A Critical Road Test Evaluation of a High-Performance Gasoline Additive Package in a Fleet of Modern European and Asian Vehicles

A road test has been conducted to quantify the benefits provided by a high-performance gasoline additive package in a fleet of cars representative of Europe, SE Asia, and South America. The emissions, fuel consumption, and engine cleanliness benefits of additised versus untreated gasoline were compared in 15 pairs of cars. A further 6 cars were operated on a mixture of fuels to show the benefits of additised fuel versus mixed fuelling. The design of the experiment was based on a similar road test conducted in 1991.

Through careful test design and execution, it has been possible to assess the performance of the package at a high statistical confidence level. The package provides a high level of inlet system cleanliness, a significant reduction in fuel consumption and reduced HC emissions.
