slow down.......then you'll get more mpg....

 

I have gotten 33mpg, but that required leaving my car at home and taking my wife's Mazda. If you want good gas mileage buy a Prius.

 

Exactly Thats what i did. Never go above 40 mph on my daily commute. Would never get a chance to enjoy the speed of the 350, so why waste the gas money.

 

I've seen mileage over 30 mpg on the highway, but my current commute only gets me ~20.5 mpg. It's a 20 mile drive about half on surface streets and half on freeway. Freeway segments average around 24, but the surface streets (because of all the stop and go from intersections) averages about 16 or 17. So I end up with just over 20 and call it good. Glad to see gas prices lately - I bought premium at Shell in Atlanta for $2.75 a gallon on Sunday.

 

if watching the bar very closely on the freeway I can avg 29.5 on the freeway in myIS250. In the other thread people said they have gotten something like 32 out of a 350, though

 

thanks for most of the suggestions... The reason I mention the mpg is that I am concerned that there may be a mechanical problem. My car has about
22K and I drive with the A/C on. I drive 75 mph cuz the speed limit is 65 mph and the CHP will only ticket 76 mph and over. At about 15K miles I was getting about 26-27 mpg, but now the number is dropping. What could be a possible mechanical problem. The only difference between my car with 15K and now at 22K is that I have not changed the oil. (i'm using synthetic)

 

No mechanical problem at all. Hotter temperatures outside? A/C works harder and costs mileage. Been stuck in traffic more with school starting up again? Have you checked your tire pressure lately? LOTS of possible very reasonable explanations for your mileage loss besides mechanical issues.

 

not 100% true....they can still give you a ticket (if they are desperate).....

 

truth or myth:

you will get better mileage after you changed your oil ?

 

Damm 250 boiz teasing us about mpg again... oh yea??? well my car goes faster than your car

 

I got 28-29 on hwy. Wait till it goes beyond 10K mark on your ODO.

 

on a recent test

Mobil gives me 25/gal
BP gives me 26/gal
Shell give me 27.5/gal

This is all over at least a 100mile stretch
crusing at 79-80mph

too bad i am stuck with Mobil in my area

 

I wish I was running the 25-27 in my 250, I'm lucky to see the 24 mark and I'm not lead footed.

 

On the highway with the ac on i average 24-26...at about 80mph

 

Sorry off topic but you live in CA w/ budget crunch. Be careful w/ popo. Cop friend told me they will only tolerate up to 5mph over speed limit.
Back to topic, @ 60 - 65 mph you'll get much better mpg. I get 29-30mpg cruising @ 75-85mph. I have a 250 though.
