Dont Mix Delo with Pennzoil 5w20

I purchase a virgin bottle of Pennzoil 5w20 today, I emptied it into a jar. The bottom of the bottle had a grey/black silt type material on the bottom. Very simular to the stuff found earlier but not as abundant.

None of my bottles had this stuff in the bottom. Just a bright Yellow fluid.

And was this stuff a metallic looking substance? Is it attracted by a magnet?

Hmmm, now if everyone went out and bought a bottle of or two of Pennzoil 5W20 to see what was in the bottom, sales might rise?

Like Pablo said, copy down the lot number and email or call Pennzoil.
 
Ah-ha! The solution is near. Can we say "bad batch"? Hmmm..who was asleep at the blender when they were supposed to be exercizing GMP and SPC??? Who signed off on the lot? What lab tech is going to tap dance when the boss hauls him/her in for sending out all this lame oil??

The suspence is killing me ..I hope it lasts...
 
I suppose anything can happen .... dunno I was not there but .

I have an open bottle of the 5w-20 here that set in the shed for almost two years and cap was not on that tight either but just poured it out into another container , nothing but oil and the ever so slight residue at the bottom seems that even M1 Supersyn has . Thats why I shake my bottles before pouring in .

And why some oils come in black bottles .

Am I correct in saying there is another thread about this engine ?

There is an engine here on the forum getting WATER in the oil . Block casting , head casting problem or other maybe but not an oil problem .
 
There must be two versions of Pennzoil 5w20 out there because
MolaKule said his was very light, Mine is dark. Looks like pancake surup.

Mine is dark too but was purchased a long time ago . Revisions are made periodicly . Ultra clear Motorcraft to light amber now ect .

I recommend having your cooling system pressured up . It will help here I believe .

Ever notice the pennzoil 5w20 is so dark.

Not the stuff I have. This Pennzoil is a light color, I would say in fact, Bright-Yellow to Yellow-Amber.


Pennzoil must have reformulated, then. The 5w20 I have is VERY dark. The last I bought was in the 5 qt jug, and I've got a full case of qt bottles. Both are very dark.

It would be interesting to do a VOA on the light 5w20 to see if they have taken out the moly.

I havent added a drop of coolant since I put the engine in. The level in the overflow hasnt dropped in 6,000 miles. Its not water

Maybe they define SPC like the company I work for? Ship Product Continuously.

Still no "settling-out" or any miscibility problems and it's been over two weeks.

Maybe Johnny from Pennzoil could commnet on earlier batches of the 5W20.
 
Well Just to recap, I changed the oil to Supertech 10w30 right after suspecting the oil as the problem, I put almost 2000 miles on it and decided to change the oil. There was almost no grey/black stuff anywhere in the oil or filter. I am running Havoline 5w30 for 3000 miles and only time will tell.
 
Borane readily reacts with acrylates, methacrylates, and any vinyl funtionality. I am sure the Borate Esters, and Boron compounds used in motor oils are very stable formulations, however, I do not know of this potential but hear me on this: For some reason some bad Boron compound synthesis, like I said I am not familiar with the Boron containg compounds themselves used in motor oils. However, organo-borane complexes can be decomplexed by acids, freeing Borane radicals, which can initiate polymerization of vinyl funtional materials. Just a thought as Boron can be a very reactive substance, and acrylates and methacrylates are used in motor oils. Could it be a bad Boron additive reacting with acrylate compounds? thoughts?
 
lobo thats a bit above me there

Pennzoil uses boron , the other oil don't .

Are saying something might be in the other oil causing a reaction with the boron and melting the plastic VII's ?
 
I seriously doubt the Boron reacted with anything else.

In my experience, if Boron interacts with something, it simply "clouds" the oil it's in; i.e., it stays in suspension, but clouds the solution.

I think there was some settling out of a dye or some other insoluble involved. I have seen old dyes (that have gone past "USE-BY") dates settle out.

In a high-speed bottling plant, it doesn't take long to fill a couple thousand quarts or gallon bottles with "un-planned" oil if the wrong valve is opened or mal-adjusted for even a short time.

Motorbike,

Don't really have a hypothesis, I just know that companies such as 3M, and Loctite (I think owned by Henkel now), Boron radical chemistry is sometimes used in acrylic adhesives for acrylic polymerization. I know many oils contain acrylates and methacrylates, so I was just throwing this out there. I would suspect like Molakule that if there was a reaction it would appear more like a precipitate in the oil, but I don't know. A lot of things can happen to chemical compounds as temp. increases and pH changes. I was a little surprised when I saw the new trend toward Boron compounds as Boron radicals are very reactive. But the whole issue is freeing Boron radicals to begin with, and I am sure this has been looked at in depth by oil companies.
