Boost and Workload Both Cash Out as Heat
The Maverick X3's turbocharged Rotax makes big power from small displacement — which means high cylinder pressures, high oil temperatures, and a turbo whose bearings live on the engine oil. The Defender's V-twin faces the opposite profile: moderate RPM but relentless load — plowing, towing, hauling feed — often at low ground speed with minimal cooling airflow. Different machines, same enemy: friction-generated heat accelerating wear in a small engine asked to do big work.
A ceramic surface treatment attacks that at the origin. The SiC layer reduces metal-on-metal friction, which lowers heat generation, which slows oil breakdown — a chain that matters most in exactly these two duty cycles. (Chemistry deep-dive: What Is Nano Silicon Carbide?)
Model by Model
| Machine | Typical duty | What Cerma addresses |
|---|---|---|
| Defender (HD7 / HD9 / HD10) | Work machine — towing, hauling, ranch and property duty | Sustained-load heat and wear at low airflow; quieter, cooler running under load |
| Maverick X3 (Turbo / Turbo RR) | Performance — dunes, desert, sustained boost | Friction heat at high sustained RPM; oil-temp reduction benefits the turbo's oil-fed bearings |
| Commander / Outlander | Mixed trail and work duty | Same Rotax fundamentals — one treatment covers the engine's working life |

How to Apply Cerma STM-3 to Your Can-Am
- Start with fresh oil and filter — begin a normal service so the treatment travels in clean oil.
- Add STM-3 to the crankcase per the bottle's small-engine dosing.
- Ride normally — the SiC bonds into the friction surfaces over the treatment cycle; boost and load are fine.
- Resume normal oil changes — the ceramic layer stays put; it does not drain out.

Complete the System: Oil, Gearcases, Fuel
- Oil: CERMAX 4-Cycle ceramic synthetic — our powersports oil, ceramic-fortified for hours-based hard use and turbo heat.
- Transmission/gearcases: Cerma gear treatments carry the friction reduction into the gearbox and diffs.
- Fuel side: ethanol pump gas and seasonal use hit UTV fuel systems hard — the Cerma fuel treatment cleans injectors and removes water at 1oz per 40 gallons.
Frequently Asked Questions
Is Cerma safe for the X3's turbo?
Yes — turbo bearings are oil-fed friction surfaces, which is exactly what the treatment conditions. Lower friction heat in the engine also means the oil reaching the turbo runs cooler and degrades slower. (Note: Cerma also makes a dedicated Turbo treatment — the engine must be treated first; ask us about sequencing.)
Will it affect the CVT belt or clutches?
No. Can-Am's CVT is belt-driven and separate from the engine oil circuit — the treatment never contacts belt or clutch surfaces.
How long does one application last on an hours-metered machine?
The protection window — up to 125,000 miles in automotive terms — is effectively the working life of a typical UTV. Paired with Cermax ceramic oil, it's a true lifetime treatment.
Will it void my BRP warranty?
Under the Magnuson-Moss Warranty Act, a manufacturer must show a product actually caused a failure to deny a warranty claim. See our full guide: "Does Engine Treatment Void Your Car Warranty?"
My Defender mostly idles and crawls. Does it still benefit?
Arguably more than anything: low ground speed means low cooling airflow while the engine works hard. Reducing friction heat at the source is most valuable exactly when airflow can't carry the heat away.
