"SOMETHING NEW FOR OLD RECIPS" "In lube oil, 2% cyclohexanone* by volume prevents hard carbon and sludge formation by dissolving carbon and holding it in collodial suspension." So says the U.S.A.F. official publication AIRCRAFT ACCIDENT AND MAINTENANCE REVIEW after field service tests
in reciprocating engines at Harlington and Malmstrom AF bases and WADC laboratory tests. We quote further: "It (cyclohexanone) reduced engine smoking, greatly reduced oil leak maintenance and substantially reduced starter and generator oil seal replacement. Oil screens were free and clean at periodic inspections and there was a decrease in oil consumption. And, of course, it eliminated problems associated with using periodic dilution as a desludging procedure". •as described in U.S. P a t e n t 2,389,608.
