My '61 has solid lifters - need I say more...and I don't want to ignite an old thread on this topic and bore everyone. But, I need an easily available source of a Hi-ZDDP oil (I don't want to use additives) - I have CarQuest, Napa, AutoZone, Advance Auto, WalMart etc. nearby. Do any of these guys have what I need ? Does the Valvoline Motorcycle 4-stroke oil do it ? I want a brand name please that is in one of the stores mentioned - don't just tell me to find some diesel oil. Thanks in advance.

You said not to tell you, but diesel oil (motor oil, not fuel) is probably the easiest to find with higher than normal quantities of zinc.
Shell Rotella-T & Chevron Delo-400 are very easy to get (Mobil also has a good version). They normally are 15W-40, but may be available in something lower. I have been using the 15W-40 for about 6 years now (including my JD lawn tractor), and other than higher oil pressure at start up, have no issues.
The older CH-4 and CI-4 ratings are very high in zinc, while the newer CJ-4 rating has lower amounts, but still better than standard automotive motor oils. Other option is racing oils, but they are typically even higher viscosity and have less additives designed for street use.

fdreano, Go to your friendly GM dealer (Cadillac, Hummer, Chevy, Buick, etc.) and buy some GM E.O.S. Assembly Lubricant over the parts counter. This is a product that GM has discontinued, but is still available by searching the dealers. The part No.is 1052367. Just use any diesel oil you want and add a 1/2 bottle of the EOS and you're good to go. The EOS sells for about $5.00. If the first dealer you go to doesn't have it, have them do a search of other dealers in the area. I found a dealer in Celina north of Dallas who had 2 cases of the stuff and I bought both for long term "no worry". Now, the directions and others will tell you it's not an oil additive, BUT that's because new cars can be harmed by the ZDDP contaminating their catalytic converters. We don't have to worry. Good luck.
One problem with Z&P additives is that they tend to be equally high in detergents. If you add these additives and are already using a high detergent oil such as most diesel oils,you stand a good chance of removing the protective anti-wear coating on engine parts or prohibiting them from forming altogether. I use Castrol High Mileage 20w-50 I get at Advance Auto. It has Z&P comparable to diesel oil in the 1100 -1200ppm range. It also has a additive to soften and swell seals to help prevent oil leaks. It has moderate detergent numbers in the 1900ppm range.
Thanks all I'll start researching these alternatives. I've finally got my vette running 1/2 way decent and I'm a little paranoid over maintaining the status quo now. All I need is my cam lobes worn down prematurely or other mechanical problems.
fdreano, No need to worry. If you've ever looked at the bottom of a new lifter and the contact it makes on the cam lobe you wouldn't worry nearly as much. It looks like they make contact across both their surfaces, when in fact, the lifter is cut on the bottom to be convex (bulging outward) with a very small contact patch on the bottom to make it rotate on the cam lobe. With good oil and filter changes, there's nothing to worry about. By the way, thanks for the 2 x 4 pics you posted previously. Great idea to install just the rear carb to get the mixture sorted out.
Most Wal-Marts have CI-4 diesel oil - brands don't matter.
I get Shell Rotella at the local Wal-Mart (the only thing I buy there). I pick up a couple of gallons whenever I go by there. The wife thinks I'm nuts with the oil I have. Oh well.
i am new to this site. this fall i bought a 66 convert. i also have a 66 skylark gs. according to v8 buick board eos is being sold again.

Gm has reinstated this EOS and the new number is 88862586. Currently it is not yet available but will be soon! Please email us before ordering to insure we can supply you!
EOS - Engine Assembly Prelube
Specifically formulated as an engine assembly lubricant. E.O.S. provides outstanding protection against run-in wear and piston scuffing as well as run-in camshaft lobe and lifter scuffing resulting from insufficient lubrication.
i believe it is about $10.00 a bottle.
thanks jim karnes cols ohio.

Well I figured the car runs on the back carb most the time anyway so it couldn't hurt to have one carb on the engine until I figured things out - car runs fine that way...

Bet it's not the same formula, hence the new part # Plus, no doubt it is for the new engines
A few years ago when they first started messing with the oil formulas I read in one of my magazines that if you are running higher valve spring pressures some protection in the form of GM's Camshaft & Lifter prelube, part # 12345501 was a good idea. I've been using it ever since, one small bottle per oil change - may be overkill but I sleep better now.

What Coves and Plasticman told you was just about perfect. My partners and I own a plant near Manchester England that makes ZDDP, ZDP, and 50 other non-metallic EP additives that all the oil packagers buy to to formulate their oils.
If you will pay the freight, I will give you a 55 drum of ZDDP and you can repackage it and send to all the guys on the c-1 c-2 forum.
I have run my solid lifter 283 for 40 years and 180,000 miles with no problems. I used a spark ignition motor oil with ZDP until about 1980 and then have used diesel motor oil since. Most cam lobe wiping problems are simple bad break in procedures.
The ZDDP tends to break down over miles (as does the non-metallic EPs), just change the oil every 2000-3000 miles and you have all the additives you need.
Now days it is nearly impossible to even buy a bad motor oil.
