That test does not match up with the independent lab tests that HSS had run. Both of the PF test results showed similar results as the independent lab tests did. In this latest PF test, Archoil came in by .03mm on the wear test, 5.17 vs 5.20. Those lab results don't line up with actual testing. There are also hundreds of others who have tried and posted good things about it. If you don't like it, so what. Don't use it. I OTOH am not seeing any improvements using Archoil over EDT so going to switch back to EDT.

I feel like we have certainly seen different people come up with different results performing different kinds of testing.
But….is it safe to say the OptiLube seems to always do well regardless in terms of lubricity?
I feel as though I haven’t seen someone saying it’s not one of the better options in that regard. And with that being said, lubricity is the most important thing we’re looking for an improvement with so it seems like it’s a great choice.
I’ve run EDT in every tank since new and had good results but it has me thinking about using OptiLube every time I see it perform well.

I'm not trying to be too critical, but given the history and the owner of EDT, I question any advertised claims including their claim to a third party testing and the pour lubricity test results that Southwest reported exposed this company once again.

Your free to choose whichever product you want to use by all means, but my goal is to expose the facts so people can make an informed decision. Having said that, IMO there's no testing laboratory that can match Southwest Research Institue. Even the big oil companies use this lab for testing and verifying their oil designs, gas and diesel additives just to name one sector of their capabilities.

Then how is it doing so well in actual testing against all the others? Explain that? How is it Archoil, which in those lab tests was so great, is only a .03mm smaller scar compared to EDT? How is it in real world testing it ranks second behind Archoil for wear and first on everything else, not once, but twice? Or is it just that you don't like the company so you rather bad mouth them.

I would love to try OptiLube. But for some reason it always shows as out of stock on Amazon. I think this might be related to the fact I live in Alaska. Same for Wal Mart. Autozone doesn't stock it either.
Any other choices to find it over the counter?

I ordered directly from Opti-Lube. I ordered a case of 24 and it was free shipping. Probably cheaper than Amazon anyway.

I believe this is an accurate conclusion. If lubrication was my top priority for a additive, I would ditch the EDT and go with Optilube no questions asked with what we know now.

And the test bears out exactly as HSS claims. Their wear claim is 453, what was the lab results again? 450? How much additive is used with EDT? 1 ounce per 25 gallons. How much is Optilube? 10 ounces for 40 gallons? With 10 times the product they had BETTER have more lubricity!!! Double, up or triple up EDT you will get results similar to XPD and Archoil, and still pay less per dose.

I have some Archoil on the way to try anyways. I'm gonna dose my next batch of diesel heavy with EDT to use it up.

And why didn't they test Hot Shot's LX4 extreme lubricity, like they did with Optilube's XL? Looks like the LX4 scores better than Optilibe XL.
