Oh well, there goes my vacation in the Bahamas. Thanx to RT for not sending me money.
IF, (I haven't heard from you reporting your success yet and so it is an IF) you can make it as simplified as you said it might not be too bad. Assuming the WVO consumption is the same as diesel and doesn't need more to go the same distance, and counting the costs of the degeling agents for winter use, it might pay for itself.
However, I still disagree with your statement that buying fuel from the pump is being lazy. If my neighbours see a 55 gal drum on stilts in my yard, they might have a problem and start point out sections in the covenant and have me remove it and my shed that I have in the yard that is not supposed to be there. My garage will not accomodate much more than my workbench and grinders, etc, etc, so having it in there is not an option either. Sometimes, it is just not possible,
