You’ll learn how to choose the right oil, perform a flawless oil change, and spot common problems before they become wallet-draining disasters.
Why Your DS 90’s Engine Oil is Its Lifeblood
Before we grab the wrenches, let’s talk about why this is so important. In a small, air-cooled engine like the one in the DS 90, the oil is doing much more than just lubricating parts. It’s the hardest working fluid in the whole machine.
Think of it as a multi-tool. It creates a microscopic barrier between moving metal parts, like the piston and cylinder wall, to prevent catastrophic wear. It also plays a huge role in cooling, carrying heat away from the hottest parts of the engine. Finally, it traps dirt, grime, and tiny metal shavings, holding them in suspension until you drain them out.
Understanding the full list of benefits of can am ds 90 oil changes makes the job feel less like a chore and more like the single best piece of preventative maintenance you can do. A solid can am ds 90 oil care guide is your first line of defense against engine trouble.
Choosing the Right Can-Am DS 90 Oil: Specs You Can’t Ignore
Walking into an auto parts store can be overwhelming. Walls of bottles, all with different numbers and certifications, can make you want to just grab the first one you see. Don’t do it. Using the wrong oil is one of the fastest ways to cause damage.
Understanding Viscosity: What 10W-40 Really Means
The most important spec is viscosity, which is a fluid’s resistance to flow. For the Can-Am DS 90, the manufacturer typically recommends a SAE 10W-40 powersports oil.
- The “10W” refers to the oil’s viscosity (or thickness) in cold temperatures (the “W” stands for Winter). A lower number means it flows better when cold, protecting the engine on startup.
- The “40” refers to its viscosity at normal operating temperatures. This ensures it’s thick enough to protect parts when the engine is hot and working hard.
Sticking with 10W-40 is your safest bet for all-around performance in most climates. Always check your owner’s manual to confirm the exact recommendation for your specific model year.
Synthetic vs. Conventional: Which is Best?
The next choice is between conventional, synthetic blend, and full synthetic oil. For a hard-working little ATV engine, the extra protection of a synthetic is well worth the small extra cost.
Full synthetic oils offer superior protection against heat breakdown, maintain their viscosity better over time, and contain advanced detergents to keep the engine cleaner. This means better performance and longer engine life, especially if the ATV is ridden hard in dusty or hot conditions.
Look for an oil that is specifically designed for 4-stroke ATVs or motorcycles. These oils have additive packages formulated for the high-revving, high-heat environment of a powersports engine. While the DS 90 has a CVT transmission and not a wet clutch, using a JASO MA or MA2 certified oil is still a good sign of a high-quality product built for this world.
How to Change Your Can-Am DS 90 Oil: A Step-by-Step Guide
Alright, let’s get our hands dirty. This is the core of our how to can am ds 90 oil process. Take your time, stay organized, and it’ll be a smooth job. This complete can am ds 90 oil guide will make you a pro in no time.
Tools & Supplies You’ll Need
Gather everything before you start. There’s nothing worse than having a machine with no oil in it while you run to the store for a forgotten tool.
- Fresh SAE 10W-40 4-stroke ATV oil (check capacity, usually around 0.95 US quarts / 0.9 Liters)
- A socket set with a ratchet (you’ll likely need a 17mm socket for the drain plug)
- Oil drain pan
- A funnel
- Clean rags or shop towels
- Nitrile or latex gloves
- Pliers for the dipstick (if it’s tight)
The Step-by-Step Oil Change Process
- Warm Up the Engine: Start the ATV and let it run for 3-5 minutes. This warms the oil, making it flow out much faster and carrying more contaminants with it. Don’t get it scorching hot, just warm to the touch.
- Get Situated: Park the DS 90 on a level surface. This is critical for getting an accurate oil level reading later. Locate the oil fill cap/dipstick on the right side of the engine and the drain plug on the bottom.
- Prepare to Drain: Place your drain pan directly under the drain plug. Loosen the oil fill cap/dipstick to allow air to enter as the oil drains, preventing a vacuum.
- Remove the Drain Plug: Using your 17mm socket, turn the drain plug counter-clockwise to loosen it. Once it’s loose, finish unscrewing it by hand. Be ready for the warm oil to start flowing out quickly.
- Let It Drain Completely: Give it a good 5-10 minutes to let every last drop of old oil drip out. While it’s draining, inspect the drain plug. Clean it thoroughly and check the threads for damage.
- Clean the Oil Screen: This is a key step! The drain plug is often part of a larger assembly that includes a small metal screen and a spring. Carefully remove this assembly. Spray the screen with brake cleaner and wipe it clean to remove any trapped debris.
