Hi, everyone. So here's the rundown on my vehicle and commute.

Vehicle: 1994 Mercedes S320.

Don't snear! The car is in penultimate mechanical shape, already gets 22mpg with
its bullet-proof 3.2 liter six-cylinder, and has a 26 gallon tank. The mechanicals easily
have a 150K+ miles left on them, and I only paid $6500 for the car. With a little
hypermiling technique, I'll be much better off than the 1992 vintage SUV I was driving
before. Besides, its darned comfortable.
The S320 has an automatic transmission, five forward gears, and a sort-of tiptronic
feature in the gear shift that allows me to manually gear up to fifth or manually gear
down to fourth at my discretion.
I have 130,000 on the odometer. I have synthetic oil in the engine. The car does
have an analog MPG gauge on the instrument cluster already.

Commute: 25 miles each way, 5 days a week.

I live in a Portland, Oregon inner city neighborhood, and commute 25 miles to a
facility in a rural area outside the city. As I drive to work, I drive 3.2 miles on a
minor thoroughfare toward the interstate. Approximately seven stoplights, speed
zone at a school on the route. The route tends slightly uphill for the first part of
the grade, then slightly downhill to the interstate. My house elevation and the
interstate's elevation are equivalent.

Once on the interstate, I drive about 11 miles on the I-205 interstate, a bypass
around central Portland. Traffic here usually flows at the speed limit, on a relatively
flat grade.

To finish my commute, I drive 11 miles on a state highway - two lane, unseparated
roadway with no passing for the duration. terrain is up/down/arournd rolling hills
throughout.

My return trip is just the reverse.

I'd be appreciative of pointers, for sure. What would you suggest?

The first thing I'd do is set up a mileage log here, and track your progress. I treat everything on a per-full basis, always trying to beat my last tank.

pump uo tires to max sidewall

read 'beating the epa' linked on the upper right hand side

keep a MPG log

try DWL with your iFCD

(BTW - I drove a 1972 MB from 1984 until 2000 - the OD broke at something like 250,000 in 1992 or so - We guessed it had more than 300,000 miles, we we got rid of it - mechanically it was perfect - original engine and original tranny )

Welcome Nojo! You have a very classy ride. I miss my old 1972 280 SEL, with fuel injected (very high tech for back then) 4.5L v8. Very fast, but only 12 MPG :( . Your model gets much better milage. And you'll probably hit the 30 MPG in no time, because these techniques really work. :D Good luck!

PS - Here's a good thread for an overview of hypermiling... http://www.cleanmpg.com/forums/showthread.php?t=1510

Welcome! No sneering here, especially when I roll out the Caddy!

Do the above recommendations and also let that mpg gauge be your guide. One of my very best tutors is my sgii. When I drive the Caddy, I use it's LED (how retro) mpg gauge to help me to glide, glide, glide.

Keep the speed down and enjoy the smooth ride.

Do some cars actually have gauges that show MPG?!

Cam -

Yes almost all European Cars have MPG gauges of one form or another - they vary in accuracy and information - but are useful feedback mechanisms. Some of the Asian cars have them also.

VW/Audi has its version which it calls the MFD (multi functional display) since at least 1996 - It shows average speed, trip MPG, long term MPG, and some other data.

These are by no means as informative as the scanguage data, but for many of us - enough.
