Comments On Dec 27, 2009:Switched from GN4 to HP4S about a year ago and ever since then I will not run anything else in my 400EX. The 400ex wet clutch design runs from the same oil sump as the entire engine basically and i noticed better Clutch operation running this synthetic oil. Less drag and felt like stronger shifts. Highly Recommended

Comments On May 27, 2009:there's a reason why amsoil use only the GN4 in their comparison instead of the HP4S - because it's actually better than amsoil.
