I have had a tel ray add n Echo for about 30 years about 20 years ago the echo function stopped working but if I put it on its side it would work. Needless to say the oil had leaked out of the can. I did some research and tried using some light weight sewing machine oil but still no echo. The motor drive works and all the other functions on the box work. Anyone have any experience fixing these things? Wondering if I need the $65.00 a pint UC oil?
