Modern ROTAX® 9‑series engines ask a lot from their oil: quick cold starts, clean operation on unleaded and AVGAS, stable viscosity under turbocharged heat loads, plus dependable lubrication for the integrated prop gearbox and overload clutch. XPS Full Synthetic 5W‑50 was built expressly for those demands.
Formulated specifically for ROTAX Aircraft Engines
XPS Aviation Engine Oil was formulated specifically for ROTAX aircraft engines and validated through extensive development and fired‑engine testing.
The goal: predictable protection, consistent pressures, and clean operation across the envelope.
Designed for use with MOGAS & AVGAS
Rotax engines have been designed to operate on both MOGAS & AVGAS fuels that have specific requirements for an oil. That’s when detergent performance and disciplined maintenance make a difference. XPS is formulated for the realities of mixed‑fuel operations, supporting clean ring packs and internal surfaces. If your operation includes sustained AVGAS use, follow the shortened oil‑change intervals and lead‑management practices in your SI and maintenance manual.
Designed with the ROTAX gearbox and clutch in mind
ROTAX’s integrated prop gearbox and overload clutch need the right friction characteristics. XPS’s additive system is engineered to protect gears and bearings while guarding against excessive clutch slip—exactly the balance these engines demand.
Compliance corner: get the most from your oil (and your engine)
- Check the current SI for your engine type (916 i, 915 i, 912 i, 912, 914) and follow the listed oils and intervals. Refer to flyrotax.com
- Match your interval to your fuel: more frequent oil changes when using AVGAS; follow any gearbox inspection requirements related to lead exposure.
Bottom line
If you fly behind a ROTAX engine, XPS brings exactly the attributes the platform demands: cold‑start agility, hot‑side stability for turbocharged power, detergency for unleaded and AVGAS realities, and friction tuning for the ROTAX gearbox and clutch. Pair it with the current SI and a disciplined maintenance routine, and you’ve made a smart, pilot‑first choice.
