What would happen If someone were to use synthetic aircraft turbine oil in a car engine? I'm thinking It would blow it up.

 

Turbine oils are generally very low viscosity, and only lubricate in a very thin but cohesive (strong) film. The viscosity would probably be inadequate to fill the bearing spaces at the clearances of automotive engine bearings, possibly promoting rod and main bearing knocking. There would likely be a much greater tendency to leak, and it probably doesn't have the detergent properties of gasoline engine lubricants. I wouldn't risk it. I doubt that the engine would "blow up", but damage could occur to the mains, rods, and piston pins from sheared oil film and impulsive loads that aren't supposed to occur in turbines.

 

Thanks for the reply Vader!
I didnt think it would fly.

 

A little bit of personal experience to confirm what Vader said. A guy at work (I work in an aircraft engine overhaul facility) put Mobil 254 in his car. The results, to say the least were not pretty. The engine needed a new crank after one run to town and back about 20 miles @70 mph

 

Also the aircraft turbine oil (2380, 7808, etc) will eat the seals right out of your car. Seals on a jet engine are specially formulated to withstand that type of oil.

To the question yes I agree. I work on Helicopters that use turbine engine oil. Not for cars what so ever. A turbine doesn't have as many moving parts a car engine. Car engines have up and down movment. Aircraft engine with a circulor rotation.

 

Hey, F-1,

The next time you happen to run across a couple of spare 8,000 SHP Garret or Allison turbines just "lying around", let me know. I've got an idea for my S-truck....

 

LOL. I could use one of those bad boys also.

One more question since we have 32 quarts of this oil. I see no reason why it couldent be used as power steering fluid, can it be used as PS fluid??

 

It probably won't have the anti-foaming additive of PS oil. It certainly won't have the cling (parafin) of a way lubricant. It won't have the sulfur additives used in cutting oils. And if you were thinking of using it in an reciprocating air compressor, the results would be simlar to a gasoline engine. And forget about using it as hydraulic oil.

Can you return or exchange it? Got a chainsaw? (Bar/chain oil only.)

 

It was free. The shop at Ft. Carson doesent work with any of the M1's or Apache's anymore so they had a few boxes to dispose of. I do have a couple chainsaw's so It will get used one way or another.

Thanks!

 

E Bay it.
I wouldn't let it come in contact with any automotive type seals, it will eat through them in no time.
