That's a good question. Finding Red Line at that price in Canada might be a bit of a stretch; with Amsoil, it wouldn't be so hard. If Canadian Tire thought they could sell Red Line at $11 to $12 per litre and make what they considered an effective profit out of it, they'd be doing so. They cleared out Red Line ages ago. I'm surprised Canadian Tire has hung onto Royal Purple this long.
Canadian Tire and Walmart, along with a few other bigger box stores here, are under the mistaken belief that oil needs to be marked up by 150% to 200%, and then slashed to create a colourful sale every few weeks, when a jobber outlet tries to keep the markup on the same product under 20%.
