Do you sweat at the gas pump even when it’s not hot outside? Combine the current state of our economy and Dallas gas prices rising and, if you’re like most people, you are probably feeling the pinch in your pocket every time you fill up. In an effort to save money, some people are asking whether they can get away with using a regular grade gas in their engine. The short answer is: it depends. While cutting corners on gas may be tempting, the best answer to this question is found in the user manual for your car, but here is a breakdown for each fuel grade to help de-mystify their value.
Regular Unleaded
“Regular” unleaded is gas that has an octane rating of 85-87. A fuel’s octane rating is not related to its quality; all fuels in the United States contain an ingredient to prevent deposit build-up in the engine. Put simply, the lower the octane rating, the more quickly the gas is burned in the engine. Regular grade is obviously the least expensive option, but who can get away with using this grade of fuel? Well, the answer is most people. For most engines, unless otherwise indicated in your owner’s manual, filling up with regular is likely to be just as effective as using premium. Using a higher octane gas in an engine that isn’t “high performance” may actually cause damage to the emissions system.
Midgrade Unleaded
Midgrade fuel has an octane rating of 88-90. If your owner’s manual suggests for you to use midgrade, then this is obviously the right choice. Another example of when it might be best to opt for midgrade gas is in the case of an older vehicle that makes a knocking, or “pinging” sound while being driven on regular octane gas. This pinging sound occurs when the air to fuel mixture causes an abnormal combustion in your car’s engine. Using a lower than needed grade of gasoline in a high-powered engine can lead to this problem. Pinging is not only obnoxious, but over time it may damage an engine. If you experience pinging, try experimenting with a higher octane fuel to see if the problem is eliminated.
Premium Unleaded
Premium contains an octane rating of 91 or higher. Although it’s the most costly option, when it comes to premium vs. regular fuel, if you have a high-performance engine, this one is a no contest. High performance cars are designed to run on higher octane gasoline. Not following manufacturer’s advice in this area can and often will negatively affect your car’s performance and, when done over a long period of time, can damage the engine.
When in doubt, consult your owner’s manual. And if you are like most people, and cost of gas has become a concern for you, consider a more fuel efficient vehicle at your next purchase. The Toyota Prius, for example, is the leader in this category, boasting 48 miles to the gallon in city driving.
