Check your user's manual. Many people mistakenly use "premium gas" because they think it is better in some way. The labels "regular" and "premium" have to do with the anti-knock characteristics of the fuel.
Big boom-boom.
NO.. it does not need premium gas.. You only have to put premium gas in a car which recommends premium gas. I would recommend a fill up with some mid grade gas atleast once a month...
Well if you think about it, why would it say to ONLY use premium...because it only uses premium for gas. My dad teaches me about cars and stuff, so...dont put mid grade gas on your car. Follow what it said and you will be fine.
That car is designed to use the regular leaded gasoline not the premium gas.
Bad idea. Most cars that are Premium Only are designed to take about 92 octane fuel at the lowest. The car will, in fact, run with super unleaded gas but it will create damage to your engine in the long-run. And if low octane gas is used frequently, it can greatly reduce the life of your car.
I have the same car and I recently discovered Premium Unleaded gas is what I am supposed to use. It says it on the inside of the flap where you put the gas in.
Unless you are drag racing your car nothing will happen to it at all. With modern cars the computer will adjust for the lower grade gas by retarding the ignition timing. If you are really driving the car hard and are on a low grade of gas you may get pre-ignition of the fuel or 'spark knock' which over the long term can be harmful but if it only happens when passing or for a short time say up a hill is not a problem. If the car calls for premium fuel however you should use it most of the time. It will cost a bit more at the pump but your engine will run cleaner and get better mileage. However, if your car does not call for premium then filling it with the 'good stuff' is a waste of money.
The Kia Sedona requires 87 or higher octane fuel. In the US, "regular" gas is 87 octane, middle grade is 89, and premium is 91-92. For this car, you only need regular grade gas. You *can* use premium, but it is not at all necessary.
Premium is required
If you value your car I would recommend it, it WILL run better that way.
Premium gas
I used regular gas in my 2009 Murano. Ocassionally, I use the premium when I have extra cash.
