Status: offline 		I know it has been discussed here before and I believe downunder uses it in his fuel.
I have aquired some Mobil Jet Oil II jet turbine oil and wonder if it will be sufficient to use in a fuel mixture ???
I was surprised that it came in a can, and on the back it says to avoid spilling on insulation, plastic, rubber or paint.
I haven't been to their website to do any reading up on it, I thought I would post here first to get a discussion going.

I think he wants to use it in glow-fuel.

If that's the case, some is okay, some is not I'm thinking that the newer (version 2) oil has problems.

Also be aware that this stuff can have some pretty toxic combustion byproducts and I believe it also stains film/paint.

A better option would be the DTE Lite turbine oil. I think it's an Ester-based biodegradable turbine oil that should mix with methanol (but you'd need to confirm that).

Status: offline 		Yep...looks exactly like the cans I had. I know that there's a generation 3 version which won't mix with methanol but never having seen those cans I can't say how they might be marked. This oil is the only one used in Australian military turbines and we didn't skimp on oil quality . It can stain certain finishes because of the heavy brown dye used in it but an alternative is BP2380 which is almost clear. It's specifications are a little lower than the Mobil but not enough to bother about for model use. Combustion byproducts aren't anything to worry about because...well...it's an oil and stays an oil . One aircraft I worked on (the Jindivik target drone) used a total loss oil system so all oil went into the tailpipe and got burned. However thus dint afect us att alll.

Status: offline 		Thank you for the replies.
So even though it says on the can that to avoid spilling it on plastic and rubber it didn't harm the fuel tank and fuel lines ? I wonder why those warnings are on there.
When you mixed it with the methanol,did you use an empty glow fuel jug to put it in? What percentage oil did you use. And do you pour the oil in first or the methanol?
Also, if you didnt use a whole can of oil when you made the fuel, how did you store the oil that was left in the can since there is no way to reseal the can ?

Sorry for all the questions, these are just things I am coming up with that I haven't found the answers to.

It's a carcinogen so you want to avoid spilling it on anything, on plastics it will stain them, they'll darken considerably with continued use.

Status: offline 		I had no problem with the jet oil other than it turned my plastic squeeze bottle (I fill the old fashioned way ) a dark brown but it didn't affect the fuel tank or lines. If you read the MSDS on it you'll find it's not carcinogenic and is quite safe to handle but I wouldn't advise drinking it .

I mixed 17% jet oil with methanol and no nitro. I just poured the right amount in a container, topped up with methanol, gave it a good shake and went flying. The can with the remaining oil was just covered with cling wrap plastic to stop dust getting in but you could always pour it into a clean screw top jar or whatever. For interest's sake, I found this oil to be ideal for lubricating the plain bearings in my Myford ML7 lathe as well (drip feed).

How much of the fuel did you mix up at once?

I will try that too
My wife brought me home some castor from the drugstore the other day and I mixed up a small batch and after a couple of days I could see some separation. Maybe I didnt mix it well enough. I know that is not the castor to use but I wanted to try it and see what happened.

Status: offline 		Maybe things work differently down in Oz but here in the northern hemisphere in the south eastern US synthetic turbine oil stains the lines and the tanks. the lines on my fueling jug are replaced once a year, these are less then 6 months old, the startup/taxi tank is about 1 yr old and well stained too.

Status: offline 		When the lines are darkened like that, do they turn hard ? What does the carb and the inside of the muffler look like?
Also, what % of oil are you running?

the lines do get hard and brittle that's why i replace them at least every other year on the aircraft and yearly on the fuel jug, i don't run turbine oil in anything but my turbines so there are no carbs or muffler but the fuel needles are clean and spotless after 25 hrs of run time, tail cone and pipe are as well. we only run 5% oil in our fuel, at 17% with methanol I'd guess the staining would be much worse.

Status: offline 		KC, what kind of fuel do you run your turbines on?

I just mixed up a 1000ml batch of fuel with 15% oil to see what would happen. I really didn't even have to shake it much to mix it so when I come home from work tomorrow we will see if it is still mixed.
I just put it in a clean glass container for now.
