The Gifu's interior.

The Gifu is a dirty and worn vacuum truck that the player owns after Uncle Kesseli gives you it. The player can use it for septic tank pumping jobs. It has a 6x2 taglift chassis with a worn 14L turbocharged diesel engine that produces 390 hp and a myriad of fumes. It is also equipped with some accessories, such as beacons, a sun visor that reads "Suomi Finland," some Gifu branded front mud flaps and a fully functional sleeper cabin. At the start of the game, it's located at the waste processing plant. Before you are able to drive the Gifu and receive septic job calls, you must get the keys from Uncle Kesseli after he loses his license.

The truck's speedometer also has a clock. This is because the speedometer is based on an analog tachograph that logs speed, distance and driver's activities on a round chart. The chart is not accessible in the game.

The truck has an extremely poor fuel economy because of its old and inefficient engine. It is expensive and time consuming to refuel it (≈1,350 mk from an empty tank using diesel and ≈20 real-time minutes of waiting). Consider carrying the diesel canister inside the cabin in case of emergencies.

WARNING: Never downshift the truck from High gear to Low gear unless you are below about 25 km/h! This runs a high risk of blowing the truck's engine, rendering it permanently unusable. If you range down by accident and find yourself unable to start the engine, try to put the hand-throttle all the way to max and the engine should start.


The Gifu is based on a Finnish Sisu M-series truck (specifically an M-162 from the year 1970), and the name references the logo design of the Finnish Sisu candy. The Sisu candy typeface uses old Fraktur, the capital and lowercase S letters of which look like a G and an f to readers of the modern Latin alphabet.

The engine in the game is based on the 405 horsepower 14L Cummins NTE-400 as suggested by the Steam trading card; however, it creates a noise similar to the 12,200cc Rolls-Royce Eagle 320. Both of these were available for Sisu M-161 trucks at the time.

Special functions[]

The truck has several switches and levers on the dashboard that control different functions, some of which are unique to the Gifu.

Differential lock[]

Lock/unlocks the differential, which will force the drive wheels on either side to spin at the same speed. Locking the differential is useful for driving off-road or getting unstuck. However, it will also make turning very difficult and increase fuel consumption, so it is advised not to use it for general driving.

Lift rear axle[]

Lifts the rearmost axle up, which increases drivability and fuel economy. Lowering it will increase traction and provide better weight distribution. It is recommended to lower the rear axle while under a heavy load to increase stability, and raise it when empty. By default, the axle is already lifted.

Hydraulic pump[]

Toggles the septic tank pump. The pumping efficiency is based on the RPM of the engine. The higher the RPM, the faster the pump will operate. You can use the hand throttle to increase the RPM while outside the cab.

Hand Throttle[]

Increases engine idle RPM. Works the same way as the Kekmet's hand throttle. Pulling the lever out will increase the idle RPM, pushing it in will decrease it. Useful for maximizing hydraulic pump efficiency.

Operating the truck[]

Switch on the ignition and wait for the red glow plug light (coil symbol) to turn off. Make sure it's in neutral before turning over. Occasionally, the truck may refuse to start. It will idle for less than a second then stall. Make sure you have fuel, then keep trying until it fires up successfully.

The red air pressure light accompanied with a buzzer means the air pressure is low, rendering the brakes ineffective. Build air pressure by revving the engine or using the hand throttle until the buzzer stops. Using the foot brake or parking brake too often will cause air pressure loss and should be used in moderation. The air tanks are fitted with valves that discharge excess air pressure but can cause a low pressure event if the brakes are applied immediately afterward.

The yellow axle lift light means the rear axle is lifted. This reduces fuel consumption and makes handling lighter when the tank is empty. The truck should be driven with the axle raised when the tank is empty. Lower the axle (yellow light off) while hauling sewage to support the heavier load and increase stability. Lifting the axle is useful for hauling cars to Fleetari. Lifting the axle puts more weight on the drive wheels, therefore increasing traction.

The yellow "L" light means the truck is in low range, which is good for low-speed maneuvers and climbing hills. Hit R(by default) to switch between high and low range (this has no effect on pumping or air pressure.)

The Gifu has 12 forward gears, divided by a low and high range. 1L - 6L is the first half, acting like gears 1 - 6. 1H - 6H is the second half, acting like gears 7 - 12. You could shift through all the gears sequentially, or you could skip gears. Starting out should be done in low range, either 1L, or 2L. To save fuel, an effective order to use the gears is going directly from 2L to 1H.

