One financier's testimony about his own experience with coco-biodiesel (at a mere 1.7 % blend) has been posted at the Finance Manila blog. Excerpt:

The experiment was confined within the following parameters: One 2.2 Crdi Hyundai Santa Fe with approximately 70 liters fuel tank capacity, one canister of Bioactiv measuring 500ml, and one full tank's worth of diesel from Shell, allegedly complying with the 1% Biodiesel requirement.
Checking the manual pamphlet, it was stated that the vehicle could accomodate even up to a 5% biodiesel blend without damaging the engine, so placing 500ml on a full tank with Shell's already included b1 blend would be far off from the 5% limit.
To cut the report short, regular daily traffic in city driving previously gave a mileage of around 7.5 kilometers to the liter, but with the addition of Bioactiv, it increased my mileage to 8.3 km/l under the same driving conditions!

The rest of the article cites material from the studies of Rafael S. Diaz, Managing Director of the Asian Institute of Petroleum Studies. His work on behalf of coco-biodiesel will be a topic for future posts. Abangan!
