ZDDP Oil Additive ?????
Not many synthetic oils come with ZDDP and in the oil weight you might want.....
Is there an additive on the market that you can add to your oil of choice?

Comp Cams has just come out with an additive that has ZDDP and the other additives to help it work. Check out Comp Cams' website for the info.

There is also this product: ZDDPlus
I purchased the Comp Cams product but havn't used it yet.

I went and bought a case of the now discontinued GM EOS (PN 1052367). I believe it has over 8000ppm Zinc... Call around maybe you can find some still sitting on the shelves.

Valvoline Racing Oil, has Zinc or ZDDP in its series..
Some are synthetic, some are not..
Also, there is a Shell Rotella T that comes in a synthetic which has it as well...

Some of the Amsoil oils that are not API certified still have high levels of ZDDP in them. (Yes, there are advantages to not doing the API certification thing.) Their 10W-30 springs to mind as one with lots of ZDDP. Other brands probably have similar oils but I'm not as familiar with them.
That said, you shouldn't really need it unless you have an old car with flat tappets or aftermarket valve springs that create higher than stock pressures on the face of the cam lobes.
Most motor oils still contain *some* ZDDP. They've just had to cut the levels back to comply with API requirements.

ZDDP and other extreme pressure additives are surface modifiers. They modify bearing and journal surface characteristics to allow lubricants to develop more "oiliness" (an old term) or lubricity and reduce the tendency to scuff and gall under heavily loaded boundary lubrication situations. Camshafts and lifters in high speed engines definitely fit this category due to the high velocities and accelerations required to open and close valves many times per second.

Absolutley YO-EL. I wish I had known about this before Howie made me aware of it by inquiring about this a couple of months ago.---
As I understand it the reason the EPA has imposed ZDDP restrictions is because it tends to clog cat convertors over time and the EPA has recently mandated that cat convertors be good for at least 150k miles.
A side effect, although I'm not sure if it is intended, is the flat tappet engines will now wear out very quickly and all those muscle cars will require rebuilds with rollers. I'm not sure if that can be done...

I have purchased Rotella T for the break-in on my new motor. However it comes in a 15W-40. I will be firing it for the first time probably in January and the temps will probably be in the 30's. I'm concerned the oil will run too thick for first start. Is this something I should be concerned about? If so what would be a good recommendation?

What I have done is make a home-made pre-luber. I used a 10 qt. paint pressure bucket and made a 3' hose with the correct adapters and Earl's braided steel line. I then removed the front oil galley plug, filled the 'pre-luber' with 8 qts of oil, connected it to the plug port, connected my air compressor set for 50 psi and opened the valve. It worked great. I can drain the oil ahead of time and re-pre-lube if necessary. I don't have the heads on yet, but installed the lifters with a lot of cam lube.

I guess I should be ok then. I was concerned about oil viscosity at 0 deg C on the first startup.

So does Mobil1 15-50wt which I currently have but feel its too thick for winter use.
So I want to get some ZDDP and mix it in with a 10-40 synthetic

This link is very informative ....I recommend reading it: http://www.zddplus.com/
It is pretty expensive. 4oz. bottle is $10 and restores 5 qts. of oil to ideal levels. Thats adding $2 of cost per qt !!!!!!!!!!!!
I would need 1 1/2 bottles as my oil changes are 7 1/2 qts or just let the ZZDP levels be less.

I have a new LS2 & I'm using the Rotella 15w40 for the next yr.
(4000 miles)
They I will switch to the synthetic...
No issues with the 15w40 weight here in 30 degree weather, but my car is kept in a 50 degree garage..
