Hello,
What will happen when 1quart of jet oil is mixed with engine oil?

 

Why would you?

 

Because I have 1 quart of jet oil for spare coming exp. date.
Just curious...^^

 

May not be compatible with synthetic? Might not mix. I also do not know the viscosity of the jet oil?

 

I wouldn't sweat the expiration date, when used for the supercharger. That date is likely more pertinent for use in FAA regulated aircraft. I certainly wouldn't use it, nor waste it, by mixing it in my engine oil.

 

For the cost of a quart of that stuff, you are going to risk your engine?

I'm wondering what other questionable life choices you have made....

 

I have mixed/used 100 octane aviation fuel (NOT Jet fuel) in vehicles and it's fine for high performance, costly tho. However I would NOT mix/use Mobil Jet oil in a car. Here is an explanation of applications and usage:

Applications

Mobil Jet Oil 254 is recommended for aircraft gas turbine engines of the turbo-jet, turbo-fan, turbo-prop, and turbo-shaft (helicopter) types used in commercial and military service. It is also suitable for aircraft-type gas turbine engines used in industrial or marine applications.Mobil Jet Oil 254 is approved against the High Thermal Stability (HTS) classification of U.S. Military Specification MIL-PRF-23699. It is also compatible with other synthetic gas turbine lubricants meeting MIL-PRF-23699. However, mixing with other products is not recommended because the blend would result in some loss of the superior performance characteristics of Mobil Jet Oil 254.Mobil Jet Oil 254 is completely compatible with all metals used in gas turbine construction, as well as with F Rubber (Viton A), H Rubber (Buna N), and other commonly used seal materials.
(All of the builder approvals are aircraft engine builders) Clearly this product is for aviation use only (Turbine engines)

 

...and superchargers.

 

You are correct! There is oil in the SLK32 supercharger and it is different and separate from the engine oil. Mobil Jet Oil is an approved supercharger oil for the SLK32.
The original question was the mixing of engine oil and Jet oil.

I found interesting video in Youtube.
I was surprised that it was already tested.
Anyway, jet oil keeps it's own property more than car engine oil at severe condition, but it seems that it does not make benefits in car engine.

 

Very informative, and the music wasn't bad either! Reminiscent of my Physics and Chemistry classes. (Bottom line: don't use Jet Oil in your vehicle)
