Rudolf diesel did not design our engine, he designed his....the engines in our cars came many years later, and were designed to run petrol diesel fuel.
As for using a lot of diesel, I can't really afford it, but I have no choice, as there's no WVO around here and for my purposes I'd need the full heated tank system anyways, which would cost $$$$ that I don't have. Too many obstacles to use it. As for biodiesel, I did run it, but it is only 3-5 cents less a gallon around here for B20 (the highest blend available at a pump) B100 is only available by delivery in orders of 180 gallons or more, price? $3.50 a gallon
The one station that has the B20 (and delivers B100) is 12 miles from my house, utterly not worth it, it'd cost $3 just to go fill it up.
If diesel goes above about $3.30ish a gallon I'll switch to Sams Soy oil blend again. I have a rewards card for my gas station that takes about 12 cents a gallon off, so right now the 2.99 only costs me about 2.87 or so.....
I support the wvo idea, I just can't really take part in it.
