Lexus GX 460 V8 Fuel System Service Malaysia
1UR-FE uses multipoint port injection — 8 injectors rarely need cleaning, but a fuel system service every 80,000 km maintains optimal combustion. Fuel pump: 150,000–200,000 km lifespan. Use RON 95 minimum; RON 97 recommended. The V8's 80-litre tank means fuel economy matters — real-world Malaysia: 14–18L/100km in city traffic.
Lexus GX 460 Fuel System
- GX 460 (1GR-FE): sequential multiport injection (SFI) — no direct injection; intake valves stay clean; fuel system straightforward
- Fuel pump: in-tank electric pump; GX 460 fuel pump is reliable but replace if hard starts or fuel pressure below spec
- Fuel tank: GX 460 has large capacity tank — worth checking for any signs of tank corrosion or vapour lock issue on older units
- Fuel quality: RON 95 sufficient for 1GR-FE; 4WD off-road use on long trips — full tank advised before remote driving
