What is a good choice for a diesel lubricity additive?

[John Jensen]

I have had fuel gelling issues here in Wyoming and since that I have used Power Service at a suggestion from brother in law and no issues since but when Winter comes here in Wyoming, I have found that if enough questions are asked, you can find who sells Blended Fuel and that helps also. Just some history of my asking about this issue.

Cummins recommends it as well

I used Opti-lube Summer to up Cetane in my 22, as for anti gel for Bio diesel I use Howes or Power Service winter... I never saw any mpg improvement in fuel mileage from Power Service summer when using it in my old 2006...

I prefer power service in the grey bottle. I used hot shot secret edt and it was garbage. I used the bottle over the course of time and noticed worse gas mileage and way more regens. It seemed like every time I drove it, it would go through a regen. I went through a few tanks of strait diesel after and immediately noticed fuel mileage improve and regen cycles go less often. I have gone back to power service but will only do it monthly or so. Btw mines a 2010 2500 with all emissions components.

Hot Shots Secret.

LX lube in warm weather, EDT extreme in the winter.


Started using after the recall of the CP4, and even now after having the recall performed, I will continue to use it.

whoever eventually gets this truck, either after sale, trade, of my passing, will bet a pampered unit!

Back when they first went to ULSD 15 lube test were ran on many fuel additives to see what ones that added lube for pre 2007 fuel systems, IIRC one of them was Opti-lube XPD al in one fuel additive.

If anyone is in the southeast area, I recommend southern states super gold diesel.

I have to ask how does one know any additive on a modern 4th gen Cummins does anything??? I am not talking keeping it from gelling the fuel.

That's a great question.

One doesn't know unless they see a change, for example, in mileage (which I've never seen). Personally, I use additives in my trucks for preventative maintenance. I'll never know if they are effective but I believe they do what they are advertised to do. For example, if fuel additives are keeping injectors clean that's good. If oil additives are helping to lubricate, that's good. It is a fact that diesel fuel quality varies among the states and additives can improve poor fuel quality. While those facts are real, one does not know if the additive is actually improving the fuel quality or increasing the fuel's lubricity.

I used to sell additives to dealers and retail. I can say there are some that immediately correct a problem and one knows it, Archoil AR9100 in a Ford 6.0 with stiction is the best example. I've heard a lot of stories of how additives helped and from the nay-sayers about why additives aren't needed or are snake oil. One fact for sure, I've never seen, heard of, or read about a case where an additive caused a problem. Yes, Slick 50 caused problems but those days are long gone.

Additives are or become a personal thing, you either do or you don't. I do.

Its called Testing.. I posted a link above on testing that was done to see what products added lube to diesel and how much it added, it showed some well named products that did not do so well...

I’ve referenced that test more times than I can count over the years. Sure would be nice to run that again since it’s been 15 or so years since.

It may be nice if it was but is there a need to redo it being todays injectors & pumps are made to work in todays ULSD, also you can bet the cost to redo the testing today is most likely many time's what it was back in the day, I have doubts many would be willing to part with the $$$$$ to fund the testing...

That’s true, but you wouldn’t have to test what’s been tested before, just what’s new and a current test of fuel.

I used Stanadyne in my 12V who knows if it did any good. I have used nothing in my 15 I am at 97k with zero injector issues. I do use OE filters.

I'll buy an once of prevention is worth a pound of cure. Long time power service user, our TDI and Cummins never had a fuel related issue. I froze up the TDI once, never happened again after using power service.
