Other then the turbo, better gas mpg and torque? is it more expensive then gas? what about smog, how does it burn? Is it cleaner then gas? |

Plenty of reading out there but for a short answer... +Diesel Fuel is usually cheaper per gallon than gas +Diesels tend to get 24-35% better mpg than thier Regular Gas counterparts +Regular Gas vehicles put out more CO/CO2 and Diesel makes more NOx +With ULSD (Ultra Low Sulphur Diesel), a Jeep Liberty CRD puts out lower "Tons" of byproduct than a Jeep Liberty 3.7L +Because of the difference in MPG between Diesel and Regular Gas...a diesel might actually impact pollutants less than a regualr gas vehicle +Long Term, Diesel Engines tend to last significantly longer than a Gas Engine...so this also creates less waste with a more useful life span +There are many other "pluses" when it comes to diesels ONCE YOU FEEL THE TORQUE>>>you will know why we love them so much |

The main reasons I bought a CRD were 1) needing a vehicle that has decent towing capacity, 4wd, and clearance, 2) fuel efficiency (for environmental reasons, more than economic), and the ability to run bio-diesel. It replaced a 2004 4Runner that was an awesome rig, but struggled to break 20 MPG on the highway. Price-wise, dino diesel is about the same as regular unleaded here in Oregon right now. A couple months ago, though, it was 25 to 30 cents cheaper per gallon. Bio-diesel prices vary widely here, but my last fill up on B20 blend (20% bio, 80% dino) was at $2.87 a gallon. Nearly pure bio from a commercial producer here runs around $3.30 a gallon right now. Oregon just passed a raft of clean energy legislation, and supposedly there is now a modest tax deduction for consumers who buy B20 or greater. Diesel prices tend to increase in the winter when there is more demand for home heating oil (essentially the same thing as diesel). A fringe benefit of running any biodiesel blend is that is provides greater lubrication to the engine than dino diesel, which can somewhat improve efficiency and engine longevity. Downside is that high % blends have less energy content per gallon. Another plus is that bio serves as a bit of a detergent for fuel systems, and keeps gunk from forming (can be bad if running a high % blend for the first time in a rig with many miles of dino diesel on it). Diesel engines tend to burn cleaner than gas in some areas (like CO2, the greenhouse gas that folks worry most about). The trade-off is higher emissions of other pollutants such as soot, sulfur dioxide, and nitrogen oxides. Our CRD's have some emissions control devices on them that are aimed at reducing these (though not the same level of technology as the new diesels coming out of Europe and Japan, such as that 3.0 liter found in the Grand Cherokee CRD). A nice thing about bio is reduced emissions of soot. There have been large, nasty threads here debating diesel and smog. What ever individual folks think, regulatory agencies in the US, Canada, and Europe believe diesel exhaust contributes to urban smog, and have put some pretty harsh requirements on new diesels aimed at addressing it. The other great benefit of diesel engines over gasoline is that due to their relatively low operating RPM's (among other things), they tend to last much, much longer than gas engines. Not uncommon to see Dodge trucks with the 6 cylinder Cummins or old Mercedes w/ 300,000 miles on their diesel with no rebuild, still running strong. Our CRD's are probably capable of similar longevity in the engine, but unfortunately Chrysler cut corners in other areas that may give us problems. Fuel filter and transmissions, for instance. |

Thanks for the factoids. I was talking with a friend about the liberty and said it even came in a diesel version. he asked me what was so great about diesel and I really didn't have an answer other then torque. |

Performance (power per cubic inch) MPG (City and Highway) Towing (Torque and Mileage) Ability to burn alternative Fuels (SVO, BioDiesel, WVO with correct setup) Less Long Term Maintenance (Built stronger and no plugs or wires, ect) Diesel Engines run cooler |

