2021 Can Am Outlander 570 Oil Capacity: The Definitive DIY Guide

Let’s be honest, part of the pride in owning a machine like a Can-Am Outlander is knowing you can handle its basic maintenance yourself. But when it comes to an oil change, one simple question can cause a lot of stress: are you sure you know the exact amount of oil to put back in? Getting it wrong isn’t just a small mistake; it can lead to serious, expensive engine problems down the trail.

You’ve come to the right place. We’re going to eliminate the guesswork and give you the confidence to do this job perfectly every time. This isn’t just a number; it’s a complete walkthrough from a team that lives and breathes off-road maintenance.

In this guide, we’ll cover the precise 2021 can am outlander 570 oil capacity, why it’s so critical, the tools you’ll need, and a step-by-step process to ensure your Rotax engine stays protected and ready for whatever you throw at it.

The Straight Answer: What Is the 2021 Can Am Outlander 570 Oil Capacity?

Let’s cut right to the chase. The manufacturer-specified engine oil capacity for a 2021 Can-Am Outlander 570 is:

2.1 US quarts (2.0 liters) when changing both the engine oil and the oil filter.

Write this number down. Put it on a sticky note in your toolbox. This is your target. However, the most important tool you have isn’t a measuring cup—it’s your dipstick.

Think of the 2.1 quarts as your starting point, not the absolute final amount. Always use the dipstick for the final verification after running the engine briefly. This is one of the most crucial 2021 can am outlander 570 oil capacity best practices you can follow.

Why Getting the Oil Level Right is Non-Negotiable

You might be thinking, “What’s the big deal if I’m off by a little bit?” In a high-performance Rotax engine, “a little bit” can cause major headaches. Understanding the risks transforms this from a chore into a critical part of your machine’s health.

The Dangers of Too Little Oil (Underfilling)

This one is more obvious, but the consequences are severe. When the oil level is too low, the oil pump can suck in air, leading to a catastrophic loss of lubrication.

Increased Friction & Heat: Oil’s primary job is to reduce friction and dissipate heat. Without enough of it, metal parts grind against each other, causing temperatures to skyrocket.
Premature Engine Wear: Key components like pistons, bearings, and the camshaft will wear out incredibly fast without proper lubrication.
Engine Seizure: In the worst-case scenario, the lack of lubrication will cause parts to weld themselves together, seizing the engine completely. This is a full engine rebuild or replacement—a costly and frustrating repair.

The Sneaky Problems of Too Much Oil (Overfilling)

Many riders think adding a “little extra for good measure” is a good idea. It’s not. Overfilling is just as damaging, though the symptoms can be more subtle at first. This is one of the most common problems with 2021 can am outlander 570 oil capacity maintenance.

Oil Foaming (Aeration): When the oil level is too high, the engine’s crankshaft can whip the oil into a froth, like a blender making a milkshake. Aerated oil is full of air bubbles and cannot lubricate properly.
Blown Seals and Gaskets: Too much oil increases the pressure inside the crankcase. This pressure has to go somewhere, and it often pushes its way out through the weakest points—your engine’s seals and gaskets—causing messy and persistent leaks.
Reduced Performance: That same internal pressure creates drag on the engine’s rotating parts, robbing your ATV of horsepower and making the engine feel sluggish.

Your Toolkit: Everything You Need for a Perfect Oil Change

Before you get your hands dirty, gather everything you need. Having the right tools makes the job smoother, faster, and safer. Here’s your checklist.

Essential Tools & Supplies

Ratchet Wrench and Socket Set: You’ll need the correct size for the drain plug (typically 17mm or 18mm on a Can-Am).
Oil Filter Wrench or Pliers: A cap-style wrench that fits the filter is best to avoid crushing it.
Torque Wrench: Highly recommended. This is the only way to be sure you don’t over-tighten and strip the drain plug.
Funnel: A clean funnel is essential for adding new oil without making a mess.
Oil Drain Pan: Get one large enough to hold at least 3-4 quarts to avoid overflows.
Clean Rags or Shop Towels: You’ll need plenty for cleanup and wiping down surfaces.
Nitrile Gloves: Protect your hands from used oil.

The Right Oil and Filter

Engine Oil: The 2021 Outlander 570 calls for a 5W-40 synthetic blend or full synthetic powersports oil. We strongly recommend using BRP’s XPS brand or a high-quality alternative that is rated JASO MA2. The JASO MA2 rating is critical because it’s designed for wet clutch systems like the one in your ATV.
Oil Filter: Always use a new, high-quality oil filter. The OEM BRP filter (Part #420956744) is a perfect choice, but reputable aftermarket brands like K&N or Hiflofiltro also make compatible options.
New Drain Plug Sealing Washer: Don’t reuse the old one! A new washer ensures a leak-free seal.

