Premium Gas vs Regular Gas: Which One Should You Be Using? 

Estimated Read Time:
‍What is the difference between premium and regular gas? The chemical components between premium and regular gas are what differentiate them. These properties are important to recognize because using the correct type of gas is crucial. 

Premium gas is a higher octane of gasoline (typically octane level of 91 or greater) which is typically used for higher performing engines. However, since the gas is higher quality, this does not mean it is necessary for every car type. What are the benefits of premium gas? Premium gas has a higher resistance to engine knock in luxury and performance vehicles with turbocharges or high-compression engines. Therefore, making the transition more smoothly when pushing the horsepower. Another benefit of premium gas is that it increases fuel efficiency, meaning it could decrease emissions and bring better mileage. However, these benefits are only seen in vehicles that require premium gas. If you are using premium gas in a vehicle that does not need that grade of gasoline; this can eventually ruin the engine or display no change. Especially, if the engine isn’t designed to properly take higher grade gasoline then it will be a waste to spend extra money on it. 

Regular gas is a lower octane level, specifically an octane level of 87. Lower octane gas is used for standard engines that are not requiring premium gas. What happens if I accidentally put premium gas in my car? Vehicles that are not requiring premium gas will not show extreme negative affects. Their engines are not equip to utilizing the premium gas properly, therefore,  it will be a waste and unnecessary expense. If your engine is causing issues, putting a higher grade of gas can help resolve problems, however, reach out to your mechanic to inquire about this solution or if further issues arise. 


How do you know what type of gasoline your car takes? 

Normally this information is labeled on the fuel door stating the type of fuel or grade of octane that is required for the vehicle. However, if you cannot find the information labeled, then check the owner manual to find further information. 


What happens if I put the wrong type of fuel in my car? 

Accidentally putting in the wrong grade of fuel won’t be the end of the world. For example, putting premium gas (octane level of 91). However, putting the wrong type of fuel can cause further issues. For example, putting diesel in a car that does not take that fuel type. This is called misfuelling. For example, diesel is toxic to gasoline fuel systems, and vice versa. If this happens, it is important to remember to NOT START YOUR ENGINE. This will avoid the wrong fuel from being exposed to the rest of the engine. The less exposure the better, in the long run, to repair and remove the wrong fuel. The best thing to do to repair this issue is to drain the tank or bring your vehicle to a mechanic shop. 


What can you do to save gas? In other words, how to drive more efficiently: 
  1. Accelerate gently 
  2. Maintain a steady speed
  3. Avoid excessive braking
  4. Use air conditioning sparingly
  5. Avoid high speeds  
  6. Change air filter 
  7. Lighten car load 
  8. Avoid idling your vehicle 
  9. Check tire pressure
  10. Avoid reviving engine
