Phone calls and e-mails usually don't get past 1st base, the best method is a letter to the general manager. In the larger companies it will probably not get anywhere near the "top" but it is on record and it is very rare that you don't get a reply.

I found the blurb on the ZDDPlus site re: diesel vs. gas bearing load/shear factor very interesting, as it had really not been discussed in any of the literature/articles about the new oil/low ZDDP problem. Since my motor is stock, I will still use up the garage full of old formula Rotella 15-40 I am hoarding. If I had a full bore, hopped up engine, I would likely have to accept paying 2-3 times the normal price for oil changes (using the $10 additive, or lower mileage/high priced racing oil), assuming the diesel/bearing-load concept is valid?

I think the ZDDPlus site also talks about too much detergent in diesel oil? I notice 20K miles of Rotella use has virtually scrubbed all the accumulated gunk out of my tired, high mileage 292. The oil passages look like they have been polished!

Y-blockhead,



That was a great link. After reading EVERYTHING they provided, I now think it might be a good idea to alternate between the old Rotella and Penn Racing, since the high detergent in diesel oil may remove the lube film ZDDP lays down? I will also likely use the Penn break-in oil, rather than an additive + Rotella when the rebuild is done.



The link re: "break-in" brings up an interesting point. When breaking in the cam on an engine stand, how much running is enough? Since a load is required for good ring seal, and the break-in run time is limited, how do you decide when to install the motor? John Mummert said the cam/lifters would likely fail within 5 minutes, if a problem exists. If everything sounds good after 10 min., continued running without a load would only compromise the ring seal?

Paul.  I thought the information provided with the additive was pretty clear on the amounts of ZDDP that was being provided if that was the question you had.  The same information is also provided on ZddPlus’s website.  Richard did leave his phone number so you can call him directly if there was something else you needed to ask.

Here’s the website link again.

Richard.  Welcome to the site and hope to see you here again.  It’s good to see a manufacturer of a product step in and speak up in support of their product.  As I mentioned earlier in this thread, I purchased some ZddPlus and am currently using it in a vehicle.  I’d not consider this a test as I purchased the product with the intent of simply restoring the zinc content of the SM oil that’s being used.  After reading the literature regarding the ZddPlus, I had no concerns regarding detriments or potential harm with using the product and felt confident that this was a very good alternative in that it permits me to use an oil that does not have the earlier amounts of zinc within it.  I’ve had very little issue with camshaft and lifter wear up to this point and still doing what I can to alleviate any future issues in this regard as the majority of engines I assemble do still use flat tappet camshafts.

In all fairness to Richard, the absence of simple, published letterhead, used oil analysis reports on the website (indicating the product stays in solution) could have something to do with the nature of ZDDPs' tendency to collect/stick to metal engine parts, which would naturally lower it's concentration over time and lead to misleading conclusions. I'm sure we all understand how difficult it is to launch a new business, and the kind of complicated and expensive double-blind independent testing that would definitively prove the product mixes well will likely have to wait.
