Can-Am Outlander 450 Oil Change: The Ultimate DIY Guide For Peak

Let’s be honest, the whole reason you own a Can-Am Outlander 450 is to push it to its limits on the trail, through the mud, and over whatever obstacle comes next. But that hard-charging performance depends entirely on what’s happening inside that Rotax engine. The single most important piece of maintenance you can perform is a regular oil change.

We know the thought of wrenching on your own rig can be intimidating, or maybe you’re just looking for a better process. That’s why we’re here. This guide promises to walk you through a complete can am outlander 450 oil change with the confidence of a seasoned pro.

You’ll learn not just the basic steps, but the critical ‘why’ behind them, the pro tips that prevent messy disasters, and the best practices to keep your Outlander’s engine bulletproof for years to come. Let’s get those hands dirty.

Why a Regular Oil Change is Non-Negotiable for Your Outlander 450

Skipping or delaying an oil change is one of the fastest ways to sideline your ATV. The engine oil in your Outlander is its lifeblood, and understanding the benefits of can am outlander 450 oil change maintenance will make you never want to miss one again.

Engine Lubrication and Cooling

Fresh oil creates a slick, protective film over critical moving parts like the piston, crankshaft, and valve train. This film drastically reduces friction, which in turn reduces heat and wear.

As oil circulates, it also pulls heat away from the combustion chamber, playing a vital role in keeping your engine’s temperature in the optimal range, especially during slow, technical crawls or high-RPM runs.

Removing Harmful Contaminants

Your oil filter is great, but it can’t catch everything. Over time, engine oil becomes saturated with microscopic metal shavings, dirt that gets past the air filter, and combustion byproducts.

Draining this dirty, contaminated oil removes these abrasive particles before they can cause premature wear and sludge buildup, effectively flushing the engine clean from the inside out.

Maximizing Engine Life and Performance

It’s simple: a clean, well-lubricated engine is a happy engine. It runs smoother, responds quicker, and delivers the full power you expect from a Rotax motor.

Consistent oil changes are the cheapest insurance you can buy for your ATV’s longevity, preventing costly internal damage and ensuring you spend more time on the trail and less time in the shop.

Gathering Your Tools and Parts: The Essential Checklist

Walking into the garage prepared is half the battle. Having the right tools and parts on hand makes the job smooth, clean, and efficient. Here’s exactly what you’ll need for your can am outlander 450 oil change.

The Right Oil and Filter

Engine Oil: Your Outlander 450 requires approximately 2.1 US quarts (2.0 Liters) of 5W-40 synthetic blend oil. The BRP-recommended choice is XPS 5W-40 Synthetic Blend 4T oil. Crucially, ensure any oil you use is rated JASO MA to be compatible with your wet clutch system.
Oil Filter: Stick with a quality OEM or equivalent filter. The BRP OEM part number is typically 420256188. Using a quality filter is non-negotiable for proper filtration.
Sealing Rings/Washers: Your oil change kit should come with new O-rings for the filter cap and a new crush washer for the drain plug. Never reuse old ones!

Essential Tools for the Job

Ratchet Set: You’ll need sockets, primarily an 8mm for the skid plate bolts and a 17mm for the engine drain plug.
Torque Wrench: This is a must-have tool. Over-tightening the drain plug can strip the threads in your engine case, leading to a very expensive repair.
Oil Filter Wrench: A cap-style wrench that fits the end of the filter is ideal for easy removal and installation. A strap wrench can also work in a pinch.
Drain Pan: Get one with at least a 4-quart capacity to avoid overflows.
Funnel: A clean funnel is essential for adding new oil without making a mess.
Nitrile Gloves and Shop Towels: Keep your hands clean and be ready to wipe up any drips.

The Complete Can-Am Outlander 450 Oil Change Guide: Step-by-Step

Alright, you’ve got your gear. Now it’s time to get to work. This detailed how to can am outlander 450 oil change process will guide you through every action, ensuring nothing is missed.

