Oil question, but not what you think!

[Agrajag]

Dear UKGSer,
Today I changed the oil in my fabulous, yet surprisingly modest GS. As usual I went for a quick spin to warm the oil up to make it drain more easily.

However, I started to think about this. As the oil grade is 15w 50, surely it gets thicker as it heats up? Have I been doing it wrong all these years? Would it be better draining it when cold?

Dear Confused of Glasgow,

Next time wait until the middle of your lovely Scottish winter to test your theory, might I suggest a particularly frosty or snowy day?

There's your problem.
