Agreed. They both likely contain a large percentage of PAO base stock. There are plenty of group iii synthetic oils that will equal or outperform many group iv synthetic oils in our application anyhow.

I will look.

Th Amsoil in question probably is alot of PAO since it is $13 a quart and uses manufacturers OCI's. Amsoil's claim to fame is the 25k intervals and that's why the extra money for their top tier oils. They now also have lower price point oils that are class III and the price reflects it. This is equivalent to the other boutique oils, Red Line, Motul etc. except they use an ester/pao base. The Mobil info is even less forthcoming than the Amsoil as to what is in it. Synthetic base stocks is a catchall for many of these products and doesn't explain the type of base oils at all.

Going to take a chance in posting this here as it is specifically Amsoil bypass related. Being interested at least in filtering particles smaller than engine wearing, have had trouble in finding resources for fittings and install pictures to go along. At least, no links I've been able to find with pictures uploaded that I'm still able to see, have had to find my own way to make the necessary connections. Should someone have such a resource, I'm game for it, until then, my specialty, modding it myself. This is what I've found so far.
Having seen this link http://www.42draftdesigns.com/vw-aud...elocation-kit/
in discussions of relocating the oil pressure sending unit, in combination with this https://drive.google.com/open?id=1Jd...UxXXZgpe-Qf-PC
I can build off of this part to make it more specific for what I want to do.

Just an observation. The 25,000 mile interval is for the Signature Series synthetic oils specifically for gasoline engines and non-heavy duty use which I interpret as mostly highway driving and not towing either.

For diesel engines Amsoil says to go by the manual and/or do UOA to go beyond what the manual says (10,000 miles OCI for TDIs vehicles).

Default For reference purposes: Amsoil Diesel Injector Clean lubricity improvement results

For reference purposes here are the lubricity improvement results by using Amsoil Diesel Injector Clean additive (from the Amsoil Fall 2019 magazine edition):



The lubricity test took the HFRR value of a D2 sample at 480 (wear scar in microns) to 350 with a treat ratio of 640:1 or 1 oz. per gallon. Here is the corresponding data bulletin:

https://www.amsoil.com/lit/databulletins/g3186.pdf

I thought it would be good to share this info so everyone can compare to other products with recent test results.

Diesel Secret LX4 had some amazing results in testing. Unadditized fuel went from 610 to 270 and pump fuel from 399 to 225. At 512:1. If I were to use something it would be this stuff.

I am trying some of it now. Don't notice any difference but didn't think I would anyway.

That's correct Lightflyer1. It is nice to have recent lubricity test results as the ones published in the last few years by Optilube, Amsoil and Diesel Secret rather than 'recycling' the one some folks keep on posting from way back 2007!

The Spicer report was getting old! Nice to see newer actual testing results.

By the way, I do not think that it is coincidence that the average HFRR value for the state of Illinois is lower (better for lubricity) than the average of the other states since Illinois has a minimum mandate of I think 10% to 20% to blend biodiesel in D2.

Just wonding where everyone gets their info from. Sounds to to me a lot of people misinformed. Amsoil is a group IV oil yet someone had hinted at the low saps 5w30 is a III. Yes they have OEM type oils, but for the price difference I would use their top oils etc. As far as oils are concerned Amsoil far exceeds all others. For the Porsche how long did he run Mobil in before changing to Amsoil or did they run Amsoil from brand new.

Amsoil sells cheaper group iii blends now too. I wouldn't get too hung up on that group this or that garbage anyhow. What matters is how an oil performs in real world use. Boutique oils are unnecessary to reach ultra high mileages. This isn't F1.

Besides most cars will be sold or crashed or taken out of service for some other reason before you notice any difference between any high end oil vs any VW spec oil if even then. No use wasting money on something you will never see the difference from. Just an extra expense you throw down the drain. Especially if you are under warranty.

So I looked at their test results and I looked at Opti-Lube's test results of the XL and something doesnt jive.

According to Hotshot, their baseline fuel was 327m/399m and Opti-Lube XL tested at 308m/369m at the 1:512 dose.

According to Opti-Lube, their baseline fuel was 440m/580m and Opti-Lube XL tested at 220m/260m at the 1:512 dose.

So Opti-Lube shows a MUCH BIGGER improvement XL than HotShot does. Both tests were conducted using "pump" fuel.

I wonder who's cooking the numbers here.

Moot point for me as I stopped using it. Back to just pump fuel with 5% bio. Opti-Lube sure managed to find some skanky pump fuel though if your numbers are correct. Even the Infineum fuel report only found a max of 526 in their testing.
