Quick Answer: Do Motorcycles Really Need Premium

Gasoline contains octane, which is a chemical that prevents the premature combustion of engine fuel. Harley-Davidson advises owners to use only premium fuel for their motorcycles. Like the Big Twins used in Harleys, large V-Twin engines have higher compression ratios than other engines do.

Should you use premium in motorcycle?

If you’re running premium in a bike that calls for regular because you think it will make more power or net you more mpg, you’re wasting your money. The only reason you need to upgrade your gas is if you’ve installed high compression pistons or advanced your ignition timing, or done some other mod.

Can you use regular gas in a motorcycle?

You can put any gas in your motorcycle as long as your motorcycle will accept it. Depending on the make and model of your motorcycle, premium fuel may be the only choice. If you have a bike that accepts regular fuel, it will say so in the operating manual.

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.

Can a Harley run on regular gas?

Many Harley-Davidson owners have asked if they can use 87 octane gas in their motorcycles. Harley-Davidson advises owners of all fuel-injected models to use premium unleaded gasoline. Generally speaking, if your motorcycle is equipped with a high compression engine, you should run high octane gasoline.

Is premium gas bad for motorcycle?

It just burns slower. If the manufacturer doesn’t recommend high octane gas for your bike, then you’re just wasting money by using it. The exception to this is if you notice pinging or knocking when using lower octane gas in those cases they recommend going with a higher octane gas.

Do motorcycles need 93 octane?

Fuel grade needs to match an engine’s state of tune. 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.

What gas is best for motorcycle?

Pure Unleaded Fuel: Most motorcycle manufacturers recommend owners to use pure gasoline in their motorcycles. Unleaded fuel provides the best performance and efficiency in all motorcycle ratings.

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.

Is it OK to mix premium and unleaded?

Can I mix premium and unleaded gas? Yes, drivers can mix the two types of fuel. The combined gas types will result in an octane level somewhere in the middle — something the vehicle “will survive,” according to The Drive.

Is high octane bad for motorcycle?

Engines must use the proper octane fuel to avoid knock and provide reliable operation.” So higher octane ratings are important for engine preservation and operation in bikes that have high compression ratios and, depending on boost pressures anticipated, turbocharging.

Should I use non ethanol gas in my motorcycle?

Pure Unleaded Gasoline Without Ethanol is Best for Motorcycles. Most motorcycle manufacturers urge owners to use pure gasoline in their motorcycles. At least one motorcycle maker, Ducati, considers ethanol to be a gas additive and its use voids the cycle’s warranty.

Does premium gas burn slower?

Does high grade gas burn slower? Higher octane gas is processed through additional steps that further refine the blend and cause it to burn more slowly than lower octanes. Because higher octane gas burns slower, it is more resistant to knock when subjected to higher RPM and cylinder pressures.

Can I use 100 octane in my motorcycle?

Race fuel (100 to 110 octane and higher) should be reserved to race motorcycles or motorcycles with high compression engines. The best power to performance ratio is usually achieved with the lowest octane fuel that does not produce pinging or preignition.

Can I put 110 octane in my motorcycle?

So, yes, 110 octane fuel can be used in motorcycles. Fuel with an octane rating of 110 can be considered racing fuel, and it is very hard to come by. Using 110 octane fuel, in general, will not provide any benefits in terms of speed or performance.

Why do Harleys have 2 gas caps?

So, you had two tanks, one for oil and one for gas. It evolved to two gas tanks when contained oil systems became the norm (maybe because two small gas tanks were easier to manufacture than one big one?). Now, it’s purely a styling and heritage exercise.

Can I use regular gas instead of premium?

Most cars on the road recommend a standard grade 87 or 89. Premium gas 90-93 is completely okay to put in a standard vehicle. Car experts say there is no risk of damage to a standard car using premium fuel.

Which is better unleaded or premium gasoline for motorcycle?

premium has higher octane, and regular has lower octane. But both are unleaded. Therefore they do not need high octane fuel. These type of vehicles are highly recommended to just use regular gas (which we wrongly call “unleaded”).

What happens if I put higher octane fuel in my motorcycle?

The important takeaway here is that octane itself does not cause the power, it merely allows an engine to make power if it’s built to do so. Using high-octane fuel in a standard-compression engine won’t give you one more lick of power. It takes more energy to ignite the fuel, resulting in power loss.

What octane is race fuel?

Sunoco® Standard™ is a 110 octane leaded race fuel that is used in many forms of motorsports.

Is premium gas better?

The main difference with premium is its octane rating — 91 or higher compared with 87 for regular octane. The higher octane gives premium gas greater resistance to early fuel ignition, which can result in potential damage, sometimes accompanied by audible engine knocking or pinging. Premium gas is not “stronger” gas.

Which is better for bike petrol or octane?

Generally there are no difference between Petrol and octane both are gasoline. And chemical building is also same (C8H18). Both helps the bike to run. Petrol, octane or gasoline has international rating called RON or (Research Octane Number).
