Now I am wondering what I am supposed to put in my '80's brand X's with
slider cams. They have cat. converters. I was just thinking of going
the diesel route with one thats due for a oil change, maybe I need to
do more research?

It seems as if there will eventually be an additive available much like
the lead substitute.

You gave me a idea, and I found this:

FWIW I used to run Rotella in all my cars, actually I am currently
running the synthetic 5W40 version in the Porsche, just passed emissions
earlier this year after 2 yrs. of a diet of alternating Rotella and
Mobil 1 (Rotella is my first choice, but the synthetic is apparently
only available at Wal-Mart, and not my local one either)

I worked for two school districts in AZ one large with many gas & diesel
engines I was director of transportation at the one I retired from. We used
Dello 400 15/40 at both places in every thing gas or diesel for years and
don't remember ever having problem with a cat. I personally had close to
200K on a 93 Chevy pick up and used Dello 400 exclusively and never a
problem.
There may be a problem using diesel oil in a car with a cat but I have never
had one and use it in every thing I drive.

look into using motorcycle rated oils.

Explain the need for Zinc, how does it help the cam, and do all diesel
engine oils have Zinc in them?
Thanks

" Zinc and Phosphorus -- the two primary metal anti-wear additives.
Their purpose is to provide some degree of lubrication for
metal-to-metal contact when oil pressure is too low (such as bearing
surfaces while starting an engine). These two chemicals are usually
packaged together by additive companies for the oil companies to use, as
zinc dithiophosphate (ZDDP), and the oil companies add varying amounts
to different formulations of their oils. Good for your engine, but high
contents of it may foul catalytic converters if present."

many UJM (Universal Japanese Motorcycles) have cams that run in an
aluminum casting with no insert type bearings and requires zinc for
reducing surface wear.

also think of GM's EOS (Engine Oil Supplement) before that is banned
also!
