Have noticed in the last year or so that the source of Redline motor oil for my 70 351C is no more! Several Canadian Tire outlets within 2 hours of my location aren't carrying it...Newmarket being the furthest away that I've checked. They still have the water wetter and diesel fuel treatment but no oil. Are there CTC stores in Toronto still selling it or any other Ontario retailers at a reasonable price for 10/30, or do I need to switch to another brand?
