My wife kept saying, "Step away from the order button, Paul, just slowly step away, but I couldn't help myself."
And then along came Rotella Triple T and about 10 threads with Synthetic information and there they now sit, all alone in the dark, just waiting for their time.............
And before I ruin this thread for TR4, no I do not know about the Eastwood ZDDP, only the Moss brand.

Sorry, not trying to be cynical, but I'm not convinced it's as big a problem as it's being made out to be.
For example, check this article out - scroll down about halfway to where it says: "The Zinc Question". Interesting reading that squares with another article I posted here on the Forum a while back, but can't locate at the moment.
https://www.ford-trucks.com/article/idx/1...A_Negative.html
Quoting: "However - and this is the important part to remember - available research shows that more zinc does not give you more protection, it merely prolongs the protection if the rate of metal-to-metal contact is abnormally high or extended. So unless you plan on spending a couple of hours dragging your knee at Laguna Seca, adding extra zinc compounds to your oil is usually a waste. Also, keep in mind that high zinc content can lead to deposit formation on your valves, and spark plug fouling." The article is about motorcycles, which typically turn higher RPM than our cars, so I would think we're covered.
For the record, I'm using Shell Rotella in my TR8; it has a larger percentage of ZDDP.

I bought the ZDDPlus from Moss. It is the same as what Eastwood is offering.
As far as whether or not the ZDDP is neccessary, there is just too much evidence out there that when the levels were lowered, the cam problems started on flat tappet cams. I find it prudent to at least restore the ZDDP levels to where they were before the oil companies started eliminating it. It might be true that too much is no good, but putting back what was once there will not be hurting anything that it didn't hurt before. The reason for initially putting the zinc and phosphorous in the oil was so those elements would be the sacraficial wear items rather then the cam lobes and tappets. I'll use the stuff, and worry less.

Guess I missed that Art, can you amplify a bit ? I started hearing about lifter/cam problems oh, maybe 5 YEARS before they lowered the ZDDP levels in motor oil.martx-5 said:
Even bought my kit from BFE to use Ford lifters before they lowered the ZDDP in motor oil ...

Don't know about you guys but I am running Valvoline Racing VR1 with ZDDP from now on instead of the venerable Castrol. Ain't taking any more chances after my last fiasco.

Yep - that's why the levels were lowered. Not an issue with our older cars.

Bill,
Per the machinists recommendation, I'm running Rotella Triple T for the cam break in, the next 500-600 before the head re-torque and then another 2,000 mile period. After that he said this Castrol Syntec with high zinc for classic cars would be just fine:

ZDDP CAN foul up the catalytic convertor. IF you are burning oil... That is why the EPA went to the API to have them reformulate the oil, in other words do away with ZDDP.
Now modern day oils have different additives that work to prevent wear on modern engines. But costwise ZDDP was found to be the most effective anti-wear additive for flat tappet engines.
Hot Rod did an article a couple of years ago about cam destruction on newly built engines running on non-ZDDP oil.
I myself have seen well over 100 Ford 4.0L sohc V-6's that were in the USPS delivery vans experience severe accelerated wear due to the oil not being capable of fulfilling the needs of heavy duty usage. And a number of 4.6L V-8's(later explorer) suffer the same type of wear..
IATN(International Automotive Technicians Network) has a member who is a forensic engineer who did an article on oil formulations a couple of years ago. He stated that for modern design engines that modern oils are capable. But he did not offer an opinion on early design(which is what we've got) engines and which oils to use in them.
Yamaha motorcycle company still includes the "full load" of ZDDP in their Yamalube oils and I'm sure other motorcycle oil companies do also.... Why? IT WORKS.
