty owner measuring 35 to 41 mpg on a 65 mph highway trip. The owner reports are quoted on the Carry and Acty pages.
Are kei trucks fuel injected?
Carburetor or fuel injection varies by year and trim.
- Honda Acty, 1988–99Carburetor; fuel injection added to the 656 cc engine in 1996.Mostly carb
- Mitsubishi Minicab, 1991–99Carburetor on the base trucks; fuel injection on higher trims from 1997.Mostly carb
- Daihatsu Hijet, 1994–99Fuel injection on automatics and optional on manuals; carburetor versions exist.Mixed
- Subaru Sambar, 1999–2012All fuel-injected: single-point at launch, multi-point from Aug. 2001.Injected
- Suzuki Carry, 1999–2013Turbo versions are fuel-injected. We found nothing stated for the naturally aspirated ones.Turbo: injected
From each model’s Wikipedia article. Check the exact truck: ask the seller or look under the hood.
How many gallons does a kei truck hold?
The fuel tank.
How big is a kei truck’s fuel tank?
We found no tank size from a maker or a reliable source for any of the five trucks, so we give none. Ask the seller, or look it up for the exact model and year. Do not use a gallon figure from a different year or a different country’s version.
Kei truck gas mileage: questions
How many mpg do kei trucks get?
Japanese test figures put the older Suzuki Carry at about 34 to 40 mpg and the Daihatsu Hijet at about 33 to 40. Owners report about 34 mpg for a Carry and about 35 for an Acty. Real driving is lower, especially at highway speed.
Are kei trucks fuel efficient?
Next to a full-size pickup, yes. At 35 mpg and 4.15 dollars a gallon, 100 miles a week costs about $51 a month in gas, against about $90 for a Ford F-150 at its EPA 20 mpg. They are slow, so they are best on short, slow trips.
Do kei trucks have fuel injection?
It depends on the year and trim. The Honda Acty’s 656 cc engine got fuel injection in 1996, the Subaru Sambar from 1999 to 2012 is fuel-injected, the Daihatsu Hijet has it on automatics, and the base 1990s Minicab and the early Acty are carbureted. Check the exact truck.
What gas do kei trucks use?
They are small gasoline engines of 660 cc or less. We found no sourced octane rating, so check the fuel cap label or the manual, or ask the seller.
How big is a kei truck’s gas tank?
We found no sourced tank size for these trucks, so we give none. Ask the seller or check the exact model and year.
Is the Subaru Sambar or Mitsubishi Minicab better on gas?
We found no mpg figure we trust for either, so we cannot say.
Where these figures come from
What we did: read the Japanese catalog fuel-economy figures in our data (Carsensor, checked Nov. 9, 2026), the Wikipedia articles on kei trucks and the five models, the owner reports linked on our Carry and Acty pages, the EPA figure for the F-150, and the EIA gas price, all on Nov. 7 to 10, 2026.
What this does not cover: any measured mpg (we did not test a truck), maker brochures, the Sambar and Minicab, the Hijet before 1999, fuel tank sizes, octane ratings, and differences between versions. The Honda Acty’s Japanese catalog range is the same for every generation, so we do not use it. General information, not buying advice.
