Hi Eberjer078,
I've contacted Halton Honda who are also now getting the 0W-20 in bulk. Apparently the oil is sourced differently than that in the bottles and drums. And yes they claim it is from Petro-Canada.
I have sent off an email request to Honda Canada on the source of the bulk oil. If it does turn out to be the PC 0W-20 rest assured it's a fine oil but nothing special. It is heavier than the Idemitsu oil on start-up due to it's much lower 168 viscosity index and it doesn't contain the same AW package, primarily the high moly levels.
Since the Idemitsu made oil in bottles is such a good deal at around $5/L on a 12L case, given the choice that's the oil I would request if Honda was doing the OC for you.
