Home Forums Hunting & Shooting Hunter's Campfire Ford 6.2 gas versus 6.7 diesel...

in cold country you want number 1 diesel its a thinner winter fuel that gels less and at lower temps ..standard fair in northern Canada October to March.

norm

That - or at least visit stations that blend a certain percentage of #1 into the mix (usually about 30/70 here) to prevent gelling.. It's also wise to dump in some diesel fuel treatment to help engine health overall.

As to those old Oldsmobiles referred to in DMD's post above, GM nearly ruined the entire diesel market with that pos diesel-converted-gas 5.7L gas engine... Gawd, those were awful. Most refused to start when temps got below freezing. I know several men around here who'd had one of those and literally parked 'em around Nov. 15th and brought 'em back out in mid-April so they'd be usable..

Today's engines are literally night and day difference from those of old..

Any of the newer diesels with def and variable vane turbos can be problematic depending on how you drive them. Short trips with no load are the worst, if you get it on the highway with a load frequently they seem ok. Those emission systems need to get hot to regenerate and clean themselves. Our local fire department and ambulance service have had a heck of a time with all the brands, nothing like going to a fire and have the truck go into limp mode because the exhaust particulate filter is clogged. Besides in the winter the gas engines heat up in half the time.

if you don't want to use def.......then delete your diesel......I think just about any gasser will go 250,000.....with proper maintenance.....bob

Another point on the new diesels is they don't allow you to idle them. Well the sausage-head that came up with that plan doesn't spend many months a yer in sub-zero temps.

Can't speak for the other makers, but my 6.7 can idle for 15 mns at a time, then a simple press of a button on the fob gives me another 15..

It was -15F here a couple hours ago. I warmed it up for only 10 mns and when I got in it was already blowing warm air..

you can idle it , but it could result in clogging up your DPF if you do too much idling......things need to be HOT when you go into regen

Not sure what this is?

I can idle my 2017 6.7 for as long as I want to.

The DPF comes on periodically, but only at running speeds.

That sumbitch'll knock the MPG's down when it's running too.

they can give you trouble when its subzero .....things just dont warm up like they do at hotter temps

keep in mind , that DPF is catching carbon particles anytime the pickup is running , eventually it will need cleaning or replacing ( if you keep the pickup long enough)

chore tractors with dpf are a problem up here on the tundra , running a short time at subzero never really gets the motor fully warmed up

That DPF on my big tractor burns hottern the hinges of hell.

If it's overcast you can see the exhaust pipe glowing. I can smell it when it's on as well.

True - but I don't let it idle too long anyway; it's just not needed.. At least once a week I take it on the freeway and 'blow it out', so to speak..

As far as gelling fuel,
Old "normal" diesel (pre-93 or 94) would gell around -5F.
Post 2007 USLD <15 ppm sulphur can gelled at +17 if the sulphur is low enough.

All untreated of course.

A little K1 kerosene will help pour point and add sulphur which will also help. But, be sure your engine can handle the sulphur, pre-2007, mostly.

Looking at Ford's website I see their is an 'engine idle shutdown' option.

I'll shut the sonuvabitch off when I want, WTF?!


Speaking of idle, the farm's '11 6.7 has 72k miles. 1166 idle hours and 3600 total engine hours. Hell we've used the aftermarket hydraulics to run a Silencer squeeze chute, I bet the Ford engineers would really scratch their heads at that one....


I had trouble with the fuel/water separator icing up last winter(not the pickups fault...) but so far this year it has been trouble free.


Try and watch the weather and if it's predicted to get really cold, like -30F or colder, I will mix in a bottle of Power Service fuel supplement. Other than that just straight #1 fuel and it's good to go.

This!

Who comes up with this chit, I mean seriously?!

Government.

Yep.


Sad but true.

Mine has that new My Key programming on it.

That stuff is insane!

Sam, I have a 2012 F250 crew lariat, short bed 6.2

I like it, I can pull 15-16 mpg empty, I've pulled it down as low as 8, large enclosed trailer in wind. I went from 6.4 diesel F250 to this gas 6.2 and I'm glad.

Oil change intervals are on par with the diesel but the cost is wayyyyy less. If I do have engine troubles (I haven't) But if I ever do, the gas will be cheaper to work on. The service costs, the added weight of the diesel, the cold weather concerns... It's got enough power for me, no regrets.

I don't even want to know WTF that is.......grin





Actually the "My Key programmed" does show up when you run a systems check on the old '11.

I don't what the hell it is.
