One day youll get OLD and slow down like the rest of us. :dead:

At about what speed do you travel to get 38 MPG? What transmission tune do you have? Finally someone drives these CRD's at a reasonable speed.

Just because it has a 5 speed that shifts in about 65 doesn't mean that you must drive it 70-80mph.

I like driving mine as slow as it will go in 5th locked with the RAM Hemi TCU.

Yes, I know some people will say that I'm lugging the engine, but most diesels get the best MPG between 13K-16K RPM. Some even have a green area on the RPM gauge like the old Mercedes 1319 trucks. I have also read that you need to be at or below 1100 RPM's to really lug a diesel.

He drive like 50mph on the interstate with his mirrors folded in,one is illegal and the other is more dangerous then speeding/driving aggresivly.

And how do you know this?? You live in CO and he is in WA. You are no where near him. I don't believe you could know exactly how he is driving. Even if he does drive without mirrors extended, I don't believe that amount of wind would rise his mileage much if any at that speed with the mirrors turned in.

Most of my highway driving is in 55 MPH city zones, and when traffic & time will allow I commonly drive 50 MPH in these areas. Why spend the extra money on more speed when it is not needed??? Yes, I stay out of the left lane. Some of us would rather save money on fuel then to throw it away just to drive like everyone else on the road who could care less about there MPG and wouldn't really know how to hyper mile if they even tried. 90% of America doesn't truely care about how much money they spend on fuel just as long as they can drive as fast as everyone else does. Although they will complain like crazy when there pay check runs out before there next one arrives.

In most states it is still legal to drive 45 on the highway, and many trucks don't travel over 65 and some as low as 58 on flat land in order to achieve better MPG (of course they all slow down going up large hills and mountains). Trucking companies have figured it is better to slow down then to run 70 or what ever the speed limit is. It cost them big money in extra fuel cost to run 70 on the highway and the time saved doesn't equal more revenue compared to the extra fuel cost. So they program there engines to run slower to save the fuel and extend the life of the engine (less fuel usually means lower EGT and longer turbo life) and less wear and tear on other components.

He's stated his driving habits plenty on this forum.Going 5-10mph below the speed limit is one thing but 20+ is just asking to cause a accident,more so when most of those types only drive in the left lane.I don't know where your from but back home(not CO) if your doing the speed limit on the interstate your going to get past like your standing still by fully loaded semi's.

Before my SFA swap I got my best mpg's at 78mph,any lower and the trans would hunt bogging the engine down and dropping mpg's to around 15-16mpg but at 78mph no gear hunting and would get 21.9mpg's(at 2900rpm's).Same trans as you CRD's have just without the programing for the 2nd OD(45RFE).And that was with 32" tires and weighing 5500lbs here in CO,that 21.9mpg was saw goming back from MOAB to Colorado Springs,not a flat drive.Granted now with SFA and 35" tires and 5.13 gears I'm gear limited for speed but generally stay right at 69-70mph which is 2900-3000 rpm's and can still get 18mpg's out my 6000lbs+ pig.

Yes I track my mpg's very closely but don't care about the actual #'s.MPG's is a good way to spot early signs of problems before they actually become a issue.

Lol, TJ2, that was funny. Seriously though, Al Gore with his tree hugger politicians and all the stupid nonsense about global warming created this EPA draconian pollution norms we have right now. Nothing against Al Gore from my side, but this global warming hysteria is why we have EGR in our diesels. If one as a politician does care about pollution, just make all diesel b20+ and here you go, less pollution.

Regarding guns, I think Hexus meant he will keep his tune regardless of EPA norms, even if it would be against the EPA, which I one agree with.

Lol. CRDJoe must be a very patient man. I couldn't drive that slow even for 50mpg... but hey, if it pays off for him, that's all that matters.

CRD Joe · **Posted:** Fri Sep 13, 2013 3:32 am

I can speak for myself wise guy. I drive 58mph with my mirrors turned in. I drove to Phoenix from Seattle this spring. On one tank while driving the length of Nevada I got 39.80 mpg. That's the best Ive ever gotten.

I have an Inmotion chip with a trans tune from our friends at GDE.

