You see the smile on their face as they zip around the yard, and you know that your work in the garage is paying off. But when it comes to maintenance, something as simple as an oil change can feel surprisingly complicated. You’ve probably found yourself wondering, “Am I using the right stuff?”
You’re not alone. Using the wrong oil can do more than just hurt performance; it can cause real, expensive damage to that little engine. We promise this guide will cut through all the confusion. We’re going to give you the exact information, pro tips, and step-by-step instructions you need to confidently choose the correct can-am ds 90 oil type and perform the service yourself.
In this article, you’ll learn exactly which oil to buy, why it matters so much, how to perform a flawless oil change, and how to avoid the common mistakes many people make. Let’s get those hands dirty and keep that DS 90 ripping.
Why the Right Can-Am DS 90 Oil Type is Non-Negotiable
It’s easy to think “oil is oil,” but for a high-revving, air-cooled ATV engine like the one in the DS 90, that’s a dangerous assumption. The engine oil is the lifeblood of your machine, and using the correct formula is crucial for three key reasons.
Engine Protection and Longevity
The primary job of engine oil is to lubricate. It creates a microscopic film between moving metal parts—like the piston and cylinder wall—preventing them from grinding each other into dust. The right can-am ds 90 oil type contains specific additives that stand up to the intense heat and shear forces inside a small engine, ensuring that protective film never breaks down.
Using the wrong oil, especially standard car oil, can lead to premature wear, engine overheating, and ultimately, catastrophic failure. This is one of the most significant benefits of can-am ds 90 oil type specific formulas; they are designed for the unique demands of a powersports engine.
Optimal Performance and Cooling
Did you know oil is also a critical part of your ATV’s cooling system? As it circulates, it pulls heat away from the hottest parts of the engine, like the piston crown. An oil that’s too thick (high viscosity) won’t flow quickly enough to cool effectively, while one that’s too thin won’t provide adequate lubrication when hot.
The manufacturer’s recommended viscosity ensures the engine runs at its peak, delivering the power and throttle response you expect. It’s a simple step that has a direct impact on performance on the trail.
Clutch and Transmission Health
Unlike cars, many ATVs and motorcycles use the same oil to lubricate the engine, clutch, and transmission. While the DS 90 uses a CVT (Continuously Variable Transmission) and doesn’t have a manual wet clutch, it’s still best practice to use a powersports-specific oil.
Many automotive oils contain “friction-modifying” additives designed to improve fuel economy. These same additives can cause issues in powersports gearboxes and transmissions. Sticking to a JASO MA/MA2 rated oil is the safest bet to ensure all internal components get the lubrication they need without harmful side effects.
The Official Word: What Oil Does a Can-Am DS 90 Take?
Alright, let’s get down to brass tacks. When you’re standing in the aisle at the auto parts store, what should you be looking for? This can-am ds 90 oil type guide will make it simple.
The Manufacturer’s Recommendation
Can-Am (BRP) officially recommends using their own XPS 4-Stroke Synthetic Blend Oil (5W-40). This oil is specifically formulated for the Rotax engines used in their vehicles, including the DS 90. It’s the guaranteed, no-questions-asked right choice.
However, you are not locked into using only the XPS brand. As long as you meet the specifications, other high-quality oils will work perfectly.
Understanding Oil Specifications
If you opt for another brand, you need to match two key specs: viscosity and service rating.
- Viscosity: The recommended viscosity for the Can-Am DS 90 is SAE 5W-40. The “5W” refers to its flow characteristics when cold (the ‘W’ stands for Winter), and the “40” refers to its thickness when the engine is at operating temperature. Using a 5W-40 ensures easy starting in colder weather and robust protection when the engine is hot.
- Service Rating: Look for an oil that meets or exceeds an API SL or JASO MA/MA2 rating. The API (American Petroleum Institute) rating ensures it meets modern standards for protection. The JASO (Japanese Automotive Standards Organization) rating is even better, as it certifies the oil is suitable for powersports applications and is free of harmful friction modifiers.
Synthetic vs. Conventional Oil
You’ll see both synthetic and conventional oils on the shelf. For an air-cooled engine that works hard like the one in the DS 90, synthetic or a synthetic blend is highly recommended.
Synthetic oil offers superior thermal stability, meaning it resists breaking down under high heat. It also provides better cold-weather performance and contains stronger detergent packages to keep your engine cleaner internally. The extra couple of dollars per quart is cheap insurance for your engine’s health.
Your Complete Can-Am DS 90 Oil Type Care Guide: A Step-by-Step Oil Change
Now for the fun part! Knowing how to can-am ds 90 oil type service is done will save you time and money. It’s a simple job that any DIYer can tackle with basic tools. Follow these best practices for a smooth process.
Tools and Supplies You’ll Need
Gather everything before you start to avoid running around with an ATV full of no oil.
- Fresh Engine Oil (approx. 1 US quart of 5W-40 synthetic or blend)
- Oil Drain Pan
- Socket Wrench Set (you’ll likely need a 17mm socket for the drain plug)
- Funnel
- Clean Rags or Shop Towels
- Nitrile Gloves
- A new drain plug crush washer (highly recommended to prevent leaks)
Step-by-Step Oil Change Instructions
- Warm Up the Engine: Start the DS 90 and let it run for 2-3 minutes. This warms the oil, thinning it out so it drains completely and carries suspended contaminants with it. Don’t get it scorching hot, just warm to the touch.
- Position the ATV: Park the DS 90 on a level surface. This is crucial for an accurate oil level reading later.
