That you need not do so - fine, that's what I thought. But "should not"?
Why is that? That wasn't stated in any of the previous threads.

Again - why not? That was also not stated in the the previous threads.
Clearly, topping-up with a lower grade will gradually degrade the
quality, but why is synthetic topped up with semi-synth worse than all
semi-synth?

Yep - I'd worked that one out. ;-)

Never asked my own dealer what he uses - I've made a note to do so.
Until recently my 146 only used about half a litre between services, so
it didn't seem of crucial importance. It still uses less than a litre.

Sorry that you think it exaggerated but my error was to suggest the
search should be on Selenia. Try Oil as a subject too, and see the
answers to the other questions you raised.

Ah, that does indeed make rather a difference! ...

... however, after the best part of an hour's reading I am none the
wiser as to either why one should not use synthetic oil (the archive
seems to give more pro- than anti-synthetic posts, though precious
little in the way of actual evidence either way) nor why synthetic
topped up with semi-synthetic is worse than all semi-synthetic. Could
you cast some light?

Personally, no. I am not an engineer.
It appears that the Fully Synth "burns" quicker than Semi-synth.
Adding semi-synth to a fully synth oiled engine would mean that you
were adding "good old oil" to an engine that had not used it before.
If the car had always been run on semi-synth then all the parts will
have meshed together to run at the tolerances that the semi allowed.
There certainly were many cries of "my 156TS is burning oil". When
people were pointed toward other equally modern engines from other
marques there did not seem to be much difference. Still the fact
remained that a significant number of owners appeared unhappy with
the frequency that they were having to top-up the oil.
It did seem as though possibly the suggestion of changing the oil to
Semi-synthetic was to address this issue. IIRC this was around the
time of the change from the TS to the JTS.
My own experience was that (as expected) my new TS engines did drink
a fair amount of oil for the first 5-10K miles. Since when there
didn't seem to be the need more than a casual eye.

It may not be strictly relevant but I use 10/60 in my quite highly tuned 75
V6 . I buy Miller`s Oils - fully synthetic - and I don`t think the price is
unreasonable . Certainly less than Selenia and vastly less than Agiip .
The 1750 will soon rise again . Until it brakes - again .Phil
