2003 Ford F350 Lariat crew cab from North America - Comments

3rd Jan 2004, 16:40

I have a 2003 F350 crew cab diesel.

Or I had one last month!

I was getting 10 to 12 miles per gallon. At 3015 miles the turbo failed. The bearings shattered and were sucked into the engine. The truck has been at the dealers for three weeks awaiting a new engine. Neither Ford nor the dealer would supply a courtesy car. I am considering giving them back the keys.

My 2003 F350 ran fine for about 12,000 miles. Then it would lose power and struggle to maintain 60mph. Stop, turn it off, restart, and would run fine for a while.

Took it to the dealer that sold it to me and he tried to act surprised. I showed him all the printouts of known problems. 5 days later I got it back.

Back for a week and the check engine light came on. Bad sensor and not the latest program. Not sure what they did the 1st time.

12mpg is the best I've seen without a load. 9mpg with an empty 3 horse slant trailer.

Wishing I had a Dodge.

I Have A new 6.0L and it has 25000 miles. I have had no problems and have gotten as high as 21 mpg when you keep your foot out of it.

The new Ford f-350 6.0l is the best diesel anyone can own, it has no promblem pulling my 14,000 pound trailer or what ever I need it to do. The Duramax and the Cummings cannot even compete with the 6.0l. So when you see a Ford cruise by going 70 and you are only going 50 you might want to reconsider your truck.

Top review. If you like Dodge so much, go get one. And if you are gonna sit and put down Ford, maybe you should considder the fact that your Dodge Cummins has absolutely no where near the amount of power that the Powerstroke does. And unlike the Cummins, the Powerstroke is kinda quiet.

Why must these "men" as they call themselves complain about the fuel economy of the Super-Duty? It's a truck. A big one at that. It's expected of a vehicle of such size to guzzle fuel. The Cummins is a dwarf compared to the Powerstroke. Go ahead and stay with dodge... and deal with their transmissions.

Actually, the Cummins is not a dwarf compared to the Powerstroke. Here are the facts in this discussion, the Powerstroke produces 325hp and 570 ft/lbs. of torque, while the Cummins produces 325hp and 610ft/lbs. of torque. Looks like the Cummins "dwarfs" the Powerstroke when you talk torque numbers.

I have an 03 6.0liter. I bought it for use as a truck not a 35mpg sedan, If I wanted that type of mileage I would have bought a foreign car. This truck pulls my three slant load trailer w/living quarters around the states w/no problems. I have had minor issues, but then every thing in life does. Enjoy the truck and would not hesitate to by another one.

I own a 2006 f350 6.0 at 3500 kms the master cylinder went on it. Then the pedal sensor.

Then the steering box came apart, it was replaced then I had a headlight wiring problem.

Then the stitching on the seat cam out then the reverse lights and backup sensors stopped working now I have three bad injectors that make it have no power with 6 - 8 miles per gallon on the highway.

Buy a Chevy don't waste you money.

I just traded my Range Rover in for an 03 F-350 4 door dually. This truck is obviously not stock and it has so many options and accessories in it. Plain and simple this truck is beautiful. First diesel I have ever owned. This thing has amazing pull and pick up. I don't know what kind of turbos they come with, but it has a few treats in there some where. The turbo that is on there now is a Garrett and the tubed are different. It gets 15 mpg with a load or without one. The fuel economy is better than my Rover and 50 cents a gallon cheaper. All I can say is awesome awesome awesome. Looks like some of us got some good ones and some of you got some bad ones.

I only have one complain and it is the power steering is vertually impossible to turn when wheels are not runing.

I have an 01 7.3. pulls sleds, camper, and races from time to time. 125000 miles and never a problem. My point? If the 6.0 has left a bad taste go back to old faithful for a while, you'll be in love all over again. But seriously, the 6.0 is impressive, they just had a lot of bugs in 2003. A lot of 03 lemons gave the oval boys a nasty black eye. I do think they exterminated most all of those bugs though. Don't give up on old blue just yet.

I love my 2003 6.0 the power and torque is outstanding.

I have 563012 kilometers 300000 plus miles on it, and it still pulls strong with my 8000lb 5th wheel.

But I have recently ran into problems with it running rough in the mornings, and needing about 5 minutes to warm up.

Just doesn't like the cool mornings anymore.

I have an 03 6.0L that had the memory re-flashed by my local dealer because of a recall. Prior to the re-flash, I was getting 20+ mpg on the hwy, 16+ in town, and 13+ towing my 28' trailer. Since the re-flashing I am getting max of 17 on the hwy, 13-14 in town and 10 or less pulling my trailer. I asked the dealer if the re-flashing could be reversed and was told no.

Does anyone have any ideas to get my mpg back up short of spending $1000s?

Sorry lady about your luck. Good God I couldn't even remember all of that. Hope it worked out. I was getting ready to pull the plug on a used 03. Now I'm not. I'm going with the used GMC instead. Looks like you get what you pay for.

Oh man that's an awful story, sad it's not the only one of its kind. That 6.0 is a ticking time bomb. My insurance agent from Ike was driving a brand new 6.4. So we started talking about it and he evacuated to Oklahoma from Houston with all his horses in a horse trailer, and has a similar story to yours, but in the end had enough and traded it in on a brand new one.

We bought our Ford 350 dually new in 2003. It currently has over 128 thousand miles on the motor. My husband put a chip in our truck, and we get around 25 plus miles per gallon. We pull our gooseneck toy hauler, hauling a golf cart & mule, and have never had any problems. We love the truck, and will replace it with another Ford.

1. The Powerstroke beats the Cummins any day.

2. Let's not forget who makes the Cummins? Haha.

I have a 2003 F-350 6.0 diesel. I get about 12 miles per gallon. What might be the problem?

They circled the problem twice on the front FORD.

Hi, my name is Luis and I get 10 mpg. I need the tip. Can you send me the info? Thanks.

21st Sep 2011, 05:23

Is buying a 2003 F350 with 223,000 miles on it crazy, or does it still have plenty of life left in it for pulling a horse trailer? It already had the head gasket changed (or so the owner claims).

Looking at a 2003 6.0 F350 with 38,000 original miles. It is at a dealership. It has had 3 owners. Has a small oil leak that will be fixed before we buy it. Are we missing something?

17th Jul 2012, 18:45

I had the same problem. Just put 2-4 oz bottles of Rev-X in with your next oil change. It is the miracle worker for the 6.0. Trust me, you will be amazed how quick you will notice the difference. Go to revxoil.com and check out the video, it works.

2003 F-350 6.0L.
