Reg,

With the need for only 20% content, and with the hassles of getting/ordering/buying good castor, making your own lube oil looks better and better all the time. A guy could just take a weekend off to make up a gallon and be set for some five gallons worth of diesel fun. Just make it another part of this fascinating hobby. With the way the hobby is going these days, buy and fly, we have the distinction of making our own d*mn fuel, if you please.

So, we seem to be edging toward something TRULY radical. Biofuel lubricated with Bioil and supplemented with a Biocetanebooster. Geez, I feel like hugging a tree.

About viscosity. I'm not great on the molecular level so this may be a little bit off the mark but the reason I've got a thing for a no lube fuel is this. Kerosene has a low viscosity but some lube qualities. Ether has a VERY low viscosity and NO lube qualities, (I'm assuming). Put the two together at say, equal parts and what do you get? A very low viscosity solution with very low lubricating qualities. So to make up for that, you have to add a lube with substantial viscosity. So,, what if you have a good, clean, biodiesel fuel that is an oil, after all, to start with. It'll have considerable lubricating qualities I would think, despite the process to make it a fuel. After all, kerosene is also considered an oil as in fuel oil etc. So we have a viscosity problem with biodiesel. Would that be the ONLY issue? What if we found an additive that contributed to lowering the viscosity to that of a "normal" fuel? Yes, we've covered that ground but I'm just explaining my reasoning. This thread is very long and that answer might be somewhere but in a scattered form. Can anyone summarize?

The recent run of a no lube fuel with my own biodiesel and kerosene was an improvement over the ether/bio mix. A leaner setting, more power and less oil out of the exhaust. I won't try measuring the exhaust oil yet, not till I can see a dramatic improvement. Recent research has revealed that if you need to "wash" your biodiesel fuel, then your process is not the best. Even there, a wash can be OK but it should only be needed to be done at the most twice. I had to do it five times and I still had some cloudiness in the mix that never completely settled out. And a test of the Biodiesel I was given, (the ether mix) showed that it wasn't fully processed to the max as well. I'm going to try again to make up a more refined mix. Lots of time now, now that the weather has closed in. No heavy snow yet but bloody awful cold.