- Locate and Clean the Drain Plug: The drain plug is on the bottom of the engine case. Wipe the area around it with a clean rag to prevent any dirt from falling into the engine.
- Drain the Old Oil: Place your drain pan directly under the plug. Using your socket wrench, turn the drain plug counter-clockwise to loosen it. Once it’s loose, finish unscrewing it by hand. Be ready for the oil to flow out. Pro Tip: Apply slight upward pressure on the plug as you unscrew the last few threads to prevent oil from gushing onto your hand.
- Clean the Strainer/Screen: The DS 90 has an oil strainer screen behind a cap near the drain plug (check your owner’s manual for the exact location). Remove the cap (often held by two small bolts) and carefully pull out the screen. Clean it thoroughly with a brake cleaner or solvent and a soft brush, let it dry, and inspect it for any metal shavings (a bad sign).
- Reinstall the Plug and Strainer: Once the oil has completely drained to a slow drip, wipe the drain plug clean. Install a new crush washer. Reinstall the drain plug and tighten it snugly—don’t overtighten! The spec is usually around 15-18 ft-lbs. Reinstall the clean oil strainer and its cap.
- Refill with New Oil: Locate the oil fill cap/dipstick on the side of the engine. Unscrew it and place a clean funnel in the opening. The Can-Am DS 90 oil capacity is approximately 0.9 liters (0.95 US quarts). Start by adding about 0.8 liters. Do not pour the whole bottle in at once.
- Check the Oil Level: Reinsert the dipstick without screwing it in—just let it rest on the threads. Pull it out, wipe it clean, and insert it again to get an accurate reading. The oil level should be between the upper and lower marks. Add small amounts of oil as needed until it’s at the full mark.
- Final Check: Screw the dipstick cap back in securely. Start the engine and let it run for about a minute to circulate the new oil. Shut it off, wait another minute for the oil to settle, and re-check the level one last time. Top off if necessary and check for any leaks around the drain plug.
Common Problems with Can-Am DS 90 Oil Type and How to Avoid Them
Even a simple job can go wrong. Here are some common mistakes we see at the shop and how you can easily avoid them, ensuring your can-am ds 90 oil type care guide is a success.
Using the Wrong Oil
The most common mistake is grabbing any old car oil off the shelf. As we discussed, automotive oils can lack the shear stability and may contain friction modifiers that are bad for your ATV. Always double-check that you have a 5W-40 powersports-specific oil rated for API SL or JASO MA/MA2.
Overfilling or Underfilling
Too much oil is just as bad as too little. Overfilling can cause the oil to foam up, leading to a loss of oil pressure and poor lubrication. It can also blow out seals. Underfilling is just asking for engine seizure. Always fill slowly and check the level multiple times using the dipstick.
Overtightening the Drain Plug
It’s tempting to crank down on the drain plug to prevent leaks, but this can strip the threads in the aluminum engine case—a very expensive repair. Use a torque wrench if you have one, or just tighten it until it’s snug. The new crush washer is what creates the seal, not brute force.
Forgetting the Crush Washer
That little copper or aluminum washer is a one-time-use item. It’s designed to crush slightly when tightened to form a perfect seal. Reusing an old one is the number one cause of a leaky drain plug. They cost less than a dollar; always replace it.
Eco-Friendly and Sustainable Can-Am DS 90 Oil Type Practices
Being an off-roader means respecting the environment we love to ride in. Handling oil responsibly is a big part of that. These eco-friendly can-am ds 90 oil type tips are easy to follow.
First, always use a drain pan and a funnel to prevent spills. A single drop of oil can contaminate a huge amount of groundwater. If you do have a small spill, clean it up immediately with an absorbent material like cat litter, not by hosing it down.
Second, and most importantly, never dump used motor oil down a drain, on the ground, or in the trash. It is highly toxic. Pour your used oil from the drain pan back into the empty oil bottle.
Nearly all auto parts stores (like AutoZone, O’Reilly, Advance Auto Parts) and many municipal recycling centers accept used motor oil for free. It’s an easy, responsible, and sustainable can-am ds 90 oil type practice that protects our trails and waterways for future generations of riders.
Frequently Asked Questions About Can-Am DS 90 Oil Type
How often should I change the oil in a Can-Am DS 90?
For a youth ATV, it’s best to follow the owner’s manual. A good general rule is to change the oil after the initial break-in period (around 10-20 hours) and then every 6 months or 50 hours of use, whichever comes first. If you ride in very dusty or muddy conditions, change it more frequently.
Can I use 10W-40 oil instead of 5W-40?
In warmer climates where you never ride below freezing, you can generally get away with using a 10W-40 powersports oil. However, 5W-40 provides better protection during cold starts, which is when most engine wear occurs. Sticking with the recommended 5W-40 is the best practice.
What happens if I use car oil in my DS 90?
While it might seem to work fine for a short time, you risk long-term damage. The biggest risks are accelerated engine wear due to the oil breaking down under heat and potential issues with internal components not designed for the friction modifiers found in many passenger car motor oils. It’s simply not worth the risk to save a few dollars.
You’ve now got all the knowledge you need to tackle this essential maintenance task with the confidence of a pro. Choosing the right can-am ds 90 oil type and changing it regularly is the single best thing you can do to ensure that little four-wheeler provides years of reliable fun.
So grab your tools, put on some tunes in the garage, and get it done. Your young rider—and your wallet—will thank you for it. Happy wrenching, and ride safe!
