What grade of gasoline does the Mazda RX8 use?
2 Answers
Mazda RX8 uses 95-octane gasoline. The characteristics of gasoline are: 1. Volatility; 2. Stability; 3. Anti-knock properties; 4. Corrosiveness; 5. Cleanliness. Gasoline is a volatile, flammable hydrocarbon mixture liquid obtained from petroleum through fractionation, cracking, or pyrolysis, and can be used as fuel. The Mazda RX8 is a sports car with body dimensions of: length 4460mm, width 1770mm, height 1340mm, a wheelbase of 2700mm, and a fuel tank capacity of 65 liters. It is equipped with a 1.3L naturally aspirated engine, producing a maximum horsepower of 231PS and a maximum power of 170kW, with a maximum power speed of 8200 rpm. It is paired with a 6-speed manual transmission.
I drive a Mazda RX-8, and using 95-octane gasoline is the safest choice. The rotary engine is different from other models—its complex internal structure makes it prone to knocking. 95-octane fuel has a higher octane rating, ensuring smoother operation and preventing sudden stalling or engine damage. I once tried 92-octane, and the car shuddered slightly at startup, with slower acceleration. After switching to 95, the power delivery felt more stable. While 98-octane would be even better, 95 is sufficient for daily driving. Always check the manual—the manufacturer recommends 95-octane or higher. Long-term use of lower-grade fuel can shorten engine life, and don’t delay oil change intervals. Also, rotary engines naturally consume more fuel, so using high-quality gasoline can save on repair costs.
