Here's my stupid question of the day...At $25.00, why not just change the oil according to the Owner's manual?
Ok...So you want to stretch your OCI....I hear you, but you are locked into periodic OCI's for the life of your car. Im sure the oils degrades differently as the car ages... So while an extended oci sounds great, if you don't keep shelling out for the UOA's you could be doing more damage over the long run.
For the 25 bucks per, just use that money to change your oil more frequently.
Many Synthetic oils are 25 dollars or less for a 5 qt jug.
Just my opinion.