MY simple answer, I like sounding like im driving a tractor every where i go =) My more in-depth comments: Pre 1) BTW diesels do not produce ozone at all, gasers do (pisst, its the spark plugs that cause the ozone) 1)when distilling a barrel of crude oil this is the rough breakdown 60% octane gas 25% centain diesel 15% other kerosine, and many other things. The above is the way the US refineries are tailored. IF you do like europe and maximize output of crude disilleries for diesel you can boost the centain diesel % up to about 40%. Lets not get to bio diesel JUST YET NOW =) Since the barrel of crude is where it ALL comes from, diesel IS NOT more efficent enough by design to make up for the lack of yeild from the crude itself. Conclusion: It would not stand to reason that everyone should run arround driving a diesel as thats not where most of the energy is in a barrel of crude. it is IN FACT mostly in the common octain gas NOT centain diesel. This is why the American market is mostly GAS powered vehicles. trucks typically use up the ofther 25% of the refined crude to haul arround all our crap to us so we can go buy it. This EXACTLY why "the man" is keeping the diesel car market in check because the american crude consumption is ALREADY at a ballance, and should not be disturbed. My 2 cents: I drive a diesel vehicle b/c i like it, for all the reasons mentioned above and many many more. But lets not fool ourselfs... It better serves me, not my country's fuel consumption needs, or the environment OR anything like that. 2)ok biofuels time. Please no one think they will save the enevidable end of the automobile age (which if your under 30 er so WILL be within our lifetime) If you calculate the amount of crop space it takes to create both ethonol, or bio-diesel enough to run our butts all over town, guess what? NOT ENOUGH LAND! and ehhem, oh by the way, all the farmable land for all that nonsense is being used for somthing pretty darn important, OUR FOOD SUPPLY ! The silly legislation on ethonol and bio-diesel forcing farmers to make it is YES jacking up the price of food, go look on google finance, kroger for example, among many other food related industries are going gang busters b/c supply is being limited due to this bio-fuel legislation,, go do a wiki search on bio-diesel, it beaks down how much acrage it takes to create the fuel by type (palm, cotton seed, veggi, ect ect), the math isnt hard to do. There isnt enough land, we ARE screwed! There is one long shot on there about alge bio-fuels backed by Debeers co. in africa, that sounds interesting, lets all hope for the best... If i can figure out how to make a plant in my back yard I WILL!!!!! my 2 cents: I bought a diesel on purpose, b/c when the fuel crunch really gets into full swing, diesel is the market that delievers food and resources to us to keep us alive (it will probably be subsidised so trucks stay on the road delivering food to everyone who cant move anymore), and its a different market w/ different demand than all the other shnooks out there who will be wainting in massive lines to get 5gal rations of fuel at 20 bucks a gallon. Bio-diesel stores well long term, i can stock up, it wont go bad (stocking as oil, converting when needed). I can get it in places most gasser people wouldnt think to look , ill be rollin well after the fall. =) Im doing it for me so "I" will survive, not for mother earth, or father time or any of that horse ka ka, fixing this isnt going to be easy and its not a solution that involves passenger cars like we are used to, go invest in train companies, busses, and mass transit stuff, and try and move close to where you work, unless you work on cars, then i would suggest another profession =) 3) well everything else was pretty well covered in previous posts so i suppose thats all i have to add. |

Going up a steep grade, increasing in speed and the vehicle actually shifts into overdrive to get a lower engine rev rather than automatically downshifting and having the engine scream. ( Read: quieter overall) Being able to step on the "gas" to pass at freeway speeds and having a full range of power band all in the same overdrive gear. (Read: easier to drive without the all or nothing feel to the peddle)  Try one...... you'll see what I mean. I should have converted long ago.

Another, "why diesel". Years ago, when I was young. I was a firefighter in a suburban department outside Cincinnati. All our trucks were diesel. In 1964 the city of Cincinnati came out to see our new 1964 Mack Fire Truck it was the first one in south-west Ohio [so I was told, I was 5 at that time]. They went out and spec'ed all future fire trucks to be diesel. We always bought Mack Fire Apparatus until they stopped building them. When [if you are old enough to remember] there were a lot of ambulances burning up in the '80s because the gassers were underpowered and ran WAY too hot... the answer was to go diesel powered ambulances. Any heavy duty service has diesel powered vehicles. Anyway, every time I got lost or disoriented searching a smoke filled house, I always keyed in on the sound of the diesel engine coming from my fire engine parked in the front of the house. The sound has always meant power and safety to me. If you believe o8K's analysis of the internal combustion engine era, the diesel will still mean power and safety because it is far easier to modify it to run on "different" fuels. Dad |

My opoligies for trying to shorten the story to the point where it doesnt even make sense. THe place was not normal, everyone was just tyring to not die. Yes my prior paragraph completely misrepresents the situation...... |

BY THE WAY if you didnt know, marshall law means you no longer have rights as a citizen of this country in the form your used to, your forcfully protected, which means if you refuse protection, they can kill you! ITs somthing most americans dont really understand b/c it doesnt ever really happen. |

No to get too technical, but diesel engines run hotter. You have to put a lot more energy (heat) into diesel fuel to make it burn than you do gasolene. You also get a lot more energy out of the reaction for a greater period of time and a higher overall # of BTU's. This translates into more work being performed. It is the overall strength and beefyness of a diesel that makes it seem to run cooler. Thicker piston heads, thicker cylinder walls, and larger cooling capacity are all necessary to keep the engine from blowing up. (Just take a look at those old GM 6.2L diesels. They were all built off of gasolene engine blocks and they all blew up at 70,000 miles) Basically, what all this means is that a diesel engine HAS to be bigger, stronger, and run cooler. Otherwise it won't work properly. This is why diesel engines are generally more expensive, but it also makes them able to pull harder and last a lot longer. |

you are misinformed about the 6.2 diesel. Mine would have blown up twice by now according to you. The 6.2 was designed from the ground up as a diesel. You seem to be speaking about the 5.7 that gm built and it was a disaster. The 6.2 and 6.5 are the same basic engine. |
