Difference Between 2-stroke oil and 4-stroke oil

As they say if you are going to do it, then you better do it right! So for you to ensure that your dirt bike engine is lubricated by the best oil possible, we have to first get you through the basics. Generally there are two types of combustible engines; 4-stroke and 2-stroke engine.

A stroke occurs during the combustion cycle when the piston moves to and from the valves. A combustion cycle is when gas and air are ignited then expelled out. For 4-stroke engines the power is produced with every 4 strokes of the piston.

While power is produced every 2 strokes of the piston for a 2-stroke engine. The other major difference is that with a 4-stroke engine there is no mixing of fuel and oil as the oil is injected from a separate compartment, while in a 2-stroke engine the oil must be pre-mixed with the fuel.

Factors to Consider When Buying a Dirt Bike Oil

By now I am sure you understand the level of sensitivity and keenness required to make this purchase is high, it’s not like grocery shopping where you’ll just go to the snacks aisle pushing your favorite snack flavors into the trolley without even twitching.

You have to ask yourself a number of questions. What will you be using the dirt bike for? How do you ride the dirt bike? Will you be riding in wet grounds? Will you be riding off-road? Only when you have clear answers will you be in a position to pick the right dirt bike oil.

The best place to start is your dirt bike manual. It can help you align your compass to the direction you can follow to hit the jackpot. Below is a detailed description of some features you can look for, think of them as some tricks up your sleeve!


Viscosity is the ability to resist flowing or rather the thickness of the lubricant. Lubricants with a high viscosity are thick and resist flowing, rendering them a bad choice since they increase friction and force the engine to use more power in order to move the parts.

But here is where it gets real tricky you are required to get a lubricant with a medium viscosity such that it is capable of preventing the moving parts from grinding on each other. A low viscous lubricant is a definite no no! It’s almost the same as saying water would have been suitable.


You also read the descriptions of the oil you are buying to know if its conventional oil or synthetic oil with added chemicals. If you rarely put your engine through rough conditions then the simple conventional oil will suffice.

But you are accustomed to riding your dirt bike often in conditions that require the full exertion of the engine’s power then synthetic oil is probably best due to a number of reasons. It provides better lubrication to keep your engine around for long and at a high performance for that matter. 

The addition of chemicals also makes synthetic oil well equipped to maintain its viscosity even at high temperatures which is a quality you need for better performance of your dirt bike. Since this thickness is able to prevent frequent and rapid wear at all costs!

Cleaning agents

To avoid any engine damage you have to go for oils that are cleaning agents as well. For starters they are able to clean the valves in your engines and leave it working exceptionally well. The top notch condition of your engine is bound to bring happiness at the footsteps of your door!

It is also able to suspend the carbon particles, preventing the formation of the formation of sludge on the internal parts of the engine, which eventually translates to the damage of your precious dirt bike engine.


Is it okay to separate the engine and transmission oil?

There really is no need to separate them, for one the majority of dirt bikes have a common oil pan making the engine and transmission oil the same. But these oils have additives that ensure both functions are adequately handled.

How often should I change my oil?

This depends on the model of your dirt bike and its requirements. So it is wise to fall back to the manufacturer’s manual and get a clear answer , since everyone has their own ‘routine’ when it comes to the frequency of changing the oil.

It is my hope that you found this article helpful. If you still haven’t found what you’re looking for, then I have a good recommendation for you.


On the face of it buying oil for a dirt bike sounds pretty easy , but once you get to the specifics your realize it’s only easy if you carefully check off all the necessary features required to get oil specifically designed for your dirt bike.

My only advice is that don’t overthink or overdo it just follow necessary instructions to navigate through the various brands and find the right one. The Maxima Catro 927 2 Stroke Dirt Bike Oil snatches first place on that list.
