You could have extended your oil change interval (OCI), You can usually double the miles or up to a one year interval. How much oil did you need to add betweem changes? This amount could have been reduced. What was the condition of the engine at 185K miles?

If you extend the OCI (to double the miles) it ends up costing the same as dino oil.
