Understanding Idemitsu ATF vs CVT Fluids
Automatic transmission fluid (ATF) and CVT fluid are not interchangeable. Idemitsu produces separate formulations for each type due to fundamental design differences.
Automatic Transmission Fluids (ATF)
- Designed for planetary gearsets
- Require precise friction modifiers for clutch packs
- Support the torque converter operation
- Used in 5- to 10-speed automatics
Continuously Variable Transmission Fluids (CVTF)
- Designed for belt or chain-driven pulleys
- Must prevent belt slip under extreme pressure
- Provide high shear stability
- Used in CVT-equipped vehicles only
Using ATF in a CVT (or vice versa) can cause severe transmission damage.

Is Idemitsu the Same as OEM Transmission Fluid?
In many cases, yes. Idemitsu is a factory supplier for several automakers, meaning:
- Honda factory-fill ATF is manufactured by Idemitsu
- Many Toyota and Mazda fluids are produced by Idemitsu
- Nissan and Subaru CVT fluids are closely matched
While OEM bottles may carry a different label, the formulation and performance characteristics are often the same or extremely similar.
When Should You Change Idemitsu Transmission Fluid?
Recommended service intervals vary by vehicle and driving conditions, but general guidelines include:
- Automatic transmissions: Every 40,000–60,000 miles
- CVT transmissions: Every 30,000–50,000 miles
- Severe use (towing, heat, stop-and-go driving): Shorter intervals
Always follow the manufacturer’s service schedule when available.

Can You Mix Idemitsu Transmission Fluids?
Mixing different Idemitsu fluids is not recommended unless the fluids share the exact same OEM specification. Even small differences in friction properties can affect shift quality and long-term reliability.
If topping off:
- Use the same Idemitsu fluid already in the transmission
- Avoid mixing ATF and CVTF under any circumstances
Final Thoughts
Idemitsu transmission fluids are among the most trusted and technically advanced lubricants available today, especially for Japanese vehicles. Because of their OEM heritage, they offer factory-level protection, smooth operation, and long service life when used correctly.
By referencing the Idemitsu Transmission Fluid Chart, you can confidently choose the correct fluid for your vehicle, avoid costly transmission damage, and maintain optimal performance for years to come.
