Why not to give vegetable oils a chance?
Cheaper to produce and requiring fewer industrial processing than biodiesel, vegetable oils are a great option to enhance the living standards in rural communities and to provide a cleaner fuel for urban transportation. Instead of relying on the economic, political and social pressure of the OPEC mafia, why not to develop an indigenous source of fuels suitable to the most distinct regional realities? And vegetable oils also perform well on older engines, actually better than regular diesel oil.

I once saw a Fiat Punto fueled by olive oil. That was insane to say the least.
With olive oil being a highly-valuable commodity, it does not make sense at all to use it as a car fuel. Unless the oil was produced at the same location the car was driven.
Hi! I have a 96 Tamaraw FX with 2C engine. Can I run filtered waste vegetable oil in it without modifications? Will I have less emissions also? Thanks!
As long as the glowplugs are working nicely, you can use veggie oil without any harm. Just check the seals and gaskets of the injection pump and, if in doubt, get them replaced with some made out of synthetic materials. The hoses require some attention too, as they might eventually not just be prone to degrading when in contact with vegetable oils but also clog as old sediments accumulated in the fuel tank and fuel lines are carried by the oil. The fuel filter may need to be checked for the very same reason. Anyway in a 20-year old car it's expected to undergo some maintenance before you do any move that radical. In regard to emissions, black smoke is likely to become less visible, while nitrogen oxides may increase a little (though it's not a problem at all as it's fully reabsorbed during the feedstocks' growing cycle). As the 2C engine features indirect injection, it actually benefits from vegetable oil as a fuel and increases the fuel-efficiency because its combustion is a little slower compared to regular Diesel fuel, thus being more suitable to the pre-combustion started at the prechambers.
Wow! Is Manila temperature suitable for using 100% WVO? Or is it better to mix WVO with commercial diesel for the 2C engine?
So much more efficient than brewing biodiesel, which is only reasonable when animal fats are used.
Temperature is not an issue in Manila. Even in the Scandinavian countries there are WVO users/endorsers and they often have to deal with near-zero and even sub-zero temperatures.
Beef tallow and pork lard are useful as a fuel too, but they're better off be heated previously and preferable to blend with veg oils or to use as a biodiesel feedstock.
