#1 of 28 Lexus LS Owners: MPG-Real World Numbers by KarenS HOST Jun 02, 2005 (11:03 am)
This topic is for Lexus LS owners to share and compare their actual MPG.   "Real World" Fuel Economy vs. EPA Estimates

#3 of 28 2005 LS 430 MPG by rgsw Jun 08, 2005 (9:03 pm)
Just drove 1000 miles last week. I got 29 MPG (maybe a slight tail wind) from Albuquerque to Denver. On the way back (with 40 mile per hour head wind) only 25 MPG. All driving was at 75 or 65 MPH. Very pleased with MPG. Replies to this message: todd2004 (Jun 10, 2005 1:39 pm) famwald (Jun 14, 2005 5:20 am) jerry5506 (Aug 16, 2005 7:23 pm)

Replying to: rgsw (Jun 08, 2005 9:03 pm) I just completed a 390 mile round trip from Indianapolis to Columbus and back on I 70 at 26.9mpg with an average speed of 74 mph on my 2003 LS430. The mpg was calculated on similiar filled tanks of Shell premium. Winds were out of the west between 10--15 kts both ways.The car computer said the mileage was 27.1 mpg. Great car !! I have 29,900 miles on it and I will be putting Michelin MXV 4 tires on it next week.I have to replace the OEM Dunlops due to poor wear. I am really looking forward to driving it with the Michelin tires! Replies to this message: famwald (Jun 14, 2005 5:20 am) jerry5506 (Aug 16, 2005 7:23 pm)

Replying to: todd2004 (Jun 10, 2005 1:39 pm) Re: your tires --- I had Michelin MXV-4 tires on my last two Volvos and loved them. When these factory Dunlops to wear out I'll be putting the Michelins on..

My wife uses it for commute with an average of 20 mph for stop and go traffic. When I drived it during weekends, I got average 25 mph mostly on freeway with rolling hills.

I would get about 19.5 in combined driving. About 24 going 75-80mpg. I was pretty impressed actually. These numbers are from the trip computer. I didn't calculate myself. I recently switched to an 2006 M35 AWD. It only gets about 16.5 using a V6 so the LS looks pretty impressive!

Replying to: todd2004 (Jun 10, 2005 1:39 pm) Just wonder if Michelin Tires are better than Toyo Tires. I have Dunlop tires on my 2004 LS and have approx 25,000 miles on it and seem to have plenty of rubber on them so far. I put ToyoTires on my 97 LS but traded it off soon after, so don't know how they lasted. Jerry5506
#9 of 28 2003 LS 430 Mileage by rce15398 Aug 26, 2005 (2:46 pm)
We just returned from a 4,800 mile trip from California to the Midwest and back. We averaged 27.2 mpg overall. Outstanding for a vehicle covering territory at 75 mph, in serenity and comfort.
#10 of 28 2005 LS mpg by famwald Aug 28, 2005 (10:54 am)
With the cost of gasoline rising, yesterday I decided to see how the mpg would be going 65 on the interstate instead of the posted 70 mph limit. I cleared the numbers on the display and strictly on the interstate got 30 mpg. That is with no stop/start driving and no major hills.
