Real World Pajero Fuel Consumption by Generation

Mitsubishi quoted 9.0 litres per 100km for the late Gen 4 3.2 DiD. Ask anyone who owns one what they see on a tank and you get a different answer.

Real Pajero fuel consumption sits above the brochure, and the gap depends on which engine you bought and how you use it. Spritmonitor logs 351 diesel Pajeros across 19 565 fuel ups. The average comes out at 11.10 litres per 100km, 5.9 percent above the catalogue figures for those cars. The petrol cars do worse. Ninety five vehicles, 4 960 fuel ups, 13.56 litres per 100km, 12.1 percent above claimed.

Below are the honest numbers by generation and engine, where each came from, what each type of driving costs, and what a Johannesburg to Cape Town run works out to in rand at August 2026 prices.

Why the brochure number was never going to happen

Old Pajeros carry NEDC laboratory figures. That test runs on a rolling road with gentle acceleration, no aircon, no roof rack, no load and a top speed most South Africans exceed on the on ramp. It was never a prediction of your week.

The gap is consistent enough to work with. Auto ABC, which compares factory claims against owner reported consumption, shows Pajero petrols about 13 percent over claimed and diesels about 14 percent over. Treat the brochure as a floor. Add 10 to 16 percent, then add more for everything you bolted on.

Claimed versus real world by generation and engine

Generation and engine	Claimed combined	Real world	Gap	Where the real number came from
Gen 1 2.5 TD (4D56), 1982 to 1991	10.8	Too few logged cars to quote	n/a	No usable dataset
Gen 2 2.5 TD	Not published consistently	9.93	n/a	One 1992 car, 2 437 km, Spritmonitor
Gen 2 2.8 TD (4M40)	12.3 to 12.4	13.1	plus 6 percent	Auto ABC
Gen 2 3.0 and 3.5 V6 petrol	13.9 for the 3.0, no combined published for the 3.5	No clean aggregate	n/a	Auto Data
Gen 3 3.2 DiD manual	9.1	10.0	plus 10 percent	Auto ABC
Gen 3 3.2 DiD automatic	9.5 to 10.1	11.2	plus 11 percent	Auto ABC
Gen 3 3.5 V6 GDI	12.8 to 14.2	15.7	plus 11 percent	Auto ABC
Gen 3 3.8 V6, 2003 on	SA listings show 16.15 to 17.79	No clean aggregate	n/a	Car Specs SA
Gen 4 early 3.2 DiD, 2006 to 2009	10.6	11.9	plus 12 percent	Auto ABC
Gen 4 late 3.2 DiD, 147 kW	9.0 to 9.3, SA brochure 10.1	10.8, and 11.41 on one 2013 car	plus 16 percent	Auto ABC, Spritmonitor over 54 801 km
Gen 4 3.8 V6 MIVEC	13.5, SA brochure 14.1	15.1 to 15.2	plus 13 percent	Auto ABC, Spritmonitor over 19 076 km

Two things stand out. The late 147 kW diesel shows the widest gap in the range, because Mitsubishi chased a tightening test cycle while the car itself got heavier. And the Gen 3 diesel, lighter by roughly 265 kg, genuinely beats the Gen 4 in the real world. Both are covered in the Gen 3 buyers guide and the Gen 4 buyers guide.

What each type of driving actually costs

Combined figures hide everything useful. Here is the split, based on measured tests and owner logs rather than brochures.

Town driving. CarsGuide recorded 9.5 litres per 100km over 150 km of city and suburban running in a 2018 Pajero GLS diesel against a 9.1 claim. That is light traffic. Add Joburg peak hour crawling, a cold engine every leg and the aircon on, and 12 to 13 is normal for a 3.2 DiD. The 3.8 V6 sits around 17 to 18.

Highway at 120 km per hour. This is where South Africans burn most of their fuel and where the brochure lies hardest. Oak Ridge National Laboratory tested 74 light vehicles and found fuel economy at 129 km per hour runs about 27 percent worse than at 97, with the optimum between 64 and 80. Apply that curve to a 3.2 DiD returning 9.5 at a steady 100 and you land near 11.5 at a true 120. A 2.2 tonne brick is the wrong shape to argue with air.

