Gas Mileage
So I know every winter gas mileage gets worse but, has anyone noticed a significant drop in gas mileage?? Granted I have been taking advantage, more often than not, of the nice cool air, but not enough to yeild 230-250 miles to the tank. Also its about time for an oil change and I know my car gets much better mileage with a fresh oil change, but again not to that extreme. The third and final variable is my tires and struts... The tires were so bad if you took a quick look you would think i was running street slicks, and the struts were blown badly and if youve seen my car you'd know why.
The new tires and struts are getting installed as I type this, and Ill be getting an oil change Sat. morning, but are those variables really enough to push my mpg that low? I was averaging about 320-340 miles per tank this summer

Maybe all of them togehter possibly could result in that kinda mileage
What kinda driving you been doing though? I usually get about 200 miles before I fill up and average about 17 mpg but thats harsh driving(start car drive, 3 miles to school, turn car off).
YOu should wait and see what happens when you get it back. If its still way off, then check to see what it could be. I remember a few threads where something went bad killing the gas mileage, but those were awhile back and I forget them exactly.

Even in total stop and go for 30 miles, I get 23......I average 25-26 mpg with a mix of city /hwy commute.
Damn.

17mpg?
17mpg is terrible!!
I just sold my 1997 3.0CL with 169k miles on it and for the 120k miles i put on it i was averaging 25.5mpg. Last week I bought a 2003 type S and my mileage was 22. I was very disappointed, especially since now I have to buy premium gas. I was hoping it would get better, back into the 24-26 range.
What is everyone else getting?

Did you people not read what I said?? THe car is barely warmed up by the time I get to school. I'm not expecting to get the best mileage with that kind of treatment. In normal driving conditions the milage is fine. Hell I've got 30 mpg on the highway once.

17.2 gallon capacity - 3.5= 13.7gallons. 350/13.7= 25.5mpg. That is more like what i am hoping for in my gas mileage.
where do you all buy 91 octane gas and if you arent putting in 91 what are you putting into the tank?

I bet I am not getting much more than 20 mpg with my six speed. It must have something to do with the 3500-4000 rpm shift range that I typically use!!

Mclaren: I know you have no control of the distance of your drive to school, but you are doing your engine possible harm. Consider this. The valve train for cylinder #1 will be on a different schedule than the rest of them. If one cylinder has all four valves closed, there will be some where the intakes are open and some with the exhausts open. At night temperatures cool. Drastically if your car is left outside in winter. Moisture will enter either either valve path and condense, ultimately leaving a small, but still some water in your oil system.
It is prudent to run your car long enough to evaporate that moisture such that internal engine corrosion does not get a foothold. Agreed, most of the really important parts in an engine have some oil on them, but trust me, water is insidious. In the corrosion world, we call water the "universal solvent". Depending on what form water takes (ice), it can split boulders in half.
My livelyhood involves paints/powder coatings and corrosion testing.
This is not fatal on a daily basis. At least once a week, find some excuse to drive the car for a half an hour or so. Let the oil get hot enough to drive off the water. I once ran across an airplane I wanted to buy, and I had my instructor look at it. 25 years old (young, for an airplane), but only 400 hours on the engine. Although the ship was in fine shape, Ray advised against me buying it. The engine was not run often enough and internal corrosion could be an issue. For a teardown of the engine to find out, it would have cost about $7,500, and that was a decade ago.
Causes of poor gas mileage include, but are not limited to, low tire inflation, lead foot, car out of allignment, dragging brakes. I typically fill up around 300-325 miles in around town driving. And the best road mileage I have got was 31 mpg. Remember, this is a heavy car.
Getting into sixth gear as soon as possible helps. The CLS6 is just as comfortable in fourth gear as in sixth. But in fourth, if you dont notice it, the gas consumption increases by about 1/3. If you have an automatic, disregard. And I shift around 2,000 rpm.

Thats why I like to take trips on Sundays
(work the rest of the week). I know what water can do as well. We have an old dodge pick-up in our auto shop at school and it sat out last winter and had no anti-freeze. Needless to say the block practically split in half.

i get about 18-19....and that's almost all city driving....about 2-3 miles one way to work. but i do drive throughout the week here and there.
but my alignment is slightly off and need to get one....plus my tires were worn and i just put a new set on a week or so ago.
but when i take a long drive, i get about 27-28.

I just refilled my 2003 CLS yesterday. I drive in 95% stop and go for about 4 miles and maybe 1 mile of driving at about 45. I recorded 239 miles when the gas light came on...all I have done to the car is a k&n filter...what's up with that?!?

instead of tracking mileage by tank, reset your trip gauge next time you fill it. then the next time you stop for gas divide gallons to fill into miles driven. unless you are running from full to bone dry how many miles you drive is not a good way to determine gas mileage. the tank is 17.2 gallons so 239 is about 14, pretty low.

is shell v-power 91 octane?
i ask because when i drove my 1997 CL initially i put premium fuel (93) in it. then i read the owners manual and it said to put in 87 octane so i did. after i made the switch my gas mileage actually went up about 2mpg. the '03-S wants 91 octane but sunoco and exxon sell 89 or 93. i wonder if i could get 91 octane if that would make for better gas mileage.

i have been looking for 91 octane here in NJ where i live and i cant find in anywhere. exxon, mobil, sunoco, shell, valero, and local independents all sell 87, 89, 93, and sometimes 94. i have never heard of 76. i will try different gasses until i find something that works. does sucks to pay $30 to fill the tank though.

You won't find 91 on the east coast. The 91 is something out west, I believe related to emissions. I use 93 all the time.
I was getting about 26-30mpg on mostly highway driving. I put new tires on and my mileage has gone to 24-26mpg, most likely due to stickier tires.
