Oil additive fall out

[Texas Diesel]

This is 90W gear lube that has been sitting for a year. All the stuff we pay for is laying on the bottom as sediment. I have seen this with several brands of gear lube, also seen it in one quart motor oil bottles ( RotellaT is the worst) and in Texaco MTX 5 gallon pails.



Perhaps I need to stir the bottom with a paint stirer



Anyone else seen this? How did you mix it up?

Like I was told in chemistry class: If you are not part of the solution, then you are part of the precipitate!

That's why Chevron at least dates their containers, says to rotate stock and to use within one year. My local Chevron jobber has one week in Nov with no stock, everything gets sent back and replaced with new.



Try stirring it up with a paint stirrer on a power drill. Probably don't want to aerate it though.

Many years ago in a place far far away (30 miles at least) I checked the oil before taking the runabout (460ci gas) out on the lake. It was a tad low and we always ran it a tad high to avoid starvation while doing boaty-wakey manuvers. So I grabbed the nearest quart of motor oil and proceeded to pour it (this is going somewhere) right at the end of the pour a black sludge came out. Obviously precipitate. I didn't worry too much about it. I just thought to heck with QS oils. I didn't get 1 minute of 3/4 throttle (after clearing the NO WAKE) before she sputtered and seized up.



I don't KNOW that something else didn't cause the problem, we sold the boat with bad motor. It was just too much of a coinky-dink (Kelly Bundy) for me.



So I'm doubly cautious of "aged" oils now and never go near a QS product.
