What is premium gasoline?

When you pull up to the gas station and look at the pumps, after the price of fuel, the various grades are you likely notice most quickly. Without getting too deep into jargon, a fuel’s octane rating determines how stable the fuel is. Generally speaking, the more octane a fuel contains, the harder it actually is to make it combust. In certain engines, this is necessary to produce high power output figures. However, if your vehicle’s owner’s manual says that premium gas is “recommended” and not “required” you will be able to use the cheaper grade gas and save yourself some money with each fill-up.

Some Mazda models do have engines that can benefit from using premium gas. The 2019 Mazda CX-9 is powered by a turbocharged engine that can get a boost of about 25 horsepower when using higher-octane fuel.

The most important thing to remember when putting gas in your vehicle is that it comes from a reputable source. Modern fuels are formulated with detergents and other chemicals to help engines run as efficiently and cleanly as possible. If you make a mistake and put premium gas in your tank and regular is recommended, don’t worry about it. Just pay more attention next time.

Is your current vehicle becoming more of a gas-guzzler? It might be time to look for something a bit new and more efficient. Make an appointment to speak with a Gwatney Mazda of Germantown product expert today to see what we have available.

    C. X 5 turning reserve can I get performance with premium fuel on road trips or just use the same all of the time

    I am getting 19.6 MPG either around town or on the open road. I have taken my 2019 CX9 to the dealership twice and the suggestion was to use a different gas station, that has a different mixture of ethanol. I was complaining about the gas mileage, and the fact that I had to fill up more often. So the solution the technitian suggested was to spend more money on different gas to get better gas mileage. A non-answer. My question has anyone else had this problem with the MPG in their new CX9???

    I put Premium in my 2018 CX5 every so often I only do this when I notice the car hesitates when stepping on the gas. I put 5 gallons of premium every 6 months and have had no more hesitations.

    CX9 2012
    Last few days on starting it is missing badly and some noice comes from the bonnet as if some valve is struggling to cope.
    Have been using 91 gas.Scanning says fuel sensor.
    The problem disappears after running it for 1/2 hour.
    Should I go for high octane?
