#484 of 570 Can anyone figure by marsha7 Dec 11, 2006 (5:35 pm)
why the diesel in the MB E320 gets in the 30-plus mpg highway, yet the diesel in the upcoming 2007 Jeep GC only gets around 19 city/23 highway, only 2-3 mpg over the gas engine///...is this worth bragging about, or am I missing something???...can't Jeep/DC do better???

Replying to: marsha7 (Dec 11, 2006 5:35 pm) I know that the drag coefficient on my 2004 Jeep Wrangler is a bit more than twice the drag cooefficient on my 2006 E class CDI, and that the flat plate area ( or frontal area ) of the Wrangler is significantly higher than the E class. Add those two factors up and its safe to say that my jeep at 60 mph has more than twice the drag of the MB diesel.   Same reasoning applies to the GC, although I'd estimate that the drag coefficient isn't as high as the Wrangler.   There are other factors involved as well, but the drag is a major factor.
#486 of 570 Biodiesel in MB by greasykid1 Dec 14, 2006 (4:50 pm)
From what I have read no more than 5% biodiesel is permitted in current diesels.   Read some older posts and you will find people who had severe damage that is not warrantied by MB.   You can always contact MBUSA.

Replying to: blissful (Apr 02, 2006 5:39 pm) >What is the "RPF filter"? Is this an add-on, or something that the newer diesels have from the factory? Mine was built in late 2005 (model year 2006).   Hello   Sorry, this was a misprint. I meant DPF = Diesel Particulate Filter. This filter prevents Diesel soot from getting out and burn them in regular cycles (every 1000 miles for instance). This technique was pioneered by Peugeot in Europe and is very widespread there with new vehicules now.   Old DPF required regular maintenance, which periods extended gradually with the help of new technology. I heard that current DPF are "maintenance free"   I don't think DPF could be installed as aftermarket, although this would be a sensible offer Replies to this message: vchiu (Feb 05, 2007 3:46 am) blissful (Feb 10, 2007 12:52 pm)
#490 of 570 Re: B100 -> voided warranty -> oh well !? [bduser] by vchiu Feb 05, 2007 (3:21 am)
Replying to: bduser (Jun 20, 2006 10:17 am) >... Nowhere on its website does MB say that the use of BD is prohibited. Nor do they tell their dealers to inform customers that BD will invalidate the warranty. This is willful deception. They believe there is a problem with BD, but won't tell anyone, and won't make the information public.   I think you got a case for a legal action against both your dealer and MB.   1) Lack of Contradictory written information regarding B100 2) Absence of proper documentation when taking possession of the car 3) You clearly indicated your dealer you intended to use Biodiesel and he did not objected in any way.

Replying to: vchiu (Feb 05, 2007 3:03 am) Now I remember   RPF stands for te German word RussPartikelFilter. that is the German Acronym of DPF.   DPF should be mandatory for all diesels including trucks. they drastically reduce soot Replies to this message: blissful (Feb 10, 2007 12:52 pm)
#492 of 570 320 Bluetec VS Toyota Camry Hybrid by vchiu Feb 05, 2007 (3:55 am)
I would be curious to see a real world MPG comparison between both.   It seems the car develop nearly the same HP and are of similar size and weight. How about performance wise as well?   Well, I know that the MB is maybe twice the price of the Toyota, So this can't be taken into consideration.   Waiting for an Edmunds Comparison test with anticipation

Replying to: vchiu (Feb 05, 2007 3:46 am) Thanks! I still have only about 6600 miles on it, and it has not seemed to be as noticeable as it was after that one trip. Perhaps part of the "burn in" or breaking-in of the engine allows more soot. Or, maybe it was sticking more due to weather conditions. Also, since then I have polished the car, and perhaps a slicker finish has made the paint surface less "sticky' for the diesel particulates. J
