I do lots of short trips, but also some highway runs. Can the FL820S safely go longer than 6-8 months if the mileage is in the 3,000-4,000 mile range. 2001 lincoln Towncar 4.6 V8. What do you guys think the longest safe interval is for this type of driving.
 
I'd say whatever you're comfortable with for your oil oci, the FL820S will handle.

Your driving profile, with owners manual as a guide should determine oil oci, filter change would correspond.
 
The manual written in 2000 or 2001 says 3 months or 3,000 miles for severe service, but I think the oil specs have improved some and just wanted to be sure the filter could take a longer interval.
 
Yeah, 5k/6 months would be an average minimum. If you're comfortable going further on the oil, the 820S should have no issues. IMO, up to 1 year max, good to go.

But again, the oil oci would lead, the filter would follow.
 
I do 10K OCIs with smaller MC filters in my Duratechs over 8-9 months. No problems.
