My 2007.5 6.7l

Ok with all this talk of "cant do this" & "cant do that" I more or less just don't take much said on this site to heart cause I have learned over the years that people are generally stupid. Not saying her, but people in general. They don't know what the heck they are talking about 75% of the time so why talk? I just hate hearing all the BS... I for the life of me can't see why somebody would just say something they don't really know is true just to get a post count on a online forum.. Thats how people end up getting screwed cause they listen to some kid say what his buddys dad ex father inlaws grandpa used to do, lol.... If you personally don't know, don't say anything.....
END RANT..................

Ok, ok sorry for that it just gets old to hear stupidity constantly on these forums...


Ok my '07.5 6.7l is bone stock, 30k miles and has had two oil changes, one air filter change and has been reflashed one tim (BA I think?) and it just amaizes me how much Dodge says you have to do to maintain these trucks.. Why? I honestly feel that Dodge makes phony "maintanence" books so that people just spend money for nothing and end up at the stealership buying dumb crap or having un necissary work done. Why? Is that really a good way to keep people loyal? I can't stand a crook and it seems thats all Dodge is, they try to rip you for everything they sell or offer... Hell, I am not paying some of these prices for stuff they say you have to buy and change... Maybe it's just me but, my truck gets over 20mpg on the highway and I have a stock fuel filter at 30k miles, so why should I be on my 3rd filter??? Hell, I just the other day drained the damn "water" which it had zero water, so why exactle are you guys swaping filters at 10k? Cause a book says so?? lol.... I mean don't get me wrong hell, Im all about mainanence but I am also pro-saving my damn money. Especially these days....
I also don't get this rearend fluid change every 10k miles or whatever it is... Why do we need to change fluid that often? If im 100% wrong please explain I never claimed to know it all but it seems to be a damn waste of my hard earned money....
So I figured by "Dodge" standards im ruining my truck so I did some testing.....

I pulled my MAP sensor and it looked new... Thats 30k miles, hwy and stop and go...I even let it idle I had maybe MAYBE a tissue thickness of light soot but I could see threw it fine and no buildup what so ever. Hell, I didn't even need to clean it but I allready removed it so why not right? So I spray it down with good ol' brake cleaner..That stuff Dodge says will ruin it, lol... Grease the o-ring and slap it back in. Noticed zero mpg change.

I also run the factory EGR in working as supposed to fasion, not unplugged so I can boost my mpg by basically lowering HP/TQ lol... I have no stupid issues and have only been at "80% catalist full" two times in that 30k miles. For a year I lived 5 miles from work and went to lunch at noon everyday.. Do the math on that terrible stop and go time.. I also started and stoped it in drive threws and anytime I stoped at a fuel station ect... No problems what so ever... I got that message twice and both times didnt pay it any attention after I knew what it ment. It just went away by itself.. I have had a engine light come on and looked on here saw it was anothe Dodge BS reason so I ignored it and it went away. That light has come on and off about 20 times in my 30k miles and I havent changed/fixed/cleaned a damn thing any of the times and it went away all by itself... So why do I need to have my turbo tapped and cleaned?? lol.... Cause Dodge say I do... Why? I didnt and my truck still runs like the day I bought it... I just am growing to think that Dodge is full of it and basically just want to scare people into coming to their wolf den to get ripped off... I was told by our tech he's a late 50's been in the oilfield his whole life, no diesel mechanic degree BS just a guy that learns the ol fasion way..... DO IT.... He basically said run the damn truck till it breaks, fix it and continue on your ways.... I have taken his advise and havent had a single damn thing go wrong with my rig yet, not a single time when that stupid light came on did I go to Dodge and beg them to steal my money cause their pimple faced 18 year old "service tech" said my turbo needs cleaned and its gona take them three days blablabla no, I ran the code saw it was BS and erased it only to see that it never comes back, lol... It takes awhile and then 5k+ later bang back on.... Hmmmmm, seems to me that Dodge just programs codes to pop up anytime they figure somebodys dumb enough to just let them say anything to take your money...
Im 28 and don't know it all... But I do know a theif when I see one and Dodge is a theif.. I don't do 1/8th the BS they say and my truck runs like new, I may be just horribly ruining my truck mile at a time, lol but im sorry im not gona crack the window and just throw 1$ at a time my hard eraned money out the window.
I have been driving big trucks for almost 8 years (legally ) and grew up in a dirt racing family that goes back to the start, converted to drag racing in highschool and been doing that ever since. Im not dumb, arrogant or smartazzed but, I do know my way around a motor and it seems like Dodge doesnt have a damn clue... I just wanted to kinda rant a little mods can delete this or yall can all tell me im stipud and dont know left from right but, I just wanted to BS a little cause im bored and im off tomorrow so I am looking around online and had to vent...

