20W50 4T Fully Synthetic Motorcycle Oil (ww16)
Optimized for Air-Cooled V-Twin Engines
This 20W50 4T Fully Synthetic Motorcycle Oil is a high-performance lubricant specifically developed to meet the extreme demands of air-cooled 4-stroke V-Twin engines. Unlike standard oils, this formula maintains superior oil pressure and film strength even under the intense heat generated by large-capacity motorcycles.

Questions & Answers
Is this oil suitable for Harley Davidson motorcycles?
Yes. This oil is specifically formulated for air-cooled V-Twin engines, including Harley Davidson models where a 20W50 viscosity is specified.
Can I use this in a motorcycle with a wet clutch?
Absolutely. It meets JASO MA2 standards, meaning it contains the necessary friction modifiers to ensure proper wet-clutch engagement without slippage.
What is the benefit of Fully Synthetic vs Mineral 20W50?
Fully synthetic oils offer much higher thermal stability and resistance to thinning at high temperatures, which is critical for air-cooled engines sitting in traffic or under heavy load.
Note: Always consult your owner's manual for the correct oil weight and service classification for your specific motorcycle model. Proudly distributed by 4boats.co.uk.
