Touring hot countries.
At home it's changed to 15/40
As Andrew says 15-50 does the same job for winter and summer and unless you buy cheap supermarket oil is not really any more expensive it helps with cold lubrication.
Even if you change twice a year and use cheaper 15W40 in summer it's worth using 15W50 in winter as 20W50 is seldom much cheaper.

Yes I undetstand that.
The thing is when using 15w/40 I get an annoying oil light flash after a high speed run and then slow traffic in +30 deg heat.
The gauge tells me everything is fine and I have 14psi
Does not happen with 20w/50, gauge reads 18psi
Fit a new switch I hear you say, well I like to change the 'summer oil' so there.

15w50 will be rid of te oil ligt just as 20W50 will it's the 50 bit thats important but the 15 bit helps reducewear cold better then the 20 bit.
