"better" and "best" are subjective terms with a question like this, and there are many discussions on this subject (hence the comments above).

I am quite happy with my 2005 3v V10 which has needed zero repairs since Sept 2004 when I got it. Initial cost was only $510 vs. more than ten times that for the 6.0 diesel at the time. For my situation the 6.8 was a "better" choice imo, ymmv.

However, every time I get near a diesel, a part of me misses my 2000 7.3 diesel (sniff)

I guess i should have explained this better. I'm looking at a 99 F250 Lariat with a V10 and a 04 F250 XLT with a powerstroke. I know they are both great trucks. Juat curios about the quirks associated with the different engines and if there is anything I should look out for with theae trucks.

Thanks for the clarification, that makes good sense.

A gas engine generally has fewer issues and maintenance costs than Diesel, and relies on fewer electronics to run.
The V10 is a powerful engine, but if you need good low end torque for heavy regular towing, a diesel wins out. Rear end ratios play into that mix as well.

My first question to you would be are you towing once in a while, everyday? How heavy are you toqing? Doing a lot of commuting and if so how far each way?

As a former 6.0 owner the 6.0 diesels trucks can be good if they were maintained and if whoever had it didn't beat the hell out of it. The problem your going to face is finding a decent 6.0 for a good price that your not going to have sink a ton of cash into and that will be the trick. I have also driven the 6.8 v 10''s and while they arent a slouch they definitely can pull their own weight and then some, might take a little bit to get used to the sound of the engine when she pulls but the 6.0 isn't quiet either...lol

My first question is do you have a budget in mind for what you want to spend on a truck? And with that said do you have a reserve set aside for anything that may pop up after purchase? I would seriously consider having a budget in mind of what you want to spend and a reserve in case anything comes up suddenly that needs attention. I dont know if your really mechanically handy , there are guys here who know the 6.0 and can put one together and others that know this and that but the truck goes to a shop that knows the 6.0 for repairs if it is anything out of their ability, that is something you will have to factor in as well.

The problem with some 6.0 trucks and if they are high milegae is that some guys are selling because they have moved up to a different diesel or down cause they dont need one any further and others that know their truck has issues but want to get as much as they can and dump it on the next guy and other who will straight up tell you it has issues. Trying to find one out of the group will be a test of patience and due diligence.

6.0 trucks might be ok, but others just might be to the point where they are tired or in need of repair that the owner isnt prepared to go and do. The chore for you will be to find out which is which. If your going to be buying a truck privately ask the current owner how long they have had it and if they are a 1st, 2nd, 3rd, or 10th owner, ask if they have maintenance records, those will be very very important to seeing how well the truck was maintained. Did the owner do a lot of his own maintenance or did he have a shop do it? whats all been done to the truck, how often did he do oil changes, filter changes? Is it deleted? is it stock? was it tuned? What kind of tuning and by who? Why are they getting rid of it? etc

Dont just take the persons word for it that they were the only owner, run a carfax or car proof and verify the trucks history, lots of shady guys will buy truck at auction and song you a song and dance to get you to buy it so they can flip it for a profit, now thats not inductive of everyone but you need to check the trucks history out.

When your going to go loook at a truck make sure you take some coveralls and a good strong flashlight crawl all over the engine of that truck and look for leaks etc, then crawl under the truck and do the same, get right under that engine and use that light to look for any leaks from the front of the engine to the back and side to side. the 6.0's love to leak from the bedplates so you need to look really well follow it all the way to the transmission and look for leaks. while your there check the steering components, tie rods, ball joins control arms etc... and work your way to the back of the truck. Start that truck up and let it run and look for leaks, check the coolant bottle and see what the coolant is like and make sure it isnt puking diesel, let that engine get hot, take it for a good drive on a fwy or highway and keep an eye on those temps etc, check that exhaust and see if it is belching oil or yellowish white smoke. check if there are any CEL's on etc.

