How to Improve Gas Mileage in W140

[s500lang]

When buting new tires choose the smallest ones and I think thats 215 for w140. This will reduce road friction and decrease fuel consumption. I have 225 all around.

Picture me Rollin in my 500benz car been legendary since 2pac, there were just lucky gas prices werent off the roof now its a luxury to have a car just to afford the gas..........But like all of you i still love the W140 nothing compares

[W140FTW]

In mainly city driving, I average 17.5 mpg in the S320. The lowest I've ever seen...in city in the middle of winter, was around 15mpg. Needless to say, it's awesome for a 4500 lb car. My 3600lb deVille would hardly ever get better than 15.5 in city. On the highway, I've seen 23-25 mpg mainly.

i'm all city driving in central jersey unfortunately so i usually get around 16- 18mpg on a good week. Too many cars too much traffic X(

But considering the weight and class of the car it doesn't do too bad when cars that are no where near its size get the same fuel economy.

well then you better plan on hating it more if you get a 5 or a 6...my 6 got 13.2 MPG the other day in the city but she averages 17 to 20 on the hwy unless some stupid BMW wants to run and then its right back down to 15 mpg

Flossin a Benz on rims that isnt stolen

That car He was referring to was a R129 500. Pictured in his garage with a Corniche. Also seen in the videoTo live & die in LA.

One 2pac song that would work well with some Benz owners here is Troublesome 96

Pump up those tires! not 27 oem but 35 psi. The ride will be slightly firmer. Rolling resistance will be down considerably.

Life on an outlaw...any Pac song is good for cruising but yeah the tire presurre does make the car roll easier i would say its one of the important things along with other friction

If you are getting bad fuel consumption 02 sensors are the things to check they adjust the mixture based on a reading from the cars exhaust, a good way to check is to simply unplug them for a while then the car will run on what is called a closed loop setup and see if the consumption improves they may either be giving a false reading in which case consumption should go down or something else is wrong.

A certain Ludacris song comes to mind, most likely guaranteed to get a few dirty looks specially if stuck in traffic.
