According to one manufacturer it is every 3000 mi.:
After you install your Frantz Oil Filter, the first element change
should be at 500 miles. Thereafter, these standard guidelines should
be followed.
Gasoline engines: Change your TP Element every 2000-3000 miles.
Diesel Engines: Change your TP Element every 1500-2500 miles.
Change more often for dusty driving conditions.
