1994-1998 Porsche 911 (993) Maintenance & Service Schedule
The Porsche 911 (993), produced from 1994 to 1998, was the last air-cooled 911, making it a highly desirable and collectible model. While Porsche originally outlined a factory maintenance schedule with service intervals designed for a newer car, these cars are now over 25 years old, requiring a more proactive approach to maintenance.
In this comprehensive guide, we provide both the original factory maintenance schedule and a modernized service plan tailored to the aging components and known wear points of the 993. Key areas covered include oil changes (more frequently than originally suggested), valve adjustments, brake system maintenance, suspension wear, and gearbox servicing. Additionally, we highlight common aging concerns, such as leaking camshaft seals, worn suspension bushings, and distributor belt failures in VarioRam-equipped models.
