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 15w40. It'll fail in comparison to a 10w30 or a 5w30 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 5w30 UHP.
Most E6 examples I've seen worldwide have been 5w30, contrary to what the ACEA verbiage states. I've seen Castrol, Mobil, Chevron, and now Petro-Canada variants, and they've all been 5w30. Now I'm curious as to the cost and jug size from Petro-Canada for that product.
