Oil Change:
Typically every 5,000 - 7,500 miles or 6-12 months, check manual for specific recommendations.
Tune Up:
Spark plugs, ignition points (if applicable), fuel filter, air filter usually recommended every 15,000 - 30,000 miles.
Timing Belt Chain:
M10 engines utilize a timing chain, which is generally maintenance-free for the life of the engine but requires inspection for wear.
Engine Oil:
Refer to manual for specific API service classification and viscosity (e.g., SAE 20W-50, 15W-40 typical for the era).
Coolant:
BMW approved coolant (typically ethylene glycol based) mixed with distilled water (50/50 ratio).
Transmission Fluid Manual:
GL-4 gear oil (e.g., SAE 75W-90 or 80W-90)
Transmission Fluid Automatic:
Dexron II or equivalent ATF (Automatic Transmission Fluid).
Brake Fluid:

Power Steering Fluid:
ATF (Automatic Transmission Fluid) or specific power steering fluid.
Rust:
Common rust points include wheel arches, rocker panels, strut towers, and the spare tire well.
Fuel Injection:
Aging fuel injectors, fuel pressure regulators, and electrical connections can lead to performance issues.
Electrical Gremlins:
As with many cars of this era, aging wiring harnesses, grounds, and switches can cause intermittent electrical problems.
Suspension Wear:
Bushings, ball joints, and tie rod ends are common wear items, impacting handling and alignment.
