When changing the oil in your motorcycle or scooter, it is good to have an idea of how far your vehicle can travel before needing more, and what kinds of oil are best to use. Yamaha “Yamalube” oil tends to be the brand of choice for most motorcycles and scooters. For maximum performance and efficiency, use a Yamalube 2S oil. Most motorcyclists and scooter owners will estimate travel between 400-600 miles from one quart of oil.
However it is good to continue to check your oil level regularly before the light flips on your vehicle.
