Utes have been affected substantially by increasing fuel prices, thanks to their large fuel tanks and often thirsty turbo-diesel engines.

Diesel fuel prices have jumped to more than $3 per litre, making filling up a diesel ute more expensive than ever.

CarsGuide has compiled a list of all the diesel dual-cab pick-up utes on sale, calculating the yearly cost of each at $3.07 per litre (the average price in NSW on 31/3/26) over 15,000km.

Isuzu Ute’s D-Max and Mazda BT-50 2.2-litre turbo-diesel variants are the efficiency leaders. The mechanically identical pair of utes cost $3038.02 in fuel in a year, averaging 6.6L/100km.

The Ford Ranger’s single turbo-diesel 2.0-litre is next on the list, averaging 6.9L/100km, which equates to $3177.45 over 15,000km. 

The new mild hybrid Toyota HiLux also has a competitive efficiency figure of 7.1L/100km, which is a little cheaper in fuel than the standard turbo-diesel variants. 

Three-litre variants of the BT-50 and D-Max vary in cost, given fuel consumption fluctuates between 7.1L/100km and 7.8L/100km depending on the variant.

The KGM Musso is one of the thirstiest of the utes, with its up to 9.0L/100km, costing more than $4000 over the course of a year.  The GWM Cannon Alpha diesel was the other ute to exceed the $4000 mark. 

Concluding the list are the gas guzzling full-size American pick-ups, in Ram’s 2500 and the Chevrolet Silverado HD. Both have V8 diesel engines with a capacity of more than 6.0-litres, meaning they cost more than $7000 over the course of a year.
