'Yeah, it would be good to find out what you have.
There are different types of refrigerant oils. Depending on the system it was to be used in (If I remember right, it depends on the refrigerant itself), there are different formulations of the oils. Some absorb water like brake fluid does to try and protect the system. You might also need to know if the stuff has been sealed up so as to prevent acid formation from absorbing water.
If you can find out what kind of system it came from, we should be able to tell you what it is.....

'The refrigerant oil is basically mineral oil with additives. Here is a link to some typical refrigerant oil specs. http://209.85.173.132/search?q=cache...lient=safari . The flash point is close to that of regular motor oil (190 celsius=374 F). I could'nt get a for sure answer on using it as a fuel. One thing I might be a bit worried about is it deteriorating your rubber fuel lines. '

chuck d told me this stuff came from one of them big a/c units on the roof of a bakery

wondering if i should mix some with diesel to run in the isuzu??????? dont want to cause problems.

i've had cubbies of this stuff sitting around for a couple years.

Hmmm... There is a few things to think about...

1. What will the chemical do to the ignition point of the fuel?
2. What kind of deposits will occur after burning this?
3. What about the ash content of the oil?

:humm: I'll check a can at work tomorrow to see what it has going on with it to see if it might work.

awesome :U:

On the old 6.2 you could pour some Milwaukee's Best in the tank and it'd probably run.

it sure did good in the war months with 75% veggie. :U:

i havent had a chance to try any in the 1.8 isuzu yet. i'm hoping this a/c oil will prove safe.

I kept rereading this thread in attempt to find out if stuff if new or used. If "old" new stock, prob mineral as stated above. would consider useage only if it was kept sealed and airtight. I do not recall if it is hydrophilic (attracts water) or not.
If old "used," prob has some very small metal pieces in it. and would run it only after very good filtering ~5 micron. Remember, clearances inside injectors are very small and metal chunks are not welcome.

In any event, would not let it sit in tank or system for any length of time due to possible unknown side effects to innards.

If exposed to open air it will absorb moisture!

this is used stuff but looks clean. it has been in cubies for way over a year and in 50 gallon barrels before that and has been outside and now under a lean to shed.

i would imagine i need to be concerned about moisture though even though it has been in the clear plastic cubies with the lids on.
