samco hoses = contaminated o2 sensor?

[CL Wong]

I saw someone on one of these lists question the
relationship so I thought I'd add my datapoint.

New samco hoses installed this summer.  Figured I'd
replace my o2 sensor because it's been atleast 60k
miles since I replaced it and the gas mileage hasn't
been quite as good as I recall.

Pulled the sensor with my 22mm crowsfoot wrench found
the tip to have a uniform whitish/greyish coating on
it.... hmmmm

Preliminary mileage seems to show a 1-2mpg improvement
over my 90 mile-a-day highway commute.  Looks like it
will settle at 23.5 after a few more days of driving.
(was getting 22mpg with my right foot in economy mode)
