In this application, the important thing is moisture control. If it gets to full OP temp every time and gets say 10~20 miles runs, OK on good old every day oil. If it runs short runs in the cold, you better rethink what you're doing.
I don't disagree with RK or TSC oils. They're fine. But if it's building up moisture and lots of cold start condensates, then I'd be changing 1/2 way through winter like Feb 1 and definitely staying once a year ...
Heard this before, and not sure I really understood the rationale then either.
If its building up moisture, an oil change will presumably get rid of
most of that moisture, assuming its emulsified into the oil and isn't sitting in the bottom of the sump.
BUT taking it for a run and getting it good and hot should drive off
all (?) that moisture. IF moisture accumulation is completely reversible (?), this seems preferable to an oil change, and there should be an opportunity to do it at least as often as you are likely to do an oil change.
There may be irreversible effects on the engine such as corrosion. These wont be reversed by an "Italian tune-up", but they won't be reversed by an oil change either.
There may be irreversible effects on the oil, most likely acidification and base depletion. These won't be reversed by an Italian tune up but will be reversed by an oil change.
So if you short trip so that moisture accumulation is likely to be an issue, it would seem that a high TBN is especially desirable.
