That's what I was thinking based on the chart. Thanks, Spike!

Lets face it, LR engines aren't exactly precision technology...they run hot and are dirty.

Rotella is really some of the best oil on the market today.
I'm hoping I can push my engine for several more years by switching to this stuff.

Advantahe of the diesel rated oils is that they are formulated to deal with soot blow by, which will turn fresh oil in a diesel very dark very quick. The oil keeps this in suspension, so the filter can catch it. Old style conventional oil basically lets it settle out the bottom (sludge). And the diesel oil has more "cleaners" in it. I run Rotella in lots of things, high miles personal vehicles, and heavy equipment at the office. My favorite fork lift lives outdoors, has a big John Deere turbo charged diesel, and a 30 quart oil pan full of Rotella 5W40.

Ahh...that raises another question.

Does using Rotella or Royal Purple require a different filter?

I use a WIX filter (forget the number) on my truck.

Why would you think using a different filter would be required for a different oil?
Motor oil does not know what kind of oil you are using.
I also use Wix oil filters.

Also you cannot judge how "worn out" oil is by the color of it.
All oil suspends contaminates, sludge is formed by the additives breaking down.
The base stock in a oil never goes bad, it is the additives that go bad and break down, when they do they form sludge.
Using the wrong oil for the application is the number one cause for engine sludge.
Going to long on oil changes is number two.

Better to ask the question than find out later that I needed a different filter to handle a thicker/specially formulated oil.

I am a software engineer, not a chemical engineer or auto mechanic by trade, so I like to make sure I ask enough questions to help educate myself on the subject before making a stupid mistake.

The only stupid question is the one not asked.

On a side note, have you explored any stretch of the Washington back road discovery route?

WABDR - Washington Backcountry Discovery Route

I have a sabbatical next summer and I have a rough plan to take a couple buddies with me and the Rover and run at least half of it.

Cheers!

that looks awesome!

i havent really had the rover that long but am definitely looking for interesting places to take it/go camping this summer
