AMRA issues new fuel system advice WASHINGTON—After extensive study of industry data, the Chemical Issues Task Force of the Automotive Maintenance and Repair Association (AMRA) has issued a recommendation on the use of fuel system cleaners.
It advised service shops to suggest that fuel system cleaners be used for preventive maintenance at the interval of 15,000 to 18,000 miles or one year, whichever comes first.
Data indicated fuel system deposits, including those among combustion chamber and valve components, have an adverse effect on vehicle performance, fuel economy and emissions.
The AMRA presented its recommendation, with extensive supporting materials, to officials from the New Jersey Consumer Affairs Department and plans to share the task force's recommendation and data with regulators in other states.
While not endorsing the AMRA's position, the New Jersey officials stated they would not challenge repair shops in the state that suggested fuel system service based on the task force's recommendation.
Titanium use good for exhaust system
COLUMBUS, Ind.—Arvin Industries has developed the use of titanium for exhaust systems.
First used as a structural material in the 1950s primarily for aircraft applications, titanium and titanium alloys are still used in the aerospace industry but are finding inceased usage in other industries as well.
Arvin, a Columbus-based automotive components manufacturer, said the substance's benefits include weight reduction of an exhaust system by about 50 percent, greater rust and corrosion resistance, greater durability and greater fuel efficiency because of the reduction of the vehicle's weight.
