In tests conducted independently by SHERIFFS' CARS CONFIRM DIRTY EXHAUST EMISSIONS "CUT APPRECIABLY" BY CHEVRON WITH F-310 "We have used six sheriff's automobiles and a definite improvement in the emissions has been shown. The hydrocarbons and the carbon monoxide have been cut appreciably.' This statement is from R. O. Sudduth, Director, Mechanical Department, County of Los Angeles. It is contained in his letter of March 5, reporting to Los Angeles County Board Supervisor Kenneth Hahn on the County-sponsored evaluation of Standard Oil Company of California's F-310* gasoline additive. in a press conference March 6. Mr. Sudduth explained how the tests were run The cars were 1968 and 1969 models. Two from the Bellflower sheriff's station two from the City of Commerce. two from East Los Angeles This was done to make sure the cars chosen were typical of vehicles subjected to all types of driving-stop-and-go, idling, long-distance and high-speed All cars had been driven 30.000 miles or more. and had very dirty engines. The cars had been run on their usual gasoline. They were switched to Chevron gasoline with F-310, and driven in normal service for as little as 678 miles, and as much as 2093 miles. Careful measurements of emission levels were made before and after the test at a federal government laboratory The chart at right reveals the official test data from this independent research. conducted by Mr. Sudduth. It clearly confirms that both hydrocarbon and carbon mon oxide exhaust emissions were cut appreciably in six sheriff's cars, by using Chevron with F-310. Additional test work is continuing. Independent tests are also being conducted by other State agencies on larger numbers of cars. These data should make it possible to provide an estimate of the total improvement in automotive exhaust emissions that would result from general use of F-310. Published as a matter of public information by Standard Oil Company of California Chevron The enclosed report entitled "Evaluation of the Effect of Chevron F-310 Gasoline Additive Package on Exhaust Emissions and Fuel Consumption" is transmitted for the documentation of tests performed at our San Bernardino laboratories. These tests were performed in accordance to Scott's Proposal 0201-91768-32 and Proposal 0201-12-968-40, under our Project Number 2809 and Project Number 2849. The report describes the test procedures used and the results of 14 tests conducted by Scott Research Laboratories for evaluating the effect of Chevron F-310 upon exhaust emissions, fuel economy, and condition of positive crankcase ventilation valve (PCV). The tests were performed over a period beginning September 1968 and ending November 1969. It was a pleasure for Scott Research to work with Chevron Research Company on this most interesting program.
