Two weeks ago i posted about my truck and the bad fuel mileage at 8.3 mpg now i am getting 7.0 mpg.
I am at the pump every two days and i have more money going to fuel than food heres my last Numbers 137.6 miles= 19.654 gals= $56.19costing me 41.0 cents per mile.
I am so confused about what i should do.
Should i buy a diesel or a gas burner i plan to stay with this next truck along time and i want to get a 20' to 23' enclosed trailer plus i have a 200 gallon tank=to 1600lbs when filled.I will give this info to my creditor so i can plan whats best.
I do need seats enough for 4or 5 people.

just get a 2008 Super Duty Crew (diesel Dually) and you'll sell the bizz before it will crap out on you.

If you are going to be hauling that much weight around and having a decent amount of people in the cab, definatly get a diesel. You will be much happier with the mileage. Gotta ask, why only 7 mpg in a half ton????? That thing should only have like a 350 or so V8. My 2000 2500 with a 6.0 gets 10-12 towing. Have you tuned it up or changed the fuel filter lately?? That will affect your mileage alot.

I have a 1 ton gas that only gets 7 miles to the gallon. I had to get into an arguement wiht the tax person in april about why I need to deduct actual expenses over the 44.5 cents per mile. If i did the mileage deduction I would lose out.

Dang i would love to get 7 or 8 mpg i got a dodge 3/4 8.0 litre v-10 this thing loves the gas. Cost me around 50 cents per mile driven just in gas. I average 5.5 to 6 mpg pulling 6000# 7-8 empty running highway. But hey its paid for i couldnt get anything for it if i was to sell it and its a fairly reliable solid truck i also have another truck for daily driving

so that 7mpg is with the truck all loaded down right? That is still low, I would check tire pressure and air filter. But I'm sure you already did that.

this is a prime example of why one shouldnt buy a 4x4 truck just for towing here in the south. one that note i get a whopping 10mpg from my chevy 2x4 with 350 towing my trailer.

Get a D-Max you will love the torque and MPG.
I have an edge chip in my pick-up and if I can manage to keep it in the mileage tune I get between 18- 23 MPG. But since that truck is VERY rarely used for work somehow it always ends up in level 3-4 tune which produces about an extra 100hp and 250 foot pounds of torque and makes a lot of black smoke:)

What makes you say that? Its pollution. Modifying the pollution output of a vehicle is a federal offense. Infact its a worse offense than opening someone elses mailbox.

People get on here and gripe about everyone competing with them that has no insurance or business license, doenst have this registered, or that commercial tag. Tampering with the emission output devices on motor vehicles is just as serious of an offense.

what are you pulling ? i got a dmax (stock) pulling a 22 foot open tralier 2 72inch exmarks 1 52 inch exmark w/ bagger and 1 push mower and only get 9 3/4 w/ my truck (my p stroke i got about the same) the chip on the ford gave worse milage (maybe my foot had something to do with it) but is the chip what helped your truck so much or maybe the amout of weigh i am pulling?

its not pollution...only gas engines are pollution! If it was a serious offense, it would be illegal, its not. black smoke dont hurt the air. It makes the air beautiful!! seein a duramax, powerstroke, or cummins takin off with a big ol cloud of black smoke is a beautiful sight!!!

Having a truck chipped and blowing black smoke is not illegal. Now modifying the cat and egr, thats a different story.

Something does sound wrong with your truck tho. My 05 Z71 averages 16mpg. That is half loaded, half unloaded. Fully loaded my truck/trailer weighs 9-10K and I am getting about 10-12MPG.

If your looking for a new diesel I'd highly recommend the Duramax. That will be without a doubt the next truck I purchase. GM seems to be having very good luck with all the emissions stuff that are on the trucks now (unlike Fords new flamethrower) and are averaging 20 MPG empty

Black smoke is good, white smoke is bad.

So do you run Bio Willy fuel in your diesel? Or used, filtered oil from resturants blended with your diesel? That is more environmentally friendly and is recycling.

Black smoke is just as bad. I do not use biodiesel yet, but i do recycle used motor oil in my waste oil heater in my shop.

Oh yeah and federal law states that any modifications to an emission system that changes output, including but not limited to exhaust, gear ratios, vacuum system, tire size and computer control you have broken a federal emission law.

Any modification that is not produced by the manufacturer of the automobile is for off road use only. Check the stamping inside those big fancy rims people like.

Federal emissions testing is coming nation wide in mid 2008.


And it is illegal joshc, how bout next time you eat at a restaurant I come fart in your dinner and see how you like it so try to keep my air cleaner.

On my Honda......I removed the cat and replaced it with a straight pipe and fooled the o2 sensor to gain more top end power. I live in an area that requires emissions but that is only every two years. Prior to the test I jack up the car and switch out for the cat and go get my test. Illegal? Sure, but when I get pulled over they're not going to give me an emissions check on the side of the road.

CA is a pain to live in. They are now destroying cars for any modification. I saw video of an awsome car destroyed......didn't even auction or part it out.

All in all, people modify their vehicles and some things may be illegal. We are a country of great wealth and waste but at least we have the EPA to bust balls on industry......China is a real problem, not our black smoke from less then 1% of modified cars on the road. After all, as an industry we could be using electic or propane mowers right?

Like I said before everybody gets on here and screams about the guy working with no licenses or insurance. So what makes you so special you get to break the law? Either be a law abiding citizen or shut up. Bottom line. Dont get mad about your competition breaking the law when you are doing so yourself.

