At the manufacturer's request the engine may be tested on a third fuel instead of G23 (fuel 3) if the λ-shift factor (Sλ) lies between 0,89 (that is the lower range of GR) and 1,19 (that is the upper range of G25), for example when fuel 3 is a market fuel. The results of this test may be used as a basis for the evaluation of the conformity of the production.
