Is B50 Safe for Diesel Engines? Here’s What USU’s Mechanical Engineering Expert Says

B50 — a blend of 50% palm-based biodiesel (FAME) and 50% fossil diesel that becomes mandatory starting July 1, 2026 — has proven safe across roughly 80–90% of technical test parameters, though that's no absolute guarantee for every engine; the trade-off is a slight rise in fuel consumption, around 1–3% compared to B40. The biggest risk isn't B50 itself, but rather dirty tanks, aging filters, and poor maintenance, so the key remains the same: use fuel from official channels, and keep tanks, filters, and hoses clean through regular checks
