I'm not from Texas but from what understand you have a minimum cetane rating that is satisfactory and don't often experience really cold temps. The benifit to the XPD over XL is cetane boost and some kind of cold weather additive. The upcharge for that is pretty high, so if you don't need either, the XL is the best bang for the buck. Summer+ is also another good option that gives you additional lubricity and some cetane boost....still cheaper than XPD.

It is not a flaw in their testing - they tested each product at the minimum recommended dosage. The reviewers said it - the "carrier" comprises the vast majority of the product. The actual additive group is very small - and is what makes up the wear protection part of the additive. The manufacturer sets the dose to meet whatever their performance metric was. This test revealed how effective each product is at the recommended dose - nothing else. If a manufacturer decided to make their dosing a full pint for 25 gallons, it simply means you paid for more of the "carrier", which brings no benefit to the wear component of the equation. What this test really shows is some additive packs are much better than others at preventing wear. Doubling the recommended dosing does not mean the wear numbers will improve. In fact, in the case of the Stanadyne PF product tested, it might mean wear is increased even more. Also - it was noted that increasing dosage can cause excessive regen cycles with some of the products.
The Opti-Lube XPD All-Seasons product states 2.5 oz. per 10 gallons. It costs $75.76 for one gallon delivered to my door. That is $8.88 per fill-up for my truck. A gallon will give me 8.5 fill-ups.
The Archoil AR6500 product states 1 oz. per 10 gallons. It costs $104.96 for one gallon delivered to my door. That is $4.92 per fill-up for my truck. A gallon will give me 21 fill-ups.
The Opti-Lube XL Xtreme product states 1 oz. per 10 gallons. It costs $67.78 for one gallon delivered to my door. That is $3.18 per fill-up for my truck. A gallon will give me 21 fill-ups.
The EDT+ Winter Defense product states 1 oz. per 12.5 gallons. It costs $79.54 for one gallon delivered to my door. That is $2.98 per fill-up for my truck. A gallon will give me 25 fill-ups.
The EDT Secret Everyday product states 1 oz. per 25 gallons. It costs $71.29 for one gallon delivered to my door. That is $1.34 per fill-up for my truck. A gallon will give me 53 fill-ups.
I was using the EDT+ Winter product during the winter months and their EDT Everyday product the rest of the time - but now I'm going to switch to Opti-Lube XL Xtreme. That product posts the best wear levels I can find - and the price remains reasonable, in my opinion. If it does get cold enough to warrant the use of an anti-gel, I will add that as needed. My #1 priority is pump and injector lubrication. For my money, the $3.18 per fill-up for more than double the wear protection of the EDT Secret product makes the Opti-Lube XL Xtreme the best choice for me. The Archoil is a compelling 2nd place because of the other additives, to include DPF cleaners.

very nice breakdown! From everything that I’ve researched my plan moving forward is to mix the Opti-Lube Summer and XL blends and then alternate in Archoil every 3rd-4th tank for the DPF cleaning. For now, that seems to be the most cost effective solution until a DCR is installed in place of the CP-4.

It is probably all just snake oil BS.

Didn't you move to Florida? If so, I doubt you have much need for the anti-gel aspect of the additives.

His testing did not properly cover the most important part of additives for me - the lubricity improvement of the various additives. As much as I like the Project Farm guy and his wide variety of testing, I'll take the scientific lab test results for my decision making process.

As for the lubricity, it was my understanding that this is what cuts down the wear scar, which he showed. In which case, the Hot Shot's did great at. It came in a very close second, right behind the Archoil. If this is the case, it really wouldn't matter if I switched from using Hot Shots + FBC or went with the Archoil.

It's all just a shot in the dark, taking what those product "test results" say on faith, you don't know if what they say is true or how they actually manipulated their data.
It is probably all just snake oil BS.

Archoil emailed me this morning, they have a commercial website where they sell larger jugs and cases of their smaller bottles, and at up to 25% less per ounce than on their retail site.
Of course with the 20% discount code they have it doesn't make it that much less, but larger jugs means it is a little more convenient if I keep using it.

your missing the point, the test was done with the manufacturer suggested standard dosage. As a consumer, I would only assume you would add what the instructions said to add. It is up to the manufacturer to determine the dosage rate. To be honest, the bulk of the fluid in the dosage is a “carrier” fluid. The product that actually enhances the lubricity is pretty small.
Another odd point is the amount of iron in the Archoil sample. I would like to see that tested again from a different lot # to see if that hold true. Has anyone sent in a sample of Archoil for analysis?

No, you miss my point. If one ounce of one product can treat 25 gallons with set results, how do the rest of the products compare, Ounce to ounce. IOW, if it takes 10 ounces of XPD to treat my tank, what kind of protection will 10 ounces of EDT give me? Lets look not at manufacturers dosages, but an apple to apples dosage rate. To me, this shows me which product has the best concentration of goodies per ounce. I add 2.5 times as much Archoil to EDT to fill my tank. If I add that amount of EDT, will I get better protection, superior to Archoil?
I want to see how they all compare on equal footing, one ounce to 25 gallons.

According to this chart, mixing the Summer+ and XL gives me a higher lubricity and centane level than XPD while still possessing some deposit removal and water demulsification capabilities. Anti-gel isnt a concer. For me as I’m in Las vegas.

There are several of these fuel additive threads going around now, both here in the 17-22 threads and the 6.7 threads. There has also been some talk about the diesel fuel from Valero in some of these threads as compared to the higher biodiesel found at many pumps, such as B15 and B20...
The video in post #88 put Hot Shots at the top of the list and Archoil wasn't too far behind. After watching the video in post #77 I was all ready to get ready to swap over to XPD, or Archoil... however, I think now I am just going to stick with the Hot Shots and the Better Diesel FBC...
I do like that these videos actually show that some of the fuel additives can actually make a difference though.
