Gasoline Additive and Deposit Effects on the Road and a Ford 2.3L Engine Test 952446

In a 25-car field test, using five different gasoline additives and five car models, differences in IVD and CCD performance were observed. A comparison of IVD levels from the 15,000-mile field test with results from a 100-hour Ford 2.3-liter engine test (similar to the proposed ASTM/CRC IVD test) showed that the engine test generally ranked additives in the same order as cars in the field. IVD weights observed in the engine test were also similar to those in the field test.

During the 15,000-mile field test, NOx increased an average of 17% and fuel economy improved by an average of 2.2%, both as a result of accumulation of deposits. A comparison of the increase in CCD with increases observed in NOx emissions and fuel economy did not show a clear relationship between the amount of CCD and the NOx and fuel economy changes observed. A good correlation was apparent between CCD weight and CCD thickness.
