Premium gasoline is rated between 91 and 93 octane, while regular is rated at 87 octane. The octane rating is the resistance of the gasoline to igniting, and higher compression engines need higher octane rating to prevent pre-detonation or pinging. Check your owner's manual to see if you need premium or can run the less expensive regular.
No, premium is unleaded gas as well and the difference in octane ratings between regular (87) and premium (91) is is not going to cause an engine to seize. Running the gas/oil ratio to lean will though.
What color is premium gas
Premium is required
I used regular gas in my 2009 Murano. Ocassionally, I use the premium when I have extra cash.
you can use regular or premium
higher OCTANE!
i am guessing you should use premium gas for a Chrysler 300. Regular is ok unless you have a SRT8.
Premium unleaded is recommended, but I'm running 92 octane std unleaded at the moment, hasn't made any difference. Pete
Yes, I have a 2004 Acura TSX with 45,000 miles on it. I used regular gas when it was $4.00 a gallon and I got worse MPG by about 3.5 and the engine was "spark Knocking". Hope this helps.
Use what the manual tells you....regular gas.
Premium is a "pump gas". "Pump gas" is term used for any grade gas found at any given gas station such as regular, mid grade, and premium. It doesn't burn faster it gives a more complete burn which eliminates a significant amount of the carbon which you get when you burn a lower grade gas. I must disagree with my learned expert. Premium does not burn faster nor does it give a cleaner burn. In fact it burns slower. The only difference in Premium and Regular is the octane level. A higher octane provides no benefit whatsoever in an engine designed to run on regular. No more power, no better mileage, nothing. In fact if used in an engine designed to run Regular you may suffer harder starting.
