FYI

There is an article in the July issue of Circle Track Magazine talking about flat tappet camshafts and the lack of ZDDP in current motor oils. It's not on their website yet, but their articles usually appear online eventually.

They recommend Royal Purple or Joe Gibbs Racing oils. Or some additive called ZDDPlus. Checked out the ZDDPlus website, lot's of propaganda about how modern oils will ruin your classic engine, how diesel oils won't help anymore, etc.

No need to buy any additives or expensive oils. Just use good diesel oil.

The post about the zinc legend is interesting. But I'm not so sure it is a legend, especially on an engine carry a hot cam. 'Way too many cam suppliers say it is fact and a guy on the turboford board was complaining that his new slider cam was disintegrating. Changed over to Rotella (Diesel oil) and the wear seems to have stabilized. Hard to accept that is a coincidence. Also, he was unaware of the "legend" at the time he mentioned the high wear rate.

But anyway, the only extra cost of using the Diesel oil is maybe a half mile per gallon in gas mileage. Why take the chance?

Valvoline racing oil, kendall oil, royal purple and red line all have enough zinc and phosphorus.

Diesel oils that are NOT california legal have the right stuff.
