Volvo D2-40F Engine Oil

These have been discussed many times before, but an example which springs to mind recently was when I checked my oil a couple of weeks ago. It was last changed in 2015 and after 50-odd hours is still dead on the full mark and still exactly the same clarity as when I changed it, such that it's not easy to see the level on the dipstick.

Whether the lack of any black carbon breakdown deposits in the oil is particularly important in the scheme of things, I know not. However, given the small additional cost, I would rather have clear bright oil right up to the time I change it rather than the "traditional" black diesel engine oil which others seem to be happy with.

I'm back on the boat again after a few more hours using the engines so I checked the oil before starting:

The starboard engine oil looks exactly the same and I still can't see any difference in colour between this semi-synthetic now and when I poured in it 2 years ago. How important that is is a personal judgement, of course.
