Maintaining Your Can-Am Outlander 800: A Comprehensive Fluid Guide
Keeping your Can-Am Outlander 800 running smoothly is paramount for enjoying those off-road adventures. A critical aspect of this maintenance is using the correct fluids in your drivetrain and engine. Over the years, BRP (Bombardier Recreational Products), the manufacturer of Can-Am ATVs, has updated its recommendations, leading to some confusion amongst owners. This guide aims to demystify the fluid requirements for your 2009 Outlander 800, ensuring you use the right products for optimal performance and longevity.
Understanding Drivetrain Fluids: Gear Oil and Differential Fluid
Your Outlander 800's drivetrain, comprising the gearbox (transmission) and differentials (front and rear), requires specific lubrication to handle the immense stresses of off-road riding. Historically, BRP introduced separate chaincase oil for gearboxes and differential fluid for differentials. However, their recommendations have evolved, particularly with the introduction of GL5-rated differential fluids that are now also suitable for the transmission.
Gearbox (Transmission) and Rear Differential Fluid
The rear differential and the transmission on your Outlander 800 are subjected to the most significant abuse. Due to this increased workload, BRP specifically recommends using a 75W-140 gear oil for these components. This heavier viscosity oil provides superior protection under high load and temperature conditions, preventing premature wear in these vital areas. It's crucial to use a fluid that meets or exceeds the GL-5 specification for these applications.
Front Differential Fluid
The front differential, while still important, does not endure the same level of stress as the rear differential and transmission. Consequently, BRP advises using a 75W-90 gear oil for the front differential. This slightly lighter viscosity is perfectly adequate for the front end's demands and ensures smooth operation without unnecessary drag.
Fluid Capacities: Precision is Key
Getting the fluid levels right is just as important as using the correct type of oil. Overfilling can lead to increased pressure, potentially blowing out seals and causing leaks, while underfilling will result in inadequate lubrication and accelerated wear.
Front Differential Fluid Capacity
The front differential on your Outlander 800 requires approximately 500 ml of 75W-90 gear oil. To accurately check the level, fill the differential until the fluid just begins to trickle out of the fill hole. This indicates the correct level has been reached.
Rear Differential Fluid Capacity
The rear differential is where things get a bit more specific. BRP's recommendations have changed over time. Initially, they suggested only 250 ml for the rear differential. However, the updated recommendation is to use precisely 300 ml of 75W-140 gear oil. It is important to note that the fluid should not trickle out of the fill hole; it should fill up to that point. The rear differential builds more pressure than the front, and overfilling by even a small amount can cause significant problems. Always stick to the 300 ml capacity for the rear differential.
| Component | Recommended Oil Grade | Capacity |
|---|---|---|
| Transmission (Gearbox) | 75W-140 (GL-5) | 300 ml |
| Rear Differential | 75W-140 (GL-5) | 300 ml |
| Front Differential | 75W-90 (GL-5) | 500 ml |
Engine Oil: The Heart of Your Outlander
When it comes to the engine oil for your 2009 Outlander 800, the good news is that you have a wide range of excellent options. Unlike some high-performance motorcycles that require specific additives found only in motorcycle-specific oils, the Rotax engines used in Can-Am ATVs are designed to perform exceptionally well with high-quality automotive engine oils. Therefore, any full synthetic car oil will be perfectly suitable. Brands like Castrol Edge, Mobil 1, or Valvoline are all excellent choices.
Why Full Synthetic?
Full synthetic oils offer superior performance characteristics compared to conventional oils. They provide better thermal stability, resist breakdown at high temperatures, offer enhanced wear protection, and maintain their viscosity more effectively across a wider temperature range. This translates to a healthier engine, longer oil life, and consistent performance, whether you're tackling muddy trails or long-distance rides.
Viscosity and Specifications
While the specific viscosity recommendation can vary slightly depending on the ambient temperatures you typically ride in, a common and versatile choice for many 4-stroke engines is 10W-40 or 20W-50. Always check your owner's manual for the precise viscosity recommended for your specific climate. The key is to use a full synthetic oil that meets the API (American Petroleum Institute) service classification appropriate for your engine (often API SN or newer).
Tips for a Smooth Fluid Change
Changing your drivetrain fluids can seem daunting, but with a few tricks, it can be a straightforward process. Many owners find that removing the floorboards provides the best access to the drain and fill plugs for the transmission and rear differential.
A Clever Trick for Reinstalling Plugs
One common challenge is getting the drain plug back into its hole, especially in tight spaces. A resourceful tip involves using a small, strong magnet. Place the drain plug onto the magnet, point it in the correct direction, and then position the magnet near the drain hole. You can then carefully manoeuvre the plug into place with the magnet, making it much easier to start threading it in with your fingers. This simple trick can save a lot of frustration and time.
Outlander 400s and Gear Oil
Regarding whether Outlander 400 models have gear oil, the answer is yes. Similar to the larger displacement models, the Outlander 400 also utilizes gear oil in its transmission and differential systems. The specific type and capacity may differ slightly from the 800 model, so it is always best to consult your owner's manual for the precise specifications for your particular Outlander 400.
Frequently Asked Questions
Q1: Can I use motorcycle-specific oil in my Outlander 800 engine?
A1: While motorcycle oils are formulated for specific wet clutch systems, your Outlander 800's engine does not have these requirements. Using a high-quality full synthetic automotive oil is perfectly adequate and often more cost-effective. Ensure it meets the API specifications recommended in your owner's manual.
Q2: How often should I change my ATV's drivetrain fluids?
A2: It is generally recommended to change your drivetrain fluids every 1,000 miles or annually, whichever comes first. However, if you frequently ride in deep water or mud, more frequent changes may be beneficial to prevent moisture contamination.
Q3: What happens if I overfill the rear differential?
A3: Overfilling the rear differential can lead to increased internal pressure. This pressure can force the fluid past the seals, causing leaks and potentially leading to a loss of lubrication, which will accelerate wear on the differential components.
Q4: Is it okay to mix different brands of gear oil?
A4: It's best to avoid mixing different brands or types of gear oil, even if they have the same specifications. Different formulations may contain additives that are not compatible with each other, potentially leading to reduced performance or component damage. Always use the same type and brand of oil for each component change.
Q5: Do I need to use BRP-branded fluids?
A5: No, you do not necessarily need to use BRP-branded fluids. As long as the aftermarket fluids you choose meet or exceed the specifications (viscosity grade, API rating, etc.) recommended by BRP in your owner's manual, they will provide equivalent or even superior lubrication and protection for your ATV.
By adhering to these fluid recommendations and capacities, you can ensure that your 2009 Can-Am Outlander 800's engine and drivetrain remain in peak condition, ready for whatever the trails throw your way. Regular fluid checks and changes are a cornerstone of good ATV maintenance, contributing significantly to the longevity and reliability of your machine.