Glend · **Posted:** Fri Sep 13, 2013 5:06 am

I drive slow as well but more by the EGT gauge then the speed. I try to keep pre-turbo EGT to a limit of 1000F, if it heads above that I back off or force it into a lower gear. I see this as the best way to insure that the engine lasts a long time, and I also translates to very good fuel economy. BTW VM has a graph that shows the best fuel volumetric efficency is at 2000rpm, but there are other factors like load, terrain, gear used, etc.

well, at least Now I feel much better about my 38mpg max hwy, and 20mpg city...
( I tend to target 1,900 rpm - on mine 2,000 rpm = 68mph )

Maybe I'll go for that transmission tune as well after all..

:JEEPIN:

I'm with you on increasing use of biodiesel (and before some clown claims that veggie-oil IS biodiesel - no, it isn't. It is feedstock to make biodiesel. I used to work in a biodiesel plant, doing production.)

The issue is that, on the whole, boosting biodiesel production to even being 1% of the fuel supply would take a tremendous increase in biodiesel refining capability. Here in RI, the state was proposing moving to a 2% mandate. The company I worked for was actually against it, despite being the only major producer in the state. The % mandates end up in manufacturing of sub-standard biodiesel by less knowledgable producers. Diesels are good, but running bio with too much glycerin totally fraks up a diesel real quick. The ASTM standard for biodiesel is actually challening (we were using recovered veggie oil from restuarants to make our biodiesel. This method results in a net reduction of CO2 by 85% compared to ULSD).

Isn't the reason Daimler-Chrysler gave up on the CRD, was the emission requirements were too much?

The ERG was a band-aid solution to quell some of the EPA issues. Hasn't the bluetec become the current solution for many diesels now?

With these regulations come new designs. The new designs advance the technologies and if everyone played by the same rules then competition for your business will be based on your needs. "Clean" diesel isn't necessarily compromising performance is it? :2cents:

Yep. They stopped due to EPA requirements. But yet they still put the CRD engine in pretty much all the other Chrysler products in Europe and Australian markets. Heck, you could get it in the Town and Country. Stinking Gooberment.

Leave it to tjkj to come along and try and rub salt into our wounds, as if any thing else is new? LOL

Fun to have him around. :jester:

I like to use http://americanfreedombiodiesel.com

It's 'virgin' soy oil. It's close to the peanut oil the original compression ignition engine was designed to run.

It may be politically correct to call an arse hole a hemorrhoid, but it's not quite the same.

Bio-fuels are just a small fraction of the 'solution' for future energy demands. The solution will be a multiplicity of all available technologies.

For those who deny global warning. I humbly implore you to write a letter of 'declaration of beliefs' and leave it you to grand kids. They, after all, will judge your (our) behavior.

the emission test can't reveal if the egr working or not ,if you pay attention, during the test, emissions are controlled with the engine idling and during kick-down, in this case the egr is not active , the test control only the CO emission and cant' misure the PM10 .or NOx ....but

rumors, saying that the centers of emission control, are gearing up to check whether the emissions systems work properly , Unfortunately, it is known that such systems are disabled

Dear Grandchildren,

We know that climate change has been going on for billions of years, I am sorry fat Al Gore is profiting from this, in his high carbon producing mansion, before you earn your first dollar you will be in debt. I hope they do not blame your car if we get another ice age in your time. And BTW the military industrial complex is exempt at your expense.

Love Grandpa

Thanks pops,

Please ask Al Gore to leave us some thick Columbia jackets for the "global warming" that's gonna kill us all... lol.

You know, whatever happens, its because global warming... even if its an ice age. But quite honestly, I have to give Mr Gore credits for being a smart guy to contribute to a scheme that makes money out of nothing... er... thin air... er... carbon...

Overall, politics and politicians suck! Better go back to our crds till global warming won't kill us all...

TJKJ is just frustrated at his CRAPPY mileage. Ive been driving on interstate 90 140 miles from Eastern Washington to Seattle twice a week for the last four months and MOST of the big rig traffic stays in the right lane and drives 55mpg! They NEED the better mileage because of the cost of fuel! Im not endangering anyone.
