You agree that simple maintenance, like an oil change, is the key to keeping that ATV running strong, right? The problem is, misinformation about something as basic as fluid levels can lead to costly mistakes.
We promise this guide will eliminate all the guesswork. We’re here to give you the exact numbers, the right steps, and the pro-level insights to handle this job perfectly, protecting that little engine for years of fun.
In this complete can am ds 90 oil capacity care guide, we’ll cover the precise fluid amount, walk you through a foolproof oil change, explain which oil is best, and highlight the common problems that you can easily avoid. Let’s get to it.
Why the Correct Can Am DS 90 Oil Capacity is Non-Negotiable
Before we grab the wrenches, it’s crucial to understand why this specific measurement matters so much. Engine oil in your DS 90 isn’t just a lubricant; it’s the lifeblood of the engine, performing several critical jobs at once.
Getting the oil level right ensures the engine can do its job without stress. The benefits of maintaining the correct can am ds 90 oil capacity are huge. Proper lubrication reduces friction and wear on moving parts, the oil helps dissipate heat away from the piston and cylinder, and it carries away tiny contaminants to the oil filter.
On the flip side, getting it wrong—either by overfilling or underfilling—is one of the fastest ways to cause serious, expensive damage. This isn’t just about performance; it’s about the fundamental health and longevity of the ATV’s engine.
The Official Can Am DS 90 Oil Capacity (And What It Really Means)
Let’s cut to the chase. You’re here for the number, and precision is key. For a standard oil and filter change, the Can-Am DS 90 requires a specific amount to function correctly.
Oil Capacity for a Standard Oil Change
For a routine drain and refill, the recommended can am ds 90 oil capacity is:
- 0.8 Liters (800 ml)
- 0.85 US quarts
This is the number you’ll use for 99% of your maintenance. It accounts for the oil drained from the sump and what’s held in a new oil filter. Always start with this amount, and then use the dipstick to verify the final level.
Total Capacity (After an Engine Rebuild)
It’s important to note that the total capacity of a completely dry engine (for example, after a full teardown and rebuild) is slightly higher. However, for regular maintenance, stick to the 0.8 L figure to avoid overfilling.
Your Complete Can Am DS 90 Oil Capacity Guide: A Step-by-Step Oil Change
Knowing the number is half the battle. Now, let’s walk through the process. This how to can am ds 90 oil capacity guide ensures you do the job safely and effectively. Gather your tools and let’s give that DS 90 some fresh oil.
Tools and Supplies You’ll Need
- Ratchet with a socket for the drain plug (typically 17mm, but confirm on your model)
- Oil filter wrench or pliers
- Funnel
- Oil drain pan
- Nitrile gloves
- Clean rags or shop towels
- 1 bottle (1 US quart or 1 Liter) of the correct engine oil
- New oil filter (specific to the DS 90)
- New drain plug sealing washer (highly recommended)
Step 1: Prep and Warm-Up
First, start the ATV and let it run for 2-3 minutes. Don’t get it scorching hot, just warm enough to help the old oil thin out and drain more completely. A warm engine suspends contaminants in the oil, ensuring you drain out more gunk.
Park the ATV on a level surface. This is critical for getting an accurate oil level reading later. Turn off the engine.
Step 2: Draining the Old Oil
Place your oil drain pan directly under the engine’s drain plug. Using your ratchet and socket, loosen the drain plug. Once it’s loose, finish unscrewing it by hand to control its removal and avoid dropping it into the hot oil.
Let the oil drain completely. While it’s draining, locate the oil filter. Place a rag underneath it to catch any drips and use your filter wrench to unscrew it. Let this area drain as well.
Step 3: Cleaning and Replacing
Wipe the drain plug clean and inspect the threads. Install a new sealing washer. This tiny part is cheap insurance against leaks. Clean the area around the drain plug opening on the engine case, then reinstall the drain plug and tighten it to the manufacturer’s specified torque. Do not overtighten!
Next, take your new oil filter and apply a thin film of fresh oil to the rubber gasket. This ensures a good seal. Screw the new filter on by hand until it makes contact, then give it another 1/2 to 3/4 turn. Again, don’t go overboard with tightening.
Step 4: Refilling with Precision
Unscrew the oil filler cap/dipstick. Using a clean funnel, pour in exactly 0.8 Liters (800 ml) of new oil. Pouring slowly helps prevent air pockets and spills.
Once the oil is in, replace the filler cap but don’t screw it in all the way yet.
Step 5: The Final Check
This is the most important step in our can am ds 90 oil capacity guide. Start the engine and let it run for about 30 seconds. This circulates the new oil and fills the new filter. Shut the engine off and wait about a minute for the oil to settle.
