Certainly a standard preventive maintanance article/filter.
Gets overlooked by many DIYers ...
The three main ones I see neglected or unknown are:
The oil wick under the distributor rotor.
The P/S filter
The oil reservoir dip-stick on the early Bosch Mechanical FI [ this one always amazed me with 113 owners that never knew it was even there after having owned the car for years...]
Costly consequences on all that can be averted for short $$$ and a quick check.
