There has been a debate on whether or not premium gas is actually better for your vehicle than regular gas for a long time. Well now, AAA recently hired an independent lab to complete 4,000 miles of simulated driving to compare Top Tier gasoline with cheaper brands.
The Truth About Cars reported they found that the additives in Top Tier gas resulted in fewer carbon deposits, slightly better fuel economy and better drivability. What do you think about this? Are these benefits enough for you to switch to premium Top Tier gasoline?
