Oil gelling

[50yr Street Mech]

My personal opinion. After the 1st engine started pushing up daisies, I would not have returned to that drum again for an OCI. I would have went to Walmart, got the correct oil, do the OCI, then open a huge investigation on that drum on it's contents... I would have taken the pump off, and shove a stick down that drum and see what came back. My gamble is that something got in it. Have you used this same exact stuff in the past ?????....without any catastrophic failures ????....on the same engines ?????

I bought Mobil Delvac 1300 Super HD multigrade engine oil by the drum, to save money.

Who did you buy this drum of oil from?

 

[magneticanomaly]

From a local fuel and oil distributor....not a guy in a trenchcoat in an alley.

 

[Dutchy491]

Takes me several years to use it up.

Crazy situation for sure. Explain “several years” to us.
Maybe you’re into year 10 or something and the oil has settled the heavier ingredients to the bottom? I like to shake up the bottles before pouring the oil into my machinery. Kinda hard to do with a drum of oil I guess.

 

[50yr Street Mech]

Sorry to press, have you used this exact brand in the past ???? Seems like this is a " normal" way for you to do oil changes.

 

[magneticanomaly]

To Dutchy, could be 10 years. Is 10-year-old oil, apparently clear and of normal viscosity, on the edge of polymerization? Will sett;ling leave the supernatant ready to gel? I am trying to understand what has happened and why. I will buy new oil, But as long as I have no idea why "old" oil gelled, I will have no reason to think "new" oil won't.

Sorry 50yr, I do not understand your question.

I’m sure we have members here with their huge oil stashes that probably approach a 10 year mark being in storage. But they would have unopened and sealed containers, vs a drum, so it’s hard to tell.

I would reach out to the manufacturer.

 

[BMWTurboDzl]

Haha. Some good trolling going on here.

 

[50yr Street Mech]

Magnet, very simple question. Have you used this same exact oil in the past, in other drums of oil.

 

[Exhaustgases]

polymerization?

And is what multi grade oil is mostly made of polymers (jelly ). If it was not a multi grade you would not be having the issue.

 

[magneticanomaly]

50 yr, no, this is the only drum of Mobil Delvac 1300 Super I have ever bought and used.
Exhaust, yes, polymers are used to improve viscosity index by unfolding with increased temperature. But whether these particular polymer molecules are prone to linking up to form longer chains, or more prone than the base oil molecules, eventually long enough to approach solidity, I do not know.
I have spoken with Blackstone. Very pleasant and responsive, but do not seem to know about gelling, nor can they do anything with a gelled sample. I may send them a sample of the fresh oil.

 

[50yr Street Mech]

I don't know what to say, but stay away from that oil in you're vehicles. Put in whatever the oil cap tells you to use.

What fresh oil are you talking about? It sure as heck isn't the oil in that drum!

Type out a post like this, yet allows 3 engines to have oil-related issues?

This is too much.

I'm still not buying it.

What’s the date code on the drum. Attach a picture….

 

[Donald]

Trolling or ex-wife added something.

Unless your fleet or JiffyLube or Carnival Cruise lines I cannot see buying oil by the drum.

The new car you buy may require an oil different spec'ed than your drum and then what?

Rust Belt Pete's answer is very interesting, but there is no DEF (urea) anywhere around here. I think sabotage is also unlikely. I asked about water because some posters proposed it, and certainly moisture/humidity could have gotten into the drum as it breathed with temp variation, but the unused oil looks quite clear.

To 4WD, okay if you do not buy my story, can I interest you in a good price on some black jell-0? I guess "FF" means "factory fill". What does EHC mean?

I will look into Blackstone, thanks to TiGeo

Don’t single me out - several gave you the same - and waiting on tests …
EHC is base stock and dozens of big names buy it from XOM …

You might refrain from posting chemistry-based speculation when clearly you do not know.

It’s not “mostly made of polymers (jelly)”. Where did you learn this?
