In Australia, Mobil 1 has always been around, but relatively more expensive and sometimes not so easy to find. This has changed recently, I'm seeing a lot more M1 in the shops and a much greater diversity of M1 products. They have just recently started offering real sale prices too. I picked some up at half price last week, the first time ever at an affordable price. It was the regular M1 5W-30, called "Newer Vehicle Formula" here in Oz. Now according to the Australian web page this Oz M1 5W30 is rated ACEA A1/B1, as well as the usual API SN, ILSAC GF-5, Honda HTO-06 and GM dexos1. Now, from the USA web page the regular M1 5W-30 is not rated A1/B1. The local Australian bottle of M1 5W30 is also clearly labeled A1/B1 on the back. Do you think it's a different formulation or slack labeling ? BTW in Oz we still have the older M1 0W40 oil with the higher HTHS and the BMW LL-01 spec.
