It depends on how much you save per liter and how far you have to drive. In many cases, the extra trip can erase most of the savings.
To know whether driving to a cheaper gas station makes sense, you need to consider four things:
The most common mistake is looking only at the fuel price without considering the cost of the extra driving.
If you save €0.06 per liter and buy 40 liters, the gross saving is €2.40.
But if you need to drive several extra kilometers, the fuel cost of the detour — and possibly other car costs — can reduce or even eliminate that saving.
In many situations, you may end up saving less than €1 or even losing money.
Every kilometer is not just fuel. There is also wear, maintenance, insurance and depreciation.

It depends on consumption, fuel amount and price difference. The calculator gives you the break-even point.
No. If the detour is too long, the extra driving cost can be higher than the saving.
In most countries, fuel must meet base quality standards regardless of the station. The main difference is usually the additive package.
Some brands add proprietary detergents or additives that may help keep injectors, valves or the fuel system cleaner over time. For most everyday drivers, the short-term difference is usually small.
Myth: cheaper fuel is bad and can damage the engine.
Reality: regular fuel sold legally must meet quality standards. Differences usually come from additive packages, service model and operating costs, not from the base fuel being unsafe.
The most important thing is not only the brand, but also avoiding habits that do hurt the car, such as constantly running the tank very low or neglecting maintenance.
