How long do you guys run it? What oil additive are you adding for flat tappet cams? I used my last bottle of EOS in the break in oil and need a replacement. Has anyone seen an independant analysis of ZZDPlus?

Thanks, Justin

Brad Penn break in oil per cam manufacturers specs, then Brad Penn oil which ever weight you choose and thats it...imo

I like to use the Joe Gibbs Racing oil "BR" oil for break in of new engines that use flat tappet cams. The Joe Gibbs guys told me to run it for 300-500 miles and then switch over to a conventional race oil. The "BR" oil is basically a 30 WT oil and it has ALOT of zinc and other additives for critical component protection in new engines. Ive never had a problem with cams going flat using this stuff. The Joe Gibbs guys told me to use it on the piston rings and cylinder walls also. I tried it on one of my own engines and it doesnt smoke and it tests great on the leak down test.

Joe Gibbs here too. They have a BR, equal to 15W-50 and BR30, equal to SAE30.

They say, run it for dyno time. (2 hrs.)

I also use Joe Gibbs assembly lube on the cam/lifters, rod, main and head bolts.

It's good stuff.

As mentioned above - Brad Penn.

I'm sure the brad penn is better but I've used Valvoline 30w non detergent w/ a couple of cans of STP and it has always worked well for me.Mine cam is a roller though.

Thanks guys. I already have the oil, it's Caterpillar 15-40 the lab results show it at 1300 ppm on the zinc. Just looking for an additive to help out.
