Oil Change:
Recommended every 5,000 - 7,500 miles (8,000 - 12,000 km) or annually, whichever comes first. Refer to manual for precise interval based on driving conditions.
Air Filter:
Replace every 15,000 - 20,000 miles (24,000 - 32,000 km) or as needed based on dusty conditions.
Spark Plugs:
Replace every 20,000 - 30,000 miles (32,000 - 48,000 km). Use specified plug type (e.g., Bosch W7DC or equivalent).
Timing Belt:
M10 engine typically uses a timing chain, not a belt. Check for chain tensioner wear.
Engine Oil:
API SF or SG quality, SAE 20W-50 or 15W-40 recommended for general use. Refer to manual for viscosity based on temperature. Capacity approx. 4.5 liters (4.8 US quarts) with filter change.
Coolant:

Rust:
Prone to rust in common E30 areas: wheel arches, rocker panels, jacking points, battery tray.
Cooling System:
Plastic coolant expansion tanks can become brittle and crack; water pumps and thermostats are common replacement items.
Bushings:
Wear in control arm bushings, trailing arm bushings, and sway bar bushings can lead to imprecise handling and noise.
Fuel System:
Older fuel pumps and injectors can fail; fuel lines may degrade. Check fuel pressure and injector spray patterns.
Electrical:
Wiring harness issues, corroded grounds, and failing relays are not uncommon in older vehicles.
Bmw Legacy:
BMW has a long-standing reputation for engineering, performance, and driver-focused vehicles, a heritage the 3 Series embodies.
E30 Introduction:
The E30 generation of the 3 Series was introduced in 1982, replacing the E21. It was a significant evolution, offering improved dynamics, space, and modern features.
E30 Variants:
The E30 platform was produced in various body styles including 2-door sedan, 4-door sedan, convertible, and the iconic M3.
Production Years:
E30 series production ran from 1982 to 1991.
Manufacturing Locations:
Primarily Germany (Munich, Dingolfing).
