Zinc additive??

I have a stock 86 454 ( with about 15k miles)in my camaro..(brought the engine used) with a flat tapet cam.. I was just using regular castrol 10w40 motor oil...And wondering if it's OK..

Do I need to add the zinc additive??

Re: Zinc additive??

If I had a high dollar flat tappet cam engine, I'd step up to the plate and add ZDDPlus to the oil. 4 0z bottle is $10 and treats 4-5 quarts of oil. For some piece of mind, I've been addding STP Oil Treatment with ZDDP with each oil change to my '68's L48. STP declares, "if you use one 15 oz bottle to 4-5 qts of oil, it will provide the same protection as the older motor oils provided. The amount of ZDDP in STP is proprietary." So far so good. Fingers crossed. Knock on wood.

Re: Zinc additive??

Hector You have to use an additive like zddp plus or camshield 2 of the best with the oil you are using now to protect the cam and lifters . On the other hand if you buy a specific motoroil like SPECTRO SUMMIT ORsomone like Scheaffer that was made with the right ammount of zinc and phosphorus then you do not need additive. Check out SCOTT WHEATON,S STICKY on motor oil and camshaft breakin very informative and he has been on this since all of this B S started with cams going bad and the oil issues. We all owe him thanks for his work on the subject. Check out some of my posts on team camaro and chevelle i also wrote on this subject as to what a couple of companies did . ALEX

A VOA was performed on the red bottled STP (refer to link, post# 53) and looking at the results this stuff is pretty much worthless (for zddp) unless you just want to thicken your oil. Cam Shield or ZDDPlus is your best bet (when using an additive).

Re: Zinc additive??

It's a good idea to use an oil with more then average ZDDP in a Roller Retro-Fit FT Block with lifter bores that haven't been trued as you still have to contend with Cam-Walk Forces that tend to be hard on the Lifter Roller Pins - Especially if you running 200/500 ftlb and over springs. Crower HIPPO are Good Lifters but the ISKY Red Zone EZ Roller seem to be the choice for long lasting Street SR Lifters these days - Both are Expensive.
