People in Kalispell MT often ask the question: "Will using premium gas make my car run better?" The answer is simple. But first, let's talk about what exactly premium gasoline is.
Different grades of gasoline have different octane ratings. Regular gasoline has the lowest octane rating and premium the highest. Most gas stations around Kalispell MT also carry a mid-grade that falls in between the two. The octane range for the different grades of gas varies by region due to altitude differences.
Engines require different octane ratings because of design differences. For example, turbocharged engines usually require premium gas.
There's a sticker on your gas tank filler lid that tells you the minimum octane rating your manufacturer recommends.

You’ll lose some performance, but won't do damage. With other engines, using a lower grade of fuel could result in serious damage; so you don't want to save a couple of bucks at the pump only to pay it out a hundred fold at the repair shop.
