The RAC highlights how there is a myth that supermarket fuel is somehow less efficient or bad for engines. All supermarkets conform to the same British Standards as branded fuels supplied by major oil companies – EN228 for unleaded and EN590 for diesel.
Every engine is designed to work with supermarket fuel and for several decades engines have been fitted with systems that automatically prevent issues like “knocking”.
Using a higher grade fuel will provide a degree of fuel efficiency but may not be significant compared with other factors which affect fuel economy.
These are usually driver behaviour, vehicle load, tyre pressure, traffic and weather conditions.
The RAC also said: “Make sure you fill up at forecourts away from the motorway as well if you can manage it.

Following Rishi Sunak’s fuel duty cut in March, many major retailers were slow to apply the 5p drop, with some drivers not seeing any changes in price at all.
In more recent months, the cost of wholesale oil has dipped after global concerns earlier in the year, most notably the Russian invasion of Ukraine.
Despite the drop in price, petrol and diesel prices in the UK are still higher than many other nations in Europe.
The latest data suggests that petrol and diesel prices should continue to fall, with petrol down to 165.75p and diesel at 181.93p per litre.

Transparency is also key for savings, with Northern Ireland’s Consumer Council fuel price checker helping to lower prices across the nation.
It allows drivers to monitor the prices in their area, or show them cheaper alternatives around the country.
Currently, Coleraine has the cheapest average petrol price at just 159.3p per litre, compared to Bangor, where average prices are 168.4p.
Some lucky drivers in Belfast can find unleaded petrol for just 155.9p, with drivers in Bangor losing out again, having some of the most expensive petrol in the country.
Supermarkets only make up around 16 percent of all UK forecourts but are responsible for 44 percent of total fuel sales.
As a result, drivers are more likely to see price drops being passed on at the pumps, allowing drivers to cut their own spending.
Supermarkets are also more likely to do special events, as seen in February when Morrisons offered customers the chance to see significant savings on their petrol and diesel.
If drivers spent £40 in store on groceries or other items, they would receive a fuel voucher for 7p off every litre of fuel.
This scheme was only in place for roughly two weeks and was at a time when fuel prices were below 150p per litre.
With the cost of living crisis continuing to rage on, supermarkets may introduce a winter savings scheme to help out.
