But I know of 5 others with the same set up and they have not had a problem.

I'm gonna coat the inside of the well including the 5200 bead around the bottom w/a DAPCO latex sealer...should isolate oil from 5200
Capt Pete...I think they don't want you to set the ducer in 5200 which isn't what I'm doin here...it'll be suspended in the oil...the 5200 is adhesive/sealer for the pipe/well only, so I think it'll be OK...
And the ethyl glycol anti-freeze concerns me more than the mineral oil in terms of breaking down the 5200 over time...thanks for the suggestion and I'll use as plan B, but will forge ahead w/ min. oil til it poofs in my face...LOL!!...
