mpg help
hey guys i've had my ls since march and im astonished that it has the worst mpg i've experienced, i was just curious to know if anybody has experienced using a certain type of motor oil or a certain type of gasoline made a difference, any other tips, feel free to mention them plz

My previous cars in the past were pretty quick and got decent mileage. Since I got the LS, I realized if I drove the same way I did with my previous cars, I would get about 12 mpg at best. So now I gradually coast my car up to speed. I like to compare it to Bowser from Mario Kart. I start off slow but eventually gain momentum. Since upgrading to 22" wheels, my MPG has gone down a bit as well.

thats probably the best ill get in the city too, but normally its 7-9 which is crazy, my escalade did better than that, that had a 6.2 liter v8 with 403 hp and also had awd, i would hate to have to alter my driving habits so much

I cant complain I get 18 in the city and getting 27 on the highway

Mpg
It is all about the foot on the accelerator. I drive fairly fast on the open road, but around town and stop and go traffic I take it a little easier. In town only- 19, mixed driving, 23.5, Interstate or anywhere I can use cruise control I easily knock down 27. On one trip from Delaware to Central MA. I hung right around 30. I usually drive 10 to 15 mph above posted limit, except in towns. In Delaware there are local cops in all the small towns just waiting to jump you so they can fill up the city coffers.

Here are some things I suggest to get better MPG.
-Change your driving habit if you drive aggressive. -Reset your cars ECU so it can learn your driving style vs the previous owner -Check your tire pressure for correct PSI. -Check all four tires for uneven tire wear. -Check your wheel allignment and toe specs. (Either one will eat gas but the bad toe will eat tires quick) -Check engine air filters -Check spark plugs (Have they been replaced or is it time) -(Flame suit on) Use premium gas if not already using it. Last if you are riding on bigger wheels than OEM your MPG's will drop but not to single digets you should be getting above what you posting if all is in order along with a reserved driving style. |
mileage...measure actual or trip computer
just curious as I read this......are these actually measured and computed or are they from the trip computer? I have been wanting to check mine and compare to see if results are similar....or are there those of you who have already done this?
I live rural and little 'city driving'...I get about 22 avg overall and 27-28 on 100% highway[trip computer]. 2009 awd/swb Mike |
I usually get between 18 and 20 mpg around town and at least 27 on the highway. Our city traffic here in Tucson is lighter than places that have regular traffic jams so I may be getting a break there. Freeway limit is 75 and I usually set the cruise to just over 80. My trip computer read-out is consistently about 2 mpg optimistic on the highway and pretty close around town.

As we speak my car is ironically at lexus and i asked them if they could tell me if i should replace them or not and the service rep said its too much work to check but i can do it just to be safe, which i think is bull****. but i dont know if this guy ever did service at an independent shop and its just not on file, any suggestions? and i do use premium |

well i want to start off by saying thank you for your suggestions and i will go down the list and hopefully that leads to some more great advice....

Also if you are sitting in really bad stop in go traffic for long periods I can see you getting low MPG stats. |
How long does the battery need to be disconnected on the 460 to reset the ECU?
Some cars are just minutes, others are hours. |
Please read the post before yours. :)