Thats called hypocrisy.

Read about that black smoke coming from a diesel.

A correctly running diesel engine should not emit black smoke.

KTO, are you serious? Last I checked, pulling truck/tractors, and drag racing trucks spew out tons of black smoke, and they're the most properly running diesels there are, last I checked. I don't know where you get this off road use only stuff. If rims where not street legal, your local shop would not be allowed to legally install them. Chips are only illegal if they emit more pollutants than a set standard, I have yet to see one that is not at least 49 state legal. As mentioned before, Cat. Converter, and EGR modifications ARE ILLEGAL. Tires, wheels, tuners, chips, and other stuff of the sort are NOT ILLEGAL. Diesels actually pollute less than gassers, but you can see more of the less harmful diesel emissions. Don't worry, if you want to spew black smoke, be my guest to come do it in my front yard, my back yard, my living room, my bedroom, anywhere, I don't care, you ain't hurting my air, instead, you are providing more entertainment for me.

KTO, if you would like some further reading on the diesel community, head on over to http://dieselplace.com/forum/index.php . It is a mostly GM diesel based website, but you will find tons of info. I believe their are approximately 50,000 members, each with information to contribute. Member experience ranges from the weekend joyrider, to people that are on the cutting edge of diesel engine technology.

I guess KTO has never pulled anything with his diesel. When you hook a load to one they tend to burn black. My duramax smoked pulling when it was stock which is perfectly normal. I love putting the edge on level 5 and filling a lane with smoke. All the while getting better fuel mileage than KTO's vehicles. Who's wasting more fuel?

Right here in josh c's own forum it tells about how a diesel is only as efficient as its driver. More black smoke equals less fuel mileage!

Black smoke is caused by fuel being burned. What do you not get about that?
The more black smoke the more fuel being wasted

So unless there is black smoke pouring out of your tailpipe, your engine is running "almost as efficently as physically possible". Straight from a post by Duratothemax

Diesel engines produce very little carbon monoxide as they burn the fuel in excess air even at full load, at which point the quantity of fuel injected per cycle is still about 50% lean of stoichiometric. However, they can produce black soot (or more specifically diesel particulate matter) from their exhaust, which consists of unburned carbon compounds. This is often caused by worn injectors, which do not atomize the fuel sufficiently, or a faulty engine management system which allows more fuel to be injected than can be burned completely in the available time.

The full load limit of a diesel engine in normal service is defined by the "black smoke limit", beyond which point the fuel cannot be completely combusted; as the "black smoke limit" is still considerably lean of stoichiometric it is possible to obtain more power by exceeding it, but the resultant inefficient combustion means that the extra power comes at the price of reduced combustion efficiency, high fuel consumption and dense clouds of smoke, so this is only done in specialised applications (such as tractor pulling) where these disadvantages are of little concern.

KTO, I find your arguments about diesel a bit off track. This is coming from someone who drives a race car. You would not be running racing fuel in that car would you. Talk about polution, I can recall the days sitting at the tracks and if those are clean machines I am Batman.........

KTO, BTW not trying to bash you at all have enjoyed your post.

I do run racing fuel, and believe it or not, it probably burns cleaner than most cars from the factory. For one racing fuel is a very clean burning fuel. At around 98 octane for sunoco purple, it is quite cleaner than any fuel in street vehicles. Local divisions have been on unleaded for many years
It burns a whole lot hotter than than regular fuel and we run the engines so lean that the exhaust pipe is completely gray where it comes out the door.

And believe it or not i am a firm supporter in diesel vehicles. Problem is americans wont embrace them because diesels have a "dirty" stereotype. Also american mechanics seem to have a hard time properly understanding diesel engines

bahamamills

Thanks for the reply I can see where the racing fuel should burn cleaner wow what a smell.

In Europe, the majority of cars have been diesel for years. I recall maybe five years ago picking up a Ford Tarus 5speed rental car and thought when I started it the motor was blown,,,,,,, it was a diesel.

JoshC
08-14-2007, 12:19 PM
What many people misunderstand, is although the black smoke from a diesel is VERY visable, it pollutes less than gas. One thing that upsets me, is the strict emissions requirements that will be put in place in 2010. The requirements now, with the Diesel Particulate Filters is turning out to be pretty good without many major problems. But in 2010, the engines will basically be required to have their exhaust gases cleaner than the air that they are intaking. Now thats the EPA at work for ya.

KTO, I am sorry for calling you names and being rude to you. To everyone, I am sorry I took it too far, and apoloqize. Mods, thank you for leaving my posting rights so I can redeem myself. I just get very upset when I see false information about diesels. Diesels are probably the cleanest vehicles around. As far as tuners go, they are not illegal, and do very little damage to the engine. Don't get me wrong, they do hurt the engine, as any horsepower increase does, but it is almost un-noticable.

I would like to publically appologize to anyone, especially KTO, that I may have attacked or offended by my posts on this topic. I am a stubborn young adult and sometimes do not know when to let things go. Although there are somethings that go on on this site that I don't agree with, I realize there is a vast amount of information that I can learn from. Again, I hope there are no hard feelings and that you will accept my appologies.

Looks like DieselOnly beat me to the appologies.

People (me) sometimes do very stupid things to win very stupid arguments over very stupid topics. Once again, sorry about last night, I got a little carried away, no hard feelings. We'll just forget about last night, and continue with our lives?
