% zinc in penzoil

[Kent_P]

Good day all,
I'm new to this forum but had a question. Does anyone know of a chart or listing of the percentages of zinc in modern oils? Most specifically penz 25w50 racing oil. If anyone knows I'd like to here about it.
Thanks,
Kent_P

Last I heard the Racing 25W-50 had somewhere around 1200ppm zinc.

I was told by the local Shell distributor it was 1200 to 1300 PPM as well when I was in there buying Methanol the other day.

Here`s what Pennzoil emailed me recently:

Dear Charles, Thank you for your inquiry. Yes, this formulation would be equivalent to, or better than, the Valvoline formulation which you are currently using. The Pennzoil25W-50 Racing Oil, stock # 3623, contains approximately 1800 ppm ofZDDP anti wear additives. Best Regards,Technical Service- RM

The Valvoline VR1 and other racing oils are nowhere near that level as shown by VOA's.

Just like many Brad Penn oils are not close to their 1500 PPM statement, I think the Pennzoil might be actually lower as well.

Dont get me wrong they are good oils, but the zinc levels seem to be inflated a bit at times from several blenders.
