FAQs

What is UltraMax?

UltraMax is an enhanced fuel additive package, commonly referred to as fuel detergent. It is a sophisticated formulation of fuel detergents only available at Ultramar locations and is available in all our gasoline grades (except diesel fuel).

Are gasoline detergents necessary?

Yes, the Canadian government mandates that all gasoline sold in Canada must include a deposit control additive as outlined by the Canadian General Standards Board. UltraMax gasoline contains over two times the minimum quantity of fuel detergent required by government standards.

What octane rating is right for your engine?

Check your Original Equipment Manufacturer’s manual to see what octane rating is right for your vehicle. It’s always best to use the fuel grade recommended in your owner’s manual. Using gasoline with an octane level lower than recommended may cause knocking to occur.

Why is the cleanliness of your car’s fuel system important?

A clean fuel system supports your vehicle’s life and helps in its operation at factory-designated performance and fuel-economy specifications.

Where can I purchase UltraMax additized gasoline?

UltraMax additized gasoline is only available at Ultramar stations.**

Do we add ethanol to our Ultramar gasoline?

We follow Canada's Clean Fuel Standards (Federal and Provincial regulations) and are pleased to offer our customers lower-carbon fuel options where available. Ultramar gasolines may contain up to 10% ethanol.
