Default so attacking my o2 sensors... and something came to mind

my mileage started sucking after sea foam. Is it possible that the 02 sensors are caked in **** from doing the sea foam? Anyone else experience this

Default I figure about one year ago when I drove 225 miles on a 1/4 of a tank, and now I go a little over

120 miles on 1/2 a tank, something's not right. All I have left to help improve my mileage is O2 sensors, fuel filter, and an alignment.

BTW, I didn't have my chip a year ago.

Default is there a way to test the O2 sensors to make sure they're working efficiently?

I know mine work because I get a CEL with the test pipe in, but does that mean it's working optimally? Are these either working or not working or is there a middle ground?

VAG-COM maybe? I just have no record of them being done in 140k miles.

Yep - there's a block to test for 'aging'

care to elaborate? I just bought an o2 sensor, but it'd be nice not to have to replace it
