Denso lead resistent O2 sensors

[RedGTS]

Anyone know anything about the new Denso "lead resistent" O2 sensors?

Apparently they came out a few months ago and were supposedly tested to show 2 times more resistance than other sensors. Of course if the stockers would fail on leaded gas in a week the fact Densos would last 2 weeks wouldn't be a big selling point. Sure would be nice to be able to hit the 110 leaded pump near my house.

Sunoco makes unleaded 105 & 109 Octane fuels, probably marketed under their Cam2 lable.

I think Sunoco and Union 76 both make 100 unleaded as well, but there isn't anything around here at a station other than the 110 leaded.
