A header is at the top of the page and a footer is at the bottom. They are both set up to stay constant throughout the document no matter the page. You can also add page numbers and different thing that will vary uniformly throughout your document.
In older trucks and cars, the answer is yes, the palm oil or bio diesel may destroy rubber gaskets over time. In cars produced after 1998 or 2000 I think it does not matter as the seals and gaskets are made of different materials, designed to tolerate bio diesel. The palm oil will not effect the engine otherwise than it will be a little less powerful on pure palm oil. Don't try to run it on palm oil unless you live in a hot country, or have a heater element placed in the fuel tank in a colder climate.
