Upgrading my 2019 F250 6.2 CCSB Lariat to a F350 6.7 CCSB Lariat. The 6.2 just doesn't have enough capacity to tow a 16,000 Lb fifth wheel.
Never owned a diesel before and I'm in Minnesota so it's cold. I have rented Diesel powered rental trucks for years so I'm not a complete diesel virgin.

Question is what things should I always have on hand for the 6.7? We run all #1 fuel up here so gelling is possible but not super likely. Is Diesel 911 the best/worst choice to have a couple laying around in case we get into -20 weather?
What about daily fill ups. I read here and there to put an additive in fuel every/every other fill up. What would be suggested there? Is there a best brand? Or have I read too much into too many things.

This truck will be a winter daily driver and summer time camper puller. Probably a fair amount of winter idle time when we are in MN but we will most likely be wintering in FL or AZ with it so we will pull camper, then use it as daily in town driver. I tend to drive a bit harder on stuff so I think that will be good for the diesel. Appreciate the suggestions.

Thanks

 

To be clear, you can't run unadulterated #1 fuel oil. It lacks the basic lubrication necessary for the high pressure pump. Just point that out since you can buy #1/#2 blends, and #1 as road fuel with the necessary modifiers and #1 without. It makes a difference. Just make sure you are using a proper road fuel. It's important to note that not all fuels are the same. Some are more resistant to gelling. That is why you hear a lot of folks saying they have no gelling issues at -20 and others have issues at +10. It just depends.

It's better in the cold climates, like where you are, to do pre-emptive actions. You should run an anti-gel. What brand does not matter one lick. I'll reference Motorcraft PM-21 since it is pretty common. What these do is keep the paraffin wax, which is a component in the fuel, in solution. It's my understanding that the 911 is for when you have gelling and need to get the wax back in solution. My impression might not be accurate since I don't know that much about all the additives out there. I've not made it my life's work.

You don't really need any other additives as long as you are using a proper fuel. I know the additive guys will freak out and pout that it's your truck and you can drive it to ruin if you want to, but the anti-gel in cold weather is the only additive that helps keep you on the road. And it's cheap enough that you can easily afford the protection. Again, you're protecting against having the fuel gelling. A very specific, provable thing.

 

We go to local "Holiday station store", Kwik Trip, Super america (or whatever they are called now) etc. How would we know what they have in their fuel for lubrication?

 

If you're buying it as road fuel, then it has the proper lubricants. Not something you have to worry about. If your pal, Barney, says he has a drum of #1, then you want to avoid that one.

 

If the pump is on the main fuel islands (for cars or the semi trucks) and is labelled as "#1 Diesel" along with the choice of "#2 Diesel", it's fine to use in on-highway engines, but still not a bad idea to add a dose of additive such as Powerservice or Optilube.

If the pump is off the side of the lot and labelled specifically as "Kerosene", you can probably assume it doesn't have any additive in it and is generally not intended for on-highway use, although it will burn fine in an engine. You'd definitely want to add a heavy dose of lubricity additive.

 

You are on the money here. Carry a spare set of tuel filters, Run an anti gel if your temps are below 20F consistently and avoid low volume stations.

 

You likely wont have a problem. Those guys down south who don't even know what #1 fuel is got themselves in trouble last week when that cold stuff came around. Some of those guys must have had summer blend fuel in their tanks from smaller gas stations. Major chain truck stops like Loves and Pilot I have a hard time believing weren't selling winterized/treated #2 since it is common for OTR trucks to fill up down south and head 600-700 miles north on a fill.

Ideally park the truck inside a heated building if it's -20F, or plug it in if that's not an option. #1 Fuel I have seen charts that says it's good down to about that cold before the filter plugs so I'd use it in the winter as a precaution. OTR trucks generally leave their engines running at night in those temps to keep the warm fuel circulating through the filters and back in to the tank.

 

I run Hot Shots anti gel in the winter and every day treatment in the summer. As others have said, lots of different additive options out there. I’d recommend using something every day vs, the 911 stuff, better to be proactive than try to react to a problem after it’s happened. If you travel a lot, keep a set of fuel filters on hand and the tools necessary to change them on the road if need be. Given your use, i’d go with 5W-40 oil, not getting into brands, just use something on the Ford list.

 

Slight correction to C12H24's post. The Motorcraft additive to use in the winter is PM-23. It has the anti-gel feature. The summer additive is PM-22.

I usually put in the PM-23 starting in October, when I go hunting. Last October, I pulled into the fuel station up in the mountains and asked if their regular diesel (#2) had the winter blend yet. It did not, so I bought the #1 diesel instead. It got down to -8° F on the mountain where I was camping, and even colder in the valley where I was hunting. My truck started without any issues.

 

Just run a winterized diesel. It will be available though fall and spring.
IMO, every tank should be dosed with an additive to increase cetane, lube the injectors and pump, and demulsify water so the water trap can catch it. Avoid emulsifiers. They make water droplets so small they pass right on through the filters and injectors. Not cool to have any water freeze in an injector.
One stop shopping that is available almost everywhere is Stanadyne.
There are others. Opti-Lube is very good. Bell Performance Dee-Zol as well.
As stated, don't run #1 solo.
Agree on 5w40 if going below 0 degrees. 10w30 is good down to about 10 though.

 

The diesel in your area is going to be cut to what it needs to be to keep you going. in the event you get much colder than normal weather you can add some Howe's to the tank and you'll be fine.

99% of the time cold weather diesel problems are due to an unexpected cold snap and the suppliers are caught with their pants down.

 

#1 fuel has poor lube value....you need a lube additive

 

You guys saying #1 diesel is a poor lubricant may be wrong. I can't find anything from a reputable source to agree with what you're posting.

The downsides of #1 diesel is lower MPG and higher cost.

The lower the number the greater the lube value. I think 520 is the target number. untreated #1 diesel does not meet ASTM or EMA min standard.

 

The sites I could find on this issue all mentioned that #1 diesel always has an additive.
