In this article, you’ll learn the exact tools you need, the correct procedure for draining and refilling, pro tips to avoid common mistakes, and how to do it all safely and responsibly. Let’s get those hands dirty and give your Outlander the fresh oil it deserves.

Why Regular Oil Changes are Non-Negotiable for Your Outlander 450

Before we grab the wrenches, let’s talk about the why. Understanding the benefits of how to change oil on can am outlander 450 regularly isn’t just trivia; it’s motivation to stick to your maintenance schedule and protect your investment.

Think of engine oil as the lifeblood of your ATV. It does more than just lubricate.

Lubrication: This is the most obvious job. Fresh oil creates a slick barrier between moving parts like the piston, crankshaft, and bearings, drastically reducing friction and wear. Old, broken-down oil can’t do this effectively.
Cooling: Oil carries heat away from the hottest parts of the engine, particularly the combustion chamber. As oil degrades, its ability to manage heat diminishes, leading to a hotter-running engine.
Cleaning: Your oil filter can’t catch everything. Detergents in fresh oil suspend tiny particles of metal, soot, and dirt, carrying them to the filter and preventing sludge from building up in critical passages.
Corrosion Prevention: Additives in the oil form a protective layer on internal components, shielding them from rust and corrosion caused by moisture and combustion byproducts.

Skipping oil changes is one of the fastest ways to cause premature engine wear, reduced performance, and potentially catastrophic failure. It’s a simple, inexpensive task that pays huge dividends in reliability and longevity on the trail.

Gathering Your Arsenal: Tools and Parts You’ll Need

Nothing slows down a DIY job like having to stop midway through to run to the auto parts store. A little preparation goes a long way. Here’s everything you’ll need for a smooth and successful oil change.

Required Parts:

Engine Oil: The most critical part! Your Can-Am Outlander 450 requires approximately 2.1 US quarts (2 Liters) of 5W-40 Synthetic Blend 4-stroke engine oil. We highly recommend using BRP’s own XPS oil or a high-quality, powersports-specific equivalent that is JASO MA2 rated.
Oil Filter: Always replace the filter with the oil. Get a quality replacement filter, like the OEM Can-Am filter (Part #420256188) or a trusted aftermarket brand.
New O-Rings: Your new oil filter should come with two new O-rings for the filter cover. Never reuse the old ones.
Drain Plug Sealing Washer: This is a small crush washer that ensures a leak-free seal. It’s best practice to replace it every time.

Essential Tools:

Ratchet and Socket Set: You will need an 8mm socket for the oil filter cover bolts and a 17mm socket for the engine drain plug.
Torque Wrench: This is crucial for preventing stripped bolts and oil leaks. Overtightening is a common DIY mistake.
Oil Filter Pliers or Wrench (Optional): Sometimes the old filter can be stubborn. While not always necessary, it’s good to have on hand.
Funnel: A clean funnel is essential for adding new oil without making a mess.
Oil Drain Pan: A pan with at least a 4-quart capacity will be more than enough.
Clean Rags or Paper Towels: You’ll need plenty for cleanup.
Nitrile or Latex Gloves: Used motor oil is nasty stuff. Protect your skin.

Pre-Service Prep: Setting Up for a Clean and Safe Oil Change

Proper setup is the foundation of this how to change oil on can am outlander 450 care guide. It makes the job easier, safer, and cleaner.

First, find a level surface to work on. This ensures an accurate oil level reading later and prevents your ATV from rolling.

Next, you need to warm up the engine. Start your Outlander and let it run for 3-5 minutes. Don’t get it screaming hot, just warm enough for the oil to thin out. Warm oil flows much faster and carries more suspended contaminants out with it. This is one of the most important how to change oil on can am outlander 450 tips.

Once warm, shut it off. If you have skid plates, now is the time to clean any mud or debris from around the drain plug and oil filter housing. You don’t want dirt falling into your engine.

The Main Event: A Step-by-Step Guide on How to Change Oil on Can-Am Outlander 450

Alright, tools are ready, the engine is warm, and you’re prepared. Let’s get to the core of this job. Follow these steps carefully for a perfect oil change.

Step 1: Locate and Remove the Dipstick

On the right side of the engine (as you’re sitting on it), you’ll find the yellow oil filler cap/dipstick. Unscrew and remove it completely. This helps vent the engine, allowing the old oil to drain out more smoothly.

