Abstract: 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.

Abstract: A novel car wash composition substantially eliminates water-spotting. This novel car wash composition is comprised of: a surfactant package which is comprised of a first surfactant selected from the group consisting essentially of an anionic surfactant, a nonionic surfactant and mixtures thereof; and a second surfactant selected from the group consisting essentially of fluorosurfactant, a silicone surfactant, and mixtures thereof; and a substantive polymer that renders the surface to be cleaned more hydrophilic.

Abstract: An auto finish-treating composition universally useful on paint, metal, vinyl and other plastic finishes comprises micronized wax dispersed in a water/organic solvent emulsion also containing silicone liquid emulsified in both the organic and aqueous phases.

Abstract: A finishing composition for restoring the appearance of the aged, painted surface of an automobile comprises an isobutyl methacrylate resin polymer dissolved in a solvent system comprising a low boiling organic solvent and a high boiling organic solvent.
