In August 2005 the Engine Manufacturers Association (EMA) issued a statement saying that the 520 micron wear scar specification listed in ASTM D975 was not consistent with the requirements of fuel injection equipment manufacturers. They recommended that the lubricity specification be changed from 520 microns to 460 microns.
The other night I could'nt think of the EMA for the life me. I think its sad that our goverment will allow our fuel prices be so high and throw a high per gal tax on top of it but wont require the manufactors to meet the EMA's 460 micron specification. The manufactors have a hard time meeting the specs set forth by the goverment you forget about them going beyound it.
