AMSOIL P.I.

Newly reformulated AMSOIL P.I. (Performance Improver) provides unsurpassed fuel economy and performance. Today’s fuels vary in quality and additive treat levels.  Although a certain level of detergent additive is required by law to be formulated into gasoline, cost restrictions cause refineries to use low quality additives in the lowest additive concentration (LAC), a level insufficient to prevent deposit accumulation.  As a result, deposits accumulate on fuel injectors, intake valves and combustion chambers, often within just a few thousand miles, disrupting spray patterns, affecting electronic sensors and causing a multitude of problems.
