Centennial area auto owners often ask the question: “Will using premium gas make my car run better?” The answer is simple. But first, let’s talk about premium gasoline; what is it, exactly?
Different grades of gasoline have different octane ratings. Regular gasoline has the lowest octane rating and premium the highest. Most gas stations around Denver, Colorado 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 automobile manufacturer recommends.

Centennial motorists should read their owner’s manuals carefully to see if it’s acceptable to use lower grades. With some cars, trucks, and SUVs it is; the engine control computer can adapt. You will lose some performance, but won’t do damage to your vehicle. With other engines, using a lower grade of fuel could result in serious and pricey damage; so you don’t want to save a couple of bucks at the pump only to pay it out a hundred fold at your repair shop. There is plenty of routine maintenance that needs to be done on your car to keep us busy without you breaking it!
Your car will run best on the type of gas recommended by the manufacturer.
Today’s computer controlled vehicles are optimized to run well on the recommended grade of fuel. Using a higher grade than is recommended will not give Centennial car owners any additional performance or better gas mileage.
Regulations require detergents for all grades of gasoline, so your engine will have the same protection, regardless of the grade of fuel you use. If you do hear some knocking or pinging from your engine, take it seriously and get your truck into Davis Repair. It may be a sign that you need a tune-up or some other repair.
In times of costly gas prices, most car owners are conscious of making their fuel dollar go further as we drive around Colorado. Be sure to use the right gas for your car. Keep your tires properly inflated and your vehicle well maintained and you will get the best fuel economy possible.
