The important part is to keep the oil inside the motor. When the motor starts up at the surface, there is significant centrical force that pushes the oil out with the seal in its original orientation. I should actually remove one of the seals and just have one seal holding oil in, just like a submersible well pump has. Those pumps are VERY reliable.

<DIV>Hi Carsten, </DIV>
<DIV> I did a small test trying to light the WD40 on fire. It's not as flammable as I thought it would be. I think they have improved it's non-flammability with new formulation. It's still somewhat flammable however. </DIV>
<DIV>I will be using a light mineral oil in my motors.</DIV>

<DIV>I just ran one of my motors filled with the WD40. It seemed to be very happy. I mainly just did it to clean the carbon build up out of the motor. I was surprised how sealed the motor was, it is open at one end where it mates to the gear box. I was able to fill it up without it leaking out anywhere. That could be an issue later when I want the mineral oil to fill all the voids. I might need to actually drill some holes to get some circulation . </DIV>
