#2. Mobil 1 4 Cycle Motorbike Oil
Mobil 1 is another household name that everyone knows in the Moto community. They make the best dirt bike oil for those who have a 4-stroke engine.
This is an advanced full synthetic oil. Overall, we feel very comfortable sticking with this brand over high-performance and high-priced boutique brands. We just don’t think that higher-priced oil gives you a significant performance boost.
The Mobil 1 4-stroke oil gives you pretty decent and smooth clutch engagement as well as staying around for longer than your average dirt bike oil on the market. It also offers pretty good protection for your engine and transmission and gives you noticeably smoother shifting and engine braking. What more do you need?

#3. Royal Purple HP 2-Cycle Dirt Bike Oil
Next on our list of the best dirt bike oil is the Royal Purple HP 2 Cycle Oil. This stuff is a multi-use motor oil that is good for dirt bikes as well as anything with a 2 stroke engine. The standout feature is definitely the wear protection. We say in general that it offers better wear protection as well as corrosion and rust protection than most of the brands out there.
We also really like the fact that it is ashless, which helps minimize exhaust deposits. It also keeps sparking plugs and exhaust ports clean because of its synthetic solvency. All in all, we say that the oil film strength is quite strong and will significantly optimize engine efficiency at a very low cost.

#4. Spectro Performance Oils 2 Cycle Oil
Another great boutique brand in the world of performance dirt bike oils is the Spectro brand. We like to run this stuff because it significantly reduces excessive solvents in 2-stroke engines. We recommend that you run this stuff at leaner ratios if you want higher levels of detonation protection as well as stopping plug fouling and smoking.
In general, we find that it provides a nice oil film and gives all of your parts adequate protection even in extremely higher temperatures where other brands will break down. Although the price point is a little steep, this is one of the better pre-mix two-stroke oils you can buy if you are after durability and protection.

#5. Maxima 10W-40 Motorcycle Engine Oil
Lastly, we have the Maxima 10W-40, which is a 4-cycle oil that is highly stable and gives your engine long life. This brand is a multi-grade motorcycle-specific oil. The thing that separates the Maxima from the rest is that you get viscosity stability for all air and water-cooled 4-stroke engines with integrated transmissions.
We don’t really know what they put in there but it works. The company reports using an “exclusive blend of petroleum base stocks and advanced anti-wear, anti-shear additives.” Additionally, we really like the fact that it can handle peak temperatures as well as extreme loads with its anti-scuff additives.

Conclusion on the Best Dirt Bike Oil
In conclusion, the best oil for a dirt bike depends on the make of the bike and the riding conditions. For example, if you ride in hot weather, you might want to use a different oil than if you ride in cold weather. There are many different brands and types of oils, so it’s important to do some research to find the best one for your bike.
However, if you are an experienced rider who goes hard on your bike, then Maxima Castor 927 2-Stroke Dirt Bike Oil is the best option for you. On the other hand, and if you are a beginner or ride more conservatively, then one of the other options, like Mobil 1 4 Cycle Motorbike Oil, would be better suited for you.
