Default 2002 SE V6 80kmi FUEL Consumption

I used to get 25-27 mpg (80-90% highway). Sometime in September I used a
Gumout Fuel Cleaner and since then I get 20-21 mpg. I used to easily get
400-420 mile on a full tank, but after Gumout product I'm lucky when I get
350, but ussully it's ~310-320. I live in NE, but I have used Air
Conditioner since April-May.

My comute hasn't changed, same 80-90% of highway. I've been using the same
oil and filter (Pennozil Platinum) since I owned this car and my tires are
always properly inflated. I was never attached to a particular gas station,
but I always avoid cheaper ones (wawa, valero or somehtng). I've been using
93 for the last 15 years.

What could have happend? What can be done? Car has not had any repars done
since March (EGR Valve).

Thanks.

Correction - I change my oil every 5kmi. Also, it seems like I'm getting not
20-21mpg now, but more like 17-18. I used to get 25-27, because at that time
I used to check it every time I filled it up.

Perhaps you should have used fuel injector cleaner. Carburetor cleaner
is a different chemical. It might have clogged an injector by loosening
debris in the fuel line or affected your oxygen sensors.

Oxygen sensors are very sensitive to some chemicals, so read the can
instructions carefully.

In any case, get a diagnostic readout. Some parts stores like AutoZone
will do it for free.

Can you provide more details? Will $200 computers from PepBoys tell me that?

Thanks.
