I would hang tight and keep up a regular quality oil change schedule.
I have the same year & motor as you and about the same mileage. Very robust and reliable vehicle - daily driver (rural not 'burbs).
I change at least quarterly (do quite a lot of towing). Been using Castrol Magnatec 10w-40 for several years. Our air temp range is about -2C to 45C.
A lot of USA folks use the 5w-30 spec - I guess it would depend on locale.
Never had the tick.
