6 Best Two-Stroke Oils for a Jet Ski (Yamaha, Sea-Doo & Kawasaki)

As part of your jet ski ownership, you’ll need to add some two-stroke oil quite often. But which one should you choose? That’s where I’ll come in.

Through my research, I figured out the most popular brands that many owners are using. I followed the conversation in a Facebook group recently and came up with these findings.

The most popular 2-stroke oil for a jet ski are:

1. Yamaha Yamalube Watercraft 2-Stroke Oil

The first on my list is Yamalube by Yamaha which is perfect for the Yamaha owners among us. You can buy this in bulk if you’re wanting to not just save a few dollars, but you won’t catch yourself out if one drum isn’t enough.

2. Sea-Doo PWC Synthetic Jet Ski Oil for Two Strokes

Of course, Sea-Doo has its own brand of jet ski oil. The best is their XPS series E-TEC and you’ll find it at 293600133 on Amazon. I notice it’s a little more expensive if you purchase this in smaller quantities.

3. Maxima Castor 927 2-Stroke Racing Premix Oil

If you don’t want to use the PWC oil from the 2 main manufacturers, then aim for Castor 927 which is popular as refined castor oil. It’s especially ideal for those of us who like to ride jet skis in salt water as its corrosion and rust protection properties are simply excellent. Not only this, but it’s biodegradable meaning it isn’t harmful for those of us who ride through sensitive environments.

4. Valvoline 2-Cycle Marine Motor Oil

Another great option to consider is Valvoline oil for outboard engines. This certainly isn’t my first choice as it’s really designed for outboards and other 2-stroke engines but if that’s all you have available, then you can get by for now with this.

5. Lucas Oil Semi-Synthetic 2-Cycle Oil

If you’re on the search for semi-synthetic oil for a personal watercraft, then Lucas makes a great choice. Before you buy this one, I’d be checking your particular make/model with your local dealership as it’s not compatible with all engines out there.

6. Quicksilver Premium 2-Stroke Engine Oil for PWCs

The last on my list of recommendations actually happens to be one of the best all-rounder brands around. This is perfect for Yamaha, Sea-Doo and Kawasaki jet skis to reduce corrosion and promote longevity. Perfect if you also have a boat, a dirt bike and other machines that need 2-stroke oil. It’s priced higher but the quality is reflective of this.

Going Forward

There you have it! I highly recommend going with the oil created by the same manufacturer for your jet ski. It just makes perfect sense and you’re only paying marginally more.