Gravel touring. CAR magazine ran a Pajero SWB 3.2 DiD Legend II over a weekend that included Atlantis dune work and hovered around 10.5 litres per 100km. CarsGuide’s mixed 329 km loop of highway, back roads, gravel and low speed four wheel drive returned 11.08. Call it 11 to 12 for a loaded Karoo or Kalahari gravel trip in a diesel at sensible speeds.

Low range work. Verified numbers are thin and anyone quoting a precise figure is guessing. The one solid South African data point comes from the Pajero Owners Club of South Africa, where V6 petrol owners report 4 km per litre in normal sand and 3 km per litre when it turns difficult. That is 25 to 33 litres per 100km. The diesel sits below that, but no verified diesel sand figure exists. Plan your range on the petrol numbers and you will never be stranded.

Towing. Owner reports on Pat Callinan’s 4X4 Adventures put a 3.2 diesel at over 20 litres per 100km pulling a 2.6 tonne loaded caravan, and around 14.5 with a full size van behind a lighter Challenger. Anything above two tonnes on the ball roughly doubles your highway consumption.

What actually changes the number

Owners argue about this constantly. Here is what the measurements support.

Speed. The biggest lever you control. About 27 percent worse at 129 km per hour than at 97, per the Oak Ridge data. Dropping from 130 to 110 on the N1 saves more than every modification below combined.
Driving style. Hard acceleration and late braking cost 15 to 30 percent at highway speeds and 10 to 40 percent in stop start traffic, per the US Department of Energy.
Weight. Roughly 1 percent per 45 kg, so about 2 percent per 100 kg. Drawers, a second battery, a fridge, full water and recovery gear add 150 to 250 kg easily. That is 3 to 5 percent before you move.
Roof racks and rooftop tents. The worst offender. Roof mounted cargo cuts fuel economy by 2 to 8 percent in town, 6 to 17 percent on the highway and 10 to 25 percent at sustained high speed. Lawrence Berkeley National Laboratory measured 0 to 25 percent depending on setup, and found empty racks left on all year do more national damage than loaded ones because nobody removes them. A rooftop tent is a permanent loaded rack, so expect the top of that range on the N1. A rear mounted carrier costs only 1 to 2 percent in town and 1 to 5 percent on the highway.
Tyre size. This costs more than owners expect, and part of it hides from you. Moving a Gen 4 from 265/65R17 to 265/70R17 grows rolling circumference 3.4 percent. Going to 285/70R17 grows it 7.0 percent. Your trip meter under reads by the same amount, so your calculated consumption flatters you while real consumption climbs. Add unsprung weight and taller effective gearing and a 33 inch tyre on a 3.2 DiD costs a real litre per 100km.
Tyre type and pressure. Aggressive all terrain tread costs up to 3 percent against a milder tyre. Underinflation costs about 0.2 percent for every 1 psi below spec across all four tyres. Correct pressures return 0.6 percent on average and up to 3 percent on a neglected set. Running gravel pressures home on tar is quietly expensive.
Lift kits. No controlled Pajero test exists. A 50 mm lift raises frontal area and disturbs airflow under the body. Owners who lift, retyre and rack in one weekend report 1.5 to 2 litres per 100km worse afterwards, then blame the lift when most of it came from the tyres and the rack.
Air conditioning in Kalahari heat. In very hot conditions compressor load cuts fuel economy by more than 25 percent, worst on short trips. On a long cruise the penalty is far smaller. Do not open the windows instead at 120. That trade goes the wrong way above about 80 km per hour.
Altitude. A naturally aspirated engine loses roughly 3 percent of its power per 1 000 feet, or 305 metres. Johannesburg sits at 1 753 metres, so a Gen 2 3.0 V6 gives up close to 17 percent of its output on the Highveld. You claw that back with throttle, and throttle costs fuel. The turbo diesel barely notices because it compresses the thin air back up.
Condition. The blocked air filter myth is overstated. On modern fuel injected engines a fresh filter improves acceleration but does not restore fuel economy. Worn injectors and EGR and intake carbon do cost you, though nobody publishes a clean percentage. One study measured close to 10 percent power lost to carbon in under 16 000 km. A dragging brake costs over 1.5 percent when it drags a quarter of the time, per Bendix SAE J1321 testing. If consumption climbed two litres with no change in how you drive, work through injectors, intake carbon and brakes in that order. Our 3.2 DiD common problems guide covers the symptoms.

