No - I have not done an Analysis on it yet, but I was told the levels are
high enough to protect the older engines.
It's nearing time for me to pull a sample and mail it in.... will let you
know ..........

Do you know what the zinc levels are on the Brad Penn 15W40?

For my last change on the '91 300D I went with Brad Penn 15W40 from LN
Engineering. So far so good but all I have to go on is the pressure at
idle - which looks better than before - but there are so many variables it's
not a great gauge. I'll run a test on it before long and see what the ZDDP
levels look like after ~2000 miles or so.
I think the cost to have 2 gallons plus shipping (Pa to Va) to my door was
around $75.

Grabbed 8 quarts of M1 15w50 yesterday, I need to change the oil in my '78
240D. I like using the 15w50 in the summer as it leaks/is consumed a bit
more slowly.
Anyway today doing the change I learned 2 things,
#1 oil filters from Car Quest are NOT as good as from Rusty - the o ring is
too big and won't seal the canister, fortunately I had a spare. I though I
had a filter from Rusty, turns out it was for a 601
#2 M1 15w50 is no longer diesel rated, SM only. I had an older bottle that
was CF that was probably bought last year (post facelift, so recent). I
dunno if the manufacturer has to continuously pay for certification and they
decided they weren't selling enough to diesel owners or what but I'll run a
short change on this one (I usually go 7,000 on the 240D, I'll go down to 5
or so) and switch back to 5w40 which I hope still has a C certification, if
not it maybe be Amsoil although my local Car Quest has Royal Purple...
