Double Ester Technology: Type 2193E (5W-40) is a select, synthetic multi-grade oil which mixes polyol esters for maximum oil film resistance, balanced polarity and increased stability at very high temperature.
NISMO Competition Oil 2193E 5W-40 was developed along with the VR38DETT engine, focused on high-performance motorsports use, like the Tokachi 24 Hours, used in the NISSAN GT-R NISMO RC and NISSAN GT-R Club Track Edition, and raced in the 24 Hours Nürburgring. The final result of all this testing was the choice of a 5W-40 over a 0W-40 viscosity grade.
NISMO Competition Oil 2193E 5W-40 maintains the GT-Rs top performance under high load conditions while providing the engine with the extra protection needed to meet the demands of Motorsports use.
This oil increases engine output through reduced usage of detergent-dispersants additives that cause friction losses in high-load conditions. Its unique base oils and friction modifiers provide High HTHS (High Temperature High Shear) viscosity together with a consistent oil film and excellent anti-coking performance for improved lubrication and cleanliness of turbine bearings.

NISMO COMPETITION OIL lubricants were developed for high performance and aggressive driving.
The Type 2193E (5W-40) motor oil is officially recognized as being in conformity with NISSAN warranties only when used in NISSAN GT-R (R35).
NISMO recommends changing oil every ~ 1850 miles (3,000 km) under harsh driving conditions.
NISMO recommends changing oil every ~ 6000 miles (10,000 km) of normal road use.
Do not mix with other lubricants.
