Additives Settling out of oil

[TimeFlies]

True, but it puts the precipitate back into temporary suspension and operating heat can put it back into solution.

Good info, thanks.

Same here. Whatever it is, it does look like it's kinda stuck to the bottom. I mean, I let my jugs drip upside down for a couple hours sometimes and there's still some there. Maybe this vital oil sap of life is what we should be sending to the lab.

Actually that would be interesting.

I'll still be shaking the oil jugs I use from now till I die I'm sure.

I weighed it out last time when I was using 1qt bottles. I thought surely there's a lot that clings. I left each bottle in the funnel for a couple minutes then capped them and left them upside down overnight. I poured what had gathered in the cap and re-weighed. The oil was 815g/qt and I only got an average of 6g/cap. So ~0.7% was left clinging. If your fill is 6qt that means you'd miss out on 1.3oz to cling. I slept better that night.

PP is the only oil where I have seen stuff in the jug - might just be the yellow plastic contrast - but that got me giving them all a shake - we are talking about minor PPM of the good stuff needed in that formulation …

I forgot I wrote it down. After getting what was in the cap the total weight poured out was 813g/815g so 2g of oil left behind. It might be all additive sediment but ah well.

Sounds about right. Nice time I do a change I'll do the same with the dregs and then compare the color vs a bottle that's been shaken, stirred, swirled, twirled, flipped, spun and twisted. In that order. You know, for science.

Chevron, as well as most others has a 5 year shelf life on most oils.

It's a chemical separation, mixing doesn't fix that.

Well, it is not so much as to the separation of the chemistry, but 1) the solids that were in suspension in the fluid may separate, and 2) some metallic elements may attach themselves to each other forming particulates.

During the blending process, the batch of base oils and additives is heated and mixed to form a fluid solution.

I always suggest bringing the containers in from the garage, shaking the container and placing it (them) over a register, and then shaking the container again before adding to the driveline component, which tends to duplicate the blending process.

I have a new video idea for Project Farm...

Please don't. We have seen enough junk info from PF.

Maybe Lake Speed Jr can do a third additive video.

Dunno, it's what the Chevron engineers taught us.

I'm by no means an expert, or even smart

Is there a point if you're pouring the whole container into the engine anyway, though? Because then the engine itself is going to heat and churn the oil upon startup.

The point is you're duplicating the blending process somewhat and getting everything back into solution.

You said you "always" suggest this. Do you mean for oil that's been been sitting for 5+ years, or even for oil that somebody bought yesterday? How quickly does everything fall out of solution?

Bought yesterday, doesn't tell you how long its sat around in warehouses, and stores.

I'm aware and was thinking of that as I was typing that, but obviously we don't know what answer to that. But at least the difference between purchased yesterday versus "purchased five years ago and sat in my garage" allows some type of dramatic difference to distinguish between either way.

Absolutely correct, just mentioning that it could still be old.
I was in a bulk plant warehouse a few months back, and there was oil in there that had been there several years already.

I've noticed quite a lot of black/brown gunk in the bottom of Mobil delvac extreme jugs the past couple times I've used it straight off the shelf from Walmart. I had a little extra left over and shook it good, got it mixed up, then a day later it was back at the bottom. So far the extreme is the only oil I have seen this happen too, Rotella t4, t5, t6 and delo sb were clean on the bottom of the jugs, no shaking required.

There are additives in many petroleum products. Back in the '60s I was working in the POL (Petroleum, Oil, and Lubricants) career field in the Air Force. In a sample of the 115/145 AvGas there was a colloidal suspension of a white substance in the fuel, which caused great consternation on our Air Base. Turned out the additive that made it purple was the cause.

We definitely rotate. FIFO.

Usually it's under a year old since "bottled".
