1 Liter, NISMO 75w140 Competition Oil (type 2189E) delivers the same dynamic viscosity as a 190 grade oil while providing a base grade of 75W. It is an ester compound, 100% synthetic oil with outstanding low temperature properties. An oil with a viscosity (or hyper-viscosity) of 190 has greater resistance to stirring and this raises oil temperature. But at the same time without hyper viscosity, the maintaining of film strength at high temperatures is impossible. The basic development concept for type 2189E (75w140) competition oil was to keep the benefits of hyper-viscosity while seeking to diminish resistance to stirring.
