Re: Is the diesel really worth it????

I used B100 for about 80k miles in my TDI. Not a single problem. I *would not* use it in my BMW 335d.

Diesel engines in theory are a great idea, but all these emission controls make the engines very expensive to buy and to maintain/fix.
I don't understand the issue. Who cares if the DPF stops working? It won't affect performance only emmissions. I'm not loosing sleep over that.

At 700 miles per tank... Hell yeah it's worth it!

But if it stops working won't it get plugged at very least causing a code and very likely causing loss of performance and possibly damage ? I understand that it can be run without the system but that results in copious amounts of black smoke coming out the tail pipe (not restricting flow) I'm not an oil burner expert by any means so I could be wrong but physics doesn't change with a change in fuel.

That is a big part of the misconception about Diesel engines here in the U.S. A properly tuned and operating Diesel engine doesn't blow copious amounts of black smoke, DPF or not. Dudes with bro trucks with 22" wheels, smoke stacks, and "coal rolling" tunes, and improperly running diesels blow copious amounts of black smoke.

Trust me I want the diesel and I'd love to be able to run biodiesel in it (i live in MN and this state is pushing that stuff hard, its just a matter of time until they mandate a minimum percentage of all fuel sold being biodiesel just like they did e85) I just don't understand what the purpose of the dpf is if not removing the crap that burns creating black smoke...like I said I'm not a diesel expert but I have to believe it serves some purpose. If you say it won't hurt anything other than the pocketbook should you get caught running without it I'm not going to argue as I assume you know what you are talking about. That being said you do say a properly tuned diesel which brings up this...isn't the engine tuned to run with the dpf functioning normally? Is it not part of the exhaust system (I truly don't know I'm asking) ? If it were plugged isn't that a restriction on the system? I can understand it running just fine when removed and pcm modified to compensate for its absence but I have a hard time believing it could just be left alone without causing problems...but then again

Re: Is the diesel really worth it????

The CRD Grand Cherokee has been running without isues here in Australia for 2 years now. I have not heard of any major issues with the injectors, DPF, or it's reliability. One owner reported an issue with a shigh pressure injector, but that is all I have heard.
The engine runs smooth, is as quiet as a mouse when cruising, and will pull like crazy.
If you want the thrill of a V8, there are after ECU mods you can plugin to get that extra performance.
The best recommendation I can make, is wait until it is released, and go drive it. Compared to the V6 petrol engine, there is no competition. The diesel wins hands down every time. After you drive 700 Mls between fuel stops, you will have a grin from ear to ear. Our experience has been gained with the 5 speed. It will be much better with the 8 speed.

Re: Is the diesel really worth it????

VW diesels have been running without problem in Europe as well. However the VW's, along with chevy and ford trucks which all use Bosch fuel pumps have been having catastrophic failures of the fuel pump necessitating expensive repairs. The thought is that US diesel fuel has low lubricity which is causing these failures. I recall reading somewhere that the Jeep engine uses bosch fuel pumps, but am not 100% sure on this.

Re: Is the diesel really worth it????

I saw diesel at the same price as regular in los Angeles today - $4.20. later in the day, I saw a station with biodiesel at $4.29 and regular at $4.19. I've been averaging 22,500 miles per year, so it would definitely pay-off for me. If regular and disel stay the same, the break-even point would occur much sooner.

When you live somewhere that you cannot get anything other than bio blends then what ?
