#FuelAdditives

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?

I received a brief but telling email from Mr. Hussam Adeni about a previous Piston Slap. The attachments he sent were an eye opener for someone as chemically challenged (so to speak) as yours truly. As you can see from the man’s resume, this won’t be a discussion for the faint of heart. But let me try anyway, it is a great read if you can channel your inner geek long enough in this age of twitter and rapid fire auto-tuned pop sensations.
