Mixing/shaking oil

[buck91]

I have always been a believer in giving oil a quick shake before filling and engine. Never sure it did much but figured it doesn't hurt. After all, you mix paint, you mix many rattle cans, etc. Well today I think I may have justified this a little bit. Changed the oil in my truck with PPHM 5w30 and gave the first jug (takes 7-8qts so I usually buy two 5qt jugs) a quick shake up without much enthusiasm or effort. After emptying into the truck, I looked into the jug and saw the picture below. Gave the second jug a much more thorough shake and I was able to visualize about half the bottom after filling up (due to remaining 2-3 qts of fluid). Sorry no pics of the second jug as both hands were occupied, but you'll have to trust me that no similar deposits were noted.... Thoughts?

I'm just happy I barely ever use Pennzoil

Haven't seen this from any other oil brand.

I have, brands include Mobil, Castrol, Havoline, Pennzoil, to name a few. This horse has been beaten to death almost as much as the thick vs. thin oil discussions. Or the 5W20 vs. 5W30 wars.

Some additive packs will do that, i notice that with Mobil 1 afe

Then you're either new to oil or haven't really been checking.

It has been mentioned many times that the yellow jugs show the fallout quite clearly compared to gray or white jugs.

Yeah, the PP 5w30 I put in the Camry I heated the leftover oil in bottom of jug and sediment. I heated it in old pan and the "stuff" was blended in in like 8 minutes. Nothing to worry about

Looks like precipitation of one or more additives. Not sure if shaking will prevent this but it couldn't hurt... I shake my supplies every few months (including coolant, gear oils and transmission fluids). Generally, shelf life of oil in sealed containers is about 5 years.

Waste of time shaking if you're just gonna let whatever fluid sit on the shelf. Just shake before using, no ?

I'd always wondered if it's either moly or unfiltered byproducts. I've also seen it in almost every oil brand I've used except Quaker State.

I've seen this a lot over the years across all brands I have used. Some more than others. It's nothing to worry about. A good shaking is the right thing to do.

A lot of documentation exists that oil is "dirtier" going into an engine than the oil that is drained out (going PURELY from the micron size of particles before being run, and after being run through the full-flow filter a million times)

 

[Zee09]

This has been noted here often as said.
I changed oil today. Used 4-5 year old Kendall FS 5w20.
No shake, nothing in the bottom either. Good for me

Depends, rather obviously, on what it is.

IF its additive precipitate, you probably want it, assuming additive precipitate isn't abrasive.

IF its dirt (covers a lot of materials) then you probably don't want it, since you can assume most dirt is abrasive.

Looking at that picture, to assume that was additive precipitate I'd have to be an optimist.

I'm not.

I shake my oil since this topic came up several months ago. It can't hurt. There's a James Bond joke in here somewhere.

Like I explained in the post just above yours, it can hurt, and my bet is that in this case, it did hurt, because that stuff looks like rust, which doesn't provide even a Quantum of Solace to your average engine.

I give all fluids, e.g., oil, coolant, power steering fluid, etc., before filling.

I've seen it in Kendall GT1 containers also. It very common.
