Depends on how long you want to keep it..... IMO, pretty cheap maintenance..... I change mine every 120 days, since i dont put a lot of the miles on the car, which so happens to be about 3k miles..... Forget using that oil life monitor, I dont believe those things... It may be all fine and dandy, but I wont go more than 4k without a change, and sometimes we do it at almost 2500......
I have heard you can do a complete cooling system flush, and in my Q45 service manual it describes a really good way to do it.... A synopsus as follows-- Drain the radiator, and drain the block drains. Fill the radiator with distilled water, and run the engine for a little. Drain/refill until you get clear water draining, then refill with antifreeze the proper amount....
