Can soybean biodiesel be used directly in diesel engines without modifications?

Yes, soybean biodiesel (especially blends like B20 or even B100) can be used in most modern diesel engines without any modifications. It provides good combustion, reduces emissions, and enhances lubricity. Some cold-start issues may arise with higher blends in colder climates, but these are manageable. The GlobeCore USB plant ensures fuel consistency and purity, which is critical for engine compatibility and long-term reliability. Biodiesel produced this way meets ASTM and EN standards for use in standard diesel engines.
