Our motor builder said we need to use a motor oil that contains zinc, but usually only racing oils contain zinc.
What quality does zinc have that makes it essential for racing engines?

Thats a pretty good article and should be read by all gear-heads and racers.
Alot of the Sprintcar community uses Pennzoil 25w-50 racing oil. The oil still has to be changed every 3 races or so as the methanol gets in the oil a mixes, which for obvious reasons is not good, and creates a creamy looking color. Your engine "builder" should have either dynoed your motor (with appropriate oil) or suggested a brand name and weight to be used. There are alot of different racing oils out there and all or most of them have some sort of anti-wear additive and should be suitable for your use.
Good luck!
The older I get, the faster I used to be.

Thanks for the info, thats good stuff.
Our builder did recommend Brad Penn oil, and it seems to work pretty well. Its funny because Brad Penn was one of the oils recmmended in this article. I was just curious on the reasons for needing zinc.

Not sure about zinc but I know Sunoco has a 20w50 specifically for methanol burning race engines. Cost more than 20w50 at Walmart but what's your engine worth? I'm sure other oils would also have methanol specific oil as well.

If you want some of the best lubrication around, look into Joe Gibbs Racing Oil, you will be able to find the exact oil for your particular application. And you will have your zinc protection as well.

The zinc issue has come up on the traditional rod forum boards too. Seems the (aftermarket) solid lift/flat tappet (?) camshafts need the zinc additive for lubrication.
The newer cars on the road have gotten to where they don't seem to need zinc additives as much, and the oil companies are looking to save a buck on additives.............

Joe Gibbs has always been a leader in lubricant technology. His countless hours in the lab and dyno room are second to none.

I say Lucus oil products,Valvoline,and Amsol ... all proud sponsers of sprint car racing series,stand behind the people that work to make racing happen..zinc was removed because it causes early failure to cat coverters and ox sensors-of course not a problem in race engines

the epa is to blame. claims zinc pollutes! car manufacturers have gone to roller tappet cams or overhead cams therefore don't need as much zinc.
on street engine,use lucas oil additive,peace of mind.
to be safe use the additive on any engine (street use) with flat tappet cam.
