⚠️ Toyota manufacturer position
Toyota Land Cruiser fuel service is documented in TIS as tank removal or module service depending on generation. Full-size SUV ground clearance usually requires tank drop for complete drain. Warranty excludes fuel contamination.

Misfuel risk Moderate
US Land Cruisers are gasoline-only, so diesel-in-gasoline at a truck lane is the primary misfuel scenario. Dual-tank models require draining both cells and verifying transfer valve position.
If the engine was not started
Do not start the engine. Drain both tank sections if dual-tank; do not rely on filler-neck extraction due to anti-siphon devices.
If the engine was started
Running on wrong fuel may require fuel rail and injector service, new filters, and tank cleaning. On 5.7L V8 models, catalytic damage is possible if gasoline was severely diluted with diesel or vice versa — follow TIS diagnostics.
Access procedure
- Relieve fuel pressure per TIS; disconnect negative battery
- Document fuel level in main and sub-tank if equipped
- Support vehicle safely; disconnect filler, vent, and EVAP lines as required
- Support and lower fuel tank assembly per Land Cruiser service manual
- Drain all tank sections into approved Class 3 containers
- Inspect tank, straps, and transfer valve; clean if contamination was run through engine
- Replace fuel filter and inspect lines; reinstall tank with new hardware per TIS
- Prime system, leak-check, and verify transfer valve operation before return to customer
Notes
- US 200 Series Land Cruiser ended after 2021; later 300 Series is not sold new in the US
- Some grey-market diesel Land Cruisers exist as private imports — treat separately from US-spec gasoline models

Frequently asked questions
Does the US Land Cruiser have two fuel tanks?
Many 200 Series US models have a main and sub-tank. Both must be drained and the transfer system checked during misfuel recovery.
What if I put diesel in my Land Cruiser at a truck pump?
Do not start the engine. US Land Cruisers require gasoline. Drain per TIS tank removal procedure and replace fuel filters before refilling with the correct grade.
Is there a fuel pump access panel on the Land Cruiser?
Most US Land Cruiser generations require tank lowering for complete access; confirm in TIS for your VIN rather than assuming under-seat access.
Will Toyota warranty cover misfuel damage?
No. Incorrect fuel is excluded as misuse under Toyota warranty terms.