When stuck or driving off-road (e.g. on grass,) the differential can be locked for increased traction, but steering/turning will be more difficult. It is not recommended to lock the differential when driving normally.

H-Shifter Rev Matching[]

This section of the article only applies to those that use a 6-speed gear stick and a non-auto clutch, such as the one used with the Logitech G29.

Rev matching is a technique used to make smooth gear transitions when shifting, it ensures that the vehicle's gearbox avoids any stress-loads and premature wear (i.e., a burnt clutch.) This technique is required to shift the Gifu's unsynchronized transmission while using an H-shifter. To successfully upshift the Gifu, the engine speed must match the wheel speed in order to create a smooth transition. You need to manually match them through effective use of the throttle and shifting at the correct times. It is recommended to start out in 2L, because upshifting from 1L could be difficult. The gears usually run between 1000-1500 Rpm.

Downshifting can only be accomplished at certain speeds if you want to avoid stalling or grinding gears. Most of the time you will have to double-clutch to successfully change to a lower gear, as the area in the rev-range for downshifting is very slim. To double clutch, shift out of the gear you're currently in and into neutral, release the clutch, tap the throttle, re-engage the clutch, and shift into the lower gear. If successful, you will have a smooth gear change. If not, you will not be able to shift into any gear until your wheel-speed is low enough (around 30 km/h). Ensure that your engine speed (RPMs) is low enough (not too low!) before a downshift, or you will not be able to shift back into gear. In real-life circumstances, you can cause serious damage to the gearbox if your downshifts are not smooth.


  • Filling the tank to its 10,000-litre capacity will unlock the "Full of crap" achievement.
  • It has such a heavy flywheel that it can set off when you let go of the gas and shift into gear.
  • Driving the truck causes stress to rise rapidly. It is advised to carry a pack of cigarettes to prevent stress from reaching critical.
  • Operating the truck’s pump will cause the player’s dirtiness to rise very quickly.
  • The plate next to the gear stick reads WAB and it has number code 475714500 stamped on it. The code has one missing number (7) missing at the end, but it is a code of trailer brake valve, made by Wabco.
  • The license plate number, UPT-737, is a reference to a 1990 Finnish television drama series Lentsu[1].
  • The Gifu is one of the 2 vehicles that both the player and AI are able to drive, the other one being the Boat.
  • The rusted front wheel on the Gifu is most likely from Uncle Kesseli's old Gifu, since it is the only rusted wheel on the truck.
  • The oil pressure gauge and voltmeter appear to be broken, as they stay at the minimum readout regardless of what's going on with the vehicle.
  • From the start of a brand new save, the mileage on the truck will be at 400,000 km. This indicates that the truck has been used frequently and is worn, which explains why the truck releases a huge amount of diesel fumes and has such poor fuel economy.
  • You will officially own the truck after Uncle Kesseli gives it to you because you will instantly receive calls from people who need their sewage wells sucked.
  • The Gifu's model year is 1978, as shown on the Drag Slip, even though it is based on a truck from 1970, and owns an engine that's presumably from the year 1981.
    • This might imply the engine that's currently inside the truck was retrofitted from a later model - presumably due to the original powerplant failing - or it might just simply be a developer oversight.
  • The rear bumper of the Gifu seems to be problematic as it can catch itself on things like bumps, which will prevent the rear wheels from touching the ground and render the Gifu completely stuck.
  • The truck has consumed an estimated of at least 3,120,000 liters of diesel (400,000 * 7.8) in its life time. On average it uses 183529 liters of diesel each year (3,120,000 / 17).
  • The player's variant makes slightly less power than highway one. This might be due to the high mileage of the truck or lack of maintenance.
  • The Gifu used to have a higher pitched version of the Bus's engine sounds, which has since been changed in an update on 5 January 2016.
  • Gifu can be used to effectively tow wrecked cars, though the Kekmet is more cost effective.
  • Gifu is one of the few vehicles that can crawl on idle, in gears 1+Low or R+Low.
  • The Gifu Brand is also present in the Finnish-made game INFRA, on Sisu-based trucks seen throughout the game. This is most likely a nod to MSC, as the game features numerous other MSC-related Easter eggs.
  • Gifu is also the name of a Japanese prefecture.
