Motul 5100 4T 15W50 Ester Semi Synthetic - 4 Litre Motorbike Engine Lubricant

Looking for a dependable 15W50 bike oil that keeps your four stroke engine protected and your shifts silky smooth mile after mile? Motul 5100 4T delivers a proven ester blend semi synthetic formula that riders trust for daily commuting, weekend blasts and mixed surface riding. It offers robust film strength at high temperature, excellent wear control and a confident clutch feel, all in a convenient 4 litre pack.

We use this oil in our own machines and in customer services at MJ Modifications, and the feedback is consistently positive for clean running, crisp gear engagement and reduced consumption compared to basic mineral options. If you want a no fuss service fill that just works in real world conditions, this is a standout choice.

Why riders choose it

• Ester enhanced semi synthetic base for strong protection under heat and load
• Helps guard the gearbox and promotes slick, precise shifting
• Stable 15W50 grade supports hot running, fuel dilution resistance and lower top up needs
• Wet clutch friendly for consistent engagement and slip free performance
• Mixable with mineral or fully synthetic lubricants if needed

Where it works

• Four stroke engines with combined or separate gearboxes
• On road riding as well as trail, dirt, Enduro and trial use
• Bikes with modern emissions kit including catalytic converters and exhaust air injection
• Models that specify a 15W50 grade, including popular BMW and Ducati applications
• Also suitable for many ATV and UTV four stroke engines requiring this viscosity

Choosing the right grade

Always refer to your owner manual to confirm the required viscosity and specification for your engine and climate. If you are unsure, we are happy to help you match the correct lubricant to your bike.
