Do any of you use a diesel fuel additive? I thought this analysis was very interesting.

Thank you for reminding me. I need to put some in the tractor to keep the fuel from gelling up.

I use additives in my Tractor (1996 Kubota L2350).

Running perfectly all these years later.

archoil AR6300 is the Winter Diesel Treatment version of 6500… FWIW, I switched this year from Stanadyne but to be fair Stanadyne has a separate Lubricity Formula product(purple bottle)

I don’t have a modern diesel truck but I’ve never added anything to my tractors and never had an issue. I don’t run a tractor when it’s 20 degrees outside though. Is that the reason folks add it to trucks? Running them at night in very cold conditions?

We currently have 48 trucks and pieces of equipment with diesel engines and letting the fuel gel inside a single one will cause major issues so I buy this stuff by the cases and always put it to use when the temps fall below 25 degrees for multiple days. [Linked Image]
One trackho gelled up during the big freeze due to it being forgotten about on the side of he road from a previous project and it seems like it was around $14,000 in damages to repair. It’s a cheap insurance policy in my book, we also run some Amsoil injector cleaner through all the equipment every so often as well but I’m not sure that does very much if I’m being honest.

Good stuff. I use it as well in cold weather. I also add it to my holding tank for the tractors when I buy fuel for them.

My truck gelled back during the big freeze and I had to use this to get it started.

I know what I am doing at work tomorrow. And the stores will all be sold out of the good stuff. Better take my chicken lamp to work.

That’s because you live in north central Texas roflmao


It’s the single digits where there are problems. Further north you go the more anti gel is already added…. Normally. Not always the case though with bulk buy. Most the newer trucks with HP fuel rails start easier then glow plugs as it is though. I normally have more issue with not having oil pan heater then I do fuel, but I grew up in panhandle so fuel additive is second nature

I ran DieselKleen in the freeze of 2021, but never did after that. That Ram I had didn’t not have a way to plug it in and I was driving at either 9pm or 6am. It would take about 4 cycles of the key before it would fire off.

The new Ford doesn’t have a plug either. It’s not cold enough this time for me to be concerned about any additives. My biggest concern is the DEF fluid, what temps will it freeze or gel or whatever it does?

I believe the Ford DEF tank has an internal heater.

BigPig, it looks like the freezing point DEF is 12°F.
On the wife's Ecodiesel Jeep Wrangler, it stays in the garage, but I also keep the DEF tank at less than half during winter so if it freezes it will have room to expand.
If we need 4X4 when it's really cold, we take the Taco TRD.

PowerService isn't just for cold weather.

It is a lubricant as well as anti-jell. Might be something to consider running all the time if you are concerned about that CP4.

My DEF heater has been out since ‘19. My truck starts right up in negative weather. It’s never went in to limp mode from cold and I’m in negative degree weather atleast 1 or twice a year. With that said I keep it full in the winter and run the premium stuff

Usually your truck won’t go in to regen until engine is a certain temp anyway

I’d be highly concerned with any CP4, it’s a ticking time bomb barf

So I shouldn’t mess with it? I have read about it causing problems too.

It will freeze at 12 degrees. Just make sure your def is not full or the def will expand and crack the tank.

I added additives to my 2007 due to lower sulfur in 2007 and less frequently on my 2011 and 2017. Have not used any in my 2023 with 36k on her now.

Simple question.

Opti-lube in XL or XPD?

Archoil?

Which would you run?

Edit not worried about the CP4 at all have logged over 800,000 miles in diesel engines. Just don’t let the fuel tank get below 1/4 tank and use high volume gas stations, along with don’t fill up if a tanker is there filling the diesel tanks on site.

I use the same stuff that Ol Thumper does. Just now put it in Kubota tractor and RTV900, and took some to the neighbor for his tractor.

The low here is estimated to be 24 degrees. Like someone said, it won’t be THAT cold, but I suppose I’m just overcautious these days. I’ve replaced enough busted pvc for at least one lifetime. So, I winterized everything but the cat. All that’s left is to worry about what I forgot.

I guess I’ll add more firewood to the house rack.

Thanks BOBO. I only drive my 7.3 once or twice a month. Never had a starting problem but did experience the lurching before warming up the other day so ordered the ar9100 and the ar6300. I never run any oil additive but saw so many good reviews on this stuff I had to try it.
