I've been reading that oil manufacturers have been removing zinc from oil. Zinc was used as an anti-wear additive, and was especially important in engines with non-roller valvetrains. I've taken to adding Comp Cams Engine Break-In Additive.

From Comp's website:

COMP Cams® Engine Break-In Oil Additive Extends Engine Life
New COMP Cams® break-in lubricant provides missing additives no longer found in current motor oils

Time marches on... and generally that’s a good thing. But unfortunately, over time, some of the good stuff can get left behind. COMP Cams® Engine Break-In Oil Additive brings back the good stuff, delivering a specially engineered blend of extreme pressure break-in additives that have been removed from current off-the-shelf motor oils. Delivering added protection during the break-in process and beyond for all engine components, including the camshaft and lifters, COMP Cams® Engine Break-in Oil Additive is compatible with any petroleum, synthetic or blended motor oil.

COMP Cams® Engine Break-In Oil Additive extends the durability of internal engine components, protecting against premature camshaft, lifter and valve train failure. Best of all, COMP Cams® Engine Break-In Oil Additive has proven to deliver long term benefits with new or rebuilt engines through continued usage. Simply pour in a bottle for initial break-in, run the engine for approximately 1,000 miles, drain the system thoroughly and then refill with clean oil and another bottle of COMP Cams® Engine Break-In Oil Additive at each oil change. For more information about the COMP Cams® Engine Break-In Oil Additive or any other COMP Cams® product, call us at 1-800-999-0853, or visit us online at www.compcams.com.

 

lucas is better, a guy i work with is big in to hot rods and compcam's and other cam companies zinc additives arent as good as they say

 

A common way to have a 'break in lube' on hand is to use 90w. Very high in zinc and such. Don't know if it still holds true, but when I used to build motors a lot, that was what a lot of us used and w/ no problem. The advice actually came from the help desk of one of the major cam manufacturers for cam break in.

where do you get your oil from? and do they offer 10w 30?

 

I buy it from Advance Auto Parts but I've seen it everywhere, even at my local grocery store.

Yes it is available in 10w30.

ZDDP Plus Oil Additive

After 70+ years, the EPA mandated that all domestic oil producers remove ZDDP (Zinc Dialkyl Dithio Phosphate) from all conventional and synthetic motor oil. If your engine was designed before 1989 the non-roller lifters require ZDDP to avoid premature deterioration. ZDDP also alters bearing and journal surface characteristics to prevent metal to metal contact. Under extreme conditions like a high performance motor, ZDDP reduces the tendency of parts to scuff or gall under heavy loads. Simply add ZDDP-Plus to every 4-5 quart oil change and your motor will be protected from metal to metal contact. Add one 4 ounce bottle to a 4-5 quart oil change modifier to eliminate and metal-to-metal contact

 

So, are you guys saying that if I don't "add" zinc, it's not in the oil I buy. This can damage my engine!! I run Valvoline 10/40 dino lube in mine, so what, no zinc in this oil?? Thanks, I want to know if I'm slowly destroying all of my lifters!!

 

your fine. that valvoline HAS zinc, and phosphorous... I think its a waste of money to buy any additive to your oil. you are not damaging your engine
