All brands except for non detergent "SA" oils.
An owner's manual specifies the specific formulation additives to use?
How does average joe know where to find that.

^^ Yep!
All my outdoor power equipment is on a steady diet of 15w-40 diesel oil (various brands)

All readily available oils from any of the majors have at least some Zn (~800 PPM). HDEO's generally have more (~1,200 PPM). xW-40's generally have more.
Valvoline VR-1 and Brad Penn/Penn Grade have more and are the ones I'd use for high specific Zn amounts (~1,400 PPM...). Both excellent oils

Some of those lawnmower oils don't even carry api certifications, I'd rather run Mobil 1 high mileage 10w30 than a expensive quart of lawnmower oil that claims to meet API SH/SL or thereabouts
I use PENNZOIL PLATINUM 0W20 IN MY cx5 AND T5 10W30 IN MY 20HP MOWER. ED
the dealer Mazda with moly oil showed 817 ppm of zinc in my last UOA
Lower Zinc levels required for gas engines with Catalytic converters like our CX5
The only zinc-free engine oils I can think of are those for the older GM-EMD 2-stroke locomotive engines, which had to be Zn-free (
As said above, (pretty much) all engine oils use ZDDP (zinc dialkyldithiophosphate) for anti-wear. And whilst we all focus on Zn as the marker, it's really the phosphorus that is important.

I can still hear the V20 EMD's in my head - they had their place in history ...

Interesting. Everyone has always pounded into my head on here, small engines don't need zinc, but I'm skeptical. They may not have high valve spring pressures, but imo they stress the engine oil more than a regular car would with a thermostat and controlled oil temps.

Rederring? Is that a Portuguese word?
