In this complete can am outlander 650 motor oil guide, we’ll walk you through choosing the perfect oil, a detailed step-by-step change process, and the common pitfalls to avoid. Let’s get your Outlander running better than ever.
Why the Right Can-Am Outlander 650 Motor Oil is Non-Negotiable
Think of your ATV’s engine oil as more than just a lubricant. It’s a complex fluid engineered to perform several critical jobs under extreme heat and pressure, especially in a hard-working V-Twin engine like the one in your Outlander 650.
Getting this choice right is crucial for the health and longevity of your machine. The benefits of can am outlander 650 motor oil that meets the manufacturer’s specs are huge, and skimping here is a classic case of being penny-wise and pound-foolish.
The Four Critical Jobs of Your Engine Oil
- Lubrication: This is the most obvious job. A high-quality oil creates a protective film between moving parts like the piston, cylinder walls, and bearings, preventing metal-on-metal contact and catastrophic wear.
- Cooling: Oil circulates through the engine, carrying away a significant amount of heat from critical components like the bottom of the pistons—areas your coolant can’t reach.
- Cleaning: Modern oils contain detergents and dispersants. These additives clean away carbon deposits and suspend harmful contaminants, carrying them to the oil filter to be trapped.
- Protection: Your oil contains anti-corrosion agents that protect internal engine surfaces from rust and chemical breakdown, especially during periods of storage.
Using the wrong oil can lead to clutch slippage (a huge issue with wet clutches), increased engine wear, overheating, and sludge buildup. It’s a simple maintenance task that pays massive dividends in reliability.
Decoding the Specs: Choosing the Best Oil for Your Outlander 650
Walking into an auto parts store can be overwhelming. You’ll see shelves of different brands, weights, and types. Luckily, Can-Am makes it simple. Here’s exactly what you need to look for in a can am outlander 650 motor oil guide.
Oil Viscosity: What Does 5W-40 Mean?
Your owner’s manual specifies a 5W-40 synthetic oil. This number, called viscosity, is a measure of the oil’s thickness or resistance to flow.
- The “5W” stands for Winter. It indicates how easily the oil flows at cold temperatures. A lower number is better for cold starts, ensuring oil gets to vital parts quickly.
- The “40” represents the oil’s viscosity at normal engine operating temperature (100°C / 212°F). It needs to be thick enough to provide protection under high heat and load.
Using a 5W-40 ensures your engine is protected whether you’re starting it on a frosty morning or pushing it hard on a hot summer day.
Synthetic vs. Conventional: No Contest
For a high-performance engine like the Rotax 650, synthetic oil is a must. While more expensive than conventional (petroleum-based) oil, its benefits are undeniable.
Synthetic oil is engineered in a lab for purity and uniformity. It resists thermal breakdown at high temperatures far better, flows better in the cold, and contains superior cleaning additives. This means a cleaner, better-protected, and longer-lasting engine.
The All-Important JASO MA2 Rating
This is the spec that trips up many DIYers. Your Outlander has a wet clutch, which means the engine, transmission, and clutch all share the same oil. Car oils contain friction modifiers that can make your clutch slip, leading to power loss and premature wear.
Look for an oil that is rated JASO MA, MA1, or MA2. This certification ensures the oil is formulated to work correctly with your wet clutch system. Never use an oil marked “Energy Conserving” in your ATV.
Our Top Oil Recommendations
- BRP XPS 4-Stroke Synthetic Oil (5W-40): This is the OEM (Original Equipment Manufacturer) oil. You can never go wrong using the oil the machine was designed with.
- Rotella T6 Full Synthetic (5W-40): A long-time favorite in the powersports community. It’s technically a “heavy-duty diesel” oil, but it carries the JASO MA/MA2 rating, making it perfectly safe and highly effective for your Outlander.
- Mobil 1 Racing 4T (10W-40): While a slightly different weight, this is another excellent, widely available powersports-specific synthetic oil that meets the JASO MA2 spec and works great in most conditions. Always check your manual for temperature range recommendations.
Your Step-by-Step Can Am Outlander 650 Motor Oil Change Guide
Alright, let’s get our hands dirty. This is one of the most satisfying DIY jobs you can do. Follow these instructions on how to can am outlander 650 motor oil change, and you’ll be done in under an hour. Safety first—make sure your ATV is on a level surface and the engine is cool enough to touch but still warm.
Gather Your Tools and Supplies
- Ratchet with a 17mm socket (for the drain plug)
- Oil filter wrench (cap style or strap wrench)
- Funnel
- Drain pan
- Nitrile gloves
- Shop towels or rags
- Approximately 2.1 US quarts (2 liters) of new 5W-40 synthetic oil (JASO MA2 rated)
- New oil filter (e.g., Can-Am #420256188, or a quality aftermarket equivalent from K&N, Hiflofiltro, etc.)
- New sealing washers for the drain plug
Step 1: Warm Up the Engine
Run the engine for 2-3 minutes. This warms the oil, making it flow out faster and more completely. It also helps suspend any contaminants so they drain out with the old oil.
Step 2: Drain the Old Oil
Place your drain pan under the engine. The drain plug is located on the bottom of the engine case. Using your 17mm socket, loosen the plug. Unscrew it the rest of the way by hand, being ready for the hot oil to flow out.
