Just a thought... With the concern about the elimination of zinc-based antiwear packages from standard passenger car engine oils, why not just add a partial (or full) container of GM Engine Oil Supplement or Crane cam/lifter break-in additive at each oil change? Disregarding the cost, this may be a good way to get the protection that you're looking for. I understand that there's Shell Rotella diesel engine oil, but that may go away some day. Any comments?
I've heard it both ways on the EOS, so I really don't know for sure. The Crane product still has it, though.
Go to your local auto repair shop. Ask them if they carry B&G & get a can of BG Products "MOA" number 111. It has the zinc & anti-wear/scuff additives. I've been using BG Products for 25+ years.
Tom--Do you mean BG #110 instead of #111?? Or is there another product w/the PN 111? http://www.bgprod.com/products/engineoil.html
Patton, it is PN111, comes in a black can. The "Advanced MOA" in the blue can contains no "Zinc". This is for newer cars. Go to www.bgproducts.com
According to a RECENT (23 Jan 2007) VOA (see below), test results PROVE EOS still has zinc in it, no more hearsay or speculation: http://theoildrop.server101.com/forums/showflat.php?Cat=0&Number=808228&an=0&page=1#Post808228 A can of STP has .19% zinc. Valvoline Synpower Oil Treatment has .17 % CD-2 Street Legal Oil Boost has .47%

Tom, The 110 may have less Zinc, but it still must have some. I see it right on the can. http://www.v8buick.com/attachment.php?attachmentid=52132&d=1120261585
So, would I be right if I say that people do, or at least can run a zinc-rich oil supplement throughout the service life of an engine... even if the additive is only labeled as a cam or engine break-in supplement? In other words, there should be no harm in doing so (other than some people consider it an unnecessary waste of money)?
depends on the year of car. if it has a cat on it then it could cause some problems down the road but on older cars i would say that its fine and not a waste if you have a flat tappet cam
BG Products are the real deal, worth every penny. It's a company run by chemists, not beancounters and marketing weenies.
I understand from previous threads that the zinc content in Rotella oil has gone down, but I do not know if the reduction is significant or not. However, has anyone taken a look at Castol's GTX diesel oil? I was wondering if the zinc content and other oil additive content in it was similar to Rotella's formula. The last quart of GTX diesel I picked up was CI-J.
