    I know the oil companies change their formulations from time to time... What’s the latest news for high ZDDP oils in 2020? Right now my Skylark with rebuilt 462 has Valvoline 10W-30 conventional oil with a bottle of Lucas TB Zinc Plus added to it. I only have about 700 miles on the motor and plan on changing the oil once a year since I hardly drive it. What oil has equal to or more ZDDP than my current set up. I’d like to skip having to buy the separate bottle off ZDDP additive if possible. Also, I’m a huge fan of full synthetics, but should I stick to conventional oil on these old school motors?

    If you use conventional oil you can use STP oil treatment it's the zinc additive there's also an STP oil treatment for our older cars with more zinc additive.

    Driven (Joe Gibbs?) and Brad Penn both make a good, high-zinc oil. I think Lucas does as well. The Valvoline VR1 and their motorcycle oil have quite a bit of zinc.

    It isn't hurting:) My engine builder broke the motor in on BR-30, and recommended the HR-2 10W/30. I used that for a year and then switched to the HR-4 synthetic. That's my story and I am sticking to it.:D

    Interesting video with lab tests. This might not be popular, but STP isn’t what its cracked up to be.

    I use STP at work as assembly lube but I would never dump it in my performance engine. I like Brad Penn or VR-1.

    1972Mach1 Just some M.M.O.G. guy.....

    I use a gallon of Rotella 15w40 diesel, top the rest off with 20w50 Napa (Valvoline) conventional, and put half a bottle of whatever ZDDP additive in it. Usually Lucas brand, because, you know.....

    I was dumping the last bottles of ZDDP I had in my 1987 boat engine.

    Not so fast Slim:D, A cut and paste from JW's oil tech post,

    http://v8buick.com/index.php?threads/new-oil-tech.222499/#post-1797742

    (Last 3 paragraphs )

    "And finally, a lengthy discussion was held on hydraulic roller cam motors. Since the audience was filled with Chev and Ford engine builders, the majority of their customers have gone to these now.

    While the need for high ZDDP/low detergent is greatly reduced in these engines, he has some data from Comp cams, which indicates that even with the high performance roller cams, it's still a good idea to have flat-tappet friendly oil in the engine. What they are seeing is "tracking" of the wheel into the camshaft, as well as accelerated rates of roller lifter failures, when modern API certified passenger car oils are used.

    You still want an oil with the high levels of the extreme pressure additive (ZDDP) and low levels of detergent. That was news to me, as I was mistakenly thinking we didn't have to worry about that anymore, with the roller cams we now have for our Buicks."

    Just following my engine builder's recommendations. Like I said, it isn't doing any harm, and I would rather be safe than sorry.
