FAQ

Frequently asked questions

Is XTL compatible with my diesel engine?

Yes. XTL is a drop-in fuel — it works in most existing diesel engines and tanks with no modification.

XTL vs B100: what’s the difference?

XTL is a synthetic renewable diesel (up to ~90% less CO₂), usable without modification; B100 (FAME) is cheaper and unlocks Crit’Air 1 but needs compatible engines.
