Thanks guys, this is all helpful information.
The basics, as I am seeing them, would be:
no moisture
pH neutral
filtered to <10 u
reduce the viscosity, with heat or additives, to ensure atomization and to bring the fuel closer to its flashpoint.
How these are achieved is another whole can of worms (hey, do you think worms are a good fuel additive?)
I realize that some find no need to preheat or thin WVO or perhaps even to filter to less than 10 u but I suspect no one is opposed to the notions on principle.
It occurs to me that attaching a filter from the diesel truck engine of my choice beats chasing my tail looking for a specification that may not exist. If the filter plugs (too soon) then I need to improve my process and if it never plugs it is cheap insurance.
Just tonight I got my nose into a copy of the Diesel Engineering Handbook (1969) and as I understand the recommendations for fuel are that steady, high loads and low engine speeds are important as fuel viscosity increases. Sounds like a Listeroid. The author describes the same results you mentioned for failing to heed sound advice.
As far as the side points on various additives go I find those valuable because I never know what will be available to thin the WVO. At the moment it has been my good fortune to be given 100-120 gallons of heating oil. So is it a case of thinning the WVO with HHO or adding lubricity to the HHO with WVO? I guess it depends on which is going to be in best supply.
If anyone would like to mention any important basics I have missed I would welcome it.
