What is Biodiesel (FAME)?

Standard diesel in Europe contains up to 7 percent (B7). Higher blends need approval. HVO is a different renewable diesel. Biodiesel absorbs more water than fossil diesel and can encourage microbial growth in tanks that stand for a long time. Its cold-weather properties can be worse, which is why winter diesel blends are adjusted. HVO, made by hydrotreating oils and fats, has properties closer to fossil diesel and is approved for many engines.

How it works

The fuel burns like diesel in the engine.

Why it matters for your car

Higher blends can affect seals and filters. Check the manufacturer's approvals.
