First of the first.Have been wanting to go from gas to deisel for while now and currently looking at the 2012 F250 Lariats. A couple questions I have is what can I expect for MPG .I drive 80 miles round trip hwy for work so thats why I'm leaning to go deisel.What's the deal with getting a chip installed when it's new or should I wait till the warranty is out. Any advice will be greatly appeciated.

If you want a diesel solely for gas mileage, don't get it.
You're mileage can be fairly good depending on weight, add ons, gearing, etc.
But your maintenance will be much higher than a gas motor. so unless you just don't care, it won't help you.

I've always heard the maintance on a deisel is alot less frequent than gas. I do understand that it cost more.
One of my other reasons for wanting a deisel was after 5 years the gas truck will have approx. 120,000-140,000 miles and won't be worth nada. On the other hand the deisel is just getting broke in a can handle another 5 years. Im trying to justify to myself for getting one of those nice looking 250's

Oil changes need to be every 5k miles when still running a DPF. If you don't not understand what a DPF is or how a regen cycle affects engine oil, do more research. Diesel fuel dilutes the engine oil basically. So that needs to be changed often. 13qts of oil, especially synthetic can be pricey, but worth it if you want to take care of it.
With the fuel systems being so sensitive, you need to change fuel filters fairly often, there are two. Many ppl will change it every oil change just to be safe.
Fuel filters are way more expensive than gas fuel filters that you can even change.
I'll say this; if everyone had to justify any purchase, we would all have WAY more money, be smarter, and I sure wouldn't have a 105gal fuel tank w/elec pump
So, if you want it, get it. But I don't want you to have any misconceptions about saving money with it.

Now, an older IDI or 7.3 is a lot cheaper on maintenance, but it'd take a decent amount of preliminary mods to get it to get "good" mileage

My 2012 F350 is showing on dash 17.1 mpg instant fuel mileage not pulling much yet but pretty much 80+ where ever I go in it. not stomping on throttle leaving stop lights. Annd have had alot of idling done. Added fuel just to top it off twice, no exhaust fluid yet.. seems what I read its around first oil change. Biggest trouble so far is place to park the long son of a gun, at angle on small streets its pretty much road block with its 8 ft bed, parallel parking bumpers just fit inside blocks and none can see around it. BUT wouldnt trade it back for nothing. Love my F 350
