Talked to my service mgr at the Ford dealership. Asked what anti gel I should use on the new 6.4. told him I always used Howes on my old 7.3. He said (for what its worth) not to use howes on the new 6.4. He said to use to motorcraft pm-18 (probably just trying to sell his product). So I bought 2 bottles of pm-18a. I get home and read on the bottle were it does not meet low emission stds etc, etc, etc, for 2007 and newer diesels. I went back to the guy and he said "Well I'll be darned". Might be a good thing I didnt use it. The guy then gets on the phone and talks to ford and they say to use the new improved version of their anti get pm-23 (I believe thats correct as I am away from the bottle). This is just what I'm told to do. You guys do what you think is right!!!!

I use Lubrication Engineers 2410 product. I went from regen's every tank to every other tank, I don't know if this is coincidence or not. I have used this product for years on my old Dodge, it smoked much less when i used it.

Owner's supplement guide calls for PM-23-A (US) or PM-23-B (Canada).

 

IMHO you should be careful using an additive that is not made for the ULSD there could be warrenty issues. Use the pm 23

 

I've put on 13000 miles and been through -10F already without any additives or anti-gels. I haven't had a problem other than a climate control temperature sensor ont he passanger side. Gotta love the crisp Fairbanks AK mornings.

Have you guys had problems with the fuel gelling on the ULSD?
