Since there has been a few discussions lately on “Top Tier” gas I figured I would share a short article on AAA’s independent study on different tier levels of gas.
“Top Tier” gasoline had 19 times fewer carbon deposits on injectors, intake valves, and in the combustion chamber when compared to regular gasoline and also can have a cleansing effect. The “Top Tier” was roughly only $ 0.03 more per gallon.
The picture is allegedly after a 100 hour test. I find that a significant difference in just 100 hours.
