The Amsoil 0w-30/5w-30/10w-30 are all now ACEA A3/B3/B4 rated, for high performance gas/diesel engines. The new spec sheets aren't on the website yet, but the quart and gallon bottles have had the new specifications on them for the past two months. These formulations also meet factory fill requirements of BMW/Mercedes 229.3/Porsche, and VW 502/505.
The only Amsoil gas engine formulations not meeting these specs are the XL-7500 series oils. These are formulated about like Mobil 1 in terms of high temp viscosity, and are SL/CF and ACEA, A1/B1 rated products.
