Researching top tier gasoline I find a list of 76 gas stations that sell it.
I find there is really no definitive standard as to how much detergent is added, the active ingredient in the detergent and what's the concentration.
Phillips 66 claims they have 3x the minimum detergent required by the EPA. So does that mean that all gasoline has some detergent mandated by EPA? If so, what is the minimum concentration? And what is the detergent?
Marathon has King Richard promoting STP fuel additive.
Is King Richard's STP fuel additive really better than SeaFoam? Or are they all the same detergent?
There is no question in my mind that keeping valves and pistons clean and free of carbon is necessary.
If I can buy Kroger gasoline for my old tractors, with a dollar off a gallon using their fuel rewards points, what fuel additive and what concentration should I use to bring it up to Top Tier standards?
