Hi,
I am part way through building my Powercat with a Jetcat turbine. I see that Jetcat recommends BP 2380 turbine oil. Reading the spec it is to MIL-PRF 23699 which is a military spec? I have one tin of this BP oil and a tin of Mobil turbine oil which is to MIL-PRF23699F. Is there any difference? Can I use any turbine oil to MIL-PRF23699 with Jetcat?

I do not want to damage the engine.

Turbine oil
Richard JetCat used to recomend Shell 500 turbine oil, you will find that others will recomend differing kinds of oil, you will also hear the pros and cons of mineral, 2 stroke and synthetics, My advice as a multi JetCat owner is stay with what is recomended in your warrenty period, then see what's about, it appears that turbine oil is hydrolic oil with addatives, there will be turbine owners with more knowledge than me on the subject who will answer this post

AeroShell 500 is what JetCat emailed me 2 years ago to maintain warranty. Then a few guys I know use the AeroShell 560

Second Generation synthetic turbine engine oil
AeroShell Turbine Oil 500 is a 5 centistoke synthetic hindered ester oil incorporating additives to improve thermal and oxidational stability and also metal passivation
AeroShell Turbine Oil 500 was developed essentially to meet the requirements of Pratt & Whitney 521 B Type II and MIL -L-23699 specifications and is entirely suitable for all civil and military engines requiring this class of lubricant.
High Viscosity Index Synthetic Base Fluids used in AeroShell Turbine Oil 500 maintain viscosity and protect components more effectively under the high shear stresses that a turbine system places on lubricants.
The outstanding high temperature and oxidation stability of AeroShell Turbine Oil 500 is due to the natural properties of the synthetic hindered ester base fluids used. These fluids are clean running in that they tend to dissolve varnish and sludge rather than leave deposits on working surfaces.
Research and Development has enabled the most suitable selection of additive to be used in order to provide the excellent oxidation stability, superior load carrying and exceptional protection against high temperature corrosion of metals
AeroShell Turbine Oil 500 is also approved for use in the industrial and marine versions of certain aero-engines listed. The land and sea based derivatives of the aero-engines retain the essential design elements of their aviation versions. Such designs place heavy demands on the components and lubricants to ensure total reliability in the high temperatures within the engine. Engine manufacturers, therefore, approve the use of aircraft synthetic turbine oils in their engines.

Product Benefits

Outstanding high temperature and oxidation stability. o High Viscosity Index Synthetic Base Fluids maintain viscosity and protect components. o Qualified to MIL-L-23699, DERD 2499 and NATO O-156 fluid [ A qualified product must be blended and packed in the plant listed on the QPL to ensure that the base oil is made in an approved refinery and that the product is blended and packed in an approved and closely monitored facility.] which provides compatibility with other similarly qualified oils. o Excellent load carrying properties. o Good low volatility characteristics. o Resistance to high temperature corrosion of metals

Specifications and Approvals

o Pratt & Whitney JT3, JT4, JT9, JT12, PW 4000, PW 2000 o Pratt & Whitney Canada JT15, PT6, ST6, PW100 series, PW901 APU o General Electric CT58, CF6, CF700, CJ610, CJ805, CF34, CT7, CT64 o Lycoming T53, T55, AL5512, LTS101, LTP101 and all engines which specify MIL-L-23699 oil o Allison 250 series, 501D13, T56 o Garrett TFE 731, TPE 331-1 to -12 o Turbomeca Artouste, Larzac & other engines for which MIL-L-23699 oils are specified o Rolls-Royce RB183, RB211-22B, -524, -535, Tay, Gnome, Spey, Adour, M45H, Viper (Series MK301, 521, 522, 526, 535, 540, 601, 623 & 632.) Current status for Pegasus available on request. o IAE V2500 o Motorlet M601D, E & Z o Industrial Versions o Rolls-Royce Avon o Allison 501K & 570K Lycoming TF35 o Pratt & Whitney GG3/FT3, GG4/FT4, GG12/FT12 o General Electric LM100, 250, 350, 1500 & 2500 o Solar Saturn, Centaur, Mars engines o Turbomeca Industrial engines


