Stocker Flat Tappet Oil....
 

What oil are you guys using for "dial-in" every day racing? I want to make sure to protect the camshaft from premature wear and any recommendations are appreciated. I've heard some oils dont pump the lifters up very well. Has anyone found this to be true?

Thanks for the info.....

What your looking for is oil with the highest zinc content, Valvoline and Joe Gibbs are two I am sure there are more.

Re: Stocker Flat Tappet Oil....
 

Joe Gibbs oil ssems to work well.

Re: Stocker Flat Tappet Oil....
 

My brother-In-Law uses this on every motor he builds. He has been seeing alot of bearing problems due to lack of Zinc as well.

Amsoil has several high zinc content oils. These are the ones I'm sure of:

Shell Rotella T seems to work well for me in all engines, and very cost effective too

Re: Stocker Flat Tappet Oil....
 

the oil is not the cure its the additive package in it 80% of a quart of oil is mineral oil the other 20% is additives thats what makes or breaks the oil i and at least 20 other guys at my ome track have been using moa by bg for years and it works awesome

and it cost around 6.00

Re: Stocker Flat Tappet Oil....
 

Rotella T and Delo 400 diesel oil work good as long as you can find some of the older stuff, I here the new diesel oil is going lower on the zinc also. I do know that Brad Penn racing oil works good, a friend of mine runs it in his stocker with alot of spring pressure and has had zero problems with his cam. We broke the cam in with Brad Penn and the GM EOS. But I'm sure there are plenty of other good racing oils to use. Shawn

Re: Stocker Flat Tappet Oil....
 

Wade, use Valvoline Part# VV-850 it is 10w30 weight oil and it has good Zinc in it, I use it all the time for break-in and when I switch to (go fast oil) I dont really pick up that much,great oil.Make sure it is Part # VV-850. Most NAPA stores have it.

Re: Stocker Flat Tappet Oil....
 

Thanks for all of the good info......

Re: Stocker Flat Tappet Oil....
 

I highly recommend the Valvoline VV-850 10W-30 Racing Oil also. I found it to help in the rocker arm "ball" area too,on my Chebbie. Acts almost like a synthetic when it is warm, in that you will not lose oil pressure like most regular oils. Like in the previous post, get it from NAPA and save yourself alot of money over the Mail order places.

Re: Stocker Flat Tappet Oil....
 

I for got to mention that Comp Cams sell a zinc additive for break in , can be used with any oil. a good alt. product.

Re: Stocker Flat Tappet Oil....
 

Bradd Penn is the old Kendal green oil.It is recommended for flat tappets,lots of zinc.I believe it is the old SJ designation.Great oil reasonably priced.

Re: Stocker Flat Tappet Oil....
 

On my hot rod for the street I have been using Shell Rotella 15-40W and not have had any cam related problems but, I have had this case of oil around for a while. I was told that the the Feds were after the diesel oil manufacturers to lessen the amount of zinc in their diesel motor oils. Does anyone know if this has happened yet?

By the way we use Royal Purple in the race car.

Re: Stocker Flat Tappet Oil....
 

Is anyone using Lucas Oil Products - "Engine Break-In Oil Additive" w/TB Zinc-Plus. How do you like it? Plan to use it in next oil change. Lucas says key benefits are:

Excellent for flat tappet camshafts during break-in or as an additive to any motor oil to prevent premature wear.
Exclusive blend of extreme pressure additives.
Add one bottle with every oil change to increase the zinc content of your motor oil.
Designed for race applications requiring additional extreme pressure additives.

Purchased mine at Advanced Auto.

Re: Stocker Flat Tappet Oil....
 

njk53......yes it has, check before you buy any new stock.

Re: Stocker Flat Tappet Oil....
 

The new diesel oil, spec SJ, came out along with the Jan 2007 introduction of particulate traps for diesel pickups. You want to find the older spec oil, CI4+, that does not meet SJ. the oil companies get away with saying the new stuff is backwards compatible and meets CI4+ spec, but the new stuff has different additives and a major reduction in what we want to protect flat tappets. Most retailers don't have the old stuff anymore, but Chevron distributors may carry the old stuff in 5 gallon buckets.

Re: Stocker Flat Tappet Oil....
 

Thanks for the info Bob P. Does anyone know if the petroleum based racing oils have as much zinc in them as the oils from the pre-government intervention days or do they contain reduced amouts of zinc?

Re: Stocker Flat Tappet Oil....
 

Received information on ZN content from Lucas Oil Products on their - "Engine Break-In Oil Additive" w/TB Zinc-Plus, as an additive to current conventional oil for drag racing.

o The typical amount of zinc phosphorous in the older oils is somewhere around 1400-1500 ppms:

o If you run a 5 qt system, if you add 1/2 a bottle of the TB Zinc to the 5
qts, it will give you 5,000 to 5,200 ppms of the zinc: and

o Does it hurt to run a full bottle? No, but it is a waste of the product. A half bottle is plenty enough for your 5 quart application.

Questions were for a Stock Eliminator engine running between 5500 and 6500 rpm.

Nice chevelle! What engine / trans combo?

Re: Stocker Flat Tappet Oil....
 

I just found this. It basically outlines the Amsoil synthetics I posted links to earlier in more detail:

Re: Stocker Flat Tappet Oil....
 

One side note, never break in a new engine with a synthetic, run it in with reg. oil first, then you can change to what ever synthetic you want and you will not have any ring sealing problems.

Re: Stocker Flat Tappet Oil....
 

CAM2 lubricants is coming out with a line of "Blue Blood" racing oil, a 0w-30 synthetic, and synthetic blends in 10w30 and 20w50 (and a Nitro 70, if Bailey's reading this!). Zinc levels are 2,000 ppm.

Re: Stocker Flat Tappet Oil....
 

455, Would it be safe to assume that once the engine is properly broken in, you could use a 1/4 bottle of the Lucas Engine Break in Additive? If a 1/2 bottle gives you 5,000 to 5,200 PPM of ZnP, a 1/4 will give you approximately 2,500 PPM which is 1,000 PPM more than that of the old conventional motor oils, or does my mathamatics not work in this case?

Re: Stocker Flat Tappet Oil....
 

njk53, I am no expert on this, only know what Lucas suggested, that was half a bottle in 5 qts. of oil for stock eliminator engine after break-in. Not knowing for sure, do not want to miss lead you, therefor can not confirm your thinking. It may also be that the chemisty of the zn is a factor??

Re: Stocker Flat Tappet Oil....
 

455, it would be interesting to speak to someone from Lucas on this subject. I have two points regarding my statement 1) If a 1/4 bottle of the break in lube is equivalent to 2,500 PPM, which is better than the old conventional oils, why waste the product and spend more than you have to using a 1/2 a bottle. 2) Laws of diminishing returns; how much ZnP do you really need in your oil to prevent a flat tappet cammed engine from damage? If it is 1,500 PPM anything above and beyond that number is also a waste of product and a waste of money. This is a real good thread to discuss.

Re: Stocker Flat Tappet Oil....
 

A 1/4 bottle of additive contributing 2,500 ppm of zinc is diluted by 5 quarts of oil, it would appear to add about 500 ppm of zinc to the overall mixture.

Maybe I'm not saying it quite right, but it should get the idea across, I hope.

Can 455 confirm that? Or does the bottle say the increase is for the total mixture including the5 quarts of oil?
