From the 2026 model year, every new LandCruiser 70 Series arrives with a 20-litre AdBlue tank as standard, from the single cab-chassis workhorse to the 78 Series Troopcarrier. It's part of Toyota's compliance with ADR 80/04, the Australian Design Rule that brings Euro VI emissions standards to all applicable new vehicles sold from 1 November 2025. Here's what that adds to your pre-trip checklist.
Engine outputs don't change. The 70 Series diesel still makes 150kW at 3,000 to 3,400rpm and 500Nm between 1,600 and 2,800rpm on automatic variants. AdBlue works alongside the engine, not inside it, so the way your 70 Series drives on and off the bitumen stays the same.
At a Glance
- Every MY26 LandCruiser 70 Series has a 20-litre AdBlue tank as standard.
- AdBlue is a urea-and-water solution that cuts nitrogen oxide (NOx) emissions via selective catalytic reduction (SCR), required for ADR 80/04 compliance.
- The refill port sits above the front left fender on the 76, 78 and 79 double cab; on the single cab-chassis it is located on the left side between the cab and rear wheels.
- Running the tank dry prevents the engine from restarting by design, so topping up before remote trips is essential.
- The 78 Series Troopcarrier's fuel tank has been reduced from 180 litres to 130 litres to accommodate the new system.
What AdBlue is and how it works
AdBlue is a precisely formulated solution of urea and deionised water. It sits in its own tank and gets injected into the exhaust stream downstream of the engine.
There it triggers a chemical reaction inside the selective catalytic reduction (SCR) converter, breaking nitrogen oxide (NOx) molecules down into nitrogen and water vapour. That drop in tailpipe NOx is the core requirement of the Euro VI standards now mandated under ADR 80/04 for new vehicles in Australia.
AdBlue never enters the engine or mixes with your diesel. The two systems are separate, which is why the outputs don't move. Mix up the two fill points and you can do serious, expensive damage, so check the cap before you pour anything.
Where the refill port sits on the 70 Series
The filler is easy to reach, but it moves with the body style. On the 76 Series wagon, 78 Series Troopcarrier and 79 Series double cab, the port sits above the front left fender with a lockable key lid. On the single cab-chassis it sits on the left side between the cab and the rear wheels. The cap is colour-coded blue either way, so you can pick it at a glance.
What it costs to run and how much you'll use
You can buy AdBlue at service stations around the country, at the bowser and in sealed containers you can stow in the vehicle. Consumption shifts with load, terrain and how you drive. As a general industry guide, diesel vehicles commonly use a few litres of AdBlue per 1,000km, though your figure depends on how and where you drive the 70 Series. Toyota will publish model-specific consumption data through its official channels.
The one rule that matters: don't let the tank run dry. Run low on fuel and you can restart once you refuel, but an empty AdBlue tank stops the engine restarting by design. That's a regulatory requirement built into the system, not a manufacturer quirk. If you're touring remote, AdBlue availability now sits alongside fuel range in your planning. Carry a spare container in the back anywhere beyond the main highway network.
The Troopcarrier trade-off
Packaging the SCR system cost the Troopcarrier some fuel. The 78 Series Troopcarrier's main fuel tank drops from 180 litres to 130 litres to make room for the AdBlue components.
That's a real cut for a vehicle built on long-range capability, so work it into your range figures and your auxiliary fuel plan before an extended outback trip. Other variants in the lineup haven't seen equivalent fuel tank changes. For the wider MY26 picture, read our 70 Series AdBlue overview.
MY26 ordering: automatics are back, manuals aren't
The AdBlue change is why the automatic 70 Series dropped off order books through 2025. Toyota Australia has since reopened automatic orders across the 76 Series wagon, 78 Series Troop Carrier and 79 Series cab chassis, with the emissions hardware now sorted. The five speed manual is still unavailable on the 76 Series GXL wagon, the 78 Series Troop Carrier and the 79 Series double cab chassis, so three pedal buyers are still waiting.
Engine outputs through the six speed automatic are unchanged at 150kW and 500Nm, and manual variants stay rated at 450Nm. The MY26 update is an emissions update, not a cabin update: the interior is the same working grade cabin the 70 Series has worn since the 2023 facelift, so the current PVS interior range carries straight over to a new MY26 build.
The new normal for working 4WDs
Owners of European commercial vehicles, vans and a growing number of passenger vehicles have run AdBlue for years, so the products and infrastructure are well established. The 70 Series joining that ecosystem is the next step as Australian emissions standards line up with global benchmarks. If you want to know what this shift is doing to the collector appeal of pre-ADR 80/04 V8 models, see our piece on LandCruiser 70 Series V8 collectible values.
Day to day, running a landcruiser adblue system asks little of you: check the level at each service or long-distance fuel stop, keep a spare litre or two aboard on remote trips, and never mix the fill points. Your 70 Series still does the same work, with less NOx out the back.
