Re: Turbine Fuel (JETA1)

Comes in 20L pails with a pour spout at about $90 cad. Sure beats the US price at $36.95 usd for 3.78 L ( 1 US gal) from DreamWorks RC. That's quite a saving. You might be able to split it with some local guys.

Re: Turbine Fuel (JETA1)

Terrific Len, thanks for the contact #'s, I'll make some calls. Note sure I need bulk quantity as I can only burn so much in my garage, as the snows on the ground now, and the turbines are still on my test benches, won't be flying off those anytime soon.

Re: Turbine Fuel (JETA1)

Hey Charles: it is just on your back door step.... lol Got mine shipped in from the bulk
division of Esso/Mobil at Edmonton to Kelowna for FREE.... Not much free these days.
if you want a part number pm. still haven't told us what turbine you are using ?

Part number I have here I think is 104743 for Mobil DTE Light ISO 32 .The contact is Imperial Oil Calgary
toll free 1-800-268-3183 and was warehoused in Edmonton. Have the invoice around here somewhere
but can't find at the moment. This is the lubricants and specialties division.

Mobil DTE Light is a common lubricating oil used in steam and hydro turbine operation where a long lubricant service life is required.

Try 1-888-275-3776 and ask for Lisa Anderson is the other contact and that one could have been in Edmonton.

After googling a bit, seems the consensus is that I also need to switch/use Mobil DTE oil instead of the 560 that I have. Now just have to find it

Ah, the fun times of being new at something.... *insert-sarcasm*

Ron is correct about BTU's as well,

Side note:, I just had a 25 hour service on a JC Cheetah that has been fed the last 15+ hrs on diesel and mobil DTE light, they sent the old bearings back with the motor, I was surprised to see they looked brand new!

After running diesel for the last 3 years, I'd never go back to kero or Jet A.

Advantages of diesel:

more power
Cleaner burning
buy at corner gas station
cheap- 5gal diesel= $18, 5 gal Jet A= $30, 5 gal Kero (2x store bought 10L jugs)= $70

Disadvantages:
smokes at shut down (not really a big deal)
have to be careful with spills, seems to damage ashphalt tarmac more then JetA/ Kero

Hi Mike, thanks for your input on this discussion, its great to get feedback from all of the experienced flyers here. Definitely like the stats, it helps.
As I figured, seems each has there own experience with their preferred fuel of choice.

With Kero & Diesel being very easily & readily available, I thought I would try and source out JetA, but there has been some solid feedback on Kero & Diesel use now, so I'm getting more comfortable with those options.

Of course the reality of it all is that burning one or two tanks of any of the three options won't have any major affect on my nice shinny new turbine (well not that new, its been waiting to be turned over for quite some time now).

Ron, Thanks for the hook up, I'll definitely pick some up there and give it a go. I also got a suggestion to try Villeneuve Aviation Center for Jet fuel.

You still haven't said what turbine you are using...come on don't keep it secret ; tell us more.

I won't take it personally that you didn't read all of my very first reply to you, where the last line I humbly offer up what turbines I have. I'll spare you having to go all the way back to find it though.

I have 3 JetCat Turbines, 1x SPH-5 & 2x P20-SX..... all in the same model

just saying.

Re: Turbine Fuel (JETA1)

Here is a it of a scientific report of fuel in Micro turbines.... haven't all the way through yet.
http://scholarworks.wmich.edu/cgi/vi...=hilltopreview

This is a reply about a month ago I got from Wren power systems"
if using diesel in the Wren 44 TP try this mix :
10% petrol ( gasoline)
85% diesel
5% oil

The gasoline would be added to make it run hotter, I would think. A person could try straight diesel
and check the temp with the GSU and then use the gasoline mix and try getting temps with the GSU
again to see what if any temp changes.

I have read someplace of adding a small percentage of gasoline to Jet A or Kero in the winter time to help
in starting and running due colder air intake temps so there may be something to it.

Question on the Wren 44 non turbo; was that propane start or kero start ? Their own proprietary ECU or the newer V10 Xicoy ?[/QUOTE]

I know it's a propane start but, sorry I don't know which ECU, I can ask him.

He has it on a glider, it's pretty cool

Re: Turbine Fuel (JETA1)

I believe that Wren just recently ; ok'd the use of diesel in their motors but did say that
if it did not run well; to discontinue. Seems to what I have picked up is that a lot depends on the who and where diesel is processed.
There could have been a requirement to reset some of the ECU parameters, not 100% sure. Same with using Mobil DTE oil for lube.... Some manufacturers say don't use but then there are places that use it exclusively and no issues ie Australia for example , they seem to use what is available and it works.

Question on the Wren 44 non turbo; was that propane start or kero start ? Their own proprietary ECU or the newer V10 Xicoy ?

Just a note: http://www.rcuniverse.com/forum/wren...ld-diesel.html
Although the second link is pretty old at this point and I don't know when the new low sulphur in diesel was mandated. Of course the newer low sulphur was probably set in NA first because of emissions in California.

When in fact Jet A has much more sulphur than the newer low sulphur diesel available at the pumps. Diesel does have more lubricity than jet fuel or maybe kero due to additives for injector pumps in Diesel engines. Maybe this is why more smoking at shutdown
when using diesel in our turbines. Also just read that some aviation companies have pilots of Diamond aircraft ( running Diesel engines) must sign a waiver when refuelled with Jet A fuels...as they are too "dry" when it comes to injector pump lubrication.

Oh, one more thing Len because I noticed you have a Wren 44 turbo prop. One of my flying buddies tried to run diesel in his Wren 44 (non-turboprop) and it would not run properly. So, it does not seem to work in "all" engines.

My Jet Central's, Behotec and Jetcats all run great on it.
