Oil Change: When, How Often, and What Does It Cost?

Engine oil serves several vital functions: • **Lubrication**: Reduces friction between moving engine parts and prevents wear. • **Cooling**: Transports heat away from heavily stressed areas. • **Cleaning**: Absorbs combustion residues and metal particles. • **Corrosion protection**: Protects metal surfaces from oxidation. Over time, oil loses its lubricating ability. Additives break down and contaminants accumulate. If not changed in time, engine wear increases dramatically – in the worst case, engine failure can result.

Intervals vary by vehicle and usage: • **General rule of thumb**: Every 15,000–30,000 km or once a year – whichever comes first. • **Short-distance drivers**: Should change every 10,000–15,000 km, as frequent cold starts stress the oil faster. • **Long-distance drivers**: Can often use the full manufacturer interval. • **Long-life oil**: Some manufacturers (e.g., VW, BMW) allow intervals up to 30,000 km with special long-life oil. Whether this is advisable depends on driving habits. **Important**: Follow the manufacturer specifications in your service booklet. If unsure, we're happy to advise.

Costs depend on oil quantity (4–8 liters depending on engine) and oil specification. Various service packages are available: • Oil change (without filter) • Oil change with filter • Premium oil change (long-life oil + filter) • Additional air filter High-performance or turbocharged engines often require more expensive specialty oil.

• **Viscosity**: The correct viscosity (e.g., 5W-30, 0W-20) is listed in the owner's manual. It determines flow properties at different temperatures. • **Manufacturer approval**: Only use oils with your vehicle manufacturer's approval (e.g., VW 504.00/507.00, BMW Longlife-04, MB 229.52). • **Synthetic vs. mineral**: Synthetic oils offer better protection, longer service life, and better cold-start properties. They are mandatory for modern engines.
