[Chrysler300] ZDDP re-visited-the bottom line/Showtime/55 AMA specs?

["Rich Barber" <c300@xxxxxxx>]

The ZZDPlus website pooh-poohs the diesel oils (and everything else except
their product) due to excessive detergent package and inappropriate
viscosities, among other reasons.  The website is an interesting read but
does not address why their additive adds $2.00/quart to the cost of an oil
change while former and present lube oil vendors can blend it in for
apparently negligible cost.  At $2.50/ounce, it costs
$320/gallon//$13,40/barrel.  It is advertised on eBay, but at essentially
the same price.

One of the most interesting curves presented at the website is the
concentration depletion with mileage.  It's almost as if the ideal situation
would be to bring the concentration up to minimum, then maintain it by
adding a few drops every few miles.  Like good old Marvel Mystery Oil
(except that went into the intake manifold).

Bottom line for me is that it is still pretty cheap protection, especially
if one can buy oil with enough zinc in it to protect our high performance
engines.  I'm going to find some for both my '55 C-300 and my '86 LeBaron
T&C with 2.2 turbo and catalytic converter.  Replacing the cat should be
cheaper than a rebuild.

Michael:  Where do you find spec's on ZDDP content for the oils you favor?

Went to a local car show today, judged by entrants.  Beautiful venue near
waterfront in Benicia, CA.

Results:  
Fords:  19
Chev:  15
Dodge:  2 ('68 & '70 Chargers)
Olds:2 (Both '50 coupes, 1 Best of show)
Chrysler:  1 '38 Royal with rat motor (2nd in class-nice old 4-door
Royal-street-rodded, but stock body-folks do appreciate something different)
Cadillac:  1- '49 Fastback, first in class

Now, if I bagged our C-300, painted it metalflake red, chopped the top,
installed a supercharger and a custom interior, chromed the engine
compartment--do you think those Ford and Chevy owners would vote for
it--maybe.  Would you?  No.  Case closed.

There was a rather interesting '62 Chrysler "Newport" there, highly
customized and chopped--metal flake green, custom interior.  Kinda reminded
me of those overweight and overaged actresses that try to compete with the
young hotties.  Two separate classes and never the twain shall meet.

I met a guy whose dad used to own a '55 Chrysler 300, except it was blue and
a convertible.  Happens all the time.  Folks remember and appreciate the
style and the reminiscences that flood back with viewing our car.  And a few
kids really think the car and its "dagger-on-the-dash" are cool.  That makes
it a good enough day for me.  I met a new 300 Club member there (sans car,
but at my invitation) and he is thrilled with his new purchase of a red F
coupe.  He and it will be a contender after restoration.

Did some 80 on I-680 and it seemed to be just leveling out.  I put 30 psig
in the L-78x15 Remingtons and the ride was a little firmer and harsher.

Questions:
Anyone have a set of the AMA specs that I could get a copy of?  I'm most
interested in the spec's for ENGINE-EXHAUST SYSTEM-Exhaust pipe diameter and
Tail pipe diameter.  

This month's BRUTE FORCE publication has the '56 AMA specs and they are as
follows for the C-72-300 (300-B):
Exhaust pipe 2.25" Std, 3.0" Opt (Rev 12-5-55)
Tail pipe diameter 2.0 (Rev 12-5-55) 

'56 NY was 2" and 1.75" for duals, Windsor was 2.5" and 2" for a single
exhaust with a 2" crossover.  Duals offered as special equipment.  4-bbl
carb was "Power Package" on Windsor 331 poly.

The parts book seems to indicate the exhaust pipes for '55 & '56 300's are
the same, but the tail pipes are different.  Any insights on proper diameter
before I have some new aluminized steel tube rolled would be appreciated.

C-300'ly,

We hashed this subject to death a few months ago.

I want to point out to the group that Bruce is mistaken in his post, where
he stated, "All of todays oils now have zero zinc..." and "...by 2004 no oil
has any zinc as per EPA."

There are several companies which produce and sell motor oils which contain
appropriate amounts of ZDDP for our 300s (and other autos of the period).
They are motor oils which are directed to the diesel engine market. Mobil
and Shell are two of those companies.

I use Mobil Delvac 1300 Super in my "F" and in my '70 Chevelle LS-5 *without
reservation* -- there are more than adequate amounts of ZDDP in that product
(as well as other benefits). Shell Rotella T is nearly identical to Delvac
1300 Super in it's specifications, including the amount of ZDDP it contains.

Both of these products are available in 10W-30 and 15W-40 viscosities.

  For the past month and particularly this past week the subject of ZDDPLUS 
  has been thrashed about but not been totally resolved. Simply put all flat

  tappet engines need a zinc additive .All of todays oils now have zero
zinc,thus 
  jeoparadizing the life of our engines..Fortunately ZDDPLUS has been
developed 
  so that one 4oz bottle added at an oil change will have the exact zinc
content 
  contained in oils up to 1985. Since the mid 90's the zinc content has 
  continually been decreased so that by 2004 no oil has any zinc as per EPA 
  directives.Every member of this club should educate themselves about
ZDDPLUS by going 
  to _www.zddplus.com_ (http://www.zddplus.com) most of your questions 
  will be answered on this site. We are very fortunate that one concerned
car 
  collector footed the bill to develope a product that will save an untold 
  number of engines. There are many ZDDPLUS distributors throughout the
country. PTS 
  Xtreme at 916-739-0510 has ZDDPLUS in stock.......Bruce Toelle
