Ask The Beaverton Car Guy: TOP TIER fuel, the only way to go
By Larry “The Car Guy“ Ferguson
Hello loyal Beaverton Readers!
Thank you again to all of you who have called and emailed. I appreciate your feedback and questions.
I have had a number of calls and emails about vehicles running poorly. While there are many common reasons for this, one easily overlooked cause could be what we put in the tank.
How U.S. drivers choose a gas station:
- Location (75%)
- Price (73%)
- Rewards program (29%)
- Gas that contains a detergent (12%)
- Baby boomers (41%) are more likely to buy a gasoline that contains an enhanced detergent additive than millennials (32%).
- Men (44%) are more likely to buy a gasoline that contains an enhanced detergent additive than women (26%).
- Two-thirds (63%) of U.S. drivers believe there is a difference in quality of gasoline sold by different gas stations
- Only one-third (34%) of U.S. drivers usually buy gasoline that contains an enhanced detergent additive.
- Nearly half (47%) do not buy gasoline with an enhanced detergent additive.
- 18% don’t know if the gasoline they usually buy contains an enhanced detergent additive.
Does the quality of fuel make a difference?
New testing of Oregon’s fuel has uncovered significant differences in the quality of gasoline sold at fuel retailers in the United States. The independent laboratory testing compared gasolines that meet TOP TIER™ standards with gasoline brands that do not participate in the automaker-backed program. The research finds that consumers can clog their cars’ engines by not using gasoline with enough added detergents.
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.
What is TOP TIER fuel?
The TOP TIER program and performance standard were developed to guarantee that participant’s’ gasoline meets stricter standards for engine cleanliness. TOP TIER gasolines are often marketed to consumers as having enhanced, engine-cleaning detergent additives.
To protect vehicle investments, experts urge drivers to use a gasoline that meets TOP TIER standards for engine cleanliness and performance.
According to AAA, “The laboratories were surprised to learn the extent to which detergent additives impact gasoline quality. As advertised, tested TOP TIER gasolines kept engines remarkably cleaner than other fuels we tested.”
Why TOP TIER?
In response to increasing levels of carbon deposits in modern engine designs, the Environmental Protection Agency mandated a minimum level of detergent for all gasoline sold in the United States in 1996. However, some automakers believe the minimum does not go far enough to ensure optimal vehicle performance and their ability to meet increasingly-stringent fuel economy and emissions requirements.
“By selecting a quality gasoline, drivers can minimize engine deposits, increase vehicle performance and improve fuel economy,”
Selecting a gasoline that meets TOP TIER standards.
Following your vehicle owner’s manual and use the correct fuel for your vehicle. Many consumers associate fuel quality with the octane of the fuel (regular vs. premium), which is incorrect.
If you experience a rough idle, especially when the engine is cold, or hesitation during acceleration, it might be caused by the quality of fuel. Try changing to a TOP TIER gasoline for several fill-ups.
Shop around. TOP TIER fuel is only an average of three cents more per gallon. Fortunately, most gas stations in Beaverton use TOP TIER fuel including Chevron, ARCO, Shell, 76, Exxon, and Costco. Portland’s own Tom Dwyer recommends staying away from AM/PM, Safeway and small mom/pop stations until they make the change to TOP TIER.
The good news is consumers can reverse some engine deposits simply by switching gasoline brands, “Performance issues such as rough idling or hesitation during acceleration can often be resolved after a few thousand miles with TOP TIER gasoline.”
This information certainly proves that we do in fact get what we pay for. The less expensive the fuel the more harmful it is to our vehicles: fuel deposits inside the engines, or in the fuel injection systems, clogged fuel injectors, to plugged catalytic converters. We may think we are saving money with less expensive fuels, but in the end, it can cost us a lot more in maintenance and repair costs later down the road.
