What oil are you guys running.
please educate a newbie...does the zinc content go for all of our street engines..or just high compression race motors?
I didn't believe all the hype about needing more zinc because we've all been using "regular engine oil for decades...
Then I used my standard oil w/ Joe Gibbs break-in lube on my fresh 440 last spring, long story short: all my engine parts are at the machine shop because of the metal that went through & ruined everything! My # 2 lifters were ground away to the point it looked like they were held to the bench grinding stone!
DO NOT SKIMP ON YOUR OIL! ZINC IS VERY IMPORTANT!!!
The JG break in lube didn't have any ZDDP additive? I've seen cams wipe out even the older oils and with the break in additives added. How big was your cam and what was the spring pressures?I didn't believe all the hype about needing more zinc because we've all been using "regular engine oil for decades...

I'm running the Rotella 15-40 because I still have a stock of the 'good' stuff but today's engines have roller cams and that's the main reason they don't need as much ZDDP in the oil. Roller cams are the way to go these days and then you don't have to worry so much about the ZDDP and just one engine failure with a flat tappet will more than pay for a roller setup....What everyone needs to remember,the zinc quantity in regular oil that was adequate for decades has been significaltly reduce due to EPA regulations,it ain't what it used to be.One of the best examples is Shell Rotella.I hear a lot of guys still tout it,have an analysis done,you will be surprised as to what it is now compared to ten years ago,might change your way of thinking.
