Diesel vs gas

[kayakmike]

The only thing I will add is this is Gen 2 of the EcoD coming out......hoping the complaints you guys have mentioned are corrected in the update.

Note the complaints aren't with the engine. It's the exhaust system that is required to go with the engine to meet EPA/CARB emission standards. Hopefully FCA has learned something from the JGC/1500 f**kup. The exhaust system needs to be tailored to each vehicle anyway due to differences in available space, so regardless it will be a unique exhaust install on the JL/JT (which may be close enough that it's the same for both).

Not to mention that thing is going to be an absolute beast in rock climbing and off road use!

I love the diesel torque in our Jetta TDI, but I only experienced our gas JK (it’s a 2011, before Pentastar) so I don’t known for Wrangler or any other Jeep vehicle. Can someone reports his street and off-road diesel experience?

I'm curious how these drive in normal traffic. I have to really stand on the gas in my JK to take off at a light, if it's up a hill i can watch my MPG drop and listen to the engine whine. I've already made my mind up about Diesel (not interested) but curious nonetheless.

That said, mine has been trouble free at 75k miles, but the added maintenance costs....

Curious what the added maintenance costs are. Things I can think of are DEF and the larger oil capacity ? (I guess, I’m not sure how many quarts it takes). What else?

1. Oil changes - Mopar coupons don’t apply and they charge a premium for the filter
2. Diesel fuel/water separator filter replacement - PITA to replace on your own
3. DEF freezes at 8° thus DEF system issues in cold climates
4. Finding cheap DEF when you need it is a PITA
5. Higher fuel costs vs. actual MPG savings
6. Turbo lag - for best results, better MPG and reduced lag, you really need to swap the PCM

Opposites seem to apply here in Oz, especially since diesel is often cheaper or the same price as petrol.
Huge percentage of new family cars and utes are diesel, some twin cab utes are not offered in petrol at all.
My Isuzu Dmax work Ute averages 8.5 litres per hundred km, maybe 10.5 when towing our camper trailer, so around 26mpg towing. Pretty good!
And the Isuzu does a burn every 500km automatically, it doesn't wait for a sensor to say the dpf needs a burn.
Maybe Jeep have learnt from previous problems and will be more reliable?

The Gladiator will be my retirement tow vehicle. If there are problems appearing, I'll buy a Landcruiser 79 series instead.

I second basically everything @Sorbs said, except for #2. I changed on my own and didn't find it that hard. Also, no experience with #3 in SoCal.

I am personally against extended warranties (https://www.jeepgladiatorforum.com/forum/threads/let’s-talk-ecodiesel.3176/page-7#post-198478). My GC EcoDiesel is the one time I really wished I would have bought the extended warranty. All of the emission system sensors are NOT covered under the emission system warranty. So after 3 years when they start going to s**t, your repair bills will start to rack up quickly. Some of them required the WITECH to reprogram the PCM after swapping sensors since they are tied into the vehicle electronics, so it makes it difficult to do yourself. I had a sensor the dealer was going to charge $1500 for part and labor. Bought , and the dealer will charge an arm and

Same here - waiting here in Oz on the diesel option and any issues and price, if not will be going the 79.

In addition to the def freezing diesel fuel will start to gel at cold temps unless treated or equipped with a fuel tank heater

aww man, what happened at the end? it's like you left us hanging (for Part 2 tomorrow at 9) right at the good part of the afterschool special......

Here when it's winter in the high country they sell alpine diesel. No big deal. Fill up when you get there.

Everyone I know deletes them when factory warranty expires, if they want to keep the vehicle. Takes all those issues out of play

Ha, don't know what happened there. Was going back to look up the info and looks like it only partially saved what I was writing...

Had to replace the upstream NOx sensor. Dealer wanted $1390 ($590 for part, $800 for labor). I bought the part on line for $220 (includes it's own control module). Did the install myself in an hour and found someone with a WITECH who could do the PCM reset for $100. While waiting for the part, the Jeep went into a "vehicle will not start in xxx miles." Started at 200 miles and got close to 0 before I got the part, installed it, and reset the PCM.

I forgot about the NOX sensor. Mine was replaced so extended warranty saved me again!

Funny but did you notice in the diesel settlement that the DEF system and emissions components will be now covered under warranty?

From what I've seen, the extended warranty only covers emission related components (including DEF/SCR). Unclear if it covers emission sensors. I'm guessing not, since the original emission systems warranty specifically excludes sensors. Regardless, the next owner of my GC will get a 4 yr/48k extended emission system warranty.

Warranties don't covers my time of repeated trips to the dealer to try and fix this mess...
