At the gas station, you have a choice of three grades of gasoline, each with its own octane number rating. While you may think regular, plus, and premium grades are suitable for any motorcycle, it’s important to know the significant impact octane has on performance. This guide will give you insight into the type of gas you should put in your ride so it can perform at its best.
Why Octane Matters
Using the correct octane rating for your motorcycle is essential for preventing engine knock, also called detonation or pre-ignition. Engine knock occurs when the air-fuel mixture ignites prematurely in the combustion chamber, leading to inefficient combustion and potential engine damage. The higher the octane rating, the more resistant the fuel is to knock. This makes higher octane fuels suitable for engines with higher compression ratios or turbocharging.
Deciphering Octane Number Ratings
Understanding octane ratings can be confusing, so here’s a quick breakdown.
- 87 Octane Gasoline – Regular gasoline is the standard fuel available at most gas stations and is suitable for most motorcycles.
- 89 Octane Gasoline – Plus gasoline, also known as mid-grade gasoline, offers slightly better performance and may be recommended for certain bikes.
- 91 or 93 Octane Gasoline – Premium gasoline has higher octane ratings and is typically recommended for high-performance motorcycles or those with advanced engine technologies.
Following Manufacturer Recommendations
It may be tempting to opt for a higher octane fuel for your motorcycle, but it’s essential to follow the manufacturer’s recommendations listed in the owner’s manual. Using fuel with a higher octane rating than required won’t provide any additional benefits and may result in unnecessary expenses. Conversely, using lower octane fuel than recommended can lead to performance issues and engine damage.
In other words, choosing the right fuel for your motorcycle is essential for optimal performance and engine health.
