High-sulphur fuel ruining injectors monthly: what to do?

Local diesel measures high in sulphur; six injectors were replaced in three months.
We added a coarse filter and water separator with limited effect.
Change fuel source or change the set's configuration? How to weigh cost?

Test the fuel for sulphur and water first; high sulphur corrodes injectors and filtration cannot fix it.

Fine filters and regular changes cut particles, but sulphur only goes away with a different fuel.

Compare annual injector cost with the fuel premium; a stable source usually wins.
