I am buying a 2014 f-250 and have some extra cash to add or change parts on my f-250. Such as:
K&n cold air intake
Cat back exhaust
Headers
Computer chip or a programmer

Will these items void my warranty and is there some other things I can add to increase mpg that won't void warranty?

 

Quoted from Redford in 2010..."Don't you love spring, where the threads slowly transform from "my ESOF doesn't work" to "wow, this thing sucks fuel like a sailor swilling rum while on shore leave".

I'm gonna go out on a limb here and say yes they could void your warranty and there isn't much you can do to get better mpg.
I added an altec-eco compressed natural gas system to my truck(6.2L). My mpg is the same as every other truck i just pay $1.69 per cng gallon instead of $3.50 a gallon for regular gas. Good luck!

Keep it under 2k rpms, drive on the highway and not around town. I am not sure any part changes will pay for themselves at 1mpg or less improvement.

 

Not sure how much cash you are looking to spend, but for highway driving this can be a worthwhile investment...

Gear Vendors Under/Overdrive Ford Truck-Car-Van 4-Wheel Drive 4-Speed and 5-Speed Automatics.

 

All of the above will void your warranty.

If your concerned with mpg why did you get a 6.2?

The only way to get a constant mpg is keeping your foot out of the gas. Drive easy and you'll get the best results. Headers and a worthless k&n filter will only drain your wallet. Tuning will void the warranty most of the time. Personally after 14,000 miles I'm at 12.6 mpg avg hand calculated.

 

Except the cng system... it does not void any warranty. The company altec eco is a qvm through ford.

 

I need a f-250 to pull my travel trailer. The ecoboost is at its limits with the stuff I pack camping so f-250 is best for me.

 

Anyone have experience with the great vendor thing? It looks promising. I looked into the cng, and it seemed like its just a matter of when you're paying.(for me at least) It decreases fuel economy (by equivalents) and power by almost 30%. It'd take an absurdly long time to make any return on the investment. I work for an oil and gas co., so I'd love cng to catch on as a transportation fuel. (Buying American made fuel would be nice too) it just doesn't make sense financially with a v10.

 

the newer trucks(mine is a 2014) that were built with the gaseous bi-prep package are built to handle the cng. my truck shows little (if any) loss in power and fuel economy is the same as regular gas. I live in Oklahoma so cng stations are everywhere. If anyone wants to pay for 2 runs on a dyno to test the regular gas vs the cng i'd let you pay. lol

As far as return on investment it will take a while to pay for itself, it just depends on how much you drive.

 

That's really nice. The kit to convert my 99 was pretty pricy. I based the 30% on something I've read. I wouldn't mine seeing some real numbers either. The 30% wouldn't change the calculation much in my case, but I'd love to do it. I also drive fewer than 10k/year.

 

Have your alignment checked. Get as close to zero toe-in as possible (within limits of the spec).
Air pressure in tires - no joke, this is actually number 1. Bring your hot tire pressure to the maximum specified on the sidewall of the tires.
Purchase an economizer gauge (otherwise known as a vacuum gauge) and accelerate lightly to reduce the deflection of the needle into the lower vacuum numbers.
Drive at or slightly below the posted speed limit. Remember that it's called speed "limit" as that is the top of the allowed speed spectrum. Obviously you need to obey other signages with minimums and be courteous to other drivers..

When out on the open highways with no other traffic around, you can "surf" the road - IE, accelerate going down hill and allow your momentum to carry you as close as you can to the top of the next hill..

so lets say you use 1000 gallons of fuel a year and cng costs 1.69 and regular gas costs 3.50 (this is pricing for my area) and the conversion costs 10000. it would take you 5 1/2 years to break even.

now lets say you were driving 50,000 miles a year with all the numbers the same it would take you about 1 year and 4 months to break even.

I heard about power loss when reading old stuff on cng but I think the newer systems are built better than the ones that they had 10 years ago.
But in order for the cng system to make sense it has to be readily available in your area and where you travel.

 

Yeah 5 1/2 years on an already 15 year old truck is a long time. I travel I-79 through WV to Pittsburgh often, where there are stations, but anything around town I'd have to run gasoline. If i drove more I'd be more apt to do it.

Especially if the 30% decrease isn't accurate anymore. 8mpge highway using almost any fuel is awful.

 

Which oil and gas company do you work for m99? I was a geologist for 8 years and traveled all over wv and pa.

We were big into trying to promote the cng cars, but I couldn't stand behind their logic. Our company met with the government in dc to promote it, but for a year before that they flooded the market with natural gas to lower the price and said that when cng became popular they would shut off supply so that demand would be higher than supply and jack the price up to where it was even with or higher than gasoline.

 

I'd rather not say on the interwebs... But based on your location you could probably figure it out.

I think it has a real strong potential to be a better fuel. But it's not green enough for the hippies to make the effort.

But the no money mod is keeping your foot out of the throttle. Just finished a 400mile round trip (unloaded) and got a best for me 13.45 mpg.
