Carlube fully synthetic 10W40 engine oil is designed for use in 4-stroke motorcycle engines. Suitable for use in both European and Japanese air- and water-cooled engines. Carlube motorcycle oil ensures good lubrication of new multi-valve engines under high loads, for example in racing conditions. Maintains good lubricating properties better than mineral oil, protecting the engine during long-term road driving up to short stop-start cold start conditions. Also suitable for use in older engines that use API SF and SE engine oils.
