Scope
This specification covers a neopentyl polyol ester fluid (see 8.2) with AS5780 HPC or MIL-PRF-23699 HTS Class performance.
Rationale
Turbine oil base-stocks formulated for high thermal and oxidative stability tend to be more aggressive toward some fluorocarbon elastomer compounds used in aerospace applications. Reference Oil 300 provides a reference fluid that more closely simulates the performance of today's high-performance classification turbine oils described in AS5780. This revision broadens the viscosity limits in Table 1 to be consistent with AS5780 viscosity limits and allow necessary manufacturing margin for this property.

* Redlines comparisons are available for those standards
listed in the Revision History that contain a radio button. A
redline comparison of the current version against a revision is
accomplished by selecting the radio button next to the standard and
then selecting 'compare'. At this time, Redline versions only exist
for some AMS standards. SAE will continue to add redline versioning
with ongoing updates to SAE MOBILUS.