AEROSHELL TURBINE OIL 560 is a new third generation “low coking” 5 centistoke synthetic lubricating oil designed specifically for gas turbine engines. This oil is blended from high quality “hindered” esters to produce the exceptional thermal stability needed in todays advanced engines. It incorporates advanced additive technology and a fine balance of additives to resist the high temperatures generated by turbine engines. These carefully selected components result in a product which greatly reduces the deposits caused by high temperature conditions and improves overall engine performance. Aeroshell Turbine Oil 560 offers significant performance benefits when compared to Type II fluids in high temperature bearing applications and under Ryder gear test conditions. Improved performance over previous approved Type II oils can be measured by cleaner engines and reduced scuffing in both bench tests and in operating engines.

Typical Applications Aeroshell Turbine Oil 560 is recommended for lubricant service in various types of aviation equipment. Especially in newer jet aircraft turbine engines, helicopter engines, and helicopter gear boxes where a synthetic oil like Aeroshell Turbine Oil 560 is approved by the manufacturer.

I forgot to mention Peter whales has been using Quicksilver oil and states" I have been using quicksilver 2 stroke oil in my turbines for the last 18 months with no problems. I buy it on line at $1.99 qt. It is apparently much much less toxic than turbine oil and I want to live a long time to play with my turbines years."

And when you think about what he is telling you, it does make alot of since.
There is no technical justification for using turbine oil in these engines. Turbine oil is designed for Full size engines which re-circulate their oil and have areas (sumps) which are subjected to elevated temperatures. On the model engines there are no "hot" areas when the engine is operating but only as soak back heating of the rear bearing after shutdown. The life of the bearings is not long enough to have coking as a problem. Use a good "air cooled" two stroke oil and use the extra money on fuel. --by Doug in Flordia

Turbine oil
Takes me back to my first post about turbine oil being hydrolic oil with addatives I know of another multi turbine owner who is using high V mineral hydrolic oil in his turbines, only time will tell if it is detrimental and his cost is a small percentage of what I pay for Shell 500 or the like

Thanks for the information everyone. I'll try and obtain a supplier of Aeroshell oil to use at least until the warrnty runs out.

Phil,
Sorry about that....misunderstood and, sorry about hi-jacking the post, however, an issue that could stand some further discussion.

Thats the stuff. 1 qt in 5 gals of paraffin, or 1 Litre in 20 liters if you prefer.

Some manufacturers want 2% others 5% and others 7% so I go with 5% for them all. I am not going to carry 20 gallons of different fuels around when i have 3 turbines on the same day.

I must admit, I took some convincing, but once converted I havent looked back

Hi,
I was running quicksilver in my wren, (three friends doing the same
with no problems).
I have just purchased a jakadofsky LE and was a little unsure of
what to use, but i trust your judgement peter!!
(Anyway you might have to test fly my turbine lama for me at the
next vario scale day!! pretty please )

Regards, Gareth...

Aeroshell Turbine Oil 560 - Qts

$10.19 Each 24/$206.69 ( this is what I use)


Aeroshell Turbine Oil 500 - Qts

$8.29 Each 24/$168.09

They ship from Western PA.

One of the many choices on the net.

Go to your local airport for the Jet A.

Bring your heli and show them what you are doing.

Some airports will not sell jet A to the consumer.

This will get you in the door.

Two-Stroke marine oil...
Just for the record... from a previous RR post also.

I use marine 2-stroke as previously stated and obviously missed by 'chopper jockey'/Phil/Hobby Parts (all the same...!)

QuickSilver marine synthetic.
Castrol Biolube 2T
...and for the guys in US as an additional option TT has an engine with over 100hrs on TORCO ski n' marine low smoke 2-stroke oil.

I use the same mix in all the turbines... 25ml added to 1litre.

The TORCO I used for many years with my marine 2-stroke racing engines and used to supply it in the UK.

Thanks
NEIL
