Pistons, connecting rods, also to a lesser diploma, crankshafts have all been updated with lighter body weight design and style. The excellent news is usually that it remained an iron block- the engines have been still on sound Basis for weighty and major modifications.
Not always an O2 sensor fault there, but it was quite very clear that it had the capability to make an honest influence on gas financial system dependant upon how it unsuccessful. 7.5L/100km is a fairly damn fantastic figure even though so Evidently in the case it was not hurting your situation A lot
