Which fuel is used in Supra MK4?
The Supra MK4 runs on gasoline (petrol), specifically premium, high-octane unleaded fuel.
The Mk4’s 2JZ-GTE turbocharged inline-6 engine is designed to run on unleaded gasoline, with a strong emphasis on high octane to prevent knocking under boost. Octane requirements vary by market, and owners should follow local guidelines and the vehicle’s manual to choose the correct fuel grade.
Engine and fuel basics
The Toyota Supra Mk4 (A80) is powered by the 2JZ-GTE twin-turbo inline-6 engine, which relies on gasoline (petrol). For optimal performance and to protect the engine under boost, high-octane premium fuel is recommended. Exact octane guidance can differ by country and fuel labeling standards.
Global octane guidelines and regional notes:
- United States and Canada: Premium unleaded gasoline with an octane rating of 93 AKI or higher is typically recommended.
- Europe and the United Kingdom: High-octane premium petrol is advised, commonly around 97–98 RON; use the highest grade available that meets OEM guidelines.
- Other markets: Use premium unleaded gasoline with octane ratings at or above local standards comparable to 95+ RON; always check the owner's manual for exact specifications.
Note about ethanol blends and fuel options
- In many regions, premium fuels are offered as ethanol blends (E10 or similar). The 2JZ-GTE is designed for unleaded gasoline, and ethanol blends can affect performance unless the engine is tuned accordingly. If you plan to use ethanol-containing fuels, consult a qualified mechanic or tuner and consider ensuring compatibility with your ECU and fuel system.
Conclusion: To maintain reliability and performance, use the recommended high-octane premium gasoline and avoid low-octane fuels. If you are in a region with limited options, opt for the highest octane available and follow the manual for guidance.
Additional considerations
Practical notes for owners
Always verify fuel requirements with your specific vehicle’s manual and be mindful of regional octane labeling (AKI vs. RON). In markets where premium fuels are scarce, seek the highest-octane option available and consider professional advice if you plan to run higher boost or modification work.
Summary
The Supra Mk4 is powered by gasoline (petrol) and requires premium, high-octane fuel to support its turbocharged engine. Octane recommendations vary by region (roughly 93 AKI in North America and 97–98 RON in Europe), with a general emphasis on premium unleaded gasoline. Check your manual and local fuel options, and avoid low-octane fuels to protect engine performance and longevity. Ethanol blends should be approached with caution unless the engine is tuned for them.
