Stick with well-known gas
Q--I have conflicting information on the need for Top Tier gasoline. According to the official site, the gasolines that meet Top Tier Standards contain significantly more additives (detergents) than required by the EPA. The approved gasoline brands include Chevron, Shell, and 76. Further, and the Top Tier Standard is backed by GM, Honda, Toyota, and BMW.
Interestingly Ford is not backing this standard. I contacted Mobil to ask for their feedback and they said that their gasolines all exceeded the Top Tier standards. Mobil also objects to the qualification process required to advertise their gasolines as meeting the Top Tier Standard.
So, my question is: Is Top Tier gasoline a valid enhancement or is it simply a marketing ploy?
A--Both. Mobil is not the only company that has balked at climbing on the Top Tier bandwagon and Ford is not the only car company. Our advice? Buy a well-known brand of gas and you can't go wrong.
