Keep it consistent. Synthetic oil for motorcycle engines is carefully designed by chemists to make sure all of the oils and additives interact to the benefit of your vehicle. Although most oils are similar, using the same product consistently will prevent negative interactions between different brands. Discover the joy of a cleaner ride. Synthetic motor oil is distilled and purified, so it has a lower viscosity, fewer contaminants, and burns cleaner, keeping your motorcycle happily humming along.

No matter hard you ride, synthetic motor oil will keep your motorcycle moving along. At high temperatures, synthetic oil doesn't break down like conventional oil – so at high RPMs or over rough terrain, synthetic oil will keep you riding even when conventional oils won't.
