Saving Maintenance Dollars with Lead-Free Gasoline

Motorists who use lead-free rather than leaded gasolines postpone the need to replace spark plugs, exhaust systems, and carburetors, and thus save a significant part of their maintenance dollar. These savings were documented in a four-year test with a fleet of automobiles operated in city-suburban driving, and in a five-year survey of a representative sample of the motoring public. Savings on gasoline-related maintenance over the lifetime of an average car were about $0.05/gal in the fleet tests and $0.04/gal in the survey. 2