Let the oil drain completely for at least 10-15 minutes. While it’s draining, clean the magnetic tip of the drain plug. A small amount of fine metallic “fuzz” is normal, but large chunks could indicate a problem.
Step 3: Replace the Oil Filter
The oil filter is located on the right side of the engine. Use your oil filter wrench to loosen it. Oil will spill, so have rags ready. Unscrew it and remove it.
Take your new oil filter and apply a thin film of new oil to the rubber gasket. This ensures a good seal. Pro Tip: Pour a small amount of new oil into the new filter before installing it. This helps reduce the time the engine runs without oil pressure on the next startup.
Screw the new filter on by hand until it makes contact with the engine, then tighten it another 3/4 of a turn. Do not overtighten!
Step 4: Refill with New Oil
Install the drain plug with a new sealing washer. Tighten it to the manufacturer’s specified torque, which is typically around 18 lb-ft (25 Nm). Be very careful not to strip the threads.
Unscrew the oil dipstick/fill cap. Using a funnel, slowly add approximately 2 quarts of new oil. The manual specifies 2.1 quarts (2L), but it’s best to add 2 quarts first and then top it off.
Step 5: The Final Check
Reinstall the dipstick. Start the engine and let it run for about 30 seconds. This circulates the new oil and fills the filter. Shut it off and wait a minute for the oil to settle.
Remove the dipstick, wipe it clean, reinsert it fully, and pull it out again to check the level. It should be between the “MIN” and “MAX” marks. Add small amounts of oil as needed to bring it to the “MAX” line. Do not overfill!
Common Problems with Can Am Outlander 650 Motor Oil & How to Avoid Them
Even a simple job can go wrong. Here are a few common problems with can am outlander 650 motor oil changes and maintenance that we see all the time.
- Overfilling the Engine: More is not better! Too much oil can cause foaming, leading to a loss of lubrication and increased pressure that can blow out seals. Always fill to the “MAX” line on the dipstick and no higher.
- Stripping the Drain Plug: The engine case is aluminum, and the drain plug is steel. It’s very easy to overtighten and strip the threads. Use a torque wrench if you have one. If not, snug it up firmly but don’t use excessive force.
- Using the Wrong Oil: As we discussed, using car oil without a JASO MA2 rating is a recipe for a slipping clutch and expensive repairs. Stick to powersports-specific synthetic 5W-40.
- Forgetting the Sealing Washer: That little copper or aluminum washer is a one-time-use item. Reusing it can lead to a slow, messy leak. Always use a new one.
Advanced Care: Can Am Outlander 650 Motor Oil Best Practices
Your relationship with your engine oil doesn’t end after the change. Adopting these best practices will ensure your engine stays in top shape between services.
This can am outlander 650 motor oil care guide is about vigilance. Before every ride, do a quick walk-around. Pull the dipstick and check the oil level. It takes 30 seconds and can save you from a catastrophic failure on the trail.
Pay attention to your riding conditions. If you frequently ride in very dusty, wet, or muddy conditions, or do a lot of heavy towing, you should change your oil more often than the manual suggests. For “severe use,” cutting the service interval in half is a cheap insurance policy.
Sustainable Choices: Eco-Friendly Can Am Outlander 650 Motor Oil Disposal
Being a responsible off-roader means protecting the trails we love. Used motor oil is highly toxic and must be disposed of properly. Never, ever dump it on the ground or in the trash.
Pour your old oil from the drain pan into the empty oil bottles from your oil change. Most auto parts stores (like AutoZone, O’Reilly, or Advance Auto Parts) and many local recycling centers will accept used motor oil for free.
This simple act of finding a place for sustainable can am outlander 650 motor oil disposal is a critical part of the DIY process. It keeps our environment clean for the next generation of riders.
Frequently Asked Questions About Can Am Outlander 650 Motor Oil
How often should I change the oil on my Can-Am Outlander 650?
For a new machine, the first service is critical and usually occurs at 10 hours or 200 miles. After that, Can-Am recommends a service every 100 hours or 2,000 miles under normal use. However, we strongly recommend changing it at least once a year, regardless of mileage, or more frequently if you ride in harsh conditions.
Can I use 10W-40 oil instead of 5W-40?
In warmer climates, 10W-40 is generally acceptable as long as it is a high-quality synthetic that meets the JASO MA2 specification. However, 5W-40 provides better protection during cold starts, making it the superior all-around choice recommended by the manufacturer.
What if I accidentally put car oil in my ATV?
If you realize it immediately, do not start the engine. Drain the incorrect oil completely and refill with the proper powersports-specific oil. If you have already run the engine, you may experience clutch slippage. The best course of action is to drain it, refill with the correct oil, and hope the clutch plates have not been permanently damaged. If slippage continues, the clutch plates may need to be replaced.
Taking care of your Can-Am Outlander 650’s engine is the single most important thing you can do to ensure it’s ready for the trail whenever you are. An oil change is a simple, affordable, and rewarding task that connects you with your machine. Follow this guide, use the right products, and you’ll be rewarded with years of reliable performance.
