Carbon Buildup and Fuel Economy
A 5 Series with significant intake valve carbon buildup can consume 15–20% more fuel than a clean engine. At 12 L/100km on a dirty engine vs 10 L/100km on a clean engine, over 10,000 km that difference is 200 litres of petrol — approximately RM 450 at current Malaysia fuel prices. The walnut blast service pays for itself in fuel savings within 50,000 km.
