Ok here's an odd one, well for me at least. Brand new Roma run a rear bearing. It would have 1/2 a gallon at most through it.

Not that I suspected anything but from the get go I was a little disappointed in its performance. I had one club day at our track then took it out and went back to the P5. Decided to put it back in and try it again on our home track. After a couple of tanks I heard the dreaded sound of a bearing. Of course by the time you hear it it's too late. The thing is toast. Mildly disappointed to say the least.

I doubt this is common but I would be interested to hear if this has happened in the past.
