And of course, not changing oil until ten thousands miles on a TJ
under warranty would be silly:

I seriously doubt Mobil would do anything but ignore or laugh at any
request for a new engine or financial assistance for a rebuild if you
claimed your Jeep engine failed while using their Mobil 1 EP oil and
Mopar voided the warranty due to use of a non-certified oil.  And if the
oil change intervals were at 10,000 miles, Mopar would void the warranty
for that reason alone.  And if Mobil's Mobil-1 EP didn't meet all of
Mopar's SAE certification requirements for an engine lubricant, Mopar
would dishonor the engine warranty in that case too.  For any automotive
engine manufacturer to warranty a blown engine, you had better have
written receipts for either oil changes or oil and filter purchases in a
quantity sufficient to indicate the oil had been changed often enough to
meet the engine manufacturer's oil interval change requirements.

A recent thread on an Internet-based Jeep forum talked about the same
problem with Amsoil refusing to help after an engine blew using their
oil.  Amsoil reps have always claimed Amsoil would cover an engine if it
failed while using their oil and the engine manufacturer voided the
warranty because many of Amsoil's products haven't been SAE certified.
Amsoil basically told the guy to go pound sand, refusing to help in any
manner.

If you're going to expect an engine manufacturer to honor an engine
warranty, you had better be able to prove you met every requirement in
the owner's manual. And if you expect an oil manufacturer to help if the
engine manufacturer voided the warranty because the oil didn't meet the
engine manufacturer's published requirements, you need your head
examined. :)

Thanks,

Yes, I have read all of the text on the Mobil Oil web-site.  No problem with
that.  Or DC really...

I guess it's up to the manufacturer to say yea or nay.  But how do they know
what you use?  I  believe the burden of proof is on you.  I guess it's a
matter if semantics (Merriam Webster On-Line Dictionary:  semantics;
se-man-tics; 1, 2, 3b).

???

    And from that site read "Why do you have to change your motor oil
on a regular basis?"

I agree and that is what I was saying.  BUT it does not specify a particular
type (dino, synthetic, blend, et al), nor does it say the oil must be "new"
(in your document).  Only the weight and frequency.
