A method is provided for evaluating the delivery and effectiveness of engine performance chemicals and products for reducing intake valve deposits for gasoline direct injection and port fuel injection engines. The engine evaluation tool provides the ability to repeatedly quantify the relative improvements between engine performance and maintenance products through a series of tests in a controlled environment with parameters that simulate intake valve and combustion chamber conditions of an engine. Non-limiting examples of test engine parameters illustratively include air fuel ratio, intake air flow, temperature of sample, oscillation frequency, presentation angle of replaceable sample, and product delivery method that includes throttle body upstream, port vacuum in plenum, and by fuel injector.
