Great video on oil aging as this topic has come up alot. HPL does the foam testing of the old oils and compares to new oils including mobil 1 from 1980-84 and new mobil 1. They speculate on the age of the mobil 1 but its atleast 1980 as its api SF and newest it can be is 1984 as in 1985 they switched to the round plastic redline style bottles

Ok, so if we want to go recycle w/o politics,

Riddle me this, crude oil is filthy right, and yet it is the base for all motor oils even redline. Not the ester portion but pao and any mineral oils. So if we can make crude into amber goodness, why cant we take used oil and rehab it in a similar process to refining crude? Is it simply economics? As in every single thing crude breaks down into is cha ching, but the only end game to recycling motor oil would be more motor oil which isnt terribly profitable in comparison? It cant be the simple use in an engine is harder on oil then billions of years of compaction with earthquakes and every thing else smashing it down? If it is possible, shouldnt we be storing used oil? My guess, the need is so massive we need crude to even come close to what we need to run automobiles.

can be
Never used it, but I believe Vavaline recycles used engine oil.

U.P. isn't part of the U.S., Mike.

They left after their bid to be the 51st state was ignored on the 70's.
I dont know how the ended up getting posted, wasnt trying to go there, thats on me.

Bottom line burning old oil is a reasonable way to make heat and/or energy, imo, which is not an opinion held in certain places or by certain people who prefer free bubble up.

Hey Mike - did you catch how TBN/TAN are not a reliable indicator of over-oxidized base oil?

I always used tbn and tan just to verify acid level, I am pretty sure those are good for this. I do like this guys theory on two types of moly makes a better plate then one type of moly. Gotta go back and watch the whole thing again, thanks travis and brian. That storage is a new issue as redline says there is no shelf life. Ha

Shaking is nothing compared to the rotation of oil in the engine, so if shaking is bad then circulating is ten times harder? I havent seen any foam on my dipstick for decades, I think once I remember seeing it on transmision dipstick, but it was a different vehicle.

Nope. Oxidation doesn't always correlate with safe TBN and TAN condemn limits.

I've written about this before. There needs to be an Oxidation condemn limit also, Blackstone doesn't offer, we had Mobil.

Yup one large downside to blackstone, in fact the only one that I have seen, no oxidation test.

With oxidation you need to know the starting oxidation value to before you condemn the oil. Oils with esters will have higher oxidation to start with. the old mobil 1 FS 0w40 oxidation started at ~40 same with the ESP mobil 1 but the current SP formula oxidation starts out at 7 like all other non ester oils. HPL starts out around 27. Im not sure where redline is at these days but at one time they were around 90-120. Different types of esters contribute differently and im not sure how each type contributes or which kinds of POE redline and HPL use

In the end, wear numbers should tell the story even if the oxidation is an issue. Plus some of the other tests insolubles etc. Probably why blackstone doesnt do oxidation, they think insolubles can say the same thing a different way.

Like travis was saying, not all oxidation tells the same story, but insolubles do tell that story.

Very true. If you sample multiple times throughout an OCI i would change it once i notice an increase in wear metals on a ppm/1k mile base

I looked up polaris, I want those ten minutes back, like wtFF? I hate looking for prices, sorry I was willing to consider trying something new, forget it. My college degree and I cant find a price, the problem is with you.

Oil analizers is better at least you get a price, but do you have to join amsoil to get one? Blackstone looking better everyday, lol.

I believe polaris and amsoil are the same lab

Lake speed jr has an oil analysis company to that gives oxidation. I didnt check prices yet but its speed diagnostix

Thanks Trav...

I'm not so sure actual oxidation test would trump insoluble testing, but hey at least perhaps we would learn something about redline and others, you say hpl starts at 7? The have to have some other labs with those numbers bITOG? I do see value in it, if you know the starting oxidation number you could forsee an issue before it shows up as accelerated wear and insolubles. Generally I have been more then satisfied with blackstone, they have some of those aha moments with some of the stuff they catch.

No problem. HPL starts around 27 from the VOAs i have seem thru oil analyizers on bitog. Wayne ran the basic group 3/poe/an HPL HDEO 5w20 for a 34k mile OCI in a pentastar. Oxidation over ****** was 27.1. Viscosity had thickened quite abit though up to 13.2@100c

No soot for diesels either.


So, tonight I'm working my spring machinery maintenance list and realize I need to change gear oils on the UTV. It takes a straight API GL-4 (no EP additive), I imagine for the shift lockup synchros inside the gear boxes since there's no transfer case. These aren't spiral bevel or hypoid either, just plain 'ol bevel gears.

I usually get Red Line MT-85 for such things. Holy moly it's $23.10 per QUART everywhere! wtf is going on? Other syn GL-4's look to be charging similar, AC Delco, etc.

This simple oil should cost less than an engine oil, with all the additives needed for engines.

As for me, I've always been a Mobil 1 guy, though I haven't had my first oil change yet. I'm reading about this Amsoil oil, is it batter for a 5.7?
