The oil pressure is about 90 pounds at start up but then as it warms goes down to about 30- 40 pounds. Runs pretty good, no severe smoke. Just doesn't seem to go too fast. I have a 190D with the OM621 engine which runs very well as a comparison. So its not like I don't have diesel experience! This is my first time with the OM636.
Any thoughts?
Thanks Angus

The OM636 is a slower engtine, all things considered with a top speed about 60. It's a push rod engine unlike the OM621 OHV engine which has greater displacement and higher compression.
Both engines will easily drive to Jupiter if you have enough fuel and oil, but the 636 will take a lot longer. That said, it's like the Mercedes 260D --the first diesel-- did the job for its time.
