Compare detour cost with the saving. A lower litre price only helps when the extra drive is small.
Set a target-price alert for stations on your normal route instead of watching prices manually.
Compare E10 and E5 only when your vehicle is approved for E10 and the real price gap outweighs any consumption difference.
Compare fuel prices before filling up using Tank Alert or the ADAC petrol price app to always find the cheapest station near you.
