If you want to keep your bike running for a long time and want it to perform like it did when it was brand new you’ll have to maintain the bike regularly. One of the best things is changing the oil and in this post, I’ll show you how to change the oil in a 2 stroke dirt bike.

Changing the oil in your bike is a super simple process and should be done on a regular basis. It’ll all depend on what bike you have but on average it should be done every 5-10 hours or so. Obviously, the more you do it the better but as long as you’re around the timeframe you should be good.

If you don’t change your dirt bike oil on a regular basis there are a number of things that will go wrong. The first thing is that your engine will run too hot and will make a lot of the parts wear and break down. If you’re curious what will happen to your engine if you don’t have oil, check out the video at the bottom.

It’ll only take about 5-10 minutes to change your oil and it’s cheap to do so. All you’re going to need is the oil (obvious), a drain pan or bucket, and a wrench. Let’s jump into how to get started:

How Do You Change The Oil On A 2 Stroke Dirt Bike?

  1. The first thing I always do when I work on my bike is to give it a wash and make sure it’s clean. If you leave dirt and mud on your bike for a long period of time it can actually start to corrode the sprockets and chain. It’ll also prevent debris getting into your bike when you’re changing any of the fluids. It’s a good habit to get into so just do it.
  2. When you’re changing your engine oil you should make sure the bike is warm. The oil will be easier to drain when it’s warm so start it up and let it run for 3-5 minutes.
  3. On the side of the bike, you’ll want to unscrew the dipstick (that’s where the new oil will go).
  4. Place a drain pan or bucket under the bike and remove the drain bolt (it’ll be under the bike). Wait until the oil drips out and make sure you get rid of the oil properly and don’t dump it down the drain.
  5. Take some new oil and put it on the threads of the drain bolt. Put the drain bolt back on the bike.
  6. Take your new oil and put the correct amount in where the dipstick was (the first part you unscrewed). You can look in your manual for the correct amount and which type of oil to put in. You can also see the correct amount of oil to put in using the dipstick (if your bike has one).
  7. Take the dipstick and give it a good clean to make sure there’s no dirt or debris that’s on it. Put a little bit of oil on the threads and screw it back in place.

How Often Should You Change The Oil On A 2 Stroke Dirt Bike?

On average, you should change your 2 stroke oil every 5-10 hours. It all depends on how hard you ride it but the more you do it the better off you’ll be. If you go longer it’ll slowly wear down the transmission.

If you’re just casually riding through the trails you could easily get away with changing the oil every 10 hours or so. If you’re racing the bike you’ll want to change it more often (closer to 5 hours). I do know people who go longer than this between oil changes and haven’t really had any problems with their bike.

If you don’t already have one I’d recommend you get a magnetic oil drain plug. It has a magnetic tip that will actually attract and pull all of the metal floating around in your engine so you can easily remove it. They’re under $20 and you’d be surprised about how much metal they actually collect. It’s better for your bike and it’ll keep things running smoothly for years to come.

What Kind Of Oil Do You Put In A 2 Stroke Dirt Bike?

It’s recommended that you use a high performance 2 stroke oil. Do not use regular 4 stroke oil and don’t cheap out either. You’ll be way better off in the long run if you spend the little bit extra each time you change the oil on your dirt bike.

There are three different types of oil:

  • Conventional oil.
  • Synthetic oil.
  • Castor oil.

It seems like the consensus winner is the Castor oil and that’s why I’d recommend it. I don’t ride 2 strokes myself but know many people who do and most people use and suggest this oil from Amazon. It’s got 4.5 stars and that’s good enough for me.
