Well, I didn't notice you were in Minnesota, so that throws a wrench into using 15w-40 as that appears to be the only Schaeffer Oil which meets VW specs. I know that it performs as a 10w, but I still think you'd be using either a 5w or 0w weight. Do you have a block heater is the car in a heated garage? If either of these is "yes" then you may get away with the 15w-40...but then where do you park your car at work.
Alas, other that using Mobil 1 0w-40, I would recommend GC 0w-30 (German Castrol...do a search, or maybe the Green One himself (pscholte) will appear).

You're right, DB. it's a 2.0 liter Jetta. I was going from memory. Maybe too many beers this last weekend.
Just for grins I went to the Schaeffer's site schaefferoil.com and the Schaeffer's Supreme 7000 10w-30 and 5w-30 meet the following specifications.
ACEA A1-02, A2-96, A3-02 and A5-02
API SL
My experience with Schaeffer's has all been positive. Additionally they are not prone to over hyping their products.

I too received a letter from VoA re: the extended warrenty due to oil sludging and the new oil requirments for the 1.8T. I have read the posts on this site (as well as others) and I really haven't found anything conclusive other than one side seems to say you "must" use the approved oils and the other side saying you can follow the manual regarding oil type and OCI. Here is my situation; since first oil change at 5k miles (recommended OCI) I have been using Shafers 7000 with Napa Gold oil filters adhering to the 5k OCI. I have never once had to top off due to oil consumption, not even during the first 5k miles which I hear is typical of this motor. I now have 36k miles on the vehicle (2003 Passat) and it seems to be running fine, no issues. My question is; because Shafers is not on the approved oil list, am I potentially damaging my motor or will I be okay to keep using my current program? Will a nutra treatment at set intervals (please recommend interval) assist in avoiding this problem. For background, I live in Minnesota so temperatures range from 15 below to 90 above, car is used primarily by my wife for commuting to work about 25 miles one way at mostly hwy speeds. Any clarity that can be added to this question would be greatly appreciated. Thanks for the help.
My stepson has the 1.8L engine in his '97 Jetta, and it's been using Schaeffer's Supreme 7000 with Napa Gold filters for some time now. He currently has aroun 120,000 miles on the car and it's running fine.
My interpretation of oil "sludging" has to do with an oil's TBN being depleted. In other words, once the TBN goes down to zero, the oil becomes acidic and picks up sludge. This is the way it has been explained in the Toyota sludge problem on their 3.0liter engines a few years ago.
From the UOAs I've seen on Schaeffer's Supreme 7000, keeping a respectable TBN in 5000 miles will not be a problem. And since this oil has excellent wear characteristics, your engine will likely last a lot longer than you want to keep it.

Slalom44, this is the kind of "clarity" I'm talking about. And I don't mean just validating what I'm doing. I'm talking about describing what could be causing the sludging and what in the oil (anyone's oil) needs to be strong enough to address the issue. I appreciate your response and thanks for the help.
Sludge is created by a variety of things...in a 4cyl, heat "cooks" the oil making the sludge/tar. Many times manufacturers design their engines poorly...not providing adequate circulation of the oil in the head which cokes up and gets worse exponentially. Dino oils will obviously coke up much faster than synthetics...Schaeffer's 15w-40 should cover VW specs though...gotta check on that...
502.0 & 505.0 are covered...what specs does VW require on your engine?
