In winter, we know that we have lower outside temperatures, which means lower intake and oil temperatures. Is it therefore practicable to refuel in a vehicle that is designed for Super Plus under these circumstances (under 5 – 10°C outside temperature) without hesitation and without any restrictions? Or are the lower operating temperatures correct, but due to the slightly higher oxygen content, the tilt within the combustion chamber increases again? Or do I generally have to use the Bren num (its design and spark plug arrangement) and can ignore the parameters operating temperatures?
