Biodiesel testing is vital for ensuring fuel efficiency, compliance with regulatory standards, and safeguarding engine health. At ASAP Labs, we understand that biodiesel can be challenging. With the hydroscopic (i.e., attracting water) nature of biofuels combined with their vulnerability to cold temperatures, there are many opportunities for failure. In addition, questions often arise about the viability of fueling vehicles with straight vegetable oil (SVO) or waste oils from cooking and other processes. Using these “fuels” without intermediate processing/testing can cause engine failure and other issues. SVOs and other waste oils differ from biofuels and conventional diesel in important ways. SVOs are generally not considered acceptable vehicle fuels for large-scale or long-term use and should be tested on a regular basis.
