What octane gas should I use in my motorcycle?

The kind of gas motorcycles should use is ethanol-free higher octane gasoline (no less than a 91 rating). Motorcycles are considered to have high compression engines which is something that requires high octane.

Is high octane gas better for a motorcycle?

A higher octane gas will net more horsepower, get better mileage, or offer better thrall response. High octane gas alone does not yield more power unless it’s preventing detonation, which is also known as engine pinging or knock. The higher the octane, The more resistant the fuel is to detonation.

What is a good compression ratio for 91 octane?

The generally accepted conservative estimate is 8.0 to perhaps 8.5:1 dynamic compression ratio for 91 octane pump gas. This tends to be true for older, traditional engines with less effective combustion chambers. But for later model engines with better chambers, that could be improved to 9.0:1 dynamic.

Should I run 93 octane in my motorcycle?

Even then, unless your engine is knocking on 87 octane, it’s not going to make more power or run any better on 89 or 93. On the flip side, if you’re thinking of going cheap and putting regular in a bike designed to burn premium, you’re at risk of engine damage.

Does 93 octane make a difference?

Regular gas is rated at 87 octane in most states, while premium gas is often rated higher at 91 or 93. Essentially, the higher the octane rating, the lower the likelihood that detonation happens at the wrong time. On occasion, this occurrence will likely not harm your vehicle.

Can I run 89 octane in my motorcycle?

The engine’s compression causes low-octane fuel to spontaneously combust before the spark plug ignites the fuel. When I run 89 octane, I might have a problem. Motorcycle engines with high compression from the factory will typically require high-octane fuel.

Is 10.5 compression ratio high?

Member. When you’re dealing with a car engine, anything over 10.5 to 1 is usually referred to as high compression.

What octane is needed for 9.5 compression?

The standard recommendation for street engines running on pump gas has always been to shoot for a 9.0:1 to perhaps 9.5:1 compression ratio. This is in order for the engine to safely work with pump gas, which for much of the country, is limited to 91-octane.

How do I know what octane to use?

You’ll find the minimum octane rating in the owner’s manual, and cars that require premium fuel will usually say so on or near the gas cap, and sometimes even by the fuel gauge. If your car specifies premium fuel, use the good stuff.

What is the best octane for nitrous oxide?

C16 is our MON 117 Octane fuel for turbocharged engines, blown engines and nitrous applications with CRs up to 17:1. It’s recommended by the top nitrous oxide companies and is the Spec Fuel for NHRA Comp Eliminator”. For Circle track fuel, Freddie Turza described VP’s CHP fuel, “ CHP, which stands for ‘Crate HorsePower’, and is leaded.

What is the octane rating for gasoline?

Gasoline with an octane rating of 85 is available in some high-elevation areas of the U.S. (more about that below). The octane rating is prominently displayed in large black numbers on a yellow background on gasoline pumps.

Is it worth it to put high octane in a car?

If your vehicle requires a high octane rating, the manual will tell you. Otherwise, don’t pay the extra 15 to 20 cents per gallon for a higher octane fuel. “Putting high-octane fuel into a car that only needs low-octane fuel is a total waste of money,” says Arman.

How do you measure the octane requirement of an engine?

The octane requirement of an engine in a vehicle can be measured on a chassis dynamometer with a standard series of reference fuels. Racers are not expected to conduct these tests but must be able to recognize when they need a higher-octane number gasoline.
