I'm sorry to sound like I am beating a dead horse but comparing the test results from the Farm Guy to an independent lab testing to a known standard is like comparing an NBA team to a high school team.

The wear being measured by the lab is measured in MICRONS. Farm dude is measuring in millimeters (mm). He does not have the ability to perform the test in what is deemed a meaningful manner by the engineers that developed the wear standards in the first place. Just because a lube did a "good" job in the Farm test does not have any bearing on how it performs in "real life".

To put it in another format, the lab measured wear in microns from 240 to 500. For reference, 500 microns is 0.5 mm. Farm guy is measuring wear in large numbers comparatively. In other words, the resolution of his testing likely didn't even fall into the margin of error for the lab tests.

The lab was testing for wear one might expect in a real world application - measured in microns because the wear amount is small so a small unit of measure is needed to reveal the differences between the tested additives. Measuring wear in mm is meaningless in this application.

As far as I am concerned, his wear test is meaningless. It is well-intentioned, but meaningless for the CP4 application. HFRR (High Frequency Reciprocating Rig) is the defined method for testing this application and his test rig has absolutely nothing in common with a HFRR test, other than friction.

The anti-gel and such tests might be more meaningful, but again - standards exist to ensure testing against them produces reliable, repeatable results.

 

Based on the actual numbers a few of my friends get from Archoil, I'm still making the switch.

 

Yeah, I must admit, after hearing so many good things recently about the Archoil really has peaked my interest... When I first bought my truck I used about a gallon and a half of XPD and then went to the Hot Shots after also reading so many good things about it. I eventually addd in the FBC and since then it has actually been great. I get good mpg's, my regen intervals are excellent and my oil analysis are fine. But between all of the current fuel additive threads that suddenly popped up, alongside the videos, it has made me wonder "Am I using the "best" one...?" LOL. So, I went ahead and grabbed 2 bottles of the Archoil using the POWER code for $68. I figure those 2 bottles will last me a minute since I will just do the standard dose. I am thinking I will use it for the next full 5k miles and see if my oil analysis looks any different with it. Of course I am curious to see if it does increases the mpg's like some say (although, I am really skeptical about that) and also curious to see if it changes the sound of my engine any either... If no change I may just go back to the Hot Shots and FBC. Well see.

 

EDT claims to be at 453 wear. That lab result puts EDT exactly AT their claimed wear. Compare Archoil, EDT and XPD, OK, now Archoil uses 4 times as much additive but not for 25 gallons, but for 10 gallons.

What kind of wear rating would you get if EDT was tested at the same dose as Archoil? Now XPD is 10 times the dose of EDT, what results would that give?

The wear test PF does is OVERKILL! Even so, the results bear out the truth, Archoil and EDT claim to have low wear, and even though hes using a grinder instead of the calibrated lab tool, the results still are comparable. It made be a crude piece of equipment, but he is using it the same as a lab would, a set tension across the board, a set RPM, and a set time. The only difference between all the tests is the sample of additive.

 

It seems EDT is not interested in increasing the dosage otherwise they would to sell more product. Maybe they already know it does not help if you double the dosage. If you really want to know the answer to your question, it would be awesome if you were to arrange the test with Southwest Research. This would then confirm or deny your thoughts. It would also help the community. Until then, I will stick with Opti-lube.

 

Kinda makes me wonder if this wasn't rigged. I haven't seen any diesel in years that didn't have at least some bio in it. What they tested appears to be straight diesel. Every Valero station that I have been to says this "contains Up to 5.0% bio or renewable diesel"
B5 has a scar value of 338 from previous tests. I think they are selling additives....... LOL

 

Note that the last item on the list, added to Diesel, removes lubricity. Kind of defeats the purpose of an additive.

 

Ah you are correct, the stations CYA is “up to 5% bio”. That means they are covered to provide 0-5% bio and not get sued for fraud.

 

Velero uses renewable additives to their diesel which is not as good as bio.

 

Pumps say what I posted. So either it has no bio or rigged to sell additives

 

Majority of fuel stops I go to have pumps marked B20 Up to 20% Biodiesel.
Doesn't mean it is, but could be.
