Most CFMOTO ATVs, UTVs, and motorcycles run on a JASO MA/MA2-rated oil in the SAE 10W-40 range, and the CFMOTO CRAFTED 10W-40 synthetic blend is the factory default for a reason. Cold climates or certain motorcycle models sometimes call for 0W-40 or 5W-40 instead. Before you buy a single quart, confirm the exact viscosity and API/JASO spec listed in your owner’s manual or technical service manual. That five-minute check saves you from a clutch problem down the road.
TL;DR:
- Using the correct viscosity, such as 10W-40 for most conditions, is essential to prevent clutch slip or premature wear on CFMOTO engines.
- Always verify oil specifications in the owner’s manual or OEM parts catalog, especially regarding API ratings and wet-clutch compatibility, before purchasing oil.
- Synthetic oils, especially those rated JASO MA2, resist heat better and are recommended for high-performance engines and heavy use in all seasons.
- The official CFMOTO oil kits include 10W-40 synthetic blend oil, a filter, and gaskets, simplifying maintenance and ensuring OEM compatibility.
- Mixing oil chemistries or using non-OEM oils that lack JASO MA/MA2 ratings increases the risk of clutch problems and engine damage.

Finding Your CFMOTO Oil Type by Model
Skipping the manual and guessing at a “close enough” oil is how owners end up with clutch slip or premature wear. CFMOTO models span everything from small-bore off-road machines to full-size UTVs, and the spec sheet changes across the CFORCE, ZFORCE, and UFORCE lines, plus the CF500, CF600, CF800, and CF1000 engine families.
Three sources settle the question every time: your owner’s manual, the technical service manual for your exact model year, and the OEM parts pages on the CFMOTO CRAFTED product catalog. If you bought through a dealer, the parts department can pull the spec in under a minute using your VIN. These questions are often answered by the maintenance section of the manual that came with the machine, or in the CFMOTO technical service manual excerpt for your platform.
Run through this before you buy oil:
- Confirm your exact model and year, since specs shift even within the same model line across production years.
- Check the specified API service rating and JASO viscosity classification listed for your engine.
- Pick the viscosity grade that matches your typical riding temperature, not just the season on the calendar.
- Confirm wet-clutch compatibility if your machine uses a wet clutch, which most CFMOTO ATVs and UTVs do.
Why Oil Grade and Viscosity Actually Matter
The two numbers in “10W-40” describe two different jobs. The “10W” rating governs how the oil flows on a cold start, when most engine wear happens because oil hasn’t reached every bearing surface yet. The “40” describes viscosity at full operating temperature, when the engine needs a thicker film to keep metal surfaces apart under load.
Full synthetic oils resist thermal breakdown better and hold their viscosity longer under heat and high RPM, which is why they’ve become the default choice for modern, higher-compression CFMOTO engines. Synthetic blends split the difference on cost while still offering better flow and deposit control than straight mineral oil. JASO MA and MA2 ratings matter specifically because they test for friction characteristics in wet clutches. An automotive oil with friction modifiers designed to improve fuel economy can cause clutch slip or chatter in a machine that shares oil between the engine and transmission, which describes most CFMOTO ATVs and UTVs.
The Factory Oils and Kits CFMOTO Actually Sells
CFMOTO’s own parts catalog keeps the decision simple if you’d rather not cross-reference specs yourself. The CFMOTO CRAFTED 10W-40 Synthetic Blend (CF-852021-00810) is formulated for CFMOTO engines and states API SL and JASO MA2 compatibility, including wet-clutch compatibility, sold in quart bottles.
For a full service in one purchase, the CFMOTO Oil Change Kit (CF-852021-00816) bundles 3 quarts of 10W-40 off-road oil with a filter and gaskets, sized for many CFORCE, ZFORCE, and UFORCE models. It’s the fastest way to grab everything a service requires without hunting down individual parts.
- CFMOTO CRAFTED 10W-40 Synthetic Blend: single-quart, API SL and JASO MA2 rated, wet-clutch safe.
