Yes, it certainly is. However, you can't rule that one cannot compare to other grades or to what it "isn't." It'll win as a fuel economy oil versus a 15w-40. It'll fail in comparison to a 10w-30 or a 5w-30 HDEO. In any case, for me, a three season oil isn't really an option I'll be choosing.
As for Petro-Canada, I'm not seeing any E6 10w-40. Am I missing something? Their ACEA coverage is a little spotty and they're using expired sequences, too, except for their 5w-30 UHP.
Most E6 examples I've seen worldwide have been 5w-30, contrary to what the ACEA verbiage states. I've seen Castrol, Mobil, Chevron, and now Petro-Canada variants, and they've all been 5w-30. Now I'm curious as to the cost and jug size from Petro-Canada for that product.
