Rislone Zinc Additive

Adding extra zinc to your oil will throw off the delicately balanced additive package the highly paid chemist's at your favorite oil company worked so hard to make. You may gain one thing with something but you may drastically hurt another.
There's so many areas they have to formulate for I wouldn't touch that additive with a ten foot poll. 99% of oil additives are junk the only two I recommend are liqui moly motor oil saver or ATP 205 if you have leaky dried seals. Pretty much any performance additive is a wallet lightener.

how much zinc is in that stuff? i would consider it for my '67 Porsche
I have a lot of bottles of Rislone ZDDP Additive from the older days when I used to blend my own high performance add packs for flat tappet cams. I use a little now and then or give it to my friends who are building a new low budget engine.
IF I were into using it up, I'd be all over adding a bottle to SuperTech Wally World oil. The ST has decent base stocks, but is likely skimpy on the add pak to make their price point.
Rislone makes good products. you just need to be able to use them where they make sense ...
Rislone makes ZDDP additives and engine conditioner additives (cleaners), which are we talking about here...

Sounds like regular Rislone engine conditioner.
Good stuff, but not the special ZDDP Additive product ...

I've stopped a few leaks with their products over the past few decades.

What happens when our non-zinc AW additives become so cheap that ZDDP is eliminated?
I can see it now - all of those extra RR tankloads of ZDDP are pulled into a building, drained, rebottled, and re-branded as some OTC or aftermarket Engine Saver.

Kendall GT-1 already has all three of those in it, in significant amounts.

Does the 2.7L have flat lifters with extremely high spring pressures? No? Then why the concern about ZDDP levels?
If you are concerned about an engine with sludge-related issues the last thing you should be doing is "dosing" the carefully balanced lubricant, potentially upsetting that balance, with some "Wizard in a Can" as Trav would call it.

IIRC, wasn't the sludge issue a product of coolant getting into the oil? If so, then nothing that goes in the sump is going to prevent sludge as the result of that contamination. Keeping an eye on it and doing a periodic UOA to check for coolant is likely the safest course of action there.
