Perushuolto

Perushuolto is a Finnish term meaning basic maintenance. It refers to routine service tasks performed to maintain a vehicle, machine, or equipment in good working order and to prevent minor issues from becoming major failures. In the automotive context, perushuolto is typically scheduled according to manufacturer recommendations and can occur at regular service intervals, such as every 10,000–20,000 kilometers or annually, whichever comes first. The scope usually includes engine oil and oil filter replacement, air filter, cabin air filter, and sometimes fuel filter replacement; fluids such as brake fluid, coolant, and screen-washer fluid are checked and topped up; the brake system, tires, lights, and wipers are inspected; belts and hoses are checked; battery condition is assessed; and a basic diagnostic check of the vehicle's systems may be performed.

For industrial machinery or household appliances, perushuolto similarly covers routine lubrication, filter changes, inspections, and firmware or software updates when applicable. The aim is reliability, safety, and cost control by avoiding unexpected downtime.

Perushuolto contrasts with more extensive servicing or major repairs, which are performed less frequently and may involve replacement of worn components beyond the basic items. While the exact content varies by manufacturer and context, the core principle is proactive, scheduled maintenance rather than reactive repair.
