diesel and gasoline engine oil

[beetle]

im doing a feasibility study/business plan on ink. i found out a week ago that a group of students already used engine oil as their pigment in ink production (ang masama pa, pumasok sa top ng competition 2 years ago). they used used-DIESEL engine oil.

ang gusto sana ng group namin ma-utilize din yung gasoline engine oil. (tama ba?) or better yet combine yung diesel and gasoline engine oil for ink production.

here are my questions:

1. whats the difference between a diesel and gasoline engine?

2. whats the difference between a diesel and gasoline engine oil BEFORE and AFTER use?

3. what are the contents of a diesel oil? engine oil?

thanks po! hoping for a very fast reply!

Try visiting the sites of oil manufacturers like Mobil1, Castrol, Pennzoil, etc. They should have the explanations you need.
