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

If you own a 2021 Can-Am Renegade 570, the short answer is that it takes a four-stroke powersports engine oil, most commonly in a 10W-40 or 5W-40 viscosity, and it does not use two-stroke premix or injection oil of any kind. The longer answer is worth reading, because the Renegade 570 is a specific kind of machine — a liquid-cooled single-cylinder four-stroke with a belt-driven CVT and selectable 4x4 — and that combination shapes which oil is right, how much of it the engine holds, and what other fluids on the quad need attention.
Four-Stroke, Not Two-Stroke: What That Means at the Parts Counter
The Renegade 570 is powered by a 570cc liquid-cooled four-stroke single. There is no oil-injection reservoir to top off and no fuel-to-oil ratio to measure at the pump. All of the engine's lubrication lives in the crankcase, gets circulated by an oil pump, passes through a filter, and is drained and replaced at service time. That single fact eliminates an entire category of products from your shopping list.
What it does not eliminate is the need for the right kind of four-stroke oil. A quad engine is not a car engine. It runs at higher sustained rpm, it is often air-starved in slow technical terrain, and it shares its oil with components that automotive oils are not formulated to handle. Powersports-specific four-stroke oil is the correct category, and it is widely available in both conventional and synthetic form.
Viscosity: The Weight That Fits a 570-Class Quad
Across the 500cc to 600cc four-stroke ATV class, 10W-40 is the most commonly cited viscosity, with 5W-40 appearing frequently as an approved alternative. Both are multigrade oils, and the first number describes cold-weather behavior while the second describes how the oil holds up once the engine is at operating temperature.
Some owner's manuals in this class also list a wider spread of options depending on ambient temperature:
- 0W-40 or 5W-40 for cold-weather starting and winter plowing
- 10W-40 as the general-purpose, all-season choice
- 20W-50 for hot climates or sustained heavy-load work in high heat
If you ride in a region with genuine seasonal swings, the lower first number is the one that matters most on a cold morning, because it determines how quickly oil reaches the top end at startup. The exact viscosity your machine was built around is printed in the owner's manual, and confirming it takes about thirty seconds.
Why the CVT Changes the Oil Conversation
The Renegade 570 uses a belt-driven continuously variable transmission. The belt itself runs dry, outside the engine oil, which means the engine oil is not being asked to satisfy wet-clutch friction requirements the way it would be on a quad with a geared gearbox and a clutch bathed in the same sump. That is a meaningful distinction, and it is why you will sometimes see CVT-equipped machines described as more forgiving about oil choice than their geared counterparts.
Forgiving is not the same as indifferent, though. The engine still has a centrifugal clutch element and still relies on its oil for camshaft, bearing, and cylinder-wall protection under load. A JASO MA or MA2 rated powersports oil is a sound, widely available default, and if Can-Am publishes its own branded formulation for this model, following that recommendation is the simplest way to stay within spec.
Drivetrain Fluids Are a Separate Job Entirely
Engine oil is only one of several lubricants on a 4x4 quad, and mixing them up is a common and avoidable mistake. The Renegade 570's four-wheel-drive system typically involves a front differential, a rear gearcase or final drive, and in some configurations a separate transmission gearcase. Each of these is filled, checked, and drained independently of the engine.
Most of these units call for a hypoid gear oil in the 80W-90 range. The front differential deserves particular attention on a machine with an engagement system, because using a fluid that is not compatible with that system can affect how and whether four-wheel drive engages. These fluids also have their own service intervals, which are usually longer than engine oil intervals but are not infinite.
How You Actually Ride Determines How Hard the Oil Works
Two owners of identical machines can have very different oil lives. Plowing driveways, towing a trailer, crawling through deep mud, crossing water, and idling for long stretches while winching all put more heat, more fuel dilution, and more contamination into the crankcase than a casual trail ride does.
Water and mud intrusion is worth watching for specifically. If the oil on the dipstick looks milky or frothy rather than amber or dark brown, moisture has found its way in, and that is a sign to change the oil rather than top it off. Cold-weather operation is the other major factor, and it is the single best argument for choosing the lower cold-viscosity number available for your machine.
Conventional or Synthetic?
Synthetic four-stroke powersports oil generally flows better at low temperatures, resists thermal breakdown more effectively during sustained hard work, and holds its viscosity longer between changes. Conventional oil costs less, is perfectly serviceable for many riders, and remains a reasonable choice for a machine that sees moderate use and regular changes.
For a quad that plows, tows, or spends its summers in mud, the case for synthetic is stronger, simply because the oil is being asked to do more. Either way, the rating and viscosity matter more than the base stock.
Intervals and Confirming the Exact Spec
Severe service — heavy loads, dust, mud, frequent short trips — generally calls for shorter oil change intervals than the standard schedule. If your riding falls into that category, treat the manual's normal interval as a ceiling rather than a target.
For the precise viscosity, the exact fill quantity, and the specific drivetrain fluid types for your 2021 Renegade 570, your owner's manual is the authoritative source, and a Can-Am dealer can confirm anything the manual leaves ambiguous. That is a quick check, not a reason to guess — and once you have the numbers, the rest of the job is straightforward.
