10w-30 ILSAC varieties, 10w-40, and 20w-50, Merk.
Actually, as you might have seen me post before, at least some Canadian Tire stores have eliminated most 10w30 ILSAC synthetics, since they are essentially obsolete. And, they've stuck to that policy.
I've got a couple of 10W30s in my shed (A3/B4, surprise surprise). Agree that an ILSAC 10W30 makes no sense, I'm surprised how long ILSAC supported it.
Pretty well agree with the 10W40, it's my least favourite of any grade.
I reckon in Oz, getting rid of 20W50 wouldn't work...it's in too many manuals, and fairly recent ones.
I'd like to see the mineral 25W and 30-70s (and the 40-70s) gone, and those people that convince people that they need them.
