What Happens If You Put Wrong Gas In A Dirt Bike?

what happens if you put wrong gas in a dirt bike

Getting the best outcome from your dirt bike, you need to put the right gas into it. But have you ever thought, what happens if you put the wrong gas in a dirt bike?

A rider will never get the best outcome by putting the wrong gas or mixing an inaccurate ratio in his/her dirt bike. This type of fault badly affects the dirt bike engines’ performance by creating issues like pinging or knocking during riding. It is crucial to put the suitable gas with the appropriate ratio in a dirt bike for more prolonged use.

In this article, I’ll briefly discuss the various aspects of dirt bike gas. I’ll also give you detailed information about the best 5 gas for dirt bikes in the last part of this article. So, don’t escape without finishing this article.

What Kind Of Gas Do Dirt Bikes Use?

Premium gas is the best option for dirt bikes. But most riders don’t like to use premium gas for his/her dirt bikes. Instead, they go for quality racing fuels. Here I’ll introduce you to two raw materials that use for making the best gas of dirt bikes:

1. High Octane:

High Octane is often used to make good quality dirt bikes fuel. The interesting thing is that you need to pay more for the higher number indicating octane. Generally, over 90-octane gas works well for dirt bikes. For better performance from your dirt bike engine, I suggest you use between 91 to 94 octanes.

2. Non-Ethanol:

Ethanol is vastly used to make vehicle fuels. But I recommend no one to use ethanol-based fuels for their dirt bikes because they attract moisture into your tank and cause erosion.

So, use such fuels for your dirt bikes that are made from non-ethanol. Non-ethanol-based fuels are OK for using occasionally, but don’t use them regularly because of erosion issues.

Differences Between Premium And Regular Gas Of Dirt Bikes:

You can use both premium and regular gas for your dirt bikes. But there are a few differences between them. Below I write down these differences:

DifferencesPremium Gas Of Dirt BikesRegular Gas Of Dirt Bikes
Octane RatingPremium gas of dirt bikes has a higher octane rating.Regular gas dirt bikes have a higher octane rating.
Price RangeThe price range is higher than the regular gas of dirt bikes.The price range is lower than the premium gas of dirt bikes.
Working EfficiencyDirt bike engines work more efficiently with this type of gas.This type of gas creates some issues for dirt bike engines and works less efficiently.
CapabilityMore capable of resisting pinging or knocking issues.Less capable of resisting pinging or knocking issues.

Putting premium gas in a normal dirt bike engine doesn’t give you the expected outcome. Consequently, check your owner’s manual to know premium or regular gas is recommended by the manufacturer for your dirt bike.

What Happens If You Put Regular Gas In A 2 Stroke Dirt Bike?

You should definitely mix regular gas with 2-stroke oil before putting it into the engine; otherwise, you’ll face knocking or pinging issues during riding. Basically, 2-stroke dirt bike engines depend on lubrication for running at full speed. But without lubrication, they’ll begin to heat and stop properly working very soon. 

As a result, your dirt bike suddenly stops on the roads. To avoid such a situation, mix regular gas with the oil rightly and then put it in a 2-stroke dirt bike.

What Kind Of Gas Does A 4-Stroke Take?

4-stroke dirt bikes usually take non-ethanol-based gas fuels. Even 4-stroke dirt bike engines are capable of getting along even under 90 octanes. But to get smooth dirt bike riding, I’ll suggest you to use octane boosters or race fuels with above 90 rating octanes. The cost will be a little bit pricey for that.

5 Best Gas For Dirt Bikes:

After deep research, I selected these 5 best gas for dirt bikes. Here I list them with pertinent information. Let’s check them:

1. Race Gas Fuel Concentrate:

Sometimes it’s too difficult to manage high-octane gas for your dirt bikes. In such a situation, most dirt bike riders go for a low-octane. Well, you can get along with low-octane, but it creates high noise and discomfort for the engines. 

Hence, instead of a low-octane fuel, it’s better to use a concentrate or an octane booster. You’ll get different brands of concentrate in the market, but among them, I recommend you to try ‘Race Gas Fuel Concentrate.’ Now, you may ask why I recommend it to you.

First of all, I personally use this product. ‘Race Gas Fuel Concentrate’ is not only suitable for your dirt bike but also it is equally good and suitable to use for motorcycles, cars, and other off-road vehicles. You can comfortably try it with every type of 2-stroke oil. 

To get a smooth burn, just mix ‘Race Gas Fuel Concentrate’ with your regular fuel and then give it a boost by higher the octane. Though this product’s price is a little bit higher than regular fuel, I suggest that you should use it only with your regular fuel for saving money.

  • The best option when you don’t get quality gas in the neighborhood for your dirt bike. 
  • Useable with 2-stroke oils.
  • It is specially made for dirt bikes and other off-road vehicles.
