<VV> Best Oil & STP

[Jamie & Tanya Reinhart]

I have been using STP as the final pint of an oil change in corvair engines 
for as long as I have been driving. Learned the trick from my father that 
has been doing the same since he bought his first new corvair in 1962. The 
last bottle I bought specifically had a statement on the front of the bottle 
that it had higher levels of ZDDP. I don't have a bottle around here now to 
tell you exactly what it says. I have also used it many times as an engine 
assembly lube like many of you have. It's great stuff in my opinion.

Odd that the oil topic came up just after a little "experiment" at work.

A few days ago, one of the guys had Regular oil 5W30, Mobil1 5W30, A bottle
of STP and a flat edge (relatively heavy) screwdriver.   He dipped the blade
of the screwdriver into each and had several of us (taking turns and
cleaning hands and screwdriver each time) holding the screwdriver tip
between thumb and forefinger with palm above and handle of screwdriver
hanging down.  Easy to do with nothing on the blade AND with oil on it AND
with Mobil1 on it.  But, even though it was more viscous to the touch, it
was virtually impossible to keep the screwdriver from falling when it was
dipped into the STP.

Now, this makes me think that it might be a good idea to add some (how
much???) STP at oil change time.  I looked at their web site and could not
find any specifications for STP.  I was looking to see if there was a
statement about ZDDP content, but was unable to find anything.

Does anyone on VV have a clue as to ZDDP content of STP and what would be an
appropriate ratio of oil (either type) to ZDDP if adding at oil change time.
I'm not condoning this, just trying to investigate at this point.

Thanks.