Warm Up the Engine: Start your Outlander and let it run for 3-5 minutes. This warms the oil, lowers its viscosity, and allows it to drain faster and more completely, carrying more contaminants out with it. Don’t get it scorching hot, just warm to the touch.
Prepare Your Workspace: Park the ATV on level ground. This is critical for an accurate oil level reading later. A level surface also prevents your drain pan from sliding or tipping.
Access the Drain Plug: Using your 8mm socket, remove the bolts holding the plastic engine skid plate. While there might be an access hole, removing the whole plate makes the job much cleaner and gives you better visibility.
Drain the Old Oil: Position your drain pan directly under the engine drain plug (it’s the 17mm bolt on the bottom of the engine). Loosen the plug with your ratchet, then finish removing it by hand to avoid dropping it in the hot oil. Let the oil drain completely for at least 10-15 minutes.
Inspect and Clean the Drain Plug: While the oil drains, wipe the drain plug clean and remove the old crush washer. The plug is magnetic and will likely have some fine metallic fuzz on it—this is normal. A large amount of shavings or chunks is a sign of a bigger problem.
Remove the Old Oil Filter: Locate the oil filter housing on the side of the engine. Place some shop towels underneath it to catch drips. Use your oil filter wrench to loosen and remove the old filter. Be ready, as a little more oil will spill out.
Install the New Filter: Take a dab of new, clean engine oil and smear it on the rubber O-ring gasket of the new oil filter. This ensures a proper seal and prevents the gasket from binding. Screw the new filter on by hand until it’s snug, then give it an additional 1/4 to 1/2 turn. Do not over-tighten!
Reinstall the Drain Plug: Place the new crush washer on the drain plug. Thread it back into the engine by hand to prevent cross-threading. Use your torque wrench to tighten it to the manufacturer’s specification, which is typically around 18 ft-lbs (25 Nm). Always verify this spec in your owner’s manual.
Add New Engine Oil: Remove the oil filler cap/dipstick. Place your funnel and slowly pour in about 1.8 quarts of new oil. Adding it all at once can cause it to overflow.
Check the Oil Level: Reinstall the filler cap. Start the engine and let it run for 30 seconds to circulate the new oil and fill the filter. Shut it off and wait a minute for the oil to settle. Remove the dipstick, wipe it clean, re-insert it fully, and pull it out again to check the level. Add small amounts of oil as needed until it reaches the ‘FULL’ mark. Do not overfill.
Final Checks and Cleanup: With the oil level correct, start the engine again and carefully inspect the drain plug and oil filter for any leaks. If all is dry, reinstall the skid plate. You’re done!

Common Problems and Pro Tips for a Flawless Oil Change

Even a straightforward job can have hiccups. This section covers some common problems with can am outlander 450 oil change procedures and provides pro-level tips to help you execute it perfectly every time. These are the details that make up the best can am outlander 450 oil change best practices.

Stripped Drain Plug? Here’s What to Do

A stripped drain plug is a DIYer’s nightmare. It’s almost always caused by over-tightening. If it happens, don’t panic. You can often fix it with a thread repair kit like a Heli-Coil or, for a simpler fix, an oversized, self-tapping drain plug. If you’re not comfortable with this, it’s time to call a professional.

The Danger of Over-Tightening

We can’t stress this enough: use a torque wrench. Too loose, and the drain plug or filter can vibrate off, dumping your oil on the trail and seizing your engine. Too tight, and you risk stripping threads or cracking the filter housing. The small investment in a torque wrench saves you from massive headaches.

Spilling Oil and Making a Mess

To prevent oil from running down the side of the engine when removing the filter, you can form a small ‘chute’ out of aluminum foil and place it underneath the filter to guide the oil directly into your drain pan. It’s a simple trick that saves a lot of cleanup time.

Eco-Friendly and Sustainable Can-Am Outlander 450 Oil Change Practices

As off-roaders, we have a responsibility to protect the trails and environment we love. A sustainable can am outlander 450 oil change is easy to do and makes a huge difference.

Proper Disposal of Used Oil and Filters

Used motor oil is highly toxic and illegal to dump. Never pour it down the drain, on the ground, or in the trash. Funnel your used oil from the drain pan into the empty oil containers you just used.

Nearly all auto parts stores (like AutoZone, O’Reilly, etc.) and many local recycling centers will accept your used motor oil and oil filters for free. It’s a simple, responsible final step to your eco-friendly can am outlander 450 oil change.

Frequently Asked Questions About the Can-Am Outlander 450 Oil Change

How often should I change the oil on my Outlander 450?

The owner’s manual suggests a schedule based on miles or hours, often around 100 hours for normal use. However, for hard off-road use—involving deep water, thick mud, or extreme dust—we at FatBoysOffroad recommend cutting that interval in half. Changing it every 25-50 hours is cheap insurance for a machine that gets pushed hard.

What kind of oil does a Can-Am Outlander 450 take?

The recommended oil is a 5W-40 synthetic blend specifically designed for powersports engines. The most critical factor is that the oil is JASO MA certified. This certification ensures it has the right frictional properties for the wet clutch system in your Outlander’s transmission, which shares the engine oil.

How much oil does a Can-Am Outlander 450 hold?

The total oil capacity is approximately 2.1 US quarts (2.0 Liters). However, you should always start by adding slightly less and then use the dipstick to bring the level up to the full mark. This prevents overfilling, which can cause oil foaming and pressure issues.

Can I use regular car oil in my ATV?

No, you should never use standard automotive oil in your Outlander 450. Most car oils contain friction modifiers that can cause the wet clutch in your ATV’s transmission to slip and burn out, leading to a major and costly repair.

Your Outlander is Ready to Rip: Final Thoughts
