Bill,
Of course, Red Line is going to tell you that. The oil is a synthetic, and I
have seen many, many posts on the migration to synthetic and it just scares me.
I already have a drip rug under the 72 TR6 to check fluids as we speak.
I will post to the list my latest project test. I changed the oil at the start
of summer with Castrol 5W-20 that it has had for 37 years, and added a bottle
of ZDDP.
I requested a test kit from BlackStone Laboratories. It was free but I have to
pay a few dollars for analysis. When I change my oil for the winter, I am
sending a sample to them.
I will share with the list the complete analysis when it comes back. The fact
that Charles and TRF have now started to market and sell the stuff and what he
wrote about it, that he is adding it to his current oil tends to make me think
I am going in the right direction.
List, don't crush me. I know this is a sore subject and don't want to debate
it. Let me pay for the analysis because I am really curious and the list has
saved me many $$$$ (please don't close it), so I want to give back.
As for British car shops in the Washington DC area, one says Redline, the other
says Castrol and no ZDDP. For me, I will let the test decide.
Hope this helps!

I decided to go direct to the "horses mouth" about ZDDP, got this
answer from Red Line in less than 24 hours.
Thank you for contacting Red Line Oil, yes absolutely we have good
levels of ZDDP in our oils, the Motor oils including the 20W50
contain 1330 ppm zinc and more importantly for anti-wear protection
1200 ppm phosphorus. In your Triumphs I would recommend and prefer
the 10W40 a better all around viscosity for those engines, unless you
need the higher viscosity 20W50.
