Fuel Quality

Fuels are constantly improving thanks to research and innovation. Some of the improvements in recent years include: 

• Higher octane ratings
• Improved stability to help reduce the formation of impurities in the fuel
• Improved distillation characteristics, for smoother driving and steady acceleration
• Modified formulations to reduce the smog forming potential and toxicity of unburned fuel
• Reduced sulphur levels and the elimination of lead to increase the effectiveness of vehicle emissions control systems
• Reduced volatility to reduce evaporative emissions from vehicles
• Deposit control additives to minimize emissions from engines due to deposit formation in the intake manifold, on engine valves, or in combustion chambers.

Does more need to be done? Absolutely. Canada’s refineries are committed to continuous improvement so that today’s transportation fuels are cleaner tomorrow.
