Using the right motorcycle oil and changing the oil regularly is important to get the most out of your Royal Enfield. Oil reduces friction and lubricates engine parts. Because engine lubrication reduces friction, components last longer.
It’s also worth noting that friction uses up a lot of internal combustion energy, converting it into heat instead of power. Oil protects metal parts from oxygen, preventing oxidation and further wear. To keep your Royal Enfield running smoothly, choose the right engine oil. This guide helps you choose the right engine oil for the Royal Enfield Thunderbird 350.
