“The gasoline sold at any gas station in Canada almost always comes from one of a few well-known refiners,” says petroleum industry analyst Michael J. Ervin. “The only difference is that the gas for the national brand gets a proprietary detergent package added at the terminal.”
Ervin says it's generally believed that the additives are good for your engine, but he hasn't seen any studies that prove that one company's additives are better than another over the life of your vehicle.
