So I was always under the impression that gas is gas and pretty much the same no matter where you bought it, turns out I was DEAD WRONG. There are now brands that have earned the "Top-tier" rating by adding a lot more detergents and better quality additives. I had been using Sunoco fuel and recently did a throttle-body clean-out, @102K miles I was expecting cleaning needed but it was REALLY nasty!. Turns out that Sunoco did not make the Top-tier list and AAA says non-Top Tier gasoline caused 19 times more engine deposits than Top Tier brands after 4,000 miles of simulated driving. link to article,http://www.clark.com/top-tier-gas-stations-clean-engine-aaa
