RE: Turbine oil other than Aeroshell 500?
Is Milspec the only consideration?........what about thermal stability((the ability to resist bulk oxidation of the oil, which leads to coking))......it's that which separates first from fourth generation turbine synthetics, as well as cheap bulk motor oil from top line synthetic automobile motor oils......as well as other variables such as pour performance at low temps.......even though they all have the same Milspec.....
How does Milspec apply to our unorthodox use of turbine oils in the first place, i.e. mixing it with kero??.......there never has been a Milspec in that regard published that I am aware of......Does anyone know how bulk oxidation is evaluated during Milspec testing?....I don't.....is it even tested while mixing the oil with gasoline or kerosene??
AMT USA makes note on their website not to use 2380.....Why?.....I've been told it is because of excessive carbon deposits......what data have they based their decision on?.....is it anecdotal or based on a controlled study comparing identical engines, under identical operating conditions, comparing 2 or more oils, with both the operators and inspectors not aware of which oil was used in a particular engine....so called double-blind study.....or did Aeroshell give them a hell of a deal on some 500/560....just kidding!
So for me, as new third and fourth generation synthetic turbine oils have appeared, I have used them, hoping for better bulk oxidation characteristics and therefor less carbonizing in the combustor......but mindful of the fact that I have no solid data to support that decision.....just trying to make a logical choice based upon manufacturer-supplied performance data....

tom
those are good points
we mix the oil and jet-a together
we are using it like a 2 stroke oil
i dont know if and any the tests
the oil companys do use it
the way we use it

do you know if the Castrol 5000 Gas Turbine Oil Type 2 meets the mil spec. # 23699?

I have been having difficulty finding Aeroshell 500 locally. I don't know if that is what started this thread, but here is a supplier I found that did a great job. They had a case of oil to me in less than 7 days from an internet order.

Hi, I also had a problem with Finding Aeroshell 500 Locally. I use the www.oil-store.com for my turbine oil needs. The nice thing about them is that you can buy it by the quart if you want. $8.09 I find that 3 to 4 quarts at a time is good for me and that way I don't store it in the winter months.

RE: Turbine oil other than Aeroshell 500?
hi. ive bought some aeroshell 500 second hand and the date stamped on the top of the tin says 2006.
is this a use by date or manufacture date? can it be used?
thanks

typically it's date of MFG, as long as the cans haven't been opened they are safe to use, they may be a little darker in color but once mixed you won't be able to tell the difference.

The last time I bought oil I bought it from Bob Wilcox at jetcatusa.com. He claims it's less toxic and has antistat mixed in. I think it was $10 quart.

RE: Turbine oil other than Aeroshell 500?
I just acquired 100 quarts of turbo oil, it is a mix of Exxon 2389, Exxon TJ-15 and Exxon 25, the price was right (free)
Any idea if it is ok to use in my jet cats
Thanks Kerry

RE: Turbine oil other than Aeroshell 500?
Several other manufacturers are nowadays recommending the use of 2T synthetic oils that comply with the JASO FC or FD norm. Can this oils be used with Jetcat turbines ? Part of the reasoning is that these oils are specially formulated for being burned and not recirculated like what happens with turbine oils.
