If you have been eyeing a new LandCruiser 70 Series, there is a new fluid to add to your pre-trip checklist. From the 2026 model year, every variant in the 70 Series lineup, from the single cab-chassis workhorse to the 78 Series Troopcarrier, arrives with a 20-litre AdBlue tank as standard. It is 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 is a plain-English breakdown of what that means for everyday ownership.
The good news upfront: engine outputs are completely unchanged. The 70 Series diesel still delivers 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 performance character that made the 70 Series a legend on and off the bitumen is entirely intact.
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 Is AdBlue and How Does It Work?
AdBlue is a precisely formulated solution of urea and deionised water. It is stored in a separate tank and injected into the exhaust stream downstream of the engine. There, it triggers a chemical reaction inside the selective catalytic reduction (SCR) converter, breaking harmful nitrogen oxide (NOx) molecules down into harmless nitrogen and water vapour. The result is a dramatic reduction in tailpipe NOx, which is the core requirement of the Euro VI standards now mandated under ADR 80/04 for new vehicles in Australia.
It is worth understanding that AdBlue never enters the engine or mixes with diesel. The two systems are completely separate, which is why the performance figures are unaffected. Confusing the two fill points, however, can cause serious and expensive damage, so always check the cap before you pour anything.
Where Is the Refill Port on the 70 Series?
Toyota has positioned the AdBlue filler in a sensible, accessible spot, though it does vary by body style. On the 76 Series wagon, 78 Series Troopcarrier and 79 Series double cab, the port is located above the front left fender and features a lockable key lid. On the single cab-chassis variants, it sits on the left side of the vehicle between the cab and the rear wheels. Either way, the cap is colour-coded blue as per industry convention, making it easy to identify at a glance.
Running Costs and Consumption: What to Expect
AdBlue is widely available at service stations around the country, both at the bowser and in sealed containers for stowing in the vehicle. Consumption varies with load, terrain and driving style. As a general industry guide, diesel vehicles commonly use a few litres of AdBlue per 1,000km, though your actual figure will depend on how and where you drive the 70 Series. Toyota will publish model-specific consumption data through its official channels.
The most important operational rule is straightforward: do not let the tank run dry. Unlike running low on fuel, which allows a restart once you refuel, an empty AdBlue tank will prevent the engine from restarting by design. This is a regulatory requirement built into the system, not a manufacturer quirk. For owners planning remote touring, factoring in AdBlue availability alongside fuel range planning is now part of the pre-trip routine. Carrying a spare container of AdBlue in the rear is a sensible precaution anywhere beyond the main highway network.
The Troopcarrier Trade-Off
The packaging of the SCR system has required one notable compromise. The 78 Series Troopcarrier's main fuel tank has been reduced from 180 litres to 130 litres to make room for the AdBlue components. That is a meaningful reduction for a vehicle known for serious long-range capability, and prospective buyers planning extended outback trips will want to factor this into their range calculations and auxiliary fuel strategies. Other variants in the lineup have not seen equivalent fuel tank changes. You can read more about the broader MY26 changes in our dedicated 70 Series AdBlue overview.
A New Normal for Working 4WDs
AdBlue is already familiar to owners of European trucks, vans and a growing number of passenger vehicles, so the infrastructure and products are well established. The 70 Series joining this ecosystem is simply the next step as Australian emissions standards align more closely with global benchmarks. If you are curious about how this shift is affecting the collector appeal of pre-ADR 80/04 V8 models, our piece on LandCruiser 70 Series V8 collectible values is worth a read.
For most owners, the day-to-day reality of running a landcruiser adblue system will be minimal: 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. The 70 Series remains as capable and purposeful as ever, with a cleaner footprint to match.
