What Type of Oil Does a 2021 Can-Am Outlander Max 570 Take?

The 2021 Can-Am Outlander Max 570 is a two-up utility quad built around a liquid-cooled, single-cylinder Rotax four-stroke engine, and that one fact settles the biggest question immediately. This ATV runs on four-stroke engine oil. There is no premix to measure, no injection reservoir to keep topped off, and no two-stroke oil anywhere in the machine. What follows is practical guidance on the type and weight of oil that suits this quad, the drivetrain lubricants that live alongside the engine, and the ways real work use changes what you should be pouring in.
Four-Stroke Engine Oil Is the Starting Point
The Outlander Max 570 uses a 570cc single-cylinder, liquid-cooled, overhead-cam four-stroke. It breathes through fuel injection, drives through a belt-type continuously variable transmission, and sends power to the wheels through shaft drive. Every one of those details points to the same conclusion: a dedicated four-stroke powersports engine oil is the correct choice, not an automotive oil pulled off the shelf at a general retailer.
Powersports oils are blended with the additive package that wet clutches, high-revving single-cylinder engines, and shared engine-and-gearbox sumps actually need. Automotive oils are formulated around catalytic converters and fuel economy targets, which is a different set of priorities entirely. For a work machine that spends its life at low speed under load, the right additive chemistry matters more than the label on the bottle.
Viscosity: What Weight Fits This Quad
Utility ATVs in this displacement class most commonly call for a 5W-40 or 10W-40 viscosity, and the Outlander family is no exception to that pattern. A 5W-40 flows more readily on a cold morning, which makes it a sensible pick for owners who plow snow or start their quad in freezing temperatures. A 10W-40 is the more common year-round choice in moderate climates and is what most riders will find on the shelf in a powersports-specific formulation.
Owners in consistently hot regions, or those running long, slow, heavily loaded days in summer heat, sometimes step up to a 20W-50 for extra film strength at temperature. At the other extreme, a 0W-40 can be a reasonable cold-weather option where winter starts are routinely below freezing. The first number describes cold-flow behavior and the second describes viscosity at operating temperature, so the pair you choose should reflect the conditions you actually ride in rather than a single universal answer.
Can-Am publishes its own branded oil specification for this machine, and following the manufacturer's recommendation is a sound default when you want to keep things simple. The exact figure for your specific build is printed in the owner's manual, and a quick look there removes any doubt.
How the CVT and Wet Clutch Shape Your Choice
The Outlander Max 570 uses a belt-driven CVT, which means the drive belt itself runs dry and outside the engine oil supply. That does not mean clutch friction material is absent from the oil, though. A wet centrifugal clutch lives inside the engine case on this design, and the gearbox shares the same oil supply as the engine on this platform. Because of that shared sump, the oil has to lubricate gears and manage clutch engagement at the same time.
That is exactly why a JASO MA or MA2 rated oil is the right call. Those ratings exist to certify that an oil will not cause a wet clutch to slip, and they are the standard reference point for powersports machines with shared engine and transmission lubrication. Oils marketed as energy conserving, or those carrying friction modifiers aimed at automotive fuel economy, can cause clutch chatter or slipping in this kind of setup and should be avoided.
Drivetrain Fluids Beyond the Engine
Engine oil is only part of the picture on a four-wheel-drive utility quad. The Outlander Max 570 also carries a front differential and a rear gearcase or final drive, each with its own lubricant and its own service interval. These are filled, checked, and changed separately from the engine, and mixing them up is a common and avoidable mistake.
The rear final drive typically uses a hypoid gear oil in the 75W-90 or 80W-90 range. The front differential on this machine uses a specialized fluid tied to its automatic locking engagement system, and using a generic gear oil there can affect how and when four-wheel drive engages. If your quad is a two-wheel-drive variant, the rear gearcase is the only one you need to think about. Either way, these fluids are not interchangeable with engine oil and should be confirmed against the manual before you buy.
How Hard Work Changes the Equation
Plowing, towing a trailer, hauling game, crawling through mud, and idling for long stretches while you work are all harder on oil than a casual trail ride. Slow-speed heavy loads raise oil temperature and shear the viscosity index improvers in the oil faster, which shortens its useful life. Dust and grit pulled in on dirty trails accelerate the same wear.
Water crossings deserve special attention. If water or muddy slurry gets past a vent or seal, engine oil can turn milky or frothy, and that appearance is a clear signal to change it right away rather than waiting for the next scheduled interval. Owners who regularly work their quad in these conditions should plan on shorter change intervals than the book suggests, and should check the drivetrain fluids on the same shortened schedule.
Synthetic, Semi-Synthetic, or Conventional
Full synthetic oils generally hold up better under heat, resist viscosity breakdown longer, and flow more easily on cold starts, which makes them a strong fit for a machine that works hard in temperature extremes. Semi-synthetic blends land in the middle and cover most riders well. Conventional oil costs less and remains perfectly serviceable for an owner who changes it on time and rides in moderate conditions.
Whichever you pick, the rating matters more than the base stock. A conventional oil with the correct JASO MA2 rating and the right viscosity will protect this engine better than a synthetic that lacks the wet-clutch certification.
Confirming the Exact Spec for Your Machine
Everything above reflects the common, well-documented practice for this class of utility ATV, and it will get you to the right shelf in the store. For the precise viscosity, the exact fill quantity, and the specific drivetrain fluid types your 2021 Outlander Max 570 was built to use, check the owner's manual or ask a dealer. It takes a minute, and it turns good general guidance into an exact answer for your quad.
