The Effect of Gasoline Additives on Fuel Economy

  • I. C. H. Robinson


Crude petroleum consists essentially of hydrocarbons of various kinds boiling over a wide temperature range. In the early days of the spark ignition engine it was possible to use some of the light fractions as fuel without modification. Similarly it was possible to use selected heavy fractions as the crankcase lubricant. However, advances in engine and petroleum technology over the last several decades have led to the development of more efficient and much more powerful engines which need more complex fuels and lubricants for their operation. The performance of oil products can be improved to a substantial extent by selection and modification of the hydrocarbon structures, but there are practical and economic limitations to the performance levels that can be reached by hydrocarbon processing alone.
