Prima product
Ik heb een oudere auto met heel wat kilometers op de teller. Door slijtage was er frictie tussen verschillende motoronderdelen. Ik deed een blikje Mannol in het oliereservoir terwijl de motor nog warm was en sindsdien voel en hoor ik het verschil. Door de hogere viscositeit verbruikt de wagen nu ook beduidend minder olie.
