What happens if I put higher octane fuel in my motorcycle?
Typically, you can, as long as the octane number is not too high; however, if the octane number is too high, the engine will usually overheat and its performance will suffer, especially because high octane gasoline has a knock resistance feature that prevents it from igniting easily before the timing is correct.
Can I run 100 octane in my motorcycle?
Fuel grade needs to match an engine’s state of tune. If your bike calls for regular, then there’s no need to fill up with higher octane fuel unless you’ve modified your engine in a way that makes detonation more likely, such as installing a high-compression piston.
What petrol should I use in my Harley?
The recommended fuel (according to my manual at least) is a min. of 91 octane. It’s required for the higher compression engines we have in the v-twin (9.5:1), any lower will cause pre-ignition and high compression chamber temperatures (and engine damage).
What octane is best for Harley-Davidson?
Every engine manufacturer specifies a minimum octane rating requirement for fuel. The majority of motorcycle engines, including all current Harley-Davidson engines, require 91 octane or higher (Premium) fuel, thanks to high compression ratios.
Is it OK to use 93 octane instead of 91?
Engine computers can usually adjust their timing to account for the increased octane levels, so if you put premium gas in a regular car, you probably won’t notice anything. However, some engines are not designed to burn higher-octane fuel, and you may see a reduction in performance and fuel economy.
Can I put 98 octane in my motorcycle?
91 = Basic, cheap, will run ok in some bikes though not recommended. 95 = Recommended by most manufacturers, clean, reasonable quality. 98 = premium quality if want to pamper bike, though not necessary. Some 98 fuels are denser than lower octane fuels which might effect mixture.
Is high-octane fuel better for a bike?
The 90+ octane gasoline is fuel meant for motorbikes that have excellent performance. It is what they refer to as premium fuel. These bikes have a higher compression ratio, and so they need Octane rated 90+ for them to function well. Of all the fuel types, the ones with 90+ Octane are the best.
Can I damage my engine with higher octane?
If you keep using lower-octane fuel for a prolonged period, you will have a damaged engine and emission control system. But if you use a higher-octane gas than your car needs, it won’t do any harm, nor will it benefit your car.
Does 93 octane give more power?
Raising the octane rating (also known as the anti-knock index) doesn’t change the energy content of a gallon of gasoline. A higher octane rating indicates greater resistance to knock, the early combustion of the fuel-air mixture that causes cylinder pressure to spike.
What happens if I use 98 octane instead of 95?
The higher the octane rating, the more compression it can withstand. Filling a car with 98 octane fuel, when it is recommended to use 95 octane fuel will only cause a problem to your pocket, as 98 is more expensive. You will travel the same kilometres as if you had refuelled with 95.
Is higher octane OK?
For most vehicles, higher octane fuel may improve performance and gas mileage and reduce carbon dioxide (CO2) emissions by a few percent during severe duty operation, such as towing a trailer or carrying heavy loads, especially in hot weather. However, under normal driving conditions, you may get little to no benefit.
Does premium gas make a difference in motorcycle?
Unless your motorcycle manufacturer says its engine requires premium (a few do), your bike was built to run properly on regular. Unless you have a high-compression engine and can adjust ignition timing to take advantage of the anti-knock properties of premium, your bike will run exactly the same as running on regular.
What happens if you put premium gas in an unleaded motorcycle?
It’s safe to use a mixture of premium and unleaded gas unless your motorcycle is only meant to use high-octane gas. But if you pour this mixture into a bike that uses premium quality gas, it will result in reduced engine performance and could damage the engine’s internal parts.
Can I put unleaded in my Harley?
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.

What is the best high-octane gas?
Highest octane. on the market. If you demand peak performance from your vehicle, then nothing less than Sunoco 94 Octane will do. Treat your car to 94.
Is 93 octane better than 95?
Under normal, moderate driving conditions there is no difference in your car’s performance between 93 and 95. Under severe driving conditions (full throttle, flat-out driving) high performance vehicles will experience a slight performance benefit when using 95.
Should I use 91 or 95 octane?
So, if your car requires 91 octane then you can use that, or if you’re happy to pay a little more for enhanced performance, you can use 95 petrol. The advantage of higher octane fuel is a greater stability under pressure – it is less likely to combust in the chamber before it’s supposed to do so.
Is 98 octane better than 91?
A way of remembering this is like the Olympics – 91 is bronze, 95 is silver and 98 is gold. Generally, the higher the number the better the fuel. But because manufacturers optimise their engine tuning for a specific RON, it’s important to fill your car with the right one. “Most cars can run on 91,” says Gisella.
Which petrol is best for a motorcycle?
Turns out regular fuel is recommended for the bike.
Can I put an octane booster in my motorcycle?
