You explorer guys need to go over to

for all the answers to your exploder problems. To answer the lube question, I have been running Amsoil in everything on my 02 for 262k miles now, still on the original tranny and engine. I have replaced the valve block (at 60k and a known problem) and just replaced the OD servo this past weekend. But I would say it would be hard to go wrong with Amsoil. The best part, UPS will deliver it to your door.

Just a suggestion, but especially if you want a viscosity recommendation, it would be helpful if you can include your location or, alternately, your typical summer + winter temperature plus expected maximum and minimum temperature.

Also, it's helpful if you can describe the service level ... standard or severe service, etc.

Severe service (broadly speaking) is any of:
Dusty environment
Average trip duration under 20 mins or frequent trips of 5 miles/8 km or less
Excessive idling (more than 2 mins routinely or more than 5 mins occasionally)
Towing, hauling

You will get somewhat different definitions of severe service but if you're typically on one side or the other of the above (never/rarely vs occasionally/frequently) that's good enough to help with an oil recommendation.
I am running Mobil 1 0W-30 in both my car and truck. Like so many things, there are more opinions than facts to base them on. Mobil is an American company and the oil is easy to find. Quality as compared to anything else? Anybody really have any good data? With a year interval Blackstone shows sort of high wear metals. Truck get less than 5K a year while the car closer to 20K. I had a NAPA Gold filter. Now running a Pronto.
I have a '99 Land Rover Discovery-1 with 160K miles. I've been religious with maintenance during its life. Couple months ago, I did a head gasket and water pump replacement, and found very clean (for 160K) heads; just a minimal "film" I could clean with a light parts wash. The valve seals were pretty worn out, which I replaced. I've been using Mobil-1 High Mileage (10-30) since it came out. I'm no expert, but the high zinc additive package makes sense to me. I use Baldwin filters, Schaeffer red grease in U-joints and wheel bearings, Schaeffer gear oil in the diffs and tranny. My D-1 runs excellent, FWIW.

Why would you specify a great oil like Schaeffer's and then basically say any filter would do? The oil and the filter are a system so on a $30K plus vehicle why wouldn't you recommend a good oil and the best filter you can get your hands on? A few more bucks every oil change for top rated filter is worth the cost IMHO.
The dispersant packages and the friction modifiers reduce the amount of contamination being filtered.

Filters are manufactured by a couple of companies regardless of the name on the filter. A mid-range priced filter is sufficient to provide good filtration.

Schaeffer does not have an agenda or financial arrangement for filters. Unlike some competitors, Schaeffer warranty doesn't require a specific filter.

My recommendation is stay mid-priced. Schaeffer's prices are below the high end oils, above the low end oils. I recommended applying the same philosophy to the filter.
