    hello, i know this does not answer your question, but it is still on topic. zinc wasn't even in oil until 1947. my car was already 12 years old and i never read one vintage article about the cams falling out of these cars back then...hmmmm. regards, tom

    WELL NOW , just to get things authenticated , where did you find that info . I agree about the cars not exactly falling apart back then , but at 50,000 miles they were considered pretty well done for , look for another one. I grew up driveing them . Then the question then may well be why are we getting hung up on the zinc thing now if it was not there in the 30's early 40's? Learned from DA oil Co. that there are different kinds of zinc for different use of the oils they make . More confusion, some oil industry people say ZDDP is a form of zinc , others say they have ZDDP additives without any zinc in it . TED and Kerry came up with contact info to CCCA and the oil they have from DA does says it has ZDDP in it , not just plain zinc , and DA claims it will protect the old engines , at the same time , DA sells to the general public one case at a time 2 other oils for high performance use with ZDDP that they say will give all the protection needed for flat tappet engines or anything else . And so at this point what I see is a bit of double talk from suppliers, even the best of them and I'm not hitting on DA , I used to use their raceing oil in my sprint cars and it's good stuf , and haveing been improoved since those long ago days . And so the need is still here for some one REALLY KNOWLEDGEABLE with nothing to gain to answer the question of what oil do we REALLY NEED that the government isn't forceing off the market .

    hello, skinned knuckles did a series of articles last year on zinc in oils..developed during WWII. not in retail oils until 1947. even now the zinc is not out of modern oils but is at a lower level and other anti scuff additives were put back in. in regard to 50,000 miles life back in the day..a LOT of that was due to dusty road conditions and lack of proper air filtration. auto restorer also did an article on ZDDP last year..they accept NO advertising and came to the same conclusion as skinned knuckles..unless you have some wicked hot cam with high valve spring pressures installed... our cars are fine on the modern oils. this subject showed up on the british car forums about a year before folks here started to talk about it. it started with a letter from a crane cam employee. cam cams...now bankrupt and out of business, said they were seeing high wear on their cams...hmmm..let me see..company in financial trouble..problems with their product..hmmm..it has to be the oil..it couldn't be they are buying cheap steel or short cutting their manufacturing processes...let's blame the oil companies they got loads of cash....seems suspicious to me. any way crane cams disappeared shortly after but the effects of that letter are still being felt.

    i have yet to see any independant lab test results of the ZDDP additives. if the oil companies did not just dump ZDDP into the oil prior to going in the can, why do owners think they can get the same results by dumping this gunk in their oil pan? my two cents.

    in regard to DA oil having zinc..all oils still have zinc..just a level lower than before..but they did add back other anti scuffing agents.

    regards, tom

    Good research and conclusion TOM . Haveing been continueing the search for answers while this post is active , what I can find from the oil companys is that the levels of ZDDP in most of their oils has been reduced due to a lack of need in modern engines and production costs of the oils . If we use their oils formulated for raceing/high performance or the old car market there is no need for any further additives. And that the addition of over the counter ZDDP will bring any of the oils up to the needed anti scuff level with a figure of 1600 pp or something like that {don't really know what they mean } needed . So if in doubt about your oil and tend to be paranoid DUMP IN SOME MORE ZDDP , can't hurt anything and will insure you have enough . Cost wise buying the specialty oils and adding ZDDP to any oil comes out about the same . With this caution , the oil companys say there are different formulas of ZDDP they use so if your use is high performance their oils made for that use is the safest way to go , high heat being the critical factor . Thanks to all for input and research . BUD

    Stop reading all this junk about ZINK. I rebuilt my Hudson Hornet flat tappet 308 CID engine in 1997 and now 2009 have 129,000 miles on this engine, it's a cross country driver, open highways and speeds 70 to 90 and it has never been touched. Still has the same oil pressure as the day I started it. I broke it in driving to Florida from California, started with Castrol 10-30 for the first 1,000 miles, then changed to 10-40 and at 50,000 miles went to Castrol 10-40 SYNTEC-BLEND. Still goes 3,000 miles between changes and still runs strong. Ask anyone in the NOR-CAL HUDSON CHAPTER. The Zink is needed for Chevy engines because they wear camshafts out. Walt.

    I agree whole-heartedly with Walt. How many times does this subject come up? I rebuilt my first '29 Hudson in 1971, after it had done over a million miles as a daily service car. The cylinders had been sleeved back to standard after many rebores, due to the non-existent air-cleaner and dusty roads, but the cmashaft had no traceable wear on it, and the crankshaft was still standard, though by that tiem quite out-of-round. No multi-grade oils or zinc addtivies in those days, just straight grade oils which used to sludge the sumps up badly. Step-down and Jet motors do have flat tappets admittedly, but the followers are slightly off-centre from the cmas, so they revolve, so have a very soft action against each other. The engines that do suffer bad cam and follower wear are the '34 -'52 splasher engines. These are a direct friction action against each other, and I have seen these verybadly grooved and worn. However, any good modern multi-grade oil willl protect thse adequately. I use either Valvoline, or Castrol GTX, whihc are rated SG, and are 20W-50. Which means they flow like 20 oil when it is cold, or 50 oil when it is hot. Oh, yes, I still throw orange skins on the front lawn to keep the elephants away too!

    Very good and respected testimony of oil products used . The products mentioned DO contain ZINC in one form or another . There are other modern oils that also contain zinc . Visit this site for info on nearly ALL modern oils , ---micapeak.com/info/oiled--- I think all will find it quite enlightening on the subject and tell us what oils to use , with a choice of several . With all due respect I do not find a quest for info on any subject a waste of time , nor an indorsement of a particular product as all inclusive . BUD
