Superior Stability

The comparison of HyJet IV-Aplus with competitive oils is based on side-by-side testing of samples. It demonstrates the superiority of HyJet IV-Aplus at a range of temperatures.

The fluid life for HyJet IV-Aplus as a function of temperature in
these test conditions is about twice that of the next best commercial Type IV fluid. Experience with fluid samples from
hydraulic system from severe aircraft collaborates the superior
performance of HyJet IV-Aplus observed in these laboratory
experiments.
