Not all miles are created equal. The way you ride has a direct impact on how quickly your oil degrades.
City Riding (Stop-and-Go)
Frequent stops mean your engine doesn't get to fully warm up, leading to condensation buildup (moisture) in the oil. This can create sludge. Short trips are the hardest on oil.
Highway Cruising
Steady speeds and consistent temperatures are ideal for oil life. However, sustained high speeds can cause oil to thin out more than usual.
Spirited/Weekend Rides
High RPMs and aggressive acceleration create more heat and shear stress on the oil molecules. If you ride hard, you may need to change your oil more frequently.
