We are supposed to change the oil in our cars every 5,000 miles and, if we don’t, our car may begin to act a little wonky. This always got me thinking: Does this same rule apply for oil in our dirtbikes? Yes and no. Depending on the type of oil, the lifespan will vary. All oils have an expiration date and, once you pass these dates, the performance of the oil is not guaranteed, possibly leading it to thicken and prevent it from moving freely throughout your engine. Also, the amount of riding you do, along with the length of ride, all play a factor in whether or not you need to change your oil more frequently.

Another characteristic of oil is how it changes colours you may notice the color of your oil change from a clear liquid to a more tinted dark brown colour. This change does not necessarily mean it is time to replace the oil but, in reality, means the oil is doing its job collecting contaminants which colour the oil. There are a couple types of oil used in your dirtbike including brake fluid, coolant and engine oil. We put together a beginner’s guide to help you understand when it might be time to give your bike a tune-up in the oil department.

Brake Fluid

If you are a professional, changing your brake fluid should happen after every race. Since most of us are not professional it is recommended we change our brake fluid every 20 to 40 hours of riding. You will notice the colour of your brake fluid change, once it reaches that dark brown colour it is time to change. This is important because your fluid will collect contaminants from the engine and water. The danger of having too much water in your fluid is at a certain temperature the fluid will begin to boil. Also, always make sure extra brake fluid is being stored in a sealed bottle in a cool dry place. This will increase the lifespan and quality of the oil and keep your bike running well once you use the brake fluid. A general rule of thumb is to only keep brake fluid for up to 5 years before it is time to buy a new bottle.


 Like brake fluid, the engine coolant should also be well maintained and have regular maintenance if you want to get the most miles out of your bike. Although it is not recommended to change it every 20 to 40 hours, it is suggested to change your coolant 1 to 2 times per year. A bottle of engine coolant can be stored for up to 3 to 5 years. Unless the coolant has been mixed with distilled water. If this is the case, the coolant will not last as long because the water will degrade the coolants protective properties and could lead to your bike to overheating easier during a hard ride.

Engine Oil

Depending on the type of your riding you are performing whether it be motocross, single track or trails, it can vary how often you change the engine oil due to the amount if exposure your bike has to the elements. It is recommended the engine oil be changed out the most frequently and in some cases, be swapped after every ride. It is most commonly suggested to change your oil after every 5 to 10 hours of riding to keep your engine performing at a top level and also prevent it from receiving any damage from the elements and overheating. In storage and in a sealed bottle which has not allowed water, dirt, or any other contaminants to enter, a bottle of engine oil will be good for up to 5 years. After that then, well, it is time to buy new oil.

One thing to remember when it comes to oil and your bike, if you have any questions about the cleanliness, storage or contamination of your oil then throw it out! It is much cheaper to buy new oil, then it is to replace your engine. We hope this guide helps you keep your bike running at high performance for a long time coming!
