--W124's MPG Thread--
 

Hey everybody i was just woundering how is everybody doing with thier w124 and the MPG.. am sure people will be different here as some have V8's but lets see whats up in gerneal from everybody....

first of all am trying to figure out my own mpg lol,
last time i put $30 and it was 3.36per galon Premium and i've gone 135-140Miles with that which i think takes it to like 17mpg or someting? is that true..

(((((((((and what is good too Increase your MPG))))))))))

I check mine everytime i fill it.

Depending on how hard I drive, I usually get between 16-19 MPG

Not great but it could be worse...

i see... well i've never actually filled mine full lol but i think i am going to do that and see how i do on a Tank

I get about 15-18...because I drive like a total jackas$ lol

It makes a difference.

I was broke as hell starting a new job in Nov. and I was putting in $5 every day just to go to work and back. (about 15 miles)

Now I put in about $30 a week to top off from half tank and I drive a lot more than just to and from work.

I usually see between 18-23 around town.

so what i think your saying is that if you put less gas than you wil get lower mpg?

It sounds illogical but Im sure theres a reason for it.

$5 a day for a 6 day workweek = $30 for about 90 miles.

now i do $30 a week and get about 140-150 miles.

Anyone have any suggestions as to why?

i dont have any suggestions but it kinda makes sence thoo

I drive till 1/4 full, refill and repeat. :D

I get around 400km/tank in the city and almost 700 on the highway

soo 400km equals abut 230miles and thats on a FUll tank?

and how many galons are on that 1/4th lol

I drive until the light comes on, usually at between 325 and 350 miles. I check my mileage every time I fill up, which is about every 4 work days. This morning I computed 22mpg for my last tank. I usually am anywhere from 21 to 24. My fill up is usually between 16 and 16.5 gallons and right now that's $48 to $50.

berti, the way to get the most accurate MPG is to fill a full tank of gas, and reset your trip meter before you even start the car. drive til the tank is running low, and then fill up the tank completely again. then you divide the mileage on your trip meter by the gallons of fuel you just filled up displaying on the pump.
if you do it like this, even if you fill it up full from half tank, you'll be able to see how many MPG's you're getting.
1/4 on the dash is not really 1/4 of the tank, so you will never get a true reading if you try to calculate it like that...

Before I got my exhaust on I would normally get 210 miles to 260 miles (depending on how i drove) on 11 or 12 gallons of gas. I fill at 1/4 as well just to be safe. So since I got my exhaust I'm looking at 210 miles max. Somehow I went from 21-23 mpg to 18-20. I've heard that high flow exhaust will make your car run rich so my question is this: can I compensate for my bad mpg by adjusting that little screw on the throttle body? (leaner of course) What are the signs your car is getting more fuel than it needs?

DITTO!

haha thats how I do it.

Like I said tho before I was low on cash so I would put 5 in every day but the lights wold ALWAYS come on right when i turned onto my street. I drove the same path to work every day.

I Let Mine Hit the Reserve Line Before I Fill it

My 260E Gets About 450-500k's Around the City, And Highway Driving i Can Push her and get 750-800, I could Probably Push her a little more But Id rather not be left stuck on the side of the Road with no Petrol.

Though Ive noticed When i used my Cruise Control on the Highway she Uses HEAPS more Petrol, i might get 400 if that with highway driving. :nix:

is this on a ful tank

Yeah This is on a Full tank

how many mile is 450k around like 230?

Nah its around 280 miles i think

23-24 Mpg

depends how much im driving like an ass.

I fill up at the 1/2 mark. Just me.
I get 300km when I'm at that mark, i.e. 185miles. The first bit from full tank gets me 93 miles. :D
I baby my 124 and I have a tiny little 2.2 engine. :rolf:

I will get just over 24 mpg (24.4-24.6) on the highway and usually just over 20 if mixed city/hwy. I got about the same milage in the convertable as well.

I had been strickly a 93 octane user, but I talked to my mechanic and he said I could try the 89 and just make sure it doesn't ping. I am on my second tank of 89 and the milage is the same and no-pinging.

what does that mean no-pinging?
