Regular E10 (87 Octane)

Our regular unleaded fuel is suitable for the majority of vehicles on the road. All of our stations feature an ethanol blend of up to 10%. Ethanol is a renewable fuel source and helps prevent your vehicle gas lines from freezing in the winter months.

Mid-Grade (89 Octane)

Our Mid-Grade fuel is a blend of Super and Regular unleaded fuels. You get an enhanced octane rating, which is beneficial if your engine knocks or pings. This fuel grade may contain up to 5% ethanol as it is a blend of Super and Regular fuels.

Super (91 Octane)

This gasoline offers drivers of luxury and performance vehicles the octane level their vehicle requires. Our Super grade is ideal for high-performance engines, turbocharged engines and high compression motors found on boats and snowmobiles.


We offer diesel fuel at over 95% of our locations. During the winter months at our Northern Ontario sites, we ensure that only winter diesel is sold, as this offers  better protection against gelling and condensation build up in your fuel tank. All of our diesel fuel formulated to meet or exceed all fuel requirements and is formulated as Ultra Low Sulfur Diesel to reduce emissions.

At select locations, our diesel may contain up to 20% biodiesel. All diesel pumps with biodiesel will be clearly labeled. Biodiesel is a diesel fuel substitute that is made from renewable materials and used to fuel on-road and off-road diesel engines without any engine modifications required. Compared to regular diesel, biodiesel reduces lifecycle greenhouse gas emissions and displaces fossil diesel. Biodiesel is a more sustainable fuel, and as a replacement diesel, it helps to fight
climate change. Our biodiesel meets CGSB Standards and passes Cold Soak Filter Blocking Tendency (CSFVT) test. Please consult your owner’s manual, as fuel may not be suitable for some engines.
