This should be fun.
 

Hey everyone.

I drive a real guzzler, an Infiniti I35, and I love this car, and I think it'd be fun to get as much out of it as I can...

Welcome to the site. What kind of mileage are you currently getting out of it?

According to the onboard computer, I can get about 28-30mpg if I only drive it to/from work. My commute is 90% freeway, so this can be easy. Overall, I can get about 26-27 now (again, according to the built in computer)

For me, it's more of a challenge to get this guzzler running decently. I'm already exceeding the "new" mpg estimages and would love to see how far I can go.

Part of the problem is I'm also extremely upside down on this beast, and couldn't get rid of it even if I wanted to...

I'm sure there's much improvement that can be had with the car. What's your baseline look like?

If I drive like a "normal" driver, not using any hypermiling techniques, its about 24-25mpg. I can get up to almost 30 just by some basic hypermiling. Best I've ever done was about 37mpg, but that involved a long, emergency trip to my mother-in-laws, when I was short on cash, and ended up drafting behind a truck most of the way.

Right now i'm testing to see how accurate the onboard computer really is, so we'll see if I'm actually doing as well as I think i am...

Tire pressure!
 

Pump those tires up hard! The difference in rolling resistance (RR) is tremendous ... and this is free!
Recall the last time you had an air leak in a tire. The car pulled to the low tire side, yes? This was a greater rolling resistance showing up. If you go the "other way" ... increased pressure ... the tire rolls easier. A pressure in excess of 40 psig would be a start.
Less resistance...less gasoline required ( more MPG). Hey, this ain't rocket science....N2 is not required. :cool:

nitrogen -

Welcome to EM! It sounds like you're already honing your driving techniques. It didn't occur to me until Whitevette pointed it out. You should do the Nitrogen filled tire test!!!!!!

I am seriously considering a scanguage II to help me with my driving techniques. I seem to do VERY well on the freeway, but in city driving, I suck.
I had to do lots of city driving today, and I went from 28mpg to 25 today.

It might just actually be the car, but I am wondering just how well something like this can help?

Okay. The built-in MPG computer in my car is a piece of crap, and a huge liar.

The computer said I got 26.1. The math I just did on my last fillup said I did 22mpg.

:confused::eek:

It's always good to cover the basics first!
Tire Pressure, Air Filter, Oil/Filter Change, Remove un-needed weight (subwoofers, luggage, etc.)

You'll enjoy your new ScanGauge, once it's calibrated it is AWESOME!!!

Good Luck!
