Can you mix E5 and E10 petrol?
This is a common question and the answer is straightforward.
E5 and E10 can be safely mixed in E10-compatible vehicles creating a blend with 5-10% ethanol content.
The mixture helps maintain fuel system compatibility and provides proportional environmental benefits.
No performance issues or damage will occur from this combination.
Mix E5 and E10 freely in compatible vehicles based on availability and pricing.
The resulting blend is safe and effective.
Never mix these fuels in E10-incompatible vehicles as any ethanol content above 5% risks damage.
