[Mgs] ZDDP

What is the difference between racing oil and street oil? Just the ZDDP? Or
are there other reasons they call it 'racing' oil?
I have been using 'old'
Castrol 10w-40 for years, after winning 2 free cases many years ago. I'm
almost at the end of them
and I guess I need to start paying attention to
these discussions about ZDDP now.... ;-)

At least two people have.

They all
contain ZDDP to a greater to lesser extent.  The Valvolene VR1 that is
available in the UK comes in those cheap plastic containers that reclaimed oil
is sold in, one 5L I bought only contained a gallon, and at least one of my
engines got nosier when I used it.  I'm also very suspicious of some of their
advertising claims, and wouldn't touch it again with a barge-pole.  My 2
penn'orth.

just right for our cars.
