What Octane Gas Does Ford Mustang Use?
3 Answers
Ford Mustang's official recommendation is to use 93 octane gasoline. The type of fuel to be used should be based on the manufacturer's guidelines. If the recommended type is 93 octane, then 93 octane should be used, but in emergency situations, 97 octane can be used. The following is an introduction to gasoline octane ratings: The octane rating of gasoline represents its octane number. For example, 95 octane gasoline consists of approximately 95% isooctane and about 5% n-heptane. Since isooctane has better anti-knock properties and n-heptane has poorer anti-knock properties, a higher octane rating indicates better anti-knock performance of the gasoline.
Having driven a Ford Mustang for years, I always fill it up with 95 or 98 octane gasoline because the engine's high compression ratio requires high-octane fuel to prevent knocking issues. The older V8 version is even more recommended to use 91 octane or above, while the newer EcoBoost models can go slightly lower, but the manual specifies it clearly. Remember to check the inside of the fuel cap or the manual for confirmation—don’t just follow random recommendations at the gas station. Using lower-octane fuel, like 92, may cause increased engine knocking, reduced power output, and even long-term damage to components. During maintenance, always pay attention to fuel quality to ensure the car runs smoothly and safely.
When I first drove the Mustang GT, the manual emphasized using gasoline with an octane rating of 95 or above, so I always fill up with 98. It makes the acceleration response quicker, the engine smoother, and provides much more stability at high speeds. Once during a trip, I used 92 octane, and the engine immediately developed abnormal noises, which scared me into changing the oil to fix the issue. Although higher octane fuel is a bit more expensive, it's more cost-effective in avoiding repair costs and can extend the engine's lifespan. Just make sure to check the octane rating when refueling, and it'll become a habit.
