What grade of gasoline does the Mazda RX8 use?

[DeElaina]

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.

My friend and I have both driven the Mazda RX-8, and we strongly recommend using 95-octane gasoline. This car is equipped with a rotary engine that requires higher octane levels, and 95-octane fuel helps prevent internal detonation risks, allowing it to perform more powerfully. Initially, I didn’t know better and used 90-octane, which caused the engine light to come on and nearly led to issues. Now, I always head straight for the 95-octane pump and even add fuel additives for maintenance. Remember, don’t skimp on fuel—lower octane can easily cause carbon buildup and make acceleration sluggish. For daily drives or weekend getaways, the power response is incredibly satisfying.

My Mazda RX-8 runs best on 95 octane gasoline. The rotary engine characteristics require high-octane fuel, and 95 octane effectively reduces the likelihood of knocking. I've done comparisons, and 95 octane is much smoother than 92 octane, with no acceleration hesitation. It's better for the engine in the long run.
