Can I Use Diesel Oil in My Motorcycle?

Many people wonder: Can I use diesel oil in my motorcycle? Here are a few things to consider: Cost, Viscosity index, and recommendations. Then read on to discover which oils are the best choices for your motorcycle. Then make your decision! If you have never tried using diesel oil, this article will help you decide! And don’t forget to check the Viscosity index before you buy!

Alternatives to diesel oil

If you’re looking for an energy-saving alternative to diesel oil for motorcycles, you’ve come to the right place. If your motorcycle has a traditional oil pump, you might be wondering if you can use other oils in its place. Generally, the best choice for your motorcycle is 10w-50 or 15W-50. However, you should know that the viscosity of these oils is not the same as those for cars. So if you’re wondering if you should switch to the new oil, you can try to make sure that it’s compatible with your bike’s specific needs.


If you’re wondering what the average price of diesel oil for motorcycles is, you’re not alone. Compared to synthetic motorcycle oils, diesel oil is the most expensive option for your bike. But while Shell Rotella may be cheap, synthetic oils are superior in several ways. For starters, synthetic oils have anti-corrosion properties, which will protect your motorcycle engine against rust. Plus, they’re better for your motorcycle engine than diesel oil.

Viscosity index

The SAE grading system is the industry standard for classifying oils based on their viscosity index. Generally, motorcycle engine oils will be labeled as 10W-40 or 20W-50. The W is for winter and represents the viscosity of the oil at low temperatures. The number after the hyphen refers to the viscosity of the oil at high temperatures. Using the wrong oil could result in damage to engine parts and a loss of power.


It’s possible to use diesel oil in a motorcycle, but there are several considerations to keep in mind. Because diesel engine oils don’t have API ratings, they can sheer down and lose viscosity in common sumps. This is especially important in motorcycles with a clutch, which shares engine oil with the clutch. Motorcycles also share similar transmission characteristics with automobiles, so the lubricant must meet specific requirements.


Before you begin your lubrication project, you’ll need to make sure you understand the differences between gasoline and diesel engine oils. While both types of oils have different viscosities and specifications, diesel oils are generally safer to use in motorcycle applications than gasoline. Typically, you’ll find 15W-40 oil easier to locate than 30W oil. For best results, use a high quality heavy-duty universal oil with the correct viscosity rating.
