What do you use ?

It doesn't get cold enough here to worry about diesel gelling. If you feel like you have to add something I recommend Howe's, you can get it at Atwoods.

It absolutely does get cold enough for diesel to gel in North Texas. I’ve lived here since 2002 with a diesel truck and have experienced gelling on a few occasions. I prepare for it now so it hasn’t happened in a while.

Any of them will work fine. I stumbled upon SeaFoam which I happened to have in the garage in a pinch and it worked perfectly.

It definitely gets cold enough in east Texas. Most any anti gel stuff good. A lot of gas stations, especially truck stops already have in their diesel! Might check and see which ones have it in your area!

During the big freeze 3 yrs ago mine gelled up. Not gonna take a chance again.

Mine gelled at 11 degrees going down the highway once

My Super Duty did too that first morning. That afternoon with the sun shining on the truck it started. 7 winters with two different Super Duty 6.7’s and that was the only time it ever happened

Pulled my Blazer home and it started at home

I use the Power Service brand from Tractor Supply.

I have only had to use it once in 30 years here, that was three years ago. I just used whatever autozone had.

Please, someone provide picture proof of diesel gelling in Texas. Amarillo is fine.


I wanna see the pictures.

The gel in my hair melts in in February down here.

I have had signs of diesel gelling when we had extended cold and single digits temps in Houston. But my truck would still run, just took a bit to warm up and run better. Not worth adding any thing for those once in every 5 year occasions.

I've been in a blizzard, South Dakota. -16°. Parked overnight.


The fuel didn't gel in my truck or any body else's.

The diesel up there is #1 winter blend designed not to gel. Down here its nothing but #2 as the temps generally don't get cold enough.

Amarillo gets winter diesel.

It does get cold enough for it to gel. I’ve seen it happen. I always put anti gel in the tractor when I put it up for the winter because it’s probably still going to have summer blend fuel in it and I have needed it in the winter. I have seen it gel without an additive. I just used some stuff that comes in a white bottle at parts stores or Walmart.

At any time I have 100 pre owned diesel trucks at any given time. They will get, especially late model durmax trucks for some reason.

The next fill up. Put some in a mason jar. Tighten the lid and set it next the front tire when you get home. Anywhere you won't forget about it.


Actually see if the fuel gels.

I have had the rough running in the cold, but once the motor warmed up all was ok. Plenty of places in north and west Texas prolly get cold enough for a few days in the year to start seeing gelling

Diesel will definitely gel here. Happened to my brother during 2021 snowmaggedon. He lives in Lindale.

I kept my duramax in the shop and put a heater under the fuel tank and plugged in the block heater, and it was enough to not gel.

Up north they get fuel that has anti-gel in it. We don't get that down here.

Would be a fun experiment to put some in a mason jar. Never tried that.

I always used to use Stanadyne Performance Formula in my vehicles and never had fuel issues even when I traveled up north during the winter.

I use Power Services Diesel Additive every time we get a hard freeze. In 2010 while TDY in Austin, my 05 Duramax cranked and ran fine but it died at the main gate at Camp Mabry. We had to push it to the side until the sun came out. So yes, it can happen here in Texas. Also, I'm certain where we get fuel plays a part.

Hot Shots

Might need some this week

Calling for 7 degrees Thursday morning here. Filled up and added a bottle of Power Service today.
