Premium vs. Regular Gas
Many people ask us, "Will using premium gas make my car run better?"
Let's break it down and see what premium gasoline is all about.
What is Premium Gasoline?
Gasoline comes in different grades, which are determined by their octane ratings. Regular gas has the lowest octane rating (86-87), while premium gas has the highest (91-93). Most gas stations also offer a mid-grade option that falls in between (88-90). The exact octane range can vary depending on where you live because of altitude differences.
Why Do Engines Need Different Octane Ratings?
Different engines need different octane ratings based on their design. 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 car's manufacturer recommends.
How to Choose the Right Gasoline for Your Car
To find out what kind of gasoline your engine needs, you can:
Check the Sticker:
Look at the gas tank filler lid for the recommended octane rating.
Read the Owner’s Manual:
It will tell you if it’s okay to use lower grades of gasoline. Some cars can adapt to lower grades, but they might lose some performance. Other engines might get damaged if you use a lower grade, which can lead to costly repairs.
Your car will run best on the grade of gasoline recommended by the manufacturer. Using a higher grade than recommended won’t give you any extra performance or better fuel economy.
Important Tips
Detergents in Gasoline:
All grades of gasoline have detergents that help keep your engine clean. This means your engine will be protected no matter what grade of fuel you use.
Knocking or Pinging Sounds:
If you hear knocking or pinging from your engine, take it seriously. It could mean your car needs a tune-up or other repairs. Bring your vehicle to David's Automotive Repair if you notice these sounds.

Drive safe!
If your car stalls at stoplights but runs while you are driving, the engine may be having trouble staying running at idle. The cause could be an air, fuel, ignition, or electrical problem.
Yes. A weak battery can cause warning lights, slow starting, flickering lights, and other strange electrical problems. Modern vehicles use many computers, and those computers need steady voltage to work the right way.
If your car squeals when you first start it, the noise may be coming from the serpentine belt or one of the parts that keeps the belt moving. The sound may last only a few seconds or continue until the engine warms up.
If your heater blows warm air on one side and cold air on the other, the HVAC system may not be directing air the right way. This is common on vehicles with dual-zone climate control, where the driver and passenger can choose different temperatures.

If your car smells like gas, take the odor seriously. A fuel smell can come from a fuel leak, EVAP system problem, loose gas cap, or another issue that lets fuel or fuel vapor escape.
If your headlights dim when you stop at a red light, the charging system may need attention. You may notice the lights get brighter again when you press the gas or start moving.
A soft or spongy brake pedal can mean there is a problem in the brake system. The pedal may feel like it sinks too far, feels weak, or does not give you the firm feel you expect when stopping.
If you hear a clicking sound when you turn, a worn CV joint is one of the most common causes. The noise may be louder during a sharp turn, such as when you pull into a parking space or make a U-turn.
If your car vibrates or shakes while idling , something may not be working the way it should.