- Reinstall the Plug: Once the screen is clean and the oil has stopped dripping, reinstall the spring, screen, and drain plug. Tighten it by hand first, then give it a final snug with the wrench. Do not overtighten! A good rule of thumb is “snug, then another quarter-turn.” Overtightening can strip the aluminum threads in the engine case.
- Refill with Fresh Oil: Place your funnel in the oil fill hole and slowly pour in the new oil. The capacity is about 0.9 liters, so add about 80% of the bottle first, then pause to check the level.
- Check the Level: Insert the dipstick but do not screw it in. Just rest the threads on top of the case. 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 until it’s perfect.
- Final Check: Reinstall the dipstick securely. Start the engine and let it run for about 30 seconds to circulate the new oil. Shut it off, wait a minute for the oil to settle, and re-check the level one last time, topping off if necessary.
Pro Tips and Best Practices for DS 90 Oil Care
Doing the oil change is great, but adopting a few good habits will elevate your maintenance game. These are some of the best can am ds 90 oil tips we can offer.
How Often Should You Change the Oil?
Your owner’s manual has the official service interval. Typically, it’s after a short break-in period (e.g., 10 hours) and then every 6 months or 50 hours of use, whichever comes first. However, we recommend adjusting this based on use. If you’re riding in extremely dusty, muddy, or wet conditions, cut that interval in half. Clean oil is cheap insurance.
Reading the Dipstick Like a Pro
Check the oil before every ride. It takes 30 seconds. Pull the dipstick and look at more than just the level.
- Color: New oil is a translucent amber. Dark brown or black oil is dirty and due for a change.
- Consistency: If the oil looks milky or like a coffee-colored milkshake, you have water in your engine. This needs to be addressed immediately by performing multiple oil changes to flush the system.
- Smell: If the oil smells strongly of gasoline, you may have a carburetor issue or stuck piston rings causing fuel to leak past into the crankcase.
Common Problems with Can-Am DS 90 Oil and How to Fix Them
Even with careful work, things can sometimes go sideways. Here are a few common problems with can am ds 90 oil changes and what to do about them.
“Help! I Stripped the Drain Plug!”
This is a heart-sinking moment. It usually happens from overtightening. If the threads in the engine case are stripped, you can’t create a seal. Your best bet is to use a thread repair kit like a Heli-Coil or have a professional mechanic do it. This is not a job for a beginner.
“I Overfilled the Oil. Now What?”
Too much oil is just as bad as too little. It can cause the oil to foam up, leading to a loss of lubrication, and the excess pressure can blow out engine seals. The fix is simple: just loosen the drain plug enough to let the excess oil drip out slowly until the level is correct on the dipstick.
Sustainable and Eco-Friendly Oil Disposal
Your responsibility doesn’t end when the new oil is in. Used engine oil is toxic and must be disposed of properly. Adopting a sustainable can am ds 90 oil disposal plan is part of being a good rider and member of the community.
Never, ever dump used oil on the ground, in the trash, or down a drain. A single oil change can contaminate a million gallons of fresh water.
The best eco-friendly can am ds 90 oil practice is to pour your old oil back into the empty new oil bottle. Seal it tightly and take it to almost any auto parts store (like AutoZone, O’Reilly, or Advance Auto Parts) or your local municipal recycling center. They will accept it for free.
Frequently Asked Questions About Can Am DS 90 OilWhat is the Can-Am DS 90 oil capacity?
The engine oil capacity for most Can-Am DS 90 models is approximately 0.95 US quarts or 0.9 Liters. However, never just dump a full bottle in. Always fill partially and use the dipstick to reach the correct level.
Can I use car oil in my Can-Am DS 90?
It is strongly discouraged. While the DS 90 doesn’t have a wet clutch like many manual ATVs, automotive oils still lack the specific anti-wear and anti-shear additives designed for the high-revving, hot-running environment of a powersports engine. Stick to a quality 4-stroke ATV/motorcycle oil.
How do I check the oil on a Can-Am DS 90 correctly?
Ensure the ATV is on level ground. Run the engine for a few minutes to warm it, then shut it off and wait a minute. Unscrew the dipstick, wipe it clean, then re-insert it until the cap rests on the top of the threads—do not screw it in. Pull it out to get your reading.
Taking care of the oil in your Can-Am DS 90 is the single most important maintenance task you can perform. It’s simple, satisfying, and ensures that little machine will be ready for adventure whenever you are.
By following this guide, you’ve learned not just the “how” but the “why” behind proper oil care. You’re equipped to keep that engine protected and performing at its best. Now get those tools out, ride safe, and keep the fun going!
