I would like some recommendations for oil for my new engine build...... High zinc oil!!
From what I'm reading with flat lifters you kinda need the height zinc for wear...... If this is true, is there a oil that would be recommended to run all the time that had a high zinc level????
I don't mind spending a little more money for better oil!!!

Joe Gibbs is a great option . However , it is hard to find in your Napa and Zone style stores . We use Shell Rotella 15W-40 or you can use Valvoline VR1 . Both of these can , for the most part , be found at those common parts stores . We also add a ZDDP bottle for our first break in . Most of our engine builds for the last 25 years we have used the Shell Rotella due to it being very easy to get where we are .

Here is some information about the Valvoline high zinc oil .

What solutions does Valvoline offer to the zinc issue?

Valvoline offers two solutions to the zinc issue:
Valvoline VR1 Racing Oil: Contains 75% higher zinc than SM motor oil with a balanced additive package designed to work in both racing and street-legal applications. This product will protect older style push-rod and flat tappet engines. Valvoline provides this product in both multi and mono viscosity grades: 20w50, straight 50, 10w30, straight 30, straight 40, and straight 60.
Longer-Lasting Zinc/Phosphorus: Valvoline uses an advanced zinc/phosphorus additive that keeps higher levels of phosphorus in the motor oil where it protects the engine instead of poisoning the catalytic converter. Valvoline is the only brand offering this unique additive across its entire line of passenger car motor oils including SynPower -- the only synthetic oil that offers this additive.



Which oil has more zinc/ZDDP: VR1 or "Not Street Legal" racing oil?

Valvoline VR1 Racing Oil contains .13 percent of zinc and .12 percent of phosphorus compared to the Valvoline "Not Street Legal" Racing Oil which contains .14 percent of zinc and .13 percent of phosphorus.

Run to Rund

I use Chevron Delo 400, 15-40 in the old CI4+ formula that doesn't meet CJ specs (the new stuff has less zinc). I add a bottle of Comp Cams 159 for break in. I use 1/2 bottle of old formula GM EOS the rest of the time.

I always use a zinc additive. Sometimes it can actually be found at your local auto parts store. But most employees these days don't really understand it's purpose. You can also call up summit or jegs and get a zinc additive, break in oil, or a combination of the two.

Beware. failure to use a zinc additive will result in flattening of the cam lobes.

Diesel engine oil still has zinc in it.

I used the same during break in and the dyno run. There after I use an additive by Compcams.
