That's 18 years till I'll need to change mine again then!By the very nature of it being a filter will mean that it will do its job and stop impurities from getting to the pointy end of things. Like any filter, there will be a build-up of crud over time so will need changing and can only improve how the car runs no matter how minor. Well worth doing.
Edit: every 36,000 miles so if it's original, well overdue.
