I'd say diesel

But yeah, it's still no diesel.

That does it !
When I get stationed in England, I'm ordering a Jeep /w the Diesel option --
No doubt in my mind !

I would go petrol. Before the knives come out, I've owned diesels. They are great for making big power, as in for towing. People who tow 15 or 18K, do so wiith diesels. You'll see the big 3, GM, Ford, Dodge.
In the old days, a simple mechanical pump pressurized inexpensive injectors, forcing the tip's nozzle to fire (at a relatively low pressure).
Since around 2000, emission requirements have forced engine mnfrs to move to a common rail design. It's a relatively simple operation to understand. Fuel is supplied by a lift pump which typically feeds a high pressure Bosch pump. It's output (5000 psi at idle and 20K+ psi at WOT) feeds a fuel rail (looks like a paper towel tube). This feeds high pressure precision metal fuel lines to electronically fired injectors. The injectors have solenoids that allow them to open and close up to 5 times per cycle
allowing precide fuel delivery.
Now the bad news.
Those injectors run about $500 per cylinder + installation. Water(in diesel fuel) ruins both them and the pump. Manufacturers won't cover water damage, so guess who might replace a fuel system in a 2 yr old car? You can add a water/fuel separator and better filtration, but most people don't. It's not easy to properly diagnose and fix a damaged injector. So shops want to replace the lot.
So what you gain in efficiency might well be paid for the diesel option, higher fuel costs (here in the US), and a 5K bill for fuel system replacement. Not saying they are bad, just pointing out there there is a liability there you don't have with a typical modern gasoline engine.

Which would you prefer, 18mpg or 28mpg?
Would you like torque to climb ascents without needing to change down gears?
It's horse's for course's, I have the 2.8 diesel and I love it. Better fuel economy, more torque and better acceleration for the road. Better pulling power if you tow or drive off road.
Mine cruises at 70mph to 80mph and still returns 28mpg, in UK gallons.

|daggo66||That settles it. No J8 for me!|

I've never driven the diesel, but I've heard good things about it. Certainly more good things than I've heard about the 3.8.
I think it's worth noting however that the J8--which is Jeep's military grade Wrangler (google it)--is offered with either that diesel engine or a Hemi V8. The 3.8 is not an option.

I would give almost anything to have that choice to make.
The diesel would be my choice.

Petrol or Diesel??
I'm just about to buy my first Wrangler. Question I'm pondering is whether to buy the diesel 2.8L or 3.8L Petrol. Every person I've spoken to has another opinion.
Would appreciate some advise from experienced peeps?
