This is a very good idea. |
Are you checking the oil exactly the same way each time (level ground, fully warm engine, 5 minutes after shutting off, etc.)?

I was always taught to check oil on a level surface and a cold engine.

Digging around, I've seen .0004/deg F as the thermal expansion coefficient. For a 140f rise (40f to 180f), and a 7 qt system total (??) that's 40% of a qt of expansion.
Given that the oil temp is likely to be nearly the same (within 10f) every time on a 5min after shutdown, vs. the >100f swings in ambient during the year that some places have, it makes sense. Of course, one way to deal with that 1/4-1/2 qt of change is just to keep the cold fill point at 1/2 qt low, since they so nicely provided that mark on the dip-stick. Although, one could also time your shutdown wait with how long it takes to fill a tank fully up. |
