Engine performance depends on the care given to gasoline.
Please read and follow our advice.

Since the EPA first established the minimum additive performance standards in 1995, most gasoline marketers have actually reduced the concentration level of detergent additive in their gasoline by up to 50%. As a result, the ability of an engine to maintain stringent Tier 2 emission standards have been hampered, leading to engine deposits which can have a big impact on in-use emissions and operator satisfaction. Currently, many gasoline retailers provide fuels with lower-quality additive packages that can build up deposits on fuel injectors and on intake valves.Others can build up deposits in combustion chambers and may lead to intake valve sticking.These lower levels of additives can have negative impacts on engine performance and responsiveness.

In as little as 30 days, gasoline begins to turn corrosive and its flash point or combustion declines. As deterioration continues, fine particles of debris, water and corrosion are left behind. Subsequently the engine may not start or run well. A complete fuel system overhaul, including carburetor replacement, may be required to fix a problem. Repairs may be costly.

TOP TIER Detergent Gasoline is the premier standard for gasoline performance. The intention of these standards is to create a winning situation for gasoline retailers, engine manufacturers and operators.Gasoline retailers must meet the high TOP TIER standards with all grades of gasoline at all outlets carrying the brand. 

TOP TIER Gasoline Retailers
Exxon Mobil, Shell, Sunoco, Texaco Super 92-94 Octane
