first time on here so bear with me
have 2000 legacy outback....had it since new
has 111,000 miles
had mpg prob 2 yr ago and was told nothing was wrong .....when i got home from the dealer i had a recall on the O2 sensor......fixed the prob.....but has been slowly declining in mpg for awhile.......did a tune up and put new bosh plugs in and K&N filter.......lost 3mpg........Just got done replaceing my leaking head gasket and put a std. airfilter back in to see if that would help .....didnt do much...........anyone have any experience or ideas

but don't neglect the simple things, ie; tire pressures... have you changed your tire brand/size recently? winter tires and wider tires will effect your mileage as well

I've got a '99 with declining MPG -- I suspect the O2 sensor -- and I've been looking for info to see if there was O2 sensor recall for '99s.
Can you send me a URL to the information?

I changed the front O2 sensor in our '99 for about $50. It's very easy to do.
I would replace the plugs and air filter with OEM parts and go from there.
