[Vintage-race] FW: What Oil Do You Use?

[Norm 2Bs]

Larry asked me to forward this to the VR Digest as he wasn't able to.

Last year, someone directed me to the Comp Cams site & I have since had a
discussion with them confirming the zinc problem.

Here is the site for LN Engineering and their complete discussion on  
why oils have changed and why conventional oils are no longer good  
for our racing engines.

www.lnengineering.com/oil.html

Due to emissions needs the heavy metals have been removed, and these  
are the components that give good cam break in and long cam life.   
Why do you think that many of the major car mfg's have gone to roller  
tappet cams in their new V8 engines.  It ain't to save production  
costs, it's to save warranty costs for wiped cam lobes.  DUH!!!

Crane makes a break in additive that is necessary if you are going to  
use conventional oil.  It also aides cam break in and life with synth  
oil.  It can be obtained from Jeggs.

CompCam also has a very good paper in their web site concerning oils  
and additives.  Cam life is the real problem cause a lobe can be lost  
in the first few minutes of operation of a new motor if the heavy  
metals are not in the oil.

If you want to use oil, not synth, use Shell Rotella.  It is a diesel  
formulation and still has the right stuff.  Lots of others do not.

Norm, I did a great deal of research on all this 6 months ago and  
offered to do an article in your new mag about it but never heard  
from you on the offer.  HUM!!!

Your friend is living in the past.  He is dead wrong!!!!! He will pay  
for his ignorance with premature cam failures sometime.  Perhaps not  
this engine, but certainly one in the future.

This is not a case of "lets all pool our ignorance", as we so often  
do.  Crane Cams and CompCams, two of the MAJOR cam manufacturers,  
both agree that there is a big potential problem with the latest  
formulation of standard oils with the latest designation.  I forget  
what that is, but I knew when I offered to do the article.

Bottom line is, it ain't the oil thats going to kill your cam early  
in life, it's the lack of proper additives, Zinc and Phosphorous.

CHOW
