could it be it does not factor in idling fuel used ?

Ever have an evap code? I don't think its good practice to fill up so far.

probably...my dash is lit up like a christmas tree ...
actually the last code pulled was for the rear 02 sensor. i changed the upstream although it wasn't giving a code, hoping to maybe increase fuel mileage...which it didn't...then a few days later i got the codes cleared and a new scan when the ses came back on and it's pointing at the rear O2. i thought maybe it had something to do with that royal purple max clean i just put in. i already had a new sensor. i was just waiting to install it with a new downpipe.
anyhow i fill it up all the way so i know the next time i fill up exactly how much fuel it used. if you just go by when the pump nozzle shuts off that's not accurate. sometimes pumps kick off when it's not even filled up, so you know that's not accurate .

Yeah, but you have an evap valve at the top of your fuel pump canister. I don't think you want to be pulling raw fuel through your evap system?

Why did they ever stop calling it gasohol like in the late 70s? I thought that word was cool.

We should just go to like a 91 Octane standard for regular gas, would make things much easier.

Yes it would make things a lot simpler if they just offered 91 octane and e15 and e85 and call it a day.

Pretty much.


Third rule of rednecking: if it's liquid it can be drunk'n (drank? idk), even if it kills you.
