In prep to replace the secondary guides I have been researching the material type. I believe the new guides to be PA 46 Nylon. its a pretty common material for all car manufacturers. Does anyone know if the original was a PA 66?.

it brings up the topic of oil viscosity but not in detail. Is a 30 w too light for this chain design ? I don't know if we get a glass reinforced version of a PA 46 but the standard version is a Hardness Rockwell M of 92. Very thin contact surface Nissan could have put a little meat on the bone there.
