Some where recently i read a small article in a magazine/or the AMC list??Maybe here?.....about the "EOS" oil additive that GM sells. Part ## 1052367. It comes in a 16 oz bottle. GM USED to sell it as a oil additive,NOW calls it assembly lube. The parts man told me that one. I remember it saying to add one pint when changing oil. Don't remember WHERE i read about it?? I have read before that newer oil formulations do NOT have nearly enough zinc phosphate in it to properly protect/lube flat tappet cam lobes. From what i've read...this is the leading cause of flat tappet camshaft lobe failures!!! Newer engines are roller tappet/lifter. Thus not needing the zinc phosphate. ALSO supposedly the zinc phosphate adds to pollution. Did anyone else see the small article? I wrote the #### down while reading it...just don't remember WHERE i saw it.I know that MC at Bulltear sells an oil that he has blended to his specs with alot more zinc phosphate in it. Has anyone used his oil, OR the GM additive???? Email me directly or call me 309- 338-3210. Thanks alot,Joe Yahoo!
