What grade of cars is generally suitable for 98 octane gasoline?
2 Answers
98 octane gasoline is suitable for what type of cars mainly depends on the compression ratio of the car engine. Due to its high octane rating and high price, 98 octane gasoline is mostly used by luxury cars and is known as "noble gasoline". It is also defined as suitable for gasoline cars with an engine compression ratio above 11.6. 98 octane gasoline is gasoline whose octane number is equal to a mixture of 98% isooctane and 2% n-heptane. The following is a related introduction to 98 octane gasoline: 1. Advantages: The advantages of 98 octane gasoline are "two highs and two lows", that is, higher anti-knock performance and power performance, and lower harmful substances in gasoline and lower exhaust pollution. 2. Applicable vehicles: Due to its high octane rating and high price, 98 octane gasoline is mostly used by luxury cars and is known as "noble gasoline". It is also defined as suitable for gasoline cars with an engine compression ratio above 11.6. Note: The use of gasoline is not the higher the octane rating the better, and the gasoline octane rating recommended in the manufacturer's vehicle manual should be used.
As an experienced driver who frequently drives, I've driven high-end cars like Mercedes-Benz and BMW. 98-octane gasoline is particularly suitable for them because their engines have high compression ratios, and the high octane rating helps prevent knocking, making the car run smoother. For ordinary cars like Honda or Toyota, whose engines are less advanced, using 98-octane fuel is just a waste of money and may even cause carbon buildup. I usually refer to the owner's manual to confirm if it's necessary before using it. Don't blindly chase higher octane ratings—if you use it in a car that isn't suited for it, it may increase maintenance costs and even affect emissions.
