Is it true that there is no longer any requirement to label

Worse.
I read that, starting in 2007, in some places, California and some
Canadian Provinces included, it is regulated that all gasoline sold
must
contain at least 5% alcohol/ethanol.

Here in Ontario I was told not all gasoline must have 5% alky, but

5%

of all fuel sold must be alky - so 50% of all fuel sold being E10
satisfies the requirement. In practice, virtually all 87 octane
will
be e10. Premium 91 will (from some companies, at least) be E0,

making

the blended 89 E5. Since significantly over half the gasoline sold

in

Ontario is 87 octane, this would excede the requirements. - Just

from

what I've been told, but you can never trust the elected idiots, or
worse yet the beurocrats


IF I ever get a plane, all these silly fuel issues would be a real
irritant. I haven't been paying much attention to the new diesel
aircraft engines becoming available. Since I should be making my
own
biodiesel by the end of this Summer (for something less than 45
cents

a

gallon), are any of the new diesels in the O-200/Rotax 912 class?




What do you grow to make biodiesel?


Relatives that own restuarants and have to pay to dispose of waste

fryer

oil!




You grow relatives?


Well, somebody planted the seed and they tend to grow on their own. I

just

fertilize them now and then!




What do you actually do to the waste fryer oil to make it useful as
biodiesel?



A common misconception is that biodiesel is just filtered vegetable oil;
this is not the case. Straight Vegetable Oil (SVO) (and Waste Vegetable Oil
(WVO), for that matter) don't have the proper viscosity to run in a diesel
engine unless they are heated to the 140 F to 170 F range. More
importantly, they solidify at too high a temperature and will clog the
injector pump and injectors. Biodiesel is vegetable oil that has gone
through the transesterification process. Simplified, you mix many parts
vegetable oil with one part methanol and a little bit of lye, then heat and
stir the mixture. After a while, you have a tank of cloudy oil with
glycerine on the bottom. You then bubble air through the oil until it is
no longer cloudy, and the clear oil is biodiesel.