Now, remove the dipstick, wipe it clean, re-insert it fully, and pull it out again to get an accurate reading. The oil level should be between the upper and lower marks. If it’s perfect, you’re done! If it’s slightly low, add a tiny amount of oil at a time until it’s correct.
Choosing the Right Oil: Beyond Just Capacity
Pouring in the right amount of the wrong oil is still a mistake. The Can-Am DS 90’s engine is designed for a specific type of oil to provide maximum protection. Following these can am ds 90 oil capacity best practices will make a huge difference.
Understanding Oil Viscosity (5W-40 Explained)
Can-Am recommends a 5W-40 synthetic 4-stroke engine oil. The “5W” refers to its viscosity (flowability) in cold temperatures, and the “40” refers to its viscosity at operating temperatures. Using the correct viscosity ensures protection during cold starts and high-heat trail riding.
Synthetic vs. Conventional: What’s Best for the DS 90?
For small, high-revving air-cooled engines like the one in the DS 90, synthetic oil is strongly recommended. It offers superior thermal stability, better protection against breakdown, and keeps the engine cleaner. BRP’s own XPS brand is excellent, but any high-quality 5W-40 synthetic oil designed for 4-stroke ATVs will work well.
Common Problems with Can Am DS 90 Oil Capacity and How to Avoid Them
Even simple jobs have pitfalls. Here are some of the most common problems we see and how you can sidestep them for a perfect oil change every time.
The Dangers of Overfilling
Adding too much oil is just as bad as not adding enough. Excess oil gets churned by the crankshaft, creating foam. This aerated oil doesn’t lubricate properly and can lead to a catastrophic drop in oil pressure, causing overheating and severe engine damage.
The Risks of Underfilling
This one is more obvious. Too little oil means parts aren’t getting lubricated. The oil pump can suck in air, leading to oil starvation, friction, and rapid engine failure. Always double-check the level after running the engine for 30 seconds.
Using the Wrong Oil Type
Using standard car oil is a common mistake. While the DS 90 has a CVT and not a wet clutch like many other ATVs, it’s still best to use oil specifically formulated for powersports engines. These oils have additives designed for the high-stress, high-heat environment of an ATV engine.
Stripping the Drain Plug
The engine case is aluminum, and the drain plug is steel. It is very easy to overtighten the plug and strip the threads in the case, leading to a very expensive repair. Tighten it until it’s snug, and then give it a gentle final turn. If you have a torque wrench, use it!
Sustainable and Eco-Friendly Oil Change Practices
Being a responsible rider extends to how we handle maintenance. A few simple steps can make your oil change much more eco-friendly.
First and foremost, never dump used motor oil. It is highly toxic. Pour the old oil from your drain pan into the empty new oil bottle. Nearly all auto parts stores, and many local recycling centers, accept used motor oil for free.
Adopting sustainable can am ds 90 oil capacity practices is easy. Use a funnel to prevent spills that can contaminate soil and groundwater. Wiping up drips with reusable shop rags instead of disposable paper towels also reduces waste. These small actions help protect the trails and environment we all love to enjoy.
Frequently Asked Questions About Can Am DS 90 Oil Capacity
How often should I change the oil in a Can-Am DS 90?
For a new ATV, the first oil change is critical and should be done after the initial break-in period (around 10-15 hours of use). After that, a good rule of thumb is to change the oil every 6 months or every 25-50 hours of riding, whichever comes first. If you ride in very dusty or muddy conditions, change it more frequently.
What happens if I put too much oil in my DS 90?
Overfilling can cause the oil to foam, leading to poor lubrication, increased engine pressure, and potential damage to seals and gaskets. If you overfill, you must drain the excess oil before starting the engine again.
Can I use car oil in my Can-Am DS 90?
It’s not recommended. Powersports-specific oils contain different additive packages designed for the higher RPMs and operating temperatures of an ATV engine. Stick with a quality 5W-40 4-stroke synthetic ATV/motorcycle oil.
Where is the oil drain plug on a Can-Am DS 90?
The oil drain plug is located on the bottom of the engine case. It is typically the lowest bolt on the crankcase. Consult your owner’s manual for a precise diagram if you are unsure.
You’re now armed with all the knowledge needed to confidently manage your ATV’s engine oil. Knowing the correct can am ds 90 oil capacity and following these steps is one of the most impactful things you can do for the health of that machine.
Take your time, be precise, and you’ll ensure that DS 90 is ready for countless hours of fun on the trails. Stay safe out there, and happy riding!
