I agree. The detergents and other additives in top tier gas helps to keep the fuel system and valves cleaner over the long run. I used to add Lucas fuel additive to my V1 tank once a month or so until my tuner noticed unusual deposits on my spark plugs when changing them out. He said consistent use of top tier gas was all that was needed to keep things clean.The main difference is in additives. A refinery distributes gas to many different brands with no difference in the refining process. It's the same base gasoline everywhere they deliver.
True. Gasoline in bulk from any /all refineries meets API specifications. Then before delivery to a gas station, each brand of station has its own additive package that is added either meets Top Tier specification or does not.You guys that think Top Tier is a waste of money are smoking some good stuff. All gasoline is the same. It is the additives in that gasoline that make the difference. End of story.
Not sure I understand the question. If I understand correctly, the requirements to meet "top tier" were developed by a group of auto manufacturers.So this makes me wonder...what or whom is "TopTier"? Shell vs Marathon vs Wawa vs Mobil?
Most of Mobil stations around me make glad that I carry in Condition 0
Probably the best quality, hard to argue that. And I used to only get my gas there. Used to. With the way they have their prices, though, I would rather fill up at Costco while adding some Lucas Octane Booster, then hold my finger up as I drive past a Chevron.Chevron FTW
