I have done every fuel filter change on my truck except the one that was done as part of the CP4 and fuel system replacement when the pump failed.
I am well versed in the change procedure, and how to prime the fuel system after changing the filters before starting.
Also, my truck is never used off-road, doesn't get operated on any extreme inclines and never gets run extremely low on fuel.
I believe it is just the poor design of the pump and poor materials used in its construction that causes the failures.

 

 

That was a good video, Lake Speed produces some great stuff. Good to see XPD is still so above and beyond. I do wonder what the return curve looks like this.... for example is a HFRR of 230 twice as good as one of 460 with respect to the life of a pump or 10 times or 1.25x....

As a stanadyne user the result of the "performance" formula doesn't surprise me. It is almost the exact same as the result from the 2007 Spicer study. The lubricity version, which is the one I run, performed better but not in the same class as XPD.

 

There is a flaw in the testing that hasn't really been addressed. I want to see this test redone, but based on the same amount of additive across the board. XPD takes the top, so to get the proper dosage on my 24 F350, 48 gallon tank, thats 2 1/2 bottles of XPD, or 10 ounces. EDT is 2 ounces, so if it is boosted to 10 ounces, what would the test results show? Archoil is 5 ounces so a double or performance dose of it. This is one of the issues when trying to compare additives, they are not all the same amount of treatments per gallon. What would the results be if they all were applied at the lowest dose product? 1 ounce per 25 gallons?

 

Well, I went out to fill up my small additive bottles I take in the truck, and my big bottles were empty, thought I still had some left.
So, jumped online to chase prices again, thought about going with XPD, but it is quite a lot higher price than archoil.
And, then I found a discount code for archoil for 20% off, and they ship free but charge tax, opti-lube doesn't charge tax, at least to Texas customers.
I thought about just getting the XL lubricity treatment, but ultimately decided to give the archoil another shot, so ordered two big bottles of archoil, cost $77.86, and will treat 800 gallons of fuel.
By the way, the archoil 20% discount code is POWER

Opti-lube doesn't do discount codes.

 

I have read a few examples of people mixing the Opti-Lube Summer and XL formulas which should yield better results in this test according to the info posted on the vendors website. It is also cheaper than XPD as well.

 

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?

 

That's because the Archoil is also a DPF cleaner, while none of the others are. As I understand it, iron isn't an uncommon component in other fuel borne catalysts (FBC) that are used and promoted as DPF cleaners. I use Better Diesel FBC and pay attention to the iron levels in my oil analysis. So far they have all been normal though. However, what interested me in the Archoil more than the others was the fact that if (and most likely when) I went to it I could stop buying 2 different products and just go with the Archoil 6500 to replace them both. Otherwise, if I went with the OptiLube, I would still want to use the FBC along with it.

 

Well, one of these days i'm just going to say screw it! And, get the DCR conversion done and go back to being a non-additive guy...

Make my daily life easier and cheaper!

 

Come join the club! Just sticking with EDT for ease of 1 container with dose amount built into it.

 

I think it would be better to mix the XL and the BOOST version. Then you’re getting maximum lubricity and maximum Cetane.

 

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.

 

This came out today.

 

Simple question.

In the south, Texas Opti-lube in XL or XPD?

which would you run?

 

never mind
don't do math in head while head on crooked
