Amoco,one of the nation's largest oil companies,has been forcing a number of its independent service station to convert from full-service stations offering repair service to convenience stores or gas only station. Thus the highly profitable repair part of the business will no longer be available to those station owner forced to convert. The franchised independent dealers have little choice but to give in to Amoco because the oil company typically owns the station's land and building and offers leases of only three years or less. This arrangement appears to vest all of the power with the producer and virtually none with the dealers
