Suddenly lost almost 100 miles per tank!! I just moves back to Texas from California and my 2000 Z28 is only getting about 200 miles per tank and when i was in Cali i was getting almost 300 miles per tank. Im not sure if my car is tuned specifically for Cali gas by the previous owner either. I have changed the fuel filter and have been running injector cleaner for the past few fill-ups and still no luck. I have had this car for over 2 years now and i always fill up with premium except for the past 6 months or so i had to use regular cause of $$ but only lost about 20 miles or so from that. Now if i use premium it doesn't help at all. Also i have a locking gas cap so no one is steeling my gas. And my spark plugs are only 3k miles old. Please help!
p.s. Nothing has changed as far as how much i use my A/C or my freeway/ in town driving ratio.

there shouldn't be much of a difference in fuels from cali-texas. they're aerated in cali for sure... idk aobut texas, but i believe so.
on the accord, you could probably unhook the battery for a bit and see if that resets the tables well enough to fix it. if so, then you need a new tune on the Z.

LOl catfish you might be right. I guess i could just go ahead and change the O2's cause its a real cheap fix, and it would eliminate that possibility. I am thinking about running an ethanol mix like maybe 10 or 20% to help clean everything out. Im also going to check my fuel filter and make sure that place put it on correctly and is not leaking. I found that when they checked my coolant level they forgot to put the cap back on the refill tank and i drove all the way from cali with it off! Im also looking into getting HP Tuners. Ill try disconnecting the battery on the Honda too and see if that works.

O2's cheap fix Where do you get your O2's?
Everywhere I look they're 70 bucks a pop.
If that were a cheap fix... you've got more disposable income than I.
... then again... you could make that back in about two tanks of gas if you get your 100miles back.

Well guys i have good news and bad news. The good news is there is nothing wrong with my car, and the bad news is that all of Dallas and Fort Worth have been using a 10% or 20% ethanol mix in ALL of the gas here. So everyone has lost about 70 miles per tank. Thats what the guys at the shop said where i took my car. This really blows cause gas prices keep rising and now I have to buy more gas just to go the same distance and there is nothing i can do about it! THIS SUCKS!

I don't see the logic if mixing 20% crap into the gas, to loose 35% fuel economy.
I'd rather pay 20% more for real gas, than loose 35% fuel economy.
(my quick/ghetto testing of E10 here has only lowered my economy 8-10%, but it's still junk)
