When you’re deciding where to pull over for gas, do you look for the Top Tier logo? Maybe you should start!
Engine-cleaning detergent additives in gasoline really do make a difference and are worth the extra price to keep your car healthy, according to independent laboratory testing from AAA.
The group’s researchers found “significant” differences in the quality of gasoline sold across the country.
Top Tier Gas: These Are the Best Gas Stations, AAA Says
Since the 1990s, the Environmental Protection Agency has required a minimum level of detergent for all gas sold, but some automakers believe the EPA standards aren’t good enough.
To be considered Top Tier, the gasoline must have a higher concentration of detergent added to it.
AAA said it was surprised to find that detergent additives made such an impact on gasoline quality. The group is now urging drivers to use a gasoline that meets Top Tier standards for engine cleanliness and performance.
“Among brands tested, non-Top Tier gasolines caused 19 times more engine deposits than Top Tier brands after just 4,000 miles of simulated driving. Such carbon deposits are known to reduce fuel economy, increase emissions and negatively impact vehicle performance, particularly on newer vehicles.”
Every service station that sells Top Tier fuel must add the detergent package to all grades of gasoline.
According to AAA, Top Tier gasoline costs an average of three cents more per gallon, but money expert Clark Howard says it doesn’t have to be more expensive.
“The most important thing about the report is that many of the nation’s giants of gas discounting sell Top Tier gasoline, including Costco and QuikTrip,” Clark said. “There are many who decide to buy gas only at major oil company stations believing their gas to be superior. However, you can have what the study finds is the best gas at the lowest prices.”
Where do you find Top Tier fuel options? They’re all over! According to Top Tier, about a third of gas stations meet its fuel quality standards.
