Downunder, How does turbine oil perform? Have you heard concerns of it being carcinogenic?

Shell A has 3% acetone already added to it...BP Racing fuel doesn't. For that reason I prefer the Shell A except I can't buy it other than in their drums. BP methanol (which I get from a local Ampol distributor, just to confuse things) has it in bulk so I can refill my drum.

As for the turbine oils, yes, I've heard about it being carcinogenic but so are tomatoes! As an aircraft engine fitter I was immersed in the stuff for many years, breathed the fumes from jet engines using total loss oil systems and nun off us was effer effectid buy it

Seriously though I think this is only a recent development because none of the cans of oil were labelled as being carcinogenic as it seems they are now (avoiding possible litigation?). As to how it performs, I found that my engine was running about 10C hotter than with all castor. For this reason I'd never use any of the inferior synthetics.

Yep, find us everywhere!

Currently living O/S and will be back on shore in about three months, will need to get batch of fuel going then.

Thinking about 80 Shell A, 10 Castrol M and 10 Mobil Turbine or maybe drop the oil to 18% total for certain usages.

The thing I like about Shell A is the included Acetone. Seems to keep the flame lit on cold rich runs and help transition a bit.

Status: offline 		DerFly...can't see any problem at all going 50/50 with castor and Jet Oil 2. Of all the synthetics Jet Oil was the only one that George Aldrich had any time for, in fact he said he was quite impressed with it. We've got him on video in our club's library when he did a lecture here in Adelaide some years ago where he talked at some length on Jet Oil.

The reason I mentioned tomatoes as being carcinogenic was because I read a report once (in New Scientist magazine from memory) where rats had been force fed tomatoes and they developed cancer so therefore tomatoes were carcinogenic. But when applied to humans you'd have to eat something like 10 kgs a day for years on end before you'd be at risk. Maybe turbine oil is similar? Who knows....

As for acetone, Clarence Lee is finally coming around to saying that there are advantages to using it but in support of it he's used the data (and some quotes) directly from the club web page on fuels that I've had there for years!

Downunder, any chance you could post the URL for your web page on fuels?

Status: offline 		majortom...here's the link to that web page. I held off for a couple of days because the server seemed to have been down.
http://www.holdfastmac.com.au/techfuels.html

Also click on the link to Tables for more info on things like heat energy, air/fuel ratios etc for other types of fuels.

Status: offline 		Downunder, got your website, thanks much; had a good time browsing around. Found your comment about 5% acetone in four-stroke fuel mix. What is your theory behind more acetone for four-stroke use?

Status: offline 		Where do you get things like:
80 Shell A
BP Racing fuel
10 Castrol M oil
10 Mobil Turbine oil
Mobil Jet Oil

How much are these products?

I'm planning on mixing my own fuel as well. I wanted ~2% nitro though. The best price on: nitro is $35 a gal, Castor is $23 a gal, Meth is $3 a gal, Klotz is over $8 a qt.

Status: offline 		majortom...the mention about 5% acetone in 4 strokes was from personal experience by John Modistach (who wrote the first part). He's been making fuel for our largest hobby shop for many years now (and also runs the server that hosts the web site).

rsieminski...these are just brand names for methanol and oil available in Australia. The main point was that Shell methanol already has acetone added but BP is 100% methanol. Castrol M is our equivalent (as far as I can make out) to your Bakers AA (and maybe one of the Klotz varieties). Mobil Jet Oil 2 is what is used in virtually every full size gas turbine in Australia (both civil and military). The brand may be different in America but it will still meet the same Mil Spec so should work exactly the same.

How does the Mobil turbine oil compare cost wise to Klotz or CoolPower oils sold through hobby shops?

Can you order it from your local Mobil distributor?

I'd like an alternative to the synthetic oil I use at the moment.
