I run two vehicles with 1.5dci engines and am interested in the long term effects of using cetane boosters such as Millers or premium fuels which also claim to have a higher cetane rating. Is any benefit short term as in it's great for a few k then the engine will suffer from premature wear or failure or are these things good for long trem ownership? No real help from the fuel companies or the makers of additives, naturally.

These engines have got knock sensors, so anything that makes them run more smootly might show a marginal power increase.

As to long-term harm; you give us a detailed run-down of what's in them......

exactly. . . who knows the exact constituents of snake oil and as for these premium fuels unless I have access to a mass spectrometer and n.m.r. machine i would not know.

These fuels and additives also enhance lubricity so cant be bad IMO.

Typical diesel clatter is "knocking" modern diesel incorporate knock sensors to optimise injection timing to minimise knock and hence improve refinement.
