I don't know why I don't post more often lol, there is always a post that answers my questions I guess!? But I do have a question I think I might just have to ask. I have some Oil that I acquired a while back here in St. Louis, and it's called Venom racing oil. It is manufactured by Hicks oil, out of Illinois. They claim that this 15w40 has 3,000 ppm of zinc. Now I know that's a crazy number, but what if you add it in as a zinc additive to a standard 800 ppm oil to raise that number from 1,200 to 1,500 ppm of Zddp? Considering the fact I have no cats on the exhaust. I wonder if it just might be crazy enough to work?? Lol
 
There must be a reason to raise your ZDDP level. What problems are you having with your existing oil and what ppm of ZDDP do you need to resolve the problem you are having.

If you can answer that someone may be able to help.

If it's same as engine in signature it has a flat tappet camshaft, which needs a high level of zinc to keep from wiping out the lobes

You nailed it! I know I can just run Brad Penn, Amsoil, or my favorite Schaeffers! But I was just wondering what the outcome would be if you did this? This post is just for fun, and curiosity! I actually plan on running YB Pennzoil 10w40 with the Schaeffer's #132 and see how it goes?

Unless he is running higher lift and heavy springs, extra zinc is not needed. Once the cam is broke in the chances of wiping a lobe are pretty much down to quality of the cam hardening as long as a quality lube is used. OP if you are worried Rotella will have more than enough zinc to protect that cam.

Good point, as of right now it's a very mild stock cam and springs. So I think I'm good for now! Maybe I'll do a little experimenting, we'll see? I do plan on changing the cam to raise my low end up a bit, but that's another post. Now on the topic of zinc, has there been any word on how moly, antimony, boron ect. play a role in cam wear without the necessary zinc levels??
 
Right you can use it to bump up the phosphorus level, but I wouldn't go higher than 1,200 ppm.
Of course there are other blending factors to consider such as the resulting HTHS viscosity, VI and TBN level of the oil.
 
Crazy enough to work how?

How big is your sump and what are you currently running? I think regardless using one quart per fill willing bump whatever you're running up a little, possibly two quarts on a large sump. You could probably run it straight in your signature vehicle, but I wouldn't want to.
 
Four quarts of 800ppm oil + 1 quart of 3000ppm oil will yield 5 quarts of 1440ppm oil. That would be about as much as it could stand.
 
I just had a uoa done on my Harley running vr1 synthetic 1259 ppm phosphorus 1500 ppm zinc it was the 20w50

Lol I thought someone would say that. I just said that to be funny, think of it with a "mad scientist" laugh behind it. I know... Not so funny. But anyways, thanks everyone for your replies! And to a few that commented on the additives, that's about what I was going for (in theory) to be between 1,200-1,500 ppm of zinc.
 
Oh and it's a 5qt sump, I acquired the truck about 3,000 miles ago. They had fresh oil in it, but I didn't know what it was? So this is its first oil change in my care. But keep in mind this discussion is more for interest in what if? I know I can just pick up any good proven oil.

I was just going to suggest VR1.
 
Mixing it with another OTS oil should be no problem. It's the same as using RL break-in supplement to boost ZDDP levels. Mix away, but I'd second the suggestion to not go overboard.

I believe that Antimony and Boron are AW additives that work at lower temperatures than ZDDP. They will provide metal protection after a cold start until the ZDDP gets to the activation temperature, then the ZDDP will take over and plate the metal surfaces. Moly is a friction modifier, and it helps with fuel economy.
 
I always advise against mixing two oils together - you have no way to predict the way detergent and additives will interact in your oil system. The viscosity will fall somewhere between the two parts, but certain detergents have a way of pulling other additives out of solution if the additive systems are not designed to be mixed.

The zinc is just an effective counter-ion to stabilize the cross-linked phosphorous anti-wear film - and antimony, ammonium, molybdenum can also be effective at this (though MoDTP tends to decompose into MoS2). Also worth noting is that calcium and magnesium detergents have been shown to destabilize the anti-wear film - so I would not recommend an HD engine oil if you decide to tighten up those springs. A typical HD engine oil has higher phosphorous, but over twice the detergents you actually need.

If you want a high-zddp/low detergent oil built for that application, there are plenty of great oils on the market: Champion (full disclosure, I'm their chief chemist), Amsoil, Valvoline, Purple, Red Line, etc.
