Post up anything pertaining to petroleum gas.
Janizary said:Can we change this to a poll to add range information?
Looks like 12 categories for a poll. Mileage for the polls should be COMBINED mileage. City/HWY would be reported separately in the thread body.
(Yes, there are Si owners that get 37+ MPG, read a few of the ScanGuage threads, or Hypermiling threads)
And THANK YOU, 2FAST!
Sorry, friend, but it can. If you have a scan tool that tracks real time fuel delivery and speed you can easily see the 'sweet' spots for the Si (40-45mph in 5th gear, and about 62-65 in 6th gear). Both can return over 40MPG on a relatively 'flat' roadway. Once you hit over 70mph you MPG drops dramitically. At 80mph you are certainly sacrficing fuel economy for speed. Additionally, cruise control is 'required' for those MPG goals. It can make minute adjustments in fuel delivery to make very small adjustments that your foot cannot attain.spocheld said:I find it hard to believe that an Si could get more than 35 MPG unless you are coasting down hill in neutral for about 200 miles.
WOW, you must have a freak on your hands. I have been driving 40%highway and 60% city and the best I am getting is right at 26 mpg no matter how I drive. I once tried to take it easy and baby the car and then drive it like I stole it but the gas mileage is always the same. Very consistant between 25.5 and about 26.4 mpg. I never took a long Highway trip but I am sure that the mileage on a steady speed will be a tad more but I doubt I will get 31mpg. Maybe 28-29 if I am lucky.BLU BY U said:29-30 everyday driving (50city/50hwy)
31+ when im on only highway on a trip. Best ive got was 32.8
I can see where you got great gas mileage from Vegas to California. That portion is mostly downhill. Even though it doesn't look like it but that stretch between Vegas and LA has a steady downhill slope. The reverse is true on the return trip. I have taken that trip many times and back in the good old days when my rental Car was a Chevy Chevette that constantly overheated trying to go the uphill slope from the trip from Sand Dog to Vegas. I had to pull over at least 3 or 4 times to let it cool off. On the way back it didn't make a peep. Ran as smooth as can be.Janizary said:Sorry, friend, but it can.

I have personally gotten over 38mpg on a trip to California from Vegas, which is inclusive of a few big hills. Given that trip, I feel quite confident that I could attain 40+ should I ever have a road trip across Oklahoma or TX. There are a few other forum members with scan tools that use them when on road trips in their Si who have seen very similar results.
You will never seen that kind of mileage if you have mixed driving (city/hwy), driving in hilly country, accelerate agressively, or drive at over 65mph'ish in 6th gear. This is not, however, what the Si is about, which is why you will normally see about 25mpg on the average, lower if you are scooting about in a spirited fashion. Getting 'hypermileage' in your Si is a 'hobby' or 'challenge' thing for a few strange folks like myself who like to see 'what you can do'. Having seen the results of experimentation, I have changed a few habits that have increased my 'overall' mileage quite a bit, but, as I said, I typically wreck it with weekend bouts of spirited driving.
And, as a point of reference, you can achieve well over 300MPG coasting downhill at 60+MPH out of gear. (Again, scan tools are great...if calibrated correctly)
There are many nay-sayers and non-believers, but those of us who actually have the scan tools to see what fuel delivery is taking place know the truth. It can be done...quite easily at that. But you have to be patient and dedicated. (and be willing to be bored at 63-65mph on road trips)
