For all of the Canadians here, some may know this but I figured I would share it anyways. I was looking at this weeks Canadian Tire flyer and there it was 4L jugs of Rotella ELC coolant, I click on it and it says available in concentrate and 50/50. Showing a regular price of $24 for 4L jug. I regularly look at their automotive section and this would be the first time I have seen it.
Personally I am going to hit up my local bulk dealer and see if I can get a better price. It is still nice to know I don't have to go far to get a jug in a pinch
