AAA Study Finds Drastic Differences In Gasoline Quality
AAA hired an independent lab to complete 4,000 miles of simulated driving to compare Top Tier gasoline with the cheaper blends. Their findings show that the additive packages in Top Tier gas resulted in fewer carbon deposits than those found in the non-Top Tier gasoline test.
The study also found that there were some secondary benefits to the better additive packages, including slightly better fuel economy and better drivability. The benefits are apparent, but do consumers really care?
