hamradio Posted April 29, 2009 Share Posted April 29, 2009 Has anyone tried this product yet? ZDDPlus additive. Someone has been selling it on TM last week but sudenly stopped. I downloaded the TechBrief PDF's, good reading anyway. Sounds like the oil companies are mostly making motor oil for new cars with cat converters and the goodies are slowly being taken out. The ZDDP companents are what we really need for the old steel blocks and rings. Suits replacement to modern oils. Like upper cylinder lubricant we have to put in the petrol tank these days. Check the maker web site for details; http://www.zddplus.com/ Quote Link to comment Share on other sites More sharing options...
