Jet Turbo oil-can it be used?

[Patmac]

Okay- it's a bizzare question, but one of the customers at work (we handle freight for several airlines) dropped us a few months ago. We have been cleaning things up and found 2 cases of Jet turbo oil they were storing with us. Obviously there are no normal viscosity numbers like we are used to on the cans, but can anybody with real knowledge tell me if it could be used in an auto? Without opening a can, it seems to me it would have to be a light oil to flow with the tight tolerances of a jet engine. Maybe it might not work in our diesel engines, but I still have a rice-burner and an old CJ7 that still need oil changes. Maybe an A&P mech can clear the haze?

I can't lay my hands on it right now, but I read an article which warned against this very thing. Turbine oil and recip oil are night and day different.

Mobil Jet II/MIL-PRF-23699 is the most common used Jet Engine oil on the market. It has a centiStoke rating of around 5cS. That makes it approximately a SAE Weight of 10. When it is at operating temperature, it literally flows like water.

Almost all of the bearings in a jet engine are are roller bearing. Ball bearings are used also, but the predominate bearings are roller bearings.

Do NOT use it! It does NOT have the ADDITIVES needed for your Diesel!

Thanks guys- I knew I would get the answer here- I'll see if I can talk to one of the jet mechs that works on the flights to see if they can use it-

you can burn it . mix it right in there with the number 2

Thats what I would do! I would not recommend going over 25% oil in with the #2 especially during the cold time of the year. At 25% you probably won't even notice a difference. I have done this with Hydraulic oil, which is pretty much the same.

No way!

I'm a Jet Engine Mechanic and I've been using this stuff for 25 years now, and I can tell you first hand that you will only get about five miles down the road before the engine melts down on you. A few years back one of the guys in the shop tried it in his gasser... needed a new engine a few minutes later.

Thats awesome... I LOVE hearing about people that try something like that WITHOUT doing any research first...



We have a young guy that works at our shop that attempted to run "well drip" (distilate) in his late model Toyota... This can be done, and usually on older carbureted engines, and in a blended formula. .

This genius just basically topped his tank off with the stuff on a F. I. Toyota. .

Rumor has it, the first signs of something going wrong was the engine idling at 3000 RPM. He ALMOST made it to town before it welded itself up.

About 40 years ago... ... . An older friend of mine got a 5 gallon jug of 30wt MOTOR oil. He had a 1957 Chevrolet, Belaire, 2 door, Black on Black, with a factory dual QUAD 327 or 283 (I am lucky to remember this much!!) and a 3 in the tree. (He had ordered it NEW in '57) Well... . The oil was just as I said it was..... 30wt. ELECTRIC motor oil. Needless to say, His engine lasted about a few days and started knocking.

On a side note, I met him when I was about 15yrs old. When I got my license, He came by, raised the hood and hooked up the other quad and he let me drive it! Nothing like the sound of a small block Chevy and a couple of Rochester Quads WIDE OPEN!

when i was working on jet engines, another employee used some of the lube oil in his car. he said it started and ran great. but after a few miles his oil pressure dropped. he stopped and checked out his engine. the oil seals had pretty much dissolved. oil was leaking from both ends of the engine. also the oil is a synthetic, so it won't burn worth a darn. it is designed for very high operating temperatures. i can't remember the flash point, but i'm sure it was over 1800'f.

just a precautionary note, so you can make a educated decision.

Don't do it!!

Do Not Use it in your truck ANYWHERE!!! Mil-PRF-23699, BP 2380, Turbo 25, & other oils of its type are designed to lubricate Gas Turbine Engines, & certain Helicopter gearboxes only!! The stuff is very thin and has a high flash point, so it won't carry recipitating style bearing loads and it won't burn in the cylinders well either. Now, if you can score some Jet A or JP-8, that's another story! That stuff burns well in pre 07. 5 engines. To much Sulfur for 07. 5s and newer, though. Add some two stroke oil for a VP44 24 Valve truck!

That ^ is correct info. You can put some in the tank, but it won't be beneficial; it doesn't combust efficiently. Definitely don't put it in the crank case. I think the best use of it is with the turbine mechanics you know.

 

[Patmac]

Just to let y'all know..... the oil is currently doing service in some Delta jet engines out of SEA-TAC right now... .



That was some very interesting reading, by the by- thanks again everybody
