High Zinc Motor Oil

Just did my latest oil change with the 20w-50 version this stuff.

Posting the link below so you all can be aware of another possible alternative.

Interesting, but they do not list the actual PPM for the ZDDP. BMW calls for 1200 PPM. Too much will kill you catalytic converter.

Right Scott, I was looking for an actual reading not the usual Amsoil 'This is the best stuff you can put in your engine stuff'. If you go over 2000 PPM it can cause a white sludge in you engine that will really gum things up (easily done with a ZDDP additive).
I believe that zinc is a good thing for my engine and usually look for oil with a high level, recent legislation has forced the amount of zinc to be reduced in most automotive oils but it's still at the old levels in motorcycle specific and racing oil. I use Mobil 1 Motorcycle oil as it has, if not the highest, then close to the highest amount of zinc (1700 PPM).

Interesting article about oil in the MOA mag a few months ago.

40Wt and above are not as Zinc restricted as the thinner oils.

Valvoline VR-1 20W-50 Synthetic is a great oil (Zinc 1400ppm) and can often be had on sale for less than 6 bucks/quart.

I am running a 50-50 mix of this and the 10W-30 now with excellent reports on Oil Analysis.
