Mitsu told me (all over the phone) Transport Canada has really strange rules with OEM blended oils.
Idemitsu wanted to supply a much more robust oil, Transport Canada put a stop to it and made Mitsu deal with Petro Can.
Politics in Oil sucks. Especially when the end product could have been much better.
This what I was told by Mitsu and Idemitsu. Over the phone.
That makes absolutely no sense to me.
Honda, Acura, Subaru and Mitsubishi all use Idemitsu USA bottled oil that's imported into Canada.
You can rest assured the Petro-Canada made Mazda Canada 0W-20 is the same as PCs own 0W-20.
