There are three key reasons why the transition to synthetic oils is occurring. They are the proliferation of smaller displacement turbocharged engines, escalating CAFE fuel economy requirements, and government regulations to lower tailpipe emissions.
Ford Motor Co. has approved three Shell Rotella heavy-duty engine oils for its diesel-powered Super Duty trucks that meet the API CK-4 specification, Shell has announced.
Ford is recommending the use of a new Motorcraft diesel engine oil for its Super Duty trucks and warning fleet and commercial customers to avoid using most new CK-4 or FA-4 oils because they may cause damage to the engine, the company told AutomotiveFleet.com.
With engine oils meeting new CK-4 and FA-4 category specs on the market, fleets need to know how best to make use of them.
The program makes Pennzoil and Quaker State motor oils and Shell Rotella engine oils available to the Bridgestone Affiliated Retailer Nationwide Network.
