Hey guys. Very interesting thread, thanks for sharing. I've just been trawling various oil manufacturers websites for "Jaso MA" and cross referencing the price.

Nulon carries two jaso MA oils, a 10w-40 and a 15w-40. Supershit lists them at $39.99 for a 5 litre bottle. Data sheet here: https://www.nulon.com.au/images/file...B-SEM10W40.pdf
