Default turbine oil and fuel



AT the moment i am using mobile jet 2 turbine oil,but in the uk its starting to cost alot to fly.
19litres of parafin is £18.96 plust 1 us quart of oil what is about £8.50 = £27.46 for 20 litres of fuel ready to use.
20 litre of fuel at 3 litres per a flight is about £4 pound per a flight.give or takea few pence.
So my question iswhat other oil and fuel can we use with outrisking the turbine,as i understandthe cost of a new turbine will out way the few pound i can save but people must beflying with other fuel and oil .
thanks for any info.

I've just bought some Mobil DTE light oil to try. It is approved by a lot of the manufacturers (although I'm not sure about Jetcat). The only problem is that it only comes in 20l containers but it is less than half the price of 'turbine' oils.

I've been using Mobil DTE Light for several years. Wren approves its use in their engines. It is used in some full-size gas turbines that are ground based e.g. power generation, as they don't need the additives for very high altitude flight and neither do we. I believe it is also free from the very harmful organophosphates that aero turbine oil contains. Without carriage it comes to about £4/litre. Since it only comes in 20 litre container, share it with some other jet fliers.

Darrell,

I'm not sure where you are in the UK, however, find out where your local airfield is and wether they sell Jet A1. You'll typically pay 65-70p litre. They'll probably sell oil too - usually around £8 litre.

Cheers

Hello Guys,
Do someone of you know if we can change the 2380 by the mobil one without any gum effect on canister, UAT, fuel pump or tanks ?

Best Regards,
Rick.

I changed from 2380 to DTE Lite a couple of years ago without issue. My turbines and related items are still very happy. [8D]

Dispensing from the large Mobil jug can be an issue (spillage if not careful) - I got one of these [link=http://www.globalscientificsupply.com/c/274/118500000_Dispensing_Jug_5Gal_.html]Dispensing Jugs[/link] and it works perfectly: no muss, no fuss.

All of my Wrens have been on Mobil DTE since new, 3% mix, that's not a typing error that is three % not 5%, the oldest now has 49 hours on the clock and is still on original bearings. The Mobil DTE light oil is just fine.

In the USA both McMaster-Carr and Grainger carry DTE Lite in gallon jugs. I plan on switching as soon as my last few quarts of turbine oil are used up.

Default RE: turbine oil and fuel

Early last year i did some research..you can do the same with wikipedia....http://en.wikipedia.org/wiki/Flash_point
the properties of diesel vs jet A vs kerosene....after that i started using diesel in my engines...jet central as well as an older Artes, in combination with that I used penzoil marinbe 2 cycle outboard engine oil 1qt per 10 gallons. Been doing this over a year with no problems..before anyone asks about soot and carbon buildup in the combustion chamber I will address that; soot= carbon monoxide which is a product of an incomplete combustion 2CH4(g) + 3O2(g) -2CO(g) + 4H2O(l) while a complete combustion CH4 + 2O2 → CO2 + 2H2O + energy yeilds carbon dioxide a colorless gas...the only diff to the two is the amount of oxygen involved. In our engines there is an abundanve of air as most of it is actually used for cooling..for those who would like to test this fact take a small container one with diesel and one with jet A and ignite them..you will notice that they both burn sooty black...as for the bearings ..i wont get technical just see the fact that many european companies already use this oil in there engines and ALL the bearings are the same from engine to engine..Diesel is slightly denser than Jet A due to some sulfur bonds and when these bonds break a higher amount of heat energy is released (see btu results for the two) when you first switch your ecu will remember the last pump voltage and as such will spin a little faster and then subsiquently recalibrate to a lower pump voltage and flow rate with the max rpm..I dont have thrust figures yet but i would assume them to be the same and def not lower...I welcome anyone to reproduce my findings...the convenience of going to a pump to get fuel/oil is awesome...

Which # DTE are you using ?

Here is a quote from Mobil's website:

"Mobil DTE 832 and 846 are superior performance turbine oils designed for use in steam turbines, gas turbines and combined cycle gas turbine (CCGT) applications under the most severe operating conditions."

Neither of those. It is Mobil DTE Light, from the "DTE Named Series"

Hello,

We have ordered a 3 this amount of oil for a 200L, it works without problems in our turbines, frankturbines, gbooster, jetcat.

Hi all, I have read a lot of threads on this subject, David Gladwin put a thread on the JMA Forum warning of the dangers of using Turbine oil, the main people affected being those that work in the aviation industry, not just your Sunday jet jock.

But I believe warnings should be heeded, and once I've exhausted my small stock of turbine oil, will change over to DTE Lite, OK, so you have to buy a 20ltr drum, well that's not a lot if you share it between four of five club mates, which in our club, (Bickley, Kent, UK) we have quite a few jet flyers.

As regards fuel, I have heard of people using Diesel and heating oil to run their turbines, which is virtually the same as Kero/Jet A1/Paraffin, If do a Google search, or Wikipedia, It explains the difference between these fuels, which is mainly the way it is refined, but by using good filtration whilst decanting should make sure the fuel is clean.

Many jet flyers in the UK now use these other fuels as the price of Paraffin is now so expensive, and as suggested, a chat to a local airfield could get you flying a bit more economically.

Hi
I started to use DTE Light a while now and am using it in Sim jets Wren's and Jet cat I had to buy it in a 20 liter drum and gave 80stg for the drum witch is a lot of oil for 80 quid and I have been using heating oil Kero for the last 5 years and had no problem what so ever, I used to use Jet A 1 but the smell but me off !

Haven't heard about mixing petrol/gasoline in with the diesel, need some input from people using diesel in their turbines as to how it is used, neat or otherwise?

just get heating Kero and use a "Mister funel " to filter it this is a better option as diesel has a lot of sulphar wich is bad news[:@] for most turbines
