The recommendation to clean the Amsoil EA Filter is 25,000 miles or 1 year, and replace after 100,000 miles or 4 years. Does the time frame actually matter? I can see how oil filter and oil would have a time frame due to acids and combustion by-products that can damage the filter media and such.
Or was the recommendation really just made to coincide with Amsoil's oil drain intervals? I ask because I probably won't get 12,000 miles in one year, and I don't see why it'd be necessary to clean the filter if it's not dirty.
