There might be a chance everybody is right but some are not that accurate. It all depends on how you do the mpg calculation, to be specific how to measure the gallons input. My measurement was very exact (being an engineer) but it sounded like some people just estimated the gallons input therefore the result was off the chart. It does not take much error to arrive at 29 - 30 mpg.

Like Jewcano said, nothing to win here, just sharing the experience. In mixed city/highway driving, I average over 21 MPG. I try never to floor it, and do my best to coast to lights that are going to change up for me to green and do minimal braking whenever I can. I know the cars are only "supposed" to get 20-25K out of a set of pads, but I get much more because of my driving habits. My old car had a set that lasted 60K and I only changed them because I figured after owning the car for 6 years I should change them out
. I had done the basic maintenance with fluids, but the pads were replaced with probably 15% wear left since I had everything and it was pretty easy.Big Mack

Used to be the case, but with today's modern EFI and electronic ignitions, it's actually better to turn the car off if it's going to idle for more than 1 minute. Now, I'm not sure how this applies to the 2GS, given that even the youngest ones are approaching 6 years old right now.
I do know that the electronic ignitions in the car are very similar to what is on the market today, so it may apply to us. For me, I'm not doing it. I have a remote start on my cars for a reason - I want my AC nice and cool before I get in!! Living where it is 117° is a little bit crazy, and I'm willing to run the car for a minute before I get in so I don't burn my *** when I sit down.
And yes, hypermilers can be incredibly annoying and dangerous. I saw one in a little crapmobile tailgating a semi. I'm sure he was impressed - until the truck called his buddy and they played with him. If you've not experienced this phenomenon, I don't suggest trying it. If they line themselves up just right, then put the car in between in the crosswind by misaligning the draft, it can pick a small car's front end up and bounce it around a bit. I have a friend who drove a mommyvan that did this. Imagine the look on his face when his pants went from tan to brown as the front end (and drivewheels) lost contact with the road. I don't know what it looked like, but I bet it was hilarious. I know he'll never tailgate a truck again.

hmmm i still wanna call shenanigans when i see gs430 owners post these #"s
i drove my car back from Atlanta at 2,400 rpm the WHOLE way just to see what my mileage was. i got back into Memphis at about 390 and the light had been on for like 40 mins or so. only stopped once and wasn't running the a/c, NO back seat,NO trunk interior, and on stock 16's and only got mid 24 mpg. i got new plugs, clean TB, clean air filter, fresh nitrogen, newly rotated tires.... with no interior in i was def lighter than most but STILL couldnt muster 25's although i got close so unless u drove ALL downhill i would have to see it.

On a vacation trip last year I avg over 28mpg, closer to 29mpg on the first tank which was 99% highway and I recorded the exact amounts of fuel and calculated it, I did not just estimate it. I basically wanted to see what the best realistic fuel economy I could get on the highway without resorting to driving really slow or shutting the car off when stopped so I over inflated the tires to about 37psi, did not use the AC, kept windows rolled up, used cruise control most of the way but when not using cruise I drifted downhill as much as I could, and kept speeds under 70 as much as I could. There was little traffic along the way. I had used a fuel injector cleaner about a month before the trip and have cleaned my throttle body and mass airflow before. I was pleasantly surprised but not shocked by over 28mpg. I avg around 26 mpg the rest of the trip. It is possible to get good mileage with cars that don't normally get great mileage on the highway by adjusting your driving habits and having the car in top running shape. In stop and go traffic my mileage drops significantly and that is where you know you have a v8 under the hood.

No, it's 430 - it's 372 from center to center (meaning downtown Hell-A to downtown Phoenix). I'm 30 miles from there, and I drove 30 miles the day before I left, so 372+60. I drive a 430, not a 300. I did have the AC on, but I was doing 110 mostly on the downhills, so there was some aid there. Either way, no shenanigans. I was floored by it myself, to be honest. I couldn't believe I cruised into the gas station right around the corner from my place and only had to put in that much fuel. I run 91 (it's the best we have out here, unfortunately), and at that point was getting my fuel from QuikTrip. I have since switched exclusively to CostCo, and have noticed no difference in performance even with a heavier wallet due to the savings.

I might want to try that MAF cleaner sometime and maybe TB cleaner see if that could yield me some better MPG. However, like they say, why fix what's not broken. I might risk breaking it thus nullifying the cleaning and any savings I'd have otherwise.