How to: The Step-by-Step 2021 Can Am Outlander 570 Oil Capacity Guide

Alright, you’ve got your tools and your confidence. Let’s walk through the process. Follow these steps carefully for a flawless oil change.

Warm Up the Engine: Start your Outlander and let it run for 3-5 minutes. This warms the oil, making it thinner and allowing it to drain out more completely, taking suspended contaminants with it. Don’t get it scorching hot, just warm to the touch.
Position and Prepare: Park the ATV on a level surface. This is crucial for an accurate oil level reading later. Slide your oil drain pan directly under the engine’s drain plug.
Remove the Drain Plug: Using your ratchet and the correct socket, loosen and remove the engine oil drain plug. Be prepared for the warm oil to start flowing immediately. Let the oil drain completely, which may take 5-10 minutes.
Replace the Oil Filter: While the oil drains, locate the oil filter. Place some rags underneath it to catch any drips. Use your filter wrench to loosen and remove the old filter.
Prep the New Filter: Take your new oil filter and dab a small amount of new, clean engine oil on the rubber gasket. This ensures a good seal and prevents the gasket from bunching up. Screw the new filter on by hand until it makes contact, then give it another 3/4 turn. Do not over-tighten!
Reinstall the Drain Plug: Once the old oil has slowed to a drip, wipe the drain plug area clean. Install the new sealing washer on the drain plug. Screw it in by hand, then use your torque wrench to tighten it to the manufacturer’s specification (check your owner’s manual, but it’s typically around 18-22 ft-lbs). This prevents leaks and stripped threads.
Add the New Oil: Now for the main event. Place your clean funnel in the oil fill hole. Slowly pour in about 1.8 quarts of your new 5W-40 oil. By adding slightly less than the full capacity, you prevent accidental overfilling.
The Critical Final Check: Reinstall the oil fill cap/dipstick. Start the engine and let it run for about 30-60 seconds. This circulates the new oil and fills the new filter. Shut the engine off and wait 2-3 minutes for the oil to settle back into the pan.
Top Off to the Full Mark: 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 near the “add” mark. Slowly add small amounts of oil, checking the dipstick after each addition, until the level is perfectly at the “full” mark. You’ll likely end up using the full 2.1 quarts.

Eco-Friendly and Sustainable Oil Change Practices

Being a responsible rider extends to how we handle our maintenance. Following a sustainable 2021 can am outlander 570 oil capacity process is easy and important for protecting the trails we love.

Used motor oil is a hazardous material. Never, ever dump it on the ground, in a drain, or in your household trash. It’s incredibly harmful to the environment.

The best practice for eco-friendly 2021 can am outlander 570 oil capacity maintenance is to pour your used oil from the drain pan into a sealed container (like the empty oil bottles from your new oil). Take the used oil and the old filter to any auto parts store (like AutoZone, O’Reilly, or Advance Auto Parts) or a local recycling center. They will almost always accept it for free and ensure it’s recycled properly.

Frequently Asked Questions About 2021 Can Am Outlander 570 Oil Capacity

What kind of oil does a 2021 Can-Am Outlander 570 take?

It requires a 5W-40 synthetic or synthetic blend powersports engine oil that is specifically rated JASO MA2. This rating ensures it is compatible with the wet clutch system. BRP’s XPS oil is the factory recommendation, but other high-quality brands meeting these specs are also suitable.

How often should I change the oil in my Outlander 570?

Always consult your owner’s manual for the official service intervals. A general rule is after the initial 10-hour break-in period, and then every 100 hours, 1,860 miles (3,000 km), or 12 months, whichever comes first. If you ride in extremely dusty, muddy, or wet conditions, you should change it more frequently.

Do I really need to change the oil filter every time?

Yes, 100% yes. The oil filter traps harmful metal shavings and contaminants. Leaving an old, clogged filter in place means your brand new oil will immediately become contaminated and won’t be able to flow properly, defeating the purpose of the oil change.

What happens if I accidentally put 3 quarts of oil in my Outlander 570?

If you significantly overfill it, do not start the engine. The excess pressure can cause immediate damage. You will need to drain out the excess oil. Loosen the drain plug and let some oil out until the level on the dipstick is correct. If you’ve already run the engine, check for any new leaks around seals and gaskets.

You now have a complete 2021 can am outlander 570 oil capacity care guide. Knowing the exact capacity, understanding why it matters, and following the right steps empowers you to take the best possible care of your machine.

Tackling your own maintenance is one of the most rewarding parts of being an off-roader. You save money, learn more about your machine, and gain the peace of mind that the job was done right. Now, get out there and hit the trails with confidence!
