When people say a chain lasted 5 years that says nothing as a bike that does not go anywhere is not going to wear out... I was riding 10,000 miles a year in every kind of weather and swapping chains every 3000 - 4000 miles and typically refresh my lube every 300-500 miles (depending on conditions) or when things get so grimy that the bike needs a good clean up.

The semi synthetic is nice in colder temps as it gets less gummy.
