Characteristics of Top Tier Gasoline
Gasoline marketers agree when they sign on to Top Tier that all grades of gasoline that they sell must meet the Top Tier standards: their regular grade gasoline must be at least as good as premium gasoline in terms of its ability to prevent engine deposits. They must promise the automakers in writing that every gallon they sell has a strong enough additive package to keep an engine free of contaminating deposits. But premium grade gasoline may have yet higher levels of detergent additives. Typically, Top Tier gasolines will contain two to three times the amount of detergent additives currently required by the EPA. The extra additives are estimated to cost less than a cent per gallon.
According to its auto industry research and to automotive journalists, all vehicles will benefit from using Top Tier Detergent Gasoline over gasoline meeting the basic EPA standard. New vehicles will supposedly benefit by keeping their engine clean and running optimally, older vehicles may benefit with increased engine performance and prolonged vehicle life.
