Could you arrange to have the Canadian dealers sell Kingtech Oil?

Thanks

Dirk

I am using BP2380 now and is this acceptable in both of my Kingtech turbines?

Using BP2197 as only thing I can get my hands on.

Hi, BP2380 is a good oil for KT engines, no detrimental results reported, we are currently looking into Canadian dealership to carry KT oil.

Great to hear. I would rather use the KingTech if possible.

Here we have yet another turbine in for bearing failure. I appreciate the honesty of our customer in stating he was running 2 stroke oil and switched to a turbine oil after he started hearing noises. His failure occurred at 842 minutes. As it may seem that the turbine is running fine with 2 stroke oil, it does take some time for the failure to show itself. This particular turbine took me over 4 hrs, just to clean the baked on crud off the turbine wheel, NGV and out of the chamber and that's after it soaked in my parts cleaning tank for 2 days. Do your turbine a favor as well as your wallet, STOP USING 2 STROKE OIL!! It will give you a better, longer flying season...

Jeez, 2 stroke oil is hell in turbines it seems.

Dirk (you're in my home town of Fontucky!) what and how is your Kingtech oil made? Is it a mixture of different oils out there?

I have probably 8 quarts of Aeroshell 500 that I'm going to continue to use in my varied fleet (3 jetcats, 1 kingtech and 1 B300F) and then I'm going to switch to some other type of oil.

1st and foremost, the oil has to be EASY to acquire and then be cross compatible to ALL my turbines.

Rav Aeroshell 500 is very bad for kingtechs. It really gums up the bearings bad.

Rav,

If you look back to page 1, post #18, there are some pictures posted of bearings using Aeroshell 500. You can use your own judgment to finish off the oil you have in your KingTech but I strongly advise you not to. I have had turbines in with as little as 30 minutes run time using Aeroshell 500 and it looked like a 30hr turbine, and I am not exaggerating this statement. Barry is our expert when it comes to oil as it is his blend that is performing superbly so I would contact him for specs and questions. I know our oil is shipped anywhere in the continental US, 2 gallons for $90.00 shipped. I don't think you will find any other turbine oil for less unless you get it free at work.

Good flying,

Dirk

Can I use a Shell Tellus 32 / BP 2380 / Aeroshell 560 in my K100G if I can get them easily in here in India.

Sorry for the late reply, just saw this thread, please stay with BP2380, even Tellus 32 along is better than Aeroshell 560.

Cheers,
Barry

Default Turbine oil

Don't know how many times I have read that 2 stroke is no good for bearing but NOT ONCE have I ever read type of 2 stroke oil. All of it has been branded under 2t ..... My point being that there are at least 3 types of 2 stroke oil. Standard petroleum, synthetic and standard oil mix and then the latest 2 stroke being pure synthetic with much higher heat ratings. Would be nice to see just which 2t lubes are causing the issues.

Stegl,

It seems to me Amsoil seemed to be the 2 stroke oil of choice that failed horribly. The best Amsoil I found has a flash point of 88*C or 191*F as I am sure most other 2 stroke oils do as well. I'm sure if you look real hard you will find some 2 stroke oils that have a higher flash point in the 400*F range but that is still a far cry from our operating idle temps. Most turbines idle at 400-500*C or 750*F to 930*F and are upwards of 700-800*C or 1450*F at full throttle. 2 Stroke oil has very little chance to properly lubricate before it is evaporated and burnt up. I have had many failed turbines that were running 2 stroke oil, whether it was petroleum, full synthetic or a blend. Let me put this ball in your court as I don't have the time or need to research this subject anymore. Please find a 2 stroke oil that has the flash point that can handle our type of temperatures and I will happily warranty your turbine if you choose to test it out. Please submit the Brand of 2 stroke oil, model / spec # and specs for pre approval. If you choose to run a 2 stroke oil on your own, please keep in mind your warranty with any Kingtech turbine will be void. Please look back in the thread at the pictures posted of turbines ran with 2 stroke oil. All of them are a dead give a way they ran 2 stroke oil, see the ash white or green parts.
If you find an oil you want to test, the turbine will need to be new or under 1 hr run time, to give a fair evaluation. Some 2 stroke oils made it to 8hrs before complete bearing failure.

Best regards,

Dirk

Hi dirk : I think that you may have misread my thread. the point I was trying to make about all the statement's said in the past several years is that at no time was there any differentiating of the type of 2T oil being used ; was it pure petroleum , semi synthetic or fully synthetic as there is a fare cry from the first to the third in specs. Regular 2T oil will coke up the bearings real fast , the semi not quite so fast and the fully synthetic may work on some brands subject to specs. Myself , I don't use it al all as bearings will get sticky . I use DTE in my brand of turbines. Again, the point I was making is all three got lumped in together . As for Amsoil use , they again make about 3 or more types of 2T oils with varying lube specs. Myself won't use Amsoil. Thanks for the reply.

Have you guys tried TCW3 oil? Been using it for 2 years (on jetcat and jetcentrals with diesel fuel). Seems to work just fine. Other folks in Canada and Europe have been using it for years with no "side effects".

And yet Jets Munt specifically state ; not to use TCW3 oil in their turbines as this was set up for marine 2 stroke use as it is not poisonous to aquatic life; so unused out the exhaust must dissolve in water so if it absorbs water then that could create rust in bearings.... ? No ?

Aside from the coking problem associated with two stroke oil, TCW3 is incompatible to the sealant we had and will cause fuel leak, a potential fire hazard.

No argument there at all... just reinforces my statement that there are many many types and brands of 2 stroke oil out there yet in this forum people continue to lump everything (all brands and types) into " 2 stroke oil " as if there is only one 2 stroke oil. In any case I don't use it.
