Crisco in your engine?

[G-MAN]

What would happen if say a bitter ex-husband changed the oil in his bitter ex-wife's Ford Windstar and all he did was pull the drain plug, drain the oil, replace the plug and then put in four quarts of plain ol' cooking oil from the grocery store?

Bitter ex-wife typically drives about 1000 miles a month and calls up bitter ex-husband about every four months about changing the oil.

(And before you jump to any conclusions, this story is NOT about me personally.)

I predict within a few weeks to a few months someone is going to court.

Maybe. I'm just curious about what will happen to an engine running on vegitable cooking oil.

 

[Bret Chase]

if it was me, I'd be telling the bitter ex-wife to go fornicate with her self. oh wait.. I DID tell that to my bitter ex wife.

Oh, I think it'll get all sticky and gummy. When it comes into contact with the hot steel it'll smoke and stink. Then it'll burn on, turn thick and black and really nasty in there. Plug up the little holes.

I'm speculating...I used to work at McDonalds, had to filter and change the cooking oils. For a long while we used solid shortening then they switched to liquid. Cut down on the fires.

I think cooking oil has a pretty lame flashpoint...so wouldn't it catch on fire?

 

[Pablo]

Think pretty much about the words used in those 1980's Castrol ads. They verbally would describe what would happen to the competitor's oil in a "high revving" engine.....break down and loud noise.

Then think about what you have learned here about boundary lubrication, EP, even FM's. Then think of the add pack in Crisco.

Crisco. It's what's for parties.

Crisco. Have you fried your engine today?

A lot of people running vegetable oil as fuel have ended up with a sump full of vegetable oil.

It's hot, aerated, and exposed to air/gasses.

It polymerises, and forms a rubber sump impression.

(Linoleum was manufactured out of linseed oil using a similar process)

I think the average deep fryer operates at something like 400F, and you'll never see sump temps that high in an engine. I don't think cooking oil in the sump is going to smoke, burn, or catch fire.

Let us know how this all works out. See if you can get a sample for UOA.

Yup. I work in sawmills and we use canola oil for lubricant on the saws. I have tried to light the stuff with a cutting torch, it never would burn. Just smelled like french fries. Castor oil was used in early aircraft engines because it wouldn't congeal at the cold temperatures encountered at high altitude. I suspect that no one would notice the oil switch unless she does some high-speed, long distance driving. It will definitely shorten the life of the engine but you may not notice for a while.

basic seed oil soy or even canola have a flash pt >500F more like 580F as I remember.
They will lube like crazy till they oxidize then will thicken to semi solid at that time motor will sieze and your "buddy" should not speak without a lawyer present.

Bitter ex-wife should be finding a reputable garage. She's just asking for a showdown the way it is now. But then maybe that's the point?

Peanut oil will freeze at relatively high temperatures. I have some in the fridge and it's solid, looks like lard. I mention this purely as a point of scientific curiosity, of course.

 

[UncleS2]

Don't put Crisco oil in that engine!

For goodness sake- everyone knows you should only use Wesson Oil!

Bitter ex-husband could truthfully inform bitter ex-wife that he used a 100% ester-based product with no toxic additives and fit for human consumption.

 

[Mr. Boston]

Bitter ex-husband is only looking out for the best interest of bitter ex-wife by supplying her with all organic supplements.

 

[ToyotaNSaturn]

Since this is a Windstar, I assume that coolant will leak into the Criso. What a mess that would be.

Any takers will to to figure out what the chemical composition of this muck would be after 4000 miles?

As long as you don't use the 5-20 Crisco, you'll be OK 8,)
