1.8 L 4-cylinder Turbo

Automobile Models and Years:

1997 - 2004 A4
1998 - 2004 Passat

New Warranty Coverage: 8 years / unlimited mileage (I guess
Audi/Volkswagen voluntarily extended the warranty for their sludger.)

5,000 miles/six months (normal)

5,000 miles/four months (severe)
7,500 miles (normal)

^^^^^^^^^^^^^^^^^^^

There's a second engine for Lexus/Toyota:

3.0 L V6 ( 1MZ ) [Actually "IMZ" appears, but the "I"
                  must be a misprint.  It's gotta be 1MZ.]

Models and years:

1997-2002 Camry
1999-2002 Solara
1998-2002 Sienna
1997-2002 Avalon
2001-2002 Highlander

Same warranty coverage and oil drain intervals as the first
Toyota engine above.

Sidenote: The 3.0 Liter V6 1MZ engine was used in some 2006
Camrys, so I don't know why the '06 model year doesn't appear
in the list above.  The Amsoil do***ent is copyrighted 2008,
so it shouldn't be a matter of old information.  Was the sludge
problem somehow fixed in the 1MZ after 2002 ?

^^^^^^^^^^^^^^^^^^^

For Saab:

2.0 L 4-cylinder Turbo

Models and years:

2000-2002 9-3 Hatchback
2000-2003 9-3 Convertible

Another Saab engine: 2.3 L 4-cylinder Turbo

1999-2003 9-5
1999-2003 Viggen

New Warranty Coverage: 8 years / unlimited mileage

Oil drain intervals for warranty coverage:
5,000 miles/4 months (severe)
10,000 miles (normal)


000000000000000000000000000000000000000000000000000000000

The Amsoil do***ent lists its sources for the above info as
Audi of America's warranty extension letter, Volkswagen of America's
warranty extension letter, AutoSafety.Org copy of Toyota notification
letter, and Saab Cars USA special warranty coverage letter.  Amsoil's
source for the Chrysler/Dodge information is ConsumerRe****ts.Org and
the source for the Dodge/Jeep info is a Chrysler TSB 09-05-00 (I
guess
this is a Technical Service Bulletin issued by Chrysler on
9/5/2000).
Finally, Amsoil got the info for the oil drain intervals to meet
warranty coverage from the "2005 Car Care Guide" put out by Motor
Information Systems.
