Default My Service History

Just picked up my 2004 LS430 last week with 110,000 miles. According to the service records available from Lexus the following major items were replaced:
  • Broken cupholder - 22639 miles
  • Replaced inoperable backup camera - 40531 miles
  • Transmission replaced with remanufactured unit. Previous owner complained of DSC and TRAC lights are on and the vehicle is sluggish - 42233 miles
  • Rear driver side level sensor replaced. Symptoms: AFS light was on. Code B2416 stored in AFS system - 91614 miles
While inspecting the car before I purchased it I noticed the following issues:
  • Low tire pressure indicator on dash. Seller said that front tire needed new sensor. Pulled out my smart phone, googled problem, found this site and fixed problem using reset button under dash.
  • Telescopic feature inoperable.
  • Distortion from drivers front speaker.
  • Excessive wind noise coming from windshield at highway speeds.
  • Trunk struts weak.
  • Very slight steering drift to the right.
  • Buzz or vibration coming from subwoofer during loud and heavy bass intensive songs.
  • Drivers door lock inoperable except with key.
The car was exceptionally clean for one that lives in the rust belt and I feel that I got a smokin deal on it so I don't feel bad at all with the minor issues that it came with. I've been wrenching on all of my cars and bikes for almost 40 years and am in the process of getting all of these issues resolved. I get a big smile every time I get behind the wheel of this car...

I bought my 1st and only Lexus about 16 months ago, took delivery on (literally Christmas Eve of '16) a used 2006 LS-430, base model with NAV, and chrome 18" 5spoke wheels. Car had 37,800 miles (yes, 37K) when we took delivery. Low mileage cars are still going on market, but you have to be ready to buy when you find them. At any rate, we have put 12K miles on it, and is 200 miles shy of 50K. To date, the only non-routene maintenance item I have had addressed is replacing a fuse. One fuse. Other than that:
>new tires
>oil change (synthetic)
>replaced battery
I do not have much experience driving any luxury cars whatsoever. I've never driven a Mercedes, Audi, or BMW, so any comparison(s) I might draw would be too biased to be useful. However, without doubt, this is the most luxurious vehicle I have driven, owned, operated or ridden in. I absolutly would buy it again, all day long and twice on Sunday. Not a big fan of having to use premium gas, but over the course of a year, it really is not that expensive

Chuck, regardless of what Lexus recommends, you DO NOT have to use Premium gas in your LS. I have done extensive research on this topic, talke "Off the Record" with Lexus Maintenance Diagnostic Technicians, and many others. You can use Regular fuel all day long for as long as you wish with no harmful results. I've owned several Lexus LS vehicles, and I have NEVER used Premium as a result of the FACTUAL information I have gotten from PROFESSIONAL people knowledable about the subject.

I used regular gas in my 1998 Nissan Maxima for more than 20 years, no harmful effects. The only thing is it never achieved the 190 HP and 205 ft. lbs. of torque, that it was rated at, in the brochure.

btw I have always used 93 (it's what we have in the northeast) in the LS430, except 2X, when I knew it had been filled with 93, so I blended it down to 91, by using approx 7 gal of 87 octane. This was when I couldn't get to a warehouse club for premium (or the bad neighborhood where Citgo is located).

There are some cars that require over 87 octane, in which one cannot use regular, so if you have one of these vehicles, it would be advisable to use higher than 87 (maybe with leasing you don't have to obviously tons of people might not). The LS430 does not require premium, but it is recommended. As was with the Maxima.

Of course mathematically, having introduced 87 into my LS430 tank, it can never be 93.000 octane, as there will always be something < 93, since I have never drained the tank or run it out. But then again, only 91 is recommended. What I am describing is similar to the tranny drain/fill. There will always be some amount of original left behind.

Using regular fuel in an LS, as with most cars, will be suppressed by timing, VVTi, knock sensors etc. so you wont be harming your engine. I'm sure most everyone here will agree we don't drive an LS with the intention of dumbing it down. Granted it's not a sports car but a 10.5:1 compression ratio should be taken seriously. If you are so concerned about the additional .20 cents per gallon you might be happier in a Corolla...?

True on the minute difference in price overall. less than $5 a fill up. I still groan when it happens.... basically because i'm a cheap bastard, not poor, just hate spending money (which is why i've fixed everything on my lexus myself, minus the timing belt when I bought it because I didn't have anywhere to actually do it at that time. But not to get too far off of subject when I think about the it $5 isn't much and i've done it so much now I don't even think twice about it.

It won't really harm the engine because the ECU will retard the timing. But that will effect engine performance no doubt about it. You could drive it like that forever if you wanted to but i'd wager you would get more deposits built up from using a lower grade gas (same as any car) so there is that to think about, unless you are running fuel system cleaner aswell which would eat into the $5 savings from the cheaper gas anyway.

Problem here is that the price differential between Premium and Regular grades is 80 cents in our neck of the woods. That makes it a $16 difference for the 20 gallons that I typically fill-up with. I've probably run regular about 75% of the time since I've had the car (17 months) which has translated into about a $560 savings. I have no issue with the way the car runs. The 3UZ-FE is such a strong performer I hardly have to get into the gas to make it go.

If you're running Tier-1 regular gas I don't understand why you would have any more issues with deposits forming versus running with the premium gas from the same station.

In the end, you can spend your money in whatever fashion you like...

Couldn't agree more. There is a hefty difference between regular and Premium here in the great state of Wisconsin, and with me spending 110-120/week on gas, the difference adds up. That being said, I have switched over to mid grade for the last few months. Used to run regular and never could tell the difference.
