<VV> STP Trick WAS Best Oil & STP

[Dennis Pleau]

I've probably overhauled a couple dozen engines in my life.  I used STP as
an assembly lube on all but the last few.  I'm not sure why I changed.  I
never had any problems with STP.  I never used it as an oil additive, just
for assembling them.  My father suggested it when I was doing a bearing and
ring job on63 84hp when I was 14.

STP Corporation sales people have been using the screwdriver trick for a lot
of years.  I was about 12 when I first saw it ... that would be 57 years ago
and it was not new then.  Its ingredients were their secret then and they
still are. I have been assembling street and race engines using STP as
assembly lube since I was a teen ager.  Now, I am not so sure ZDDP is all
that important on a Corvair engine.  There is just not all that much seat
pressure with which to deal compared to the spring seat pressure on an big
valve 8,000 RPM race engine.  

Interesting thing is the STP is still present when the engine is
disassembled ... even after quite a lot of mileage.  You can feel it!  And,
on the dyno, STP engines will pull more power when compared to using factory
assembly lube.

It does take a bit of effort to ad it to an assembled engine.  If ya just
dump the stuff in it will settle in the bottom of the pan.  Ya have to be
running the engine pretty hard meter the STP in gradually.
