aroa,
Green Band is still around.
The problem with some of the excellent modern oils is that individuals in CASA demand that the original manufacturers recommendations be observed, precluding the use of modern oils.
Modern multi-grade oils are way ahead, even in old engines, but my experiences in getting approval to use modern oils that are sold as direct replacements for older single grade oils was, to say the least, disheartening.
In total contrast, of course, to FAA or NZ CAA.
What I would never admit to, in public, of course, would be to the use of some excellent oil additives, specifically developed by the USAF in the '50s, for big radials, which are just as applicable to small piston engines.
Tootle pip!!
