We get a lot of queries from car owners about fuel quality. But the one that keeps on coming back is whether cheap supermarket fuel is as good as big-brand petrol and diesel. It’s an important question because there can be a significant difference in what it costs to fill up at a supermarket compared with at a fuel brand’s station.
We all want to save money where we can. Whether that’s with petrol or diesel that costs less, or apparently more expensive fuel that’s cheaper because it improves economy. But most importantly, we don’t want to do our cars any damage, so how good is supermarket fuel?
