Zddplus

I was wondering if anyone here has used ZDDPLUS oil additive. What there site states is that this product simply replaces the ZDDPLUS (Zinc Dialkyl-Dithio-Phosphate) that is necessary on non-roller engines. Or would a Rotella-T 15W-40 be better?

 

That's all I use...Rotella 15-40, works great in my motorcycle as well.

 

Mobil Delvac 1300 15W40 in mine, As Patrick mentioned.......My jeep likes it (-:

There is also a small private outfit that offers a 15W40 with a very high ZDDP content, I have not tried it but a search for " Motorhead Motor Oil " should bring up his site.

 

Never heard about Zddplus.
Amsoil now has a special formula high zinc synthetic.
You can read the product description here;

I as well had never heard of ZDDPLUS (they have a web site as well) either until I saw it in a old chevy book, and since I am now into rebuilding my motor due to a spun rod bearing, just thinking ahead when it will be back on the road. I am thinking of the Rotella-T my self because it's available. Thanks to all who replied

I have used that in 4 engines in the last couple months. It is a cam break in aditive.

Here is a link to a TSB from AMSOIL on their recommended products as they do not recommend adding anything to your oil.

 

I'm about to break in a freshly rebuilt 225 oddfire, and searched zddp on ecj5. I have been told that ZDDP is the stuff to get. From researching their website, it seems like they've done their homework. Of coarse, I've learned that the marketing community has been known to lie about product in their advertisements...I know...I was just as amazed to hear this as you are Here's the link to their website http://www.zddplus.com/

 

I just recently broke in a new cam on my engine. I did extensive research on oils for flat tappet cams, and rotella and valvoline racing oil seemed to be the top choices that I found.. I used the valvoline race oil, with the cam manufacturers breakin lube. Everything went smooth, Im using the race oil as a every day oil now, its expensive though

 

I researched this subject a couple of years ago when I became aware of the need for zinc in the oil. I have four "antique" cars, 2 chevy small blocks, and 1 ford 289, plus the jeep. All have flat tappet cams.

The background is that the zinc was removed from the oil to extend the life of the catalytic converter to 100,000 miles, so modern oils are made for modern cars with different mechanical design.

The "vintage" engines used flat tappet cams. The lobes on the cams are tapered from front to back so that when the cam lobe passes the tappet, it causes the tappet to both lift and rotate in the chamber. The zync is essential in this process. Today's oils are "too slippery" and the tappet will lift, but not rotate, causing the cam lobe to wear. Have heard of cams wearing out in 1000 miles.

I run Rislone in all of my engines. I have purchased ZDDP additive, or cam break in lube, but these come in containers which only contain a few ounces. The advantage of the Rislone is that it is in a quart bottle, so I use this instead of one of the quarts of oil at the oil change.

There is a lot of information on the web on the muscle car forums.

I just did a quick search and found a great writeup with pictures.

I believe it is worth the investment.

Far as I know, the Rover V8's are still flat tappet motors.... I'm sure there are others.

 

I'd add it to the current dauntless, but I'm sure it will be of limited use while it's busy pouring oil all over the shop floor.....
