Very Interesting. I just read the entire test. Based upon their results, the point that came across the most was making sure you top off the oil on a consistent basis. Seems the slight addition of used oil "refreshes" the synth and makes it last longer. That and the replacement oil filter really prolonged the life of the mobile 1.

The other point I got from this was that synth really lasts much longer than the traditional 3k. Sounds like we can go 5k 0r 6k easily and not think too much about it (provided the motor is topped-off). The report suggest that 10k would not be out of the question.

I'm actually more interested at this point in a comparison with real oil than in another synth. Wish this could be sped up somehow.
