"Cold" oil change
So, I decided to break with accepted wisdom last week and change my oil cold. Gasp.
[Note that “cold” at the time meant an ambient temp of about 18 C / 64F in my garage.]
Here’s how my thinking went:
The day before the change I had parked the bike after a 250km trip in 20deg C temps at highway speeds – so the engine was, shall we say, well warmed through. As a consequence, I thought, the hot oil will have drained down to the pan, and will all be sitting in the bottom of the engine.
Starting it, I reasoned, would only send the oil back up into the engine, and require it to warm thoroughly and drain out again.
The only downside to the cold change would be the lack of viscosity at the time, which would require a slightly longer drain time, and leave a thicker residue of the older oil inside the pan.
The upsides were a cool engine and cool headers to deal with – seemed like a fair exchange to me.
Have I missed anything?