What it costs you in rand

South African fuel prices changed on 5 August 2026. Inland, 95 unleaded costs R25.58 per litre and 93 costs R25.42. Diesel is not price controlled at the pump, so government publishes a wholesale reference instead, and that sits at R26.40 per litre for 50ppm inland and R26.16 for 500ppm. Coastal is cheaper at R24.71 for 95 and R25.53 for 50ppm diesel.

Every diesel figure below uses the R26.40 reference. Your pump charges more, so treat these as a floor.

Johannesburg to Cape Town, 1 400 km on the N1.

Vehicle and condition	Litres per 100km	Fuel used	Cost
3.2 DiD, unloaded, sensible speed	10.5	147 litres	R3 881
3.2 DiD, loaded with roof tent at 120	12.5	175 litres	R4 620
3.8 V6, unloaded	14.0	196 litres	R5 014
3.8 V6, loaded with roof tent at 120	16.0	224 litres	R5 730

The roof tent and the extra 20 km per hour cost a diesel owner R739 one way, so R1 478 there and back.

A month of commuting. Sixty kilometres a day, twenty days, so 1 200 km of town driving. A 3.2 DiD at 12.5 uses 150 litres and costs R3 960. A 3.8 V6 at 17.5 uses 210 litres and costs R5 372. That is R1 412 a month, every month, for the same journey.

A year, 25 000 km mixed. The 3.2 DiD at a realistic 11.0 burns 2 750 litres and costs R72 600. The 3.8 V6 at 15.2 burns 3 800 litres and costs R97 204. The V6 costs R24 604 more a year in fuel alone, which is why the purchase discount on a cheap 3800i evaporates inside four years. Run the rest of the sums in our cost of ownership guide.

Frequently asked questions

What should a 3.2 DiD actually return?

A Gen 3 sits around 11.2 in mixed use. An early Gen 4 sits around 11.9. A late 147 kW Gen 4 sits around 10.8 to 11.4. Loaded and towing, all of them climb into the teens. If yours reads 14 in normal mixed driving, something is wrong.

Why does mine use more than the brochure?

The brochure came from a laboratory cycle with no load, no accessories, no aircon and a gentle throttle. Then your roof rack, your all terrain tyres and your right foot add their own share on top.

Is the 3.8 V6 really that much thirstier?

Yes. Owner logged data puts it at 15.1 to 15.2 litres per 100km against 13.5 claimed. Over 25 000 km a year that is roughly R24 600 more than a 3.2 DiD. It is smoother, quieter and cheaper to buy. It is not cheaper to own.

How far will a tank take me?

A Gen 4 carries 88 litres. At 11.0 that is 800 km theoretical, so plan a fill at 650 to 700. The 3.8 V6 at 15.2 covers about 578 km. Gen 3 long wheelbase cars carry 90 litres. Check your exact model on the Pajero specs page before a Kalahari run.

Do bigger tyres really cost fuel?

Yes, and they lie to you while doing it. A jump from 265/65R17 to 285/70R17 grows rolling circumference by 7.0 percent, so your trip meter under reads by 7 percent and your calculated consumption looks better than it is. Add weight, tread pattern and effective gearing and you pay about a litre per 100km for the look.

The short version

Add 10 to 16 percent to whatever the brochure claims. A 3.2 DiD returns 10.8 to 11.9 litres per 100km in mixed use depending on generation. A 3.8 V6 returns 15.1 to 15.2. Speed matters more than any modification, costing about 27 percent between 97 and 129 km per hour. A roof tent costs 10 to 25 percent at highway speed. Bigger tyres cost roughly a litre per 100km and hide part of it behind an under reading trip meter. At August 2026 inland prices a Joburg to Cape Town run costs a diesel owner R3 881 unloaded and R4 620 loaded.
