I?have been following this conversation with interest. I am not an expert on 
biofuels, but the missing question with all of this, is what quantity of 
biofuels and biolubricants can be sustainably harvested without damaging 
ecosystems, and impacting the production of food for the world's population. 
I suspect not enough to permit the burning of biofuels at the rate we 
currently burn fossil fuels. That implies that we are going to have a lot 
less energy to run vehicles, and a lot less vehicles.? So that also suggests 
that we should be putting a lot of thinking into alternative ways of doing 
things that don't involve the mass use of vehicles for transportation and as 
labor saving devices. It will be the hugest reallocation of resources since 
the industrial revolution. It will be in fact the reversal of how the 
industrial revolution has allocated resources.

    There are a lot of synthetic oils on the market today, and, in fact,
if you love your engine, you should be using them rather than petro oils
as they are much superior, reducing friction and heat. That's not to say
they are made from all renewable sources, but it's a start.
    Also, biodiesel works great for two-stroke lubrication -- the gas
mix in chainsaws, etc. Canola oil works great for the bar/chain lube in
chainsaws, except when it gets too cold.
