Let me chime in here. Amsoil's non API certified oil has been tested,
at least the ASL 5W-30 and the results show that there was no effect
on the catalytic converter.

While in theory ZDDP can cause the converter to plug up, the main
reason for them to plug up is something seriouly wrong with the
engine.

Do you often stoop to name calling when you can't get your way? I
searched on ZDDP and catalytic convertors, none of which said ZDDP
from engine oil caused a problem unless the engine had a major
malfuntion.

Tested by whom? The effects on the catalytic converter are long-term,
and occur slowly over time, and depend on how much oil the engine
consumes as it wears.

The limits on ZDDP are because automakers must warranty the catalytic
converter for 80,000 miles. An engine that consume oil well within the
specs of the automaker would shorten the life of the catalytic converter
to less than the warranty period, were an oil with a high level of ZDDP
used. Similarly, a vehicle may make it past the warranty period, but
still have a shortened catalytic converter lifespan due to the high
level of ZDDP. No sense risking it, since even an after-market catalytic
converter would cost well over $300 installed. There are plenty of oils,
both synthetic and petroleum based that provide excellent lubrication
without high levels of ZDDP.

Of course Amsoil is going to jump up and down and swear that they've
never seen a catalytic converter damaged by their non-API oil, but such
statements are not proof of anything. Of the relatively small number of
people using Amsoil, few would ever realize that an early catalytic
converter failure had any connection with the oil they use.

It's always amusing to see a company claim "we are not aware of our
product causing any problems," as if such a lack of awareness is proof
of anything.

Amsoil's API certified oil is probably as good as Mobil 1 or Castrol
Syntec, so if you can get it for a good price then go for it.

Apparently you don't know or understand the difference between a
plugged catalytic converter and one that has been poisoned and is
no longer efficient enough to perform properly.

Not surprising.

Umm, what name calling and what way would that be?

Funny, I got 1260 hits on Google.
Was your computer not connected to the internet or was your
search limited to the public library in Superior Wisconsin which
not surprisingly has been purged of the subject?

Your position is contrary to published SAE papers.
Your position is contrary to vehicle manufacturers warranty
requirements.
Your position is contrary to EPA warranty regulations.

I've searched in vain on the Amsoil website for any evidence that
[their] oils are approved by any original equipment manufacturer
WRT warranty compliance. All I can find is that Amsoil
"recommends" XX product for YY application.
In case you're wondering what such an approval would look like,
scroll down to "Specifications and Approvals" at this web site;
http://www.mobil.com/Canada-English/Lubes/PDS/IOCAENPVLMOMobil_1_0
W-40.asp

THAT is what a legitimate oil specification looks like, not the
weasel words used on the Amsoil web site.