- 10W-40 Off-Road 3-Quart Kit: oil, filter, and gaskets bundled for a complete change.
Some manuals list 0W-40 or 5W-40 as approved alternatives, usually for colder climates or specific motorcycle platforms. If OEM oil isn’t in stock locally, any aftermarket oil that explicitly meets the same API and JASO specs is an acceptable substitute.
Pro Tip: Don’t judge oil compatibility by bottle color or brand reputation alone. Read the API service letters and JASO rating printed on the label, the same way you’d check a coolant label instead of trusting the color of the fluid.
A Decision Checklist for Your Riding Conditions
Picking the right oil isn’t complicated once you work through it in order rather than guessing at a viscosity that “sounds right.”
- Pull your owner’s manual or technical service manual and confirm the exact spec and oil capacity for your model.
- Verify the required API rating and JASO classification, prioritizing JASO MA or MA2 if your machine has a wet clutch.
- Match viscosity to your climate and use: 0W-40 for hard cold starts, 10W-40 as the all-season default, and 15W-40 only where the manual allows it for hot climates or older engines.
- Weigh synthetic against synthetic blend based on your riding style. Full synthetic earns its higher price for high-RPM trail riding and heavy hauling.
One risk gets overlooked constantly: mixing oil chemistries. If you’re not sure what’s currently in the engine because of a previous owner or an unknown top-off, a complete oil and filter change to an OEM-recommended oil is the safer move rather than guessing at compatibility between unknown additive packages.
Oil Change Basics: Capacity, Filters, and Intervals
Warm the engine for a few minutes before draining. Cold oil carries more sludge and contaminants in suspension, so draining it warm pulls more debris out with it. Replace the oil filter at every oil change, not every other one. A cheap filter is the wrong place to save money on a machine you’re trusting your knees and knuckles to.
Torque the drain plug to the exact model-specific value rather than “snug plus a quarter turn.” Overtightening strips the pan threads, and CFMOTO’s torque specs vary by model, so check the number before you reach for a wrench. Capacities and intervals also shift by model. Many CFORCE and ZFORCE machines take somewhere in the 2 to 3 quart range, but your maintenance schedule has the exact figure for your engine.
- Drain warm, never cold.
- Replace the filter every single service, no exceptions.
- Torque the drain plug to spec, not by feel.
- Refill to the dipstick or sight glass line, then recheck after a short warmup run.
- Dispose of used oil at a certified collection site rather than pouring it out or tossing it with household trash.
Pro Tip: If you’re not confident torquing a drain plug on a machine still under warranty, that’s exactly what a dealer service bay is for. Stripped threads are an expensive mistake to fix.
What Years of Selling and Servicing CFMOTOs Taught Us
Owners ask us constantly whether a cheaper automotive oil will work “just this once.” It technically pours into the crankcase fine. Whether it protects the clutch the way a JASO-rated oil does is a different question, and it’s not one worth gambling on with a machine you rely on. Every technician we’ve worked with treats wet-clutch compatibility as non-negotiable, not a nice-to-have footnote on the bottle.
Experience across many customers shows that riders who stick with OEM CFMOTO CRAFTED oil or a verified API/JASO equivalent report fewer clutch complaints and cleaner service intervals. That’s not a marketing claim, it’s what shows up on the service bench.

Get the Right Oil Without the Guesswork
The OEM oil and change kits CFMOTO engineers for these machines are available to help avoid cross-referencing part numbers or hoping a generic aftermarket bottle meets spec. Service bays may also be available for performing oil changes.
If you’re ready to service your machine, order the 10W-40 off-road oil change kit through our parts department or book a service appointment directly with Dirty Birdy Powersports. While you’re prepping your machine for the season, it’s also worth checking your tires. Our Braven Bloodaxe R/T Hybrid radials are a common upgrade for owners already in for maintenance. Riders who log a lot of trail time also ask us about the Gnet MVR G1 Pro dashcam for documenting rides. Reach out to schedule your next oil change or place a parts order today.
