Additives?

I have talked to OL several times about the study. They will not publish it but if you contact them and ask about a particular additive they will tell you how it tested. I contact them via Facebook Messenger and they respond promptly.

Any test where a manufacturer won't publish how they reached their conclusion can be filed right in the trash. Tests have to be repeatable to have any validity.
Edit: And before anyone says "super top secret formula", that's why there's patents.

I have a diesel truck, John Deere tractor, compact track loader and skid steer ($300k or so) and I use OL in all of them. Deere's additive is made by Stanadyne but I don't use it because it's not very good. It has nothing to do with brand loyalty. I want the best product (price vs value) for my equipment. OL Summer is not the best but is one of the top four.
If you are sure you are using a biodiesel blend then you might not need an additive at all if lubricity is your only concern
The original study is here Lubricity Additive Study Results - Diesel Place : Chevrolet and GMC Diesel Truck Forums
And here https://www.dieselplace.com/forum/76...iscussion.html
You can either go by the Spicer study or better yet, why don't you put do your own independent study instead of just complaining about theirs?

Because I don't need to sell a product.

Hey guys! I'm new here and new to Ford and diesels. First off, this site is awesome! I have a 2019 F-250 larriot powerstroker that's 2 months old. Absolutely love this thing. I have read a little about fuel additives to lubricate and bump cetane levels, but they were fairly old posts. So what have you guys been using that you feel is helpful and where do you get it? I'm from Central Illinois, we have farm stores, auto zones, and O'Reilly's for the most part. Thanks in advance!
the 17+ HPFP has coatings that the 16 and older 6.7L trucks do not so lubricity additives are not quite so critical IMHO.
You need to ensure that any additive you use does not contain any alcohol. And you need to check your water separator at least once a month. Those two things will go further than anything else you can do to help your fuel system survive.

Until someone wants to replicate the Spicer study that is all that we have to go on other than manufacturer's info.
Just because a product is available nearly everywhere (DieselKleen) doesn't mean its the best. Nor is Diesel Kleen the best because Cummins approved it. All that means is they made a financial deal, just as Deere did with Stanadyne and Ford did with Gold Eagle

Illinois is one of the few (if not only) states that does not include an additive package with their fuel. When you pull up to the pumps you have a choice of No.1 or No.2 diesel. So in your case I'd say yes, you might want to include a lubricity additive in your regimen. Personally, I wouldn't worry about cetane in your case. I got great mileage and excellent power out of the tank of No.2 diesel I bought.
the 17+ HPFP has coatings that the 16 and older 6.7L trucks do not so lubricity additives are not quite so critical IMHO.

I could be wrong, but off-road diesel is considered off-road because it has the dye in it and it's not taxed the same. It could be #1 or #2, or a blend. I can buy #1 or #2 at the pump at certain stations. Most stations have #2.