It’s safe for turbos, oxygen sensors and catalytic converters. Stops knocks, and raises MPG in high compression engines. One 15 oz. bottle treats up to 25 gallons of fuel.
Does 98 octane clean the engine?
There is Regular Unleaded (91RON), E10 Unleaded which increases the octane rating to 94RON, as it is mixed with between 9-10% ethanol, 95RON octane rating Unleaded and lastly 98RON octane rating Unleaded, which usually includes additives that can ‘clean’ internal parts of the engine to improve fuel consumption and long …
What happens if I put higher octane fuel in my bike?
Higher octane isn’t better than lower octane, it’s simply designed for engines with different compression ratios. Using the “wrong” gas for your engine here and there won’t make a significant difference initially, but over time it can cause premature wear or lead to engine knock.
Does higher octane fuel burn better?
Fuel with an 87 octane rating burns more quickly while higher-octane fuels burn more slowly. In engines designed for standard unleaded fuel, efficiency and performance is optimized for 87 octane and could actually perform worse with higher-octane fuel since the burn rate is slower.
Is XP95 petrol good for a bike?
However, in my experience I have seen that XP95 gives 10-20% better mileage even when I am using it in an Activa. For my dominar 400, the performance and fuel efficiency improves even more. Hence, xp95(the pink color coded) petrol is definitely worth the money.
Does running 93 octane make a difference?
In most cases, the difference in performance is small and something you may not notice during normal driving. If the car is designed for regular gas — or doesn’t specifically say that the car requires premium gas — go with regular. There are no benefits to putting premium gas in a car that doesn’t need it.
Does 93 octane add horsepower?
Raising the octane rating (also known as the anti-knock index) doesn’t change the energy content of a gallon of gasoline. A higher octane rating indicates greater resistance to knock, the early combustion of the fuel-air mixture that causes cylinder pressure to spike.
Does 93 octane burn better?
All grades of pump gas burn at the same rate. High octane resists detonation. Detonation is a second spontaneous source of ignition caused by temperature and/or pressure.
Can I put 98 octane in my motorcycle?

What octane fuel should a Harley Davidson engine use?
Can a low octane engine damage a Harley?
Can you use 87 octane fuel in a Harley Davidson?
Does 87 octane gas hurt a Harley?
You’ve got your Harley Davidson, you’re ready to hit the open road, and you’re wondering about fuel. Maybe you’ve heard that high octane fuel is the way to go for your hog. Maybe you’ve even seen “premium unleaded” at the pump and thought, “Hey, that’s probably better for my bike.”
But before you start filling up with the highest octane you can find, let’s take a minute to understand what’s going on under the hood.
Understanding Octane
Think of octane like a measure of how much pressure gasoline can handle before it explodes. We’re talking about pre-ignition here, not a full-blown explosion, but a sudden, uncontrolled burning that can damage your engine.
The higher the octane number, the more resistant the fuel is to pre-ignition. Regular unleaded (often 87 octane) is more prone to knocking, a rattling sound caused by pre-ignition. Premium unleaded (usually 91 octane or higher) is more resistant to knocking and is designed for high-performance engines that run at higher temperatures and pressures.
So, Does My Harley Need High Octane Fuel?
The answer is: it depends.
First, check your owner’s manual. Harley Davidson recommends using 87 octane fuel for most of its motorcycles. This includes classics like the Sportster and Dyna models.
But there are exceptions!
Here’s where things get interesting:
Harley Davidson touring models, like the Road King and Ultra Limited, often require 91 octane fuel.
Harley’s high-performance models, like the V-Rod and CVO, are explicitly designed to use premium fuel and will benefit from it.
Aftermarket modifications: If you’ve customized your Harley with performance upgrades, you might need to use higher octane fuel to prevent knocking.
Why Does Octane Matter?
It’s about engine health and performance. Using the wrong octane can lead to:
Knocking or pinging: This can damage engine components over time.
Reduced power: Your Harley won’t run at its best.
Fuel efficiency issues: Your bike might guzzle gas.
It’s Not Just About the Numbers
While the octane number is important, the quality of the fuel itself matters too.
Here are some things to consider:
Fuel additives: Some gas stations add extra additives to their fuel, which can impact performance and engine life.
Fuel storage: Old fuel can lose its quality and cause problems.
Seasonal changes: In extreme climates, you might need to adjust your fuel choice.
The Bottom Line: Know Your Bike
Consult your owner’s manual. It’s the ultimate guide to what your specific Harley needs.
Pay attention to the sticker on your gas tank. Harley Davidson often includes a reminder of the recommended octane rating.
Ask a knowledgeable mechanic or Harley Davidson dealer. They can help you determine the best fuel for your bike.
