<VV> New Oils for Classic cars

[Eric S. Eberhard]

The "safe than sorry" argument is what cost me two cam shafts.  It 
seems people think for some reason it is "safe" to use dinosaur oil 
for break-in and not synthetic.  So they don't know anything about 
ZDDP and then ruin my cams.  Mobile 1 (as stated on their Web page) 
is rated to break in engines.  Some synthetics are not, but Mobile 1 
is.  And it has the correct phosphorous and zinc levels for 
Corvairs.  It is plenty safe to follow my recommendation, most 
certainly Exxon-Mobil's, for using Mobile 1 during break in and all 
around. Note -- not ALL Mobile 1 has the right ZDDP levels -- check 
their site. I use the 15-50 and always have, so I just got lucky, so 
long as I was doing the work myself.  The two bad engines were two 
different mechanics and they insisted on using Castrol 30 wgt ... 
unfortunately months apart ... and both did not make it 10k on the 
cams.  I supposed I could have gotten 2 bad cams from Clark's and two 
good ones when I used the Mobile 1 -- I just think the odds of that 
are small.

But opinions about oil are like belly buttons, everyone has one, and 
mostly they are good for collecting lint.
