It's based on the same foundation as the 10W-30: 100% synthetic, loaded with molybdenum, and designed to seal better, minimise wear and burn as cleanly as possible. The result? Less carbon build-up, better compression and real protection, especially when hitting the rev limiter.
This oil is made for those who use their rotary as it was meant to be used—even if it's got some years behind it. Whether it's trackdays or twisty backroads, where others give in to heat or stress, this one holds strong.
🔍Why choose it?
💥 High viscosity = extra shield for high-stress engines.
🔥 Burns clean and keeps carbon build-up to a minimum.
🧩 Protects bearings, turbos and gears at high RPMs.
🛡️ Tough oil film even in hot weather or tuned setups.
📆When to change it?
We recommend changing the oil every 10,000 km in regular use, and cutting that to 5,000 km if you run track sessions or spirited mountain driving.
In a rotary, oil is everything—better early than too late.
Don't forget to pair it with IDEMITSU PREMIX to maximise your engine's protection and lubrication.
