Best Gas For 4 Stroke Dirt Bike (2024 Update)
Choosing the right fuel is crucial for getting the most out of your 4 stroke dirt bike. Using the incorrect gasoline can lead to poor performance, engine damage, and expensive repairs down the road. When shopping for gas, there are a few key factors savvy dirt bike riders consider before filling up.
First, you’ll want to choose a fuel with the proper octane rating for your bike’s engine. Most modern 4 stroke motors require gas with an octane rating of at least 87. Using a lower octane gas risks detonation within the combustion chamber, which can reduce power and cause engine knocking. Higher performance bikes may call for premium 91 or 93 octane fuels for maximum output.
You’ll also want to be mindful of ethanol content, as the alcohol additive can attract moisture and corrode metal and rubber components over time. Many riders opt for pure gasoline when available or limit ethanol content to 10% or less. Sticking with name brand fuels from reputable stations further reduces the likelihood of contamination issues.
Does premium actually mean premium performance for your 4 stroke dirt bike? How much ethanol is too much for your bike’s fuel system? Asking key questions like these will lead you towards the optimal gas for your machine. With the right fuel powering your engine, you can push the throttle with confidence knowing your bike is running in prime condition.

In a high-performance dirt bike, knocking can lead to engine damage and decreased performance.
Using a fuel with a higher octane rating than recommended for the bike can actually decrease performance, as the fuel may not burn efficiently in the engine. On the other hand, using a fuel with a lower octane rating than recommended can cause knocking and damage to the engine.
It's important to consult the owner's manual or speak with a mechanic to determine the recommended octane rating for a specific dirt bike model. Using the recommended fuel can help ensure optimal performance and prevent engine damage.
How often should you change the gas in a 4 stroke dirt bike?
The frequency of gas changes in a 4-stroke dirt bike depends on several factors. First, it is essential to note that gasoline has a shelf life of about 3-6 months. Therefore, if you do not use your dirt bike frequently, you may need to change the gas every few months to ensure that it does not go bad and damage your engine.
Secondly, the type of gasoline you use can also affect how often you need to change it. If you use ethanol-blended fuel, it can absorb moisture from the air, which can lead to phase separation and cause damage to your engine. In this case, it is recommended that you change the gas every 30-60 days.
Lastly, if you use your dirt bike frequently, you may need to change the gas more often, especially if you ride in dusty or dirty conditions. This is because dirt and debris can get into your fuel tank and contaminate your gas, leading to engine problems.
In conclusion, it is best to check your owner's manual for specific recommendations on gas changes. However, as a general rule, it is recommended to change the gas every few months, depending on your usage and the type of fuel you use.
