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.

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!!

RenoXJ

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
