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.

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.
