In case anyone in Canada was interested, while our Walmart's don't stock this Supertech Semi-Synth 75w90 gear oil (we get stuck with castrol at $20/l), Canadian Tire has Motomaster brand Semi-Synth (GL-5, MT-1, Milspec, etc...) in 1L and 4L containers. $9 per 1L, or $33 per 4L, which is a much better deal than anything else readily availible here.
I have irritated many a Walmart employee looking for this stuff in Quebec and Eastern Ontario, and have settled on the Motomaster stuff. On NASIOC there are some good reviews, and the Forester forums has a few kudos for this stuff too.