Step 2: Position the Drain Pan and Remove the Drain Plug

Slide your oil drain pan directly under the engine. The drain plug is a 17mm bolt located on the bottom of the engine, on the left (magneto) side. It’s often recessed within the frame.

Using your 17mm socket and ratchet, turn the plug counter-clockwise to loosen it. Once it’s loose, finish unscrewing it by hand. Be prepared for the oil to start flowing as you remove the last few threads. Remember, the oil will be warm, so be careful.

Step 3: Drain the Old Oil Completely

Let the oil drain for at least 10-15 minutes. While it’s draining, inspect the drain plug. It has a magnet on the end designed to catch fine metal particles. A tiny bit of metallic “fuzz” is normal, but large shavings could indicate a bigger issue.

Wipe the drain plug magnet clean. Replace the old sealing washer with a new one. Once the oil has slowed to a very slow drip, you’re ready to reinstall the plug.

Step 4: Reinstall the Drain Plug

Thread the drain plug back in by hand to avoid cross-threading. Snug it up with your ratchet, then finish with a torque wrench. The proper torque spec is 15 lb-ft (20 Nm). Do not overtighten!

Step 5: Replace the Oil Filter

Move your drain pan under the oil filter housing, located on the right side of the engine. It’s a small, circular cover held on by three 8mm bolts.

Remove the three bolts. A small amount of oil will drip out. Gently pry the cover off. The old filter will come out with it. Note the orientation of the filter—the rubber grommet end goes into the engine first.

Using a small pick or screwdriver, carefully remove the two old O-rings from the filter cover. Clean the cover and the O-ring grooves thoroughly. Lubricate the two new O-rings with a dab of fresh engine oil and install them in their grooves.

Install the new oil filter into the engine housing (grommet side in). Place the cover back on and reinstall the three 8mm bolts. Tighten them in a star pattern to ensure the cover seats evenly. Torque them to 7 lb-ft (10 Nm).

Step 6: Add New Engine Oil

With the drain plug and filter secured, it’s time for fresh oil. Place your clean funnel into the filler hole where you removed the dipstick.

Slowly pour in 2 quarts of your new 5W-40 oil. The total capacity is 2.1 quarts (2 L), but it’s best to add 2 quarts first and then check the level. Reinstall the dipstick, screwing it all the way in.

Step 7: Check the Oil Level

Start the engine and let it run for about 30 seconds. This circulates the new oil and fills the new oil filter. Shut the engine off and wait for 1-2 minutes for the oil to settle back into the pan.

Remove the dipstick, wipe it clean with a rag, reinsert it fully, and pull it out again. The oil level should be between the “MIN” and “MAX” marks. If it’s low, add a small amount of oil at a time (about 1/4 of a quart) and recheck until it’s at the full mark. Do not overfill.

Finishing Touches and Best Practices for a Job Well Done

You’re almost there! Following these how to change oil on can am outlander 450 best practices ensures a professional-quality job.

Wipe down any spilled oil from the engine case, frame, and skid plate. This helps you spot any potential leaks later on. Give the drain plug and filter cover a final visual check to ensure they are secure and not leaking.

Eco-Friendly Oil Disposal

Now, what to do with that old oil and filter? Being a responsible rider means practicing sustainable how to change oil on can am outlander 450 maintenance. Never pour used oil on the ground or in the trash.

Pour the old oil from your drain pan into the empty new oil containers. Place the old filter in a plastic bag to prevent drips. Most auto parts stores (like AutoZone, O’Reilly, Advance Auto Parts) and local recycling centers accept used motor oil and filters for free. This is the best eco-friendly how to change oil on can am outlander 450 method.

Troubleshooting Common Problems and Pro Tips

Even a straightforward job can have hiccups. Here are some solutions to common problems with how to change oil on can am outlander 450 maintenance.

Problem: Stripped Drain Plug or Bolts. This is usually caused by overtightening. If it happens, you may need a thread repair kit (like a Heli-Coil) or, in severe cases, professional help. This is why a torque wrench is your best friend.
Problem: Oil Leak After the Change. The most common culprits are a reused drain plug washer or pinched/improperly seated O-rings on the filter cover. Double-check your work and ensure all seals are new and properly installed.
Pro Tip: Pre-fill the Filter. For an extra level of care, you can pour a small amount of new oil into the new oil filter before installing it. This helps reduce the time the engine runs with no oil pressure upon the first startup.
Pro Tip: Keep a Log. Use a small notebook or a phone app to log the date and mileage/hours of your oil change. This makes it easy to track your service intervals.
