Good day all,

Good to see your comments from your tests Andy. Most of conclusions seem to be falling in line with yours.

I do think that some synthetic oil in the fuel would be beneficial as Kelly and others have also mentioned. It should help keep the engines cleaner (less carbon). I have started to try an Amsoil 2 cycle oil as it is available at Canadian Tire so is easily obtained. I don't know about CT in Timmins but if the local stores here have it then it should be in the store there as well.

I found an interesting article in the Australian Control Line News issue 73 on F2C fuels (FAI team race). Again with reference to Tetra Ethyl Lead and Ferrocene. Not something we should be playing around with but an interesting read non the less.

There must be hundreds of articles/reports on F2C fuels etc that would be interesting it is just a matter of finding them; most undoubtedly buried in old issues of model magazines and organizational newsletters.

Interesting note about the F2C fuels is that they still use high ether content - 30% or so as they don't (can't) use a starter and require fast single flip restarts on hot motors (and they won't mess around with compression or needle setting while do so). So, their needs are different from our own but still makes for interesting reading.

In light of your comments on mixing naptha with the diesel fuel, I think I will pass on Kelly's suggestion to try that for the time being. You didn't specify percentages so it is hard to second guess whether you used a lot or a little.

I did find a local source for vehicle BioDiesel. B20 is what they sell - 20% BioDiesel and 80% petroleum diesel. I am going to give some of that a try. I am hoping I can pick some up before the weekend.

I am glad I picked up a graduated cylinder. it makes it dead easy to mix fuels with good accuracy and repeatability; sure beats my old recycled roughly marked Sig Dope bottle.
