Calibre Formula 40

oils aint oils – Calibre oils are highly recommended, Ive used calibre for years in standard and high performance engines purely for reasons , come the 10,000 oil change calibre still retains its clear colour, no black, no burn off,no break down of viscosity..? i would recommend Calibre oils to all types of vehicle owners and its affordable....

Good as gold for normal usage – After all it's made using ths same additive packs as everyone else. Those complaining yhave no idea what they are talking about. If this had another lable on it would they would rate it higher? Anyway would Caltex, who blend it, make a crap product? Doubt it!!!! Economically priced.