Please all comments are welcome good or bad cause when the dust settles I wont ever meet 98% of you guys so in all honesty it dont matter what you feel about me, I will live and you will live and the sun will rise tomorrow either way.

Thanks for your ear
Joshua Lee

At a Dodge service department you will find the best service managers and technicians on the planet You should never question them... You also never need to change the fuel filter, ever! when your at the station just watch for crap coming out of the nozzle If you cant see it, its not there. And if your differential doesn't have a drain plug the fluid never needs changed. Thats why it doesn't have a plug The overhead mpg meter are always spot on, its the people who lie.


does this count for a post?

I agree one hundred percent. I recently had to take mine in to have the ac charged because you cannot jump the compressor on to fill er up with freon. THEY have to do it via computer... thats dumb. If I could sell my truck for a decent Price (I hate to say this) but i think I would buy a ford because they back their trucks and dont fix it if it aint broke!!!

his point is that dodge rapes everyone with their service interval.

i dont let the service department do diddly-squat to my truck except change the oil (i have lifetime oil changes) i let them know that i don't even want them adding window washer fluid. the more crap they put on a truck the more crap can go wrong. they're always trying to squeeze every dollar out of you

Diesel fuel in the US has historically been very dirty and often filled with water, partially why they recommend so often fuel filter changes. The common rail injection systems are also more fragile in terms of fuel contamination and fuel flow.

You honestly sound like you have no idea what you're talking about. Its quite evident you barely have a grasp on how electronic fuel injection systems work. Its quite evident you don't understand codes and what they mean (just calling them "BS"), you don't understand that the computer reacts to current conditions. Something like a VGT actuator can get stuck for a few days, then eventually work free, possibly throwing a code, and it never coming back.

It sounds like you barely read things too, changing differential fluid every 10k "or whatever" in your words. No. Most people (and manuals) recommend changing the differential oil within the first few thousand or so miles, because as the gears initially break in and wear too each other, a lot of metal filings get dumped into the oil, and do you really want abrasive metal spinning around in your gears and bearings?

I don't see you as a smart or dumb, but you are arrogant. You think just because you grew up with a gear head family, that some old guy who "learns the old fashioned way" reaffirms what you think, and that you've been driving "big trucks" for 8 years (sorry, any real trucker would scoff at you trying to say 8 years is anything significant) that you can't learn anything new. That regardless of what Dodge says to do, they must be trying to BS you, and that you're right and they're wrong. Also saying that its been "knock on wood" for 30k is laughable. Try saying that at a mileage that actually matters - like 70k, or 100k, hell even 150k. You should be able to get 250k out of these engines minimum, 30k is barely a drop in the bucket.

Just that way of thinking is so flawed now, drive it until it breaks? That is how you get ridiculously expensive repair bills. A slight engine tap from an out of adjustment lifter because you ignored the valve train adjustment schedule? You could have spent an hour or two adjusting them or bring it into a dealer and have them adjust valve lash, but no you just keep driving it until something breaks. Valve lash gets so bad a pushrod gets bent and wedges itself between something, holds a valve open, piston smashes into the valve and breaks it, and next thing you know you have a destroyed head, destroyed bore and destroyed piston.

I find its people like you, the kind that boast their "experience" and "knowledge" and that think they know better then the people that built the truck are the ones that come complaining and yelling that their vehicle is junk when something serious finally goes wrong, even though it could have been avoided with preventative maintenance. Sorry but time and time again with any and everything, cars, trucks, computers, whatever, its the arrogant people like you that always end up with the biggest problems. Now I may eat my words, and you could be problem free all the way too 300,000 miles, but is that likely? Probably not.

Well I'm 24 and am a technician @ Honda. I would def have to say that this guy is way wrong I do firmly believe that the service intervals are very important. I always follow all the maint. on my truck to the "T". I even changed my fuel filter early because I know what comes out of these fuel pumps from experience with gas alone on Hondas. I just got back from my Road trip to Vegas and was thinking about my diff fluids the whole time. I left with 12700 and came back to 17200 and the whole time I was like man I shoulda changed it before I left. They are due @ 15k, so I changed them and just like I thought the fluid was horrible and contaminated, dark gray and smelled bad. So now I feel better thats its all gold and purdy! But I feel dodge isnt screwin anyone over about the maint. The cost yes but the service intervals no. They are recommended @ the milage stated because thats when fluid break down occurs. On hondas we actually have a severe conditions list of maint. Like incliment weather and city driving. Everything around takes a toll on our fluids so just take care of your truck as stated by dodge. A lot of people on this forum are obviously hands on and mechanically inclined so do it yourself but just follow the book. It helps to have a happy truck
