Stuck oil filter that won't unscrew: 5 emergency methods

5 methods (least to most invasive)

1. Strap wrench (10-20€) — universal, easy
2. Chain wrench — huge torque, deforms housing OK
3. Long screwdriver through housing — last resort
4. Gentle heat (hairdryer) for thermal locks
5. Remove fragment with pliers if filter destroys

Prevention

Hand-tighten + 3/4 turn max. Oil pressure self-tightens.
