 In 1966, the company changed its name to Teboil, which came from the pronouncing of its abbreviation TB with addition 'oil'.During these years, the Finnish government enterprise Neste held a legal monopoly in the wholesale of oil products, thus also Teboil actually obtained its petrol and diesel from Neste.There is some evidence that Teboil kept tank fuel reserves, in the case the Soviets would invade.
