What engine oil is best for my Ford Fiesta Classic?

Ford Classic come in both fuel options, there are two engines options, 1.4 TDCI diesel engine and 1.6 Duratec petrol engine. Semi synthetic engine oil 5W30 is best suited for both the petrol and Ford Classic diesel variants. The semi synthetic engine oils do not need to be changed quite so often and make the engine frugal and sludge free.