Whether your looking at a 6.0 or a v10 dont plunk your cash down just yet If you like the truck just cause it looks good on the inside and outside, tell the seller you would like to arrange for a Ford dealer to inspect the truck ( see below )

Maybe a truck your looking at is at a Ford Dealer, or another dealer or the guy on the corner selling trucks? Ask the dealer where this truck came from? It is important to know the trucks history. Used car dealers only get their trucks via trades or at the auction. You need to know the history. Get them to show you a car proof or a carfax and see where they got it from

I would ask the dealer to see a car proof on the truck and see what it say's. If things look okay on the car proof then I would ask the place selling it to allow you to take the truck to a Ford dealer if it is at any other dealer from a big dealership to Al's auto lot on the corner selling trucks

Still need to check if the truck is at a dealer if the truck has been tuned or deleted? That is another thing important to know. Some guys that have invested time and money into a tuned truck that has been deleted arent usually selling them with some mileage, because once tuned and deleted these trucks can go along way if they were taken care of and if they were maintained right. If some guy beat the hell out of it and dumped it because it was a problem child then thats something to be wary of. But that is why I suggest taking it to a Ford dealer and having them look it over with IDS.

It may cost you a couple hundred dollars to have a Ford dealer look at it, but if your thinking a v10 and especially a 6.0 have a dealer look at it, You can get the Ford dealer to use their IDS to check the compression in the cylinders,( for the 6.0 the FICM, ICP AND IPR readings and the injectors) not to mention the Ford dealer can look at the breaks and suspension and front end components and most of all check for any leaks etc. A couple hundred bucks spent now could save you from having to spend thousands later in repairs.

Even if some dealer says they had it inspected, still take this to a Ford dealer and get them to check the truck before you enter into an agreement to purchase it The Ford dealer should know what the problem areas of the 6.0's are and they can tell you straight up what the scoop is, and the same with a v10 . I would not enter into any purchase agreement until you see what the Ford dealer or a shop that knows 6.0 diesels tells you what they found after they tested things with IDS and they looked over the rest of the truck and that would go the same for a v10

There is also a huge differences in costs of parts and repairs btwn a 6.0 and a v10. You have to remember that 6.0 parts are not cheap, remember that Navistar still has there hand in the pocket of 6.0 and 6.4 owners when it comes to parts. I would advise you not to go to a 6.4 just because the curve on those truck is steep and repairs can be pricey and there are a lot of guys dumping 6.4 problem child onto someone else because they just dont want to fix the issues they are having, are there good 6.4's out there sure, but the upkeep and repairs can be really steep if you dont have the wallet for it.

Do your homework on all the trucks you look at, take your time finding a truck and then do the due diligence on it, if it looks good then take some of the steps I gave you and go thru them, last thing you want to do is spend thousands of dollars on a truck only to find out it need thousands more to get it on the road or keep it there.

Well it's a step in the right direction, but you are still asking us to decide whether gas or diesel is right for you and you haven't provided ANY of the information that is needed to make that decision.

How is the truck going to be used? Daily driver 5 minutes to the office and back with the occasional trip to Lowe's? Get the gas truck. Going to haul a 14000# 5th wheel cross-country? Get the diesel truck.

This is just the tip of the iceberg. Keep in mind the amount of information you provide relates directly to the quality of answers received.

Thanks for all the input. To give a little more information. On paper I've got 15 years as a mechanic. From diesels in the Army to motorcycles and boats as a civilian. You can add another 10 years to that working on stuff on the side. I just don't have any experience with these trucks, so I figured I would ask people that do.
I don't plan on doing much towing just willing to consider the diesel because I know if they are well maintained they can last a long time. However its been my experience that gas motors are less expensive to maintain. So if a well maintained V10 can last 500k miles without too many major repairs then I think I would rather go with the gas motor.
I have a budget because I prefer to pay cash and I understand there is alway the possibility something unforeseeable will break.

Given the track record of both engines the v10 is overall more reliable something to be aware of though is the 99 model year v10 is a non pi so itís down on power compared to the 2000íand up trucks and is really the only year v10 super duty I would avoid. The 6.0 can be a great engine but how it was maintained at this point is going to play a huge role. If your are serious about buying a 6.0 you need to buy some sort of obd2 device some you can monitor the vitals of the truck and pull codes and take it on a nice long test drive. If you blindly buy a 6.0 with out doing your homework your kind of asking for it. https://www.ford-trucks.com/forums/9...used-6-0l.html Give this a read as well as browsing though the rest of the 6.0 tech folder the only thing in there that I disagree with is the continued use of ford good coolant. Again the 6.0 can be a great motor and is backed a very stout transmission.

there are a lot of good reasons to avoid '99 rigs. there's a few odd-ball parts specific to that year alone.
