    I have a 2006 LS 430 and on a recent trip from KC to St. Louis I averaged 31.5 mpg on the trip over and a little over 27 mpg on the trip back. Average speed somewhere between 70 and 75 mpg. I think this is outstanding in a fairly large car with a v-8 engine. I can only attribute the difference to wind direction. Tail wind on trip over, headwind coming back.

    That is good mileage indeed. Did you have to use the mandatory 10% ethanol in the gas over your trip?
  • houdini1houdini1 Kansas City areaPosts: 5,860
    Yes, I had the 10% ethanol. I also made this same trip just before Christmas in 2008 and the results were almost identical. I had no idea this car would get that kind of mileage when I bought it. A very nice surprise.

    I see small compact cars advertising that they get 31 mpg on the hwy and just laugh. These things should be getting 60 mpg.

    The computer on my car shows a lifetime average of 24.1 mpg on the 36,000 miles on the car. What surprises me is that the lifetime mph average is only 31 !!

    In that case, wow, your mileage is indeed great for this type of car.

    I assume you used cruise control for most of the way. If you did not, you must have some great driving habits especially your right foot! :)

    Whatever you do, DO NOT buy the Dunlop Direzza tires for this car. They are so noisy, it sounds like I'm running in 2nd gear most of the time! Even the Mark Levinson has trouble drowning out the road noise....... And if anybody out there has found a good quiet tire to replace these with, I'm listening......
  • nvbankernvbanker Posts: 7,285
    Yes, mine does the same. It's one of the best kept secrets about these cars - their mileage is phenomenal!! Why would you NOT want to buy one of these cars?
  • vchengvcheng Posts: 1,284
    I took a 700 mile trip on my 2005 LS430 this past weekend. My average for the trip was 25 mpg, including 70-80 mph cruising and idling at two border crossings for 40 minutes each time.

    Struts...Does anyone know about KCB struts for my car? The Lexus dlrship will charge me 3x as much to replace my front struts. Also, Regarding tires...I currently have harmony michelins and they have been there another tire comparable or should I replace with the michelins...a quiet soft ride is very important to me...and the harmony michelins provided that ride...

    Thx for your feedback....

    Don't run anything but summer only use tires and the Bridgestone Turanza is the best of those, nice and quiet and comfortably riding.
  • wwestwwest Posts: 10,706
    Our '95 LS has over 225,000 miles with no indication of a strut problem.

    Why do you think yours need replacing...?
  • nvbankernvbanker Posts: 7,285
    Thank you - I will do that.
  • gwendolyngwendolyn Posts: 46
    My car hits really hard on the right front...the right strut doesn't have any's almost like it is stuck...if i hit a pot hole even a small small one...feels like metal to metal...feels really hard... hits really hard...
  • nvbankernvbanker Posts: 7,285
    Has it ever been replaced? If not, it's definitely due, as likely are the other three.
  • gwendolyngwendolyn Posts: 46
    OK here's the latest...I replaced the frut struts, replaced the michelin harmony tires with the same (all four)....the right side still does not feel as soft as the left side when hitting bumps/pot holes...pls advise...

    Twice now I have gotten caught in "fresh oil and loose gravel ahead" situations, which really trashed the lower plastic moldings with some tar actually up on the rear passenger door metal.

    I searched the Web for mudflaps, but couldn't find anything that would fit my model.

    Loyal readers, any ideas?

    Thanks, Pat and Karen; this is a great site and I refer to it all the time.

    I'm new to this forum, so hopefully I can jump in here and ask this question. I bought a used LS400 '95 today, with 110k miles on it. Bought it from a dealer who got it in trade-in, and there are no service records. Carfax was clean, and the car looks very well cared for an maintained. I purchased an extended warranty which covers many major issues, including, apparently, timing belt, timing cover, water pump, etc. Power train, base coverage, high tech coverage. Should I assume the timing belt was changed at 90k, given the cared-for look of car? Is there any way I can find out if timing belt has been changed? If it has been changed, does it need to be changed every 90k? I used to have a '94 Camry, which I think also had timing belt replaced at 90k? Should I just assume it hasn't been changed and do so, or should I bank on the warranty, should anything happen? Thanks.

    ... is critical on these engines, so it would not be wise to assume anything. If it breaks, then you are looking at major hassles and expense, covered by insurance or not, and in a car of that age, may lead to scrapping an otherwise fine vehicle.

    If a dealer has ever changed the T-belt, they will put a specific sticker in the engine bay stating the date and mileage at replacement. If you cannot find any such sticker, the belt can be inspected by removing a small top section of the cover by a good mechanic.

    Also, consider asking your local Lexus dealer to look up the VIN specific service history form there compter (assuming that the dealer you bought it from was not a Lexus dealer).

    I would suggest assuming that it has not been changed, and get it done for peace of mind if $600-$850 is worth it to you.

    And yes, it needs to be changed every 90k miles, which, in a car of this quality, can be done maybe 4 or 5 times till something else kills the vwhicle.
