Thats what I'm getting with a 300tdi in a 130 on 33's. I'd be happy with that milage-as diesel climbs up over $4 you can always drive easier and increase your milage-I can't.

I get 19-20 mixed town and freeway, but that's with a built rig and a 300tdi. (D1).
My RRC could get 27 on the flat on the freeway at a steady 65mph. The guy that bought it got 24 going home with a 45 mph head wind at 75 mph. That's pretty good.
I love the 300tdi. However, it's damned expensive. If I were to start over again knowing what I know now, I would do a 6.2. I had a CUCV blazer I bought from DRMO a few years ago. It was a great rig. I loved the power. Drove great. Good mileage. My blazer was very reliable. Cheap to buy and operate.
Well, let's compare costs...
$895 for a used 6.2 long block. $1095 fully dressed. $1995 for a dressed rebuilt. Is that right?
Then, you need the Mark's Adaptors kit, right? Does that kit work with the 300tdi bellhousing for the R380, or the the bellhousing for the V8? Ditto on the flywheel and clutch, V8 or tdi?
Then looking here:
http://www.landroverimport.com/products.html
$3800 for a used 300tdi, or $5800 for a fully dressed rebuilt. Also includes radiator. In my case, I'd need a used R380 bellhousing, a flywheel, and a new clutch kit.
The legality of 300tdi's in the US is irrelevant to me.
How built is your truck? What is making it use that much extra fuel? Is your EGR blanked off?

yep, love this thread. I stay awake at night dreaming of putting a diesel in my DII one day and I think the 6.2L may be the way to go for the aforementioned reasons.
RovingBeetle from Discoweb/pirate4x4 did a very, very expensive Isuzu 4bts swap in a 2000 DII. I test drove it while RedMountainRovers a.k.a RMR4x4.com had it on their lot a few years ago. Totally fell in love with the truck. Total Mad Max vehicle. Funny thing is, I ended up with the same year/color truck.
here's the youtube, enjoy!

Update on the 6.2L Disco:
Crossing 4k miles on my ownership period.
Alternator belt failed, but found out that v-belt sizes on this motor are a subject of controversy and can lead you astray. Found the correct belt for my application and no issues since. PM me if you want a no-**** alternator belt part # for a milspec 6.2. That extra 1/16th of an inch diameter makes all the difference...
Sitting solidly between 15-18 mpg city, depending on my foot.
Other than the one alternator belt change, nothing else to report. Still doesn't leak a DROP of oil. The 5-speed R380 works perfectly. No problems with the home-made (well, professional BMW shop-made) dual-battery and cooling setup.
I've just been driving the piss out of this thing. Totally turn-key, every time for 4k city miles in sweaty Savannah, GA.
This is a good setup for those considering. :smiley_drive:

Just a quick comment on that:
Diesel right now around here is between $4.09 - $4.39/gallon.
I'm barely coming out ahead -- if at all -- in a cost-per-mile scenario. I think over the long run, including regular maintenance schedules, etc., this motor will prove more robust and durable... but don't forget about the cost of diesel when you consider this conversion (if you're going for pure MPGs.)

That's the key point when considering diesel conversions. You will never get the money back on the conversion via fuel efficiency, and I seriously doubt it if you add improved reliability. These conversions are purely for the sake of doing it and coolness factor. There isnt any economical advantage. Keep your gassers and keep them in good working order. Its still cheaper to replace an engine than it is a new (or newer used) car. Just my opinion. I still enjoy reading these threads and the tech involved in the conversions. Good stuff

The advantage I like to think about is the extra range you can get switching over to a diesel engine. I like the thought of filling up once instead or 2-3 times to get home.

there is no miracle cure for mpg but if you make your bio diesel it is an alternative and you save a lot .

Going diesel you get to lose all the problematic electrics associated with the gaser.
Just for comparisons, here in SC Diesel is $3.85-$3.95 but it wont be long before its over 4.
I'm getting a solid 22-23 mpg, 450 miles to a tank with my 99 SD D1 (300tdi)

Yeah, I can't quite get 450... but hitting that 400 mile mark with the kind of RPMs (i.e. "mixed" driving) you'd expect in expo-style conditions is nice. It's hard to go 400 miles without seeing any fuel in the U.S. unless you really design your trip that way.
I remember the 220-mile gas warning light with my 3.9 Disco... :Wow1:
Got a big trip to the southwest planned this summer... we'll see how she does in the heat and at altitude.

It depends where you live. Diesel and Gasoline average the same price here. Diesel is higher in the winter and Gas is higher in the summer.
Let's see Georgia...http://www.georgiagasprices.com/
Diesel $3.80 to $3.90
RUG $3.45 to $3.60
Alberta...http://www.albertagasprices.com/
$3.70 to $3.80 for both RUG or Diesel. Wow, I thought fuel was always cheaper in the US.
