Professional Car Service & Repair
in Vantaa — STG Autohuolto

The stability, drivability, tire wear, and your safety depend directly on properly adjusted wheel alignment. Often, misalignment cannot be detected visually — the deviation may be very small, yet it can still have a significant impact on the car's behavior on the road. Considering the condition of roads in Finland, we recommend having your wheel alignment checked when changing seasonal tires, if the car pulls to one side, when steering feel changes, or after hitting a pothole or kerb. At STG Autohuolto, we use precision measurement equipment and adjust wheel alignment to the manufacturer's specifications — ensuring safe driving, better handling, and longer tyre life.

Oil should be changed regularly, as its properties deteriorate with use. A common recommendation is to change the engine oil every ten to fifteen thousand kilometers or at least once a year, whichever comes first. The oil change interval depends on driving style, driving conditions, the age and technical condition of the car, as well as engine and manufacturer recommendations. The transmission oil change interval is usually longer, ranging from forty to one hundred thousand kilometers, depending on the type of transmission and manufacturer guidelines. Regular oil changes extend the life of the engine and transmission, improve vehicle performance, and help avoid costly repairs.
