With the hard freeze approaching, I'm worried about my diesel fuel gelling around 10-15*. I've seen some ant-gel products but haven't thought about using them until now. Are there any negative issues with using an anti-gel and what brand would you recommend? TIA

I used the Sta-Bil Anti-Gel when we had our diesel Wrangler and it worked as intended. I imagine any of the name brands work fine though. If you have a block heater use that as well if able.

Try this. My buddy has a 2016 6.7L that he uses the supplement with when it gets chilly.

Diesels get 'left alone' until the temp gets back above freezing for a while. I just drive the gassers until then.

I've used the Power Service products for years, no issues. Stuff really stinks though, I wear disposable gloves when handling. Make sure to run the engine a while after adding. Good luck!

I treated our forklifts, snow pushing tractor, and my Duramax with Howes Diesel Treat in preparation for our sub 0 temps coming up. We have had good luck with it. Something most people over look is making 100% sure there is absolutely no water in your fuel filter, so no ice particles cause restriction.

In the deep freeze of 2021, I remote started the Duramax at -20 and let it run up to operating temp on #1 diesel without any extra fuel treatment in it.

If you get the Hot Shots Secret EDT Winter stuff, it smells nearly identical to Diesel Kleen. One drip on your shoe and the whole truck will smell like that.

You strike me as the type of guy that kept his grandmother's toilet paper from 1987

Dang, I definitely forgot to treat my skid steer.

Not that I need it anyway right now

I have no idea what this means.

I think i meant it as a compliment to your sense of smell. Remember how the old grandmother's had colored TP that was scented?

Kubota G6200 didn't need any anti-gel

I used Howes twice before and had gelling issues. Used Hot Shots EDT this go round and had no issues. I will be using it exclusively moving forward.

I've never used an anti gel and have never had any issues. Is this a post def issue? My trucks have all been pre emissions

Mine is deleted. Both times I had problems, I had to start my truck while temps were still in the low 20s. It started and ran both times but I had to change the fuel filter. This time with Hot Shots, I had no issues. I have no idea if that was the deciding factor but that is just how it played out for me.

No, this is an inherent property of diesel fuel. #2 diesel gels usually somewhere between 10-15F. Some biodiesel blends can gel at much higher temps. If you are up north, almost all fuel stations switch to either a blend of #1 and #2, or just straight #1 in the winter. #1 diesel has a much lower gel point so it can be used without any kind of treatment.
