    Octane is one of the flammable hydrocarbons that is naturally present in gasoline. The octane rating found on the different grades of gasoline is related to the refining process: fuels with a higher octane content are more expensive to refine and cost more to store and distribute due to lower demand. Those added costs are passed on to you at the pu...

    Regular Gasoline (87 octane) Regular gasoline in Canada is typically rated at 87 octane. This is the least expensive type of fuel and is also the grade recommended for use in most engines that don’t specify a need for a higher octane rating. Mid-Grade Gasoline (89 octane) Mid-grade gasoline is typically rated at 89 octane in Canada. A few vehicles ...

    The vast majority of cars that require or recommend premium fuel will say so on a sticker inside the fuel door or on the gas cap. However, this is not a universal rule, and used vehicles may have had these stickers removed. The safest bet is to check the owner’s manual for the automaker's recommendation, where the octane level required by the engin...

    Since 2022, all fuel types and gasoline grades sold in Canada contain a certain amount of ethanol to help reduce vehicle emissions overall—though the mix of these blends can change depending on the requirements of different provinces and the products available at different gas station chains. The basic requirement, however, are the national Renewab...

    Canada halted the sale of leaded gasoline in 1990, and the vast majority of modern cars have been designed from the outset to run on unleaded gasoline. However, if you run a classic car, you may need to use additives in your petrol, although many classics have been converted so that they will happily run on unleaded gas.

  3. What’s octane, you ask? Octane determines the speed and temperature of combustion. The higher the octane number, the higher the temperature needs to reach before the gasoline burns. 87, or regular gasoline, burns the quickest and coolest. But is premium fuel worth the extra cost? It depends.

  4. When combusted, premium (high-octane) gasoline and the less-expensive (and less-glamorous) regular, and all grades in between, provide the same amount of thermal energy, or heat, which an engine uses to generate the mechanical power that moves a vehicle.

  5. Dec 7, 2022 · As premium gas helps improve fuel efficiency and offers optimal performance, it is usually recommended by the manufacturer for specific vehicles. Premium gas usually costs 20 to 30 cents more per gallon than regular gasoline, but it typically contains more octane.

  6. Nov 17, 2022 · What is octane? In recent years, car manufacturers have been requiring or recommending premium gasoline (a high-octane grade of fuel) for use in more of their vehicle models. The difference in prices between premium and lower octane grades has also increased. Octane ratings are measures of fuel stability.

  7. Dec 13, 2019 · Regular gasoline is rated at 87 octane in most states while premium is rated at 91 or 93. What does that mean? Gas with a higher octane can withstand a higher compression before detonating, meaning the higher the octane, the lower the likelihood the fuel will detonate at the wrong time.
