You get better mileage in warm weather for one Summer gasoline has different contents in it too in case they changed over recently at your local stations. There's plenty of other factors that impact mileage too. But I can tell you that all else being equal it's impossible to get better mileage from lower octane fuel. There's nothing chemically inherent in lower octane that can cause that to happen. If your car is designed for 91 you will either get the same or worse with 87 if all else is equal depending on how much the ECU is having to adjust Problem is all else is virtually never equal. In the meantime you're damaging your engine though. Like I said, if you don't plan to keep the car a long time, and plan to lie to the next buyer, this won't be a problem for you, as the damage will likely take a long time to be apparent. how can 2 or 3 in octane be that much damage seems kinda weird, I am not convinced its as bad as you say. I without a shadow of a doubt am getting more mileage. The weather was the same temp so no major deviation.? I am going toput the same brand premium and see.

When I drive my wife's IS250 - her personal plate reads: SEXELXE - and I pull up next to a great big dude scrunched up in a little Mini Cooper, I don't have any problems with my manhood!! I disagree i think the car is masculine out of the box. Especially looking at the front or seen in rear view mirror. Also I have never seen a woman in one and I have been seeing alot of IS's all of the sudden all over. But a chick in an IS IS PRETTY FREAKIN HOT! sOME NICE HEELS STEPPIN OUT, sniffy sniffy MMMMM (oops sorry got carried away a minute)lol

I filled up with regular this week and I am telling you it is lasting forever what is up? I filled with Exxon Regular I think its 87 Octane. The same exact miles to work and back the same mundane cycle every week except by thursday I usually need a fill and I still have a 1/4 tank, I am really blown away, how could this be?

Good answer, thats exactly when I did hear it, in the morning backing out. The car is new with 4,000 miles and just had 5k service. TX Guys!!

100 posts. Congrats. LOL It may have something to do with bluetooth, the common facto was I was on the phone when it happens!

ok Bartkat no prob!

I noticed today that I can hear the brakes when applied. Its not a grinding but I can really hear it clearly. I usually have the radio on and never noticed. Should I be concerned?

Knight it worked! You are the man! How do you know all this stuff? It does still beep like 4 times then stops. But much better. If you can tell me how to disable the door open beeper that would be awesome. I am not a beeping kinda guy!!

This is bizarre, sometimes a CD pops out of the disc changer while driving? Has anyone had this happen?

ok, I am man enough to admit that I put regular in last fill. I notice no difference at all however the funny thing is i gained an extra mile per gallon? I was consistently getting 24.5 now 25.5 hmmmmm? Knightshade!!! give us a brilliant reply!!!! lol

Tankers pull in with regular that has had a additive dumped in the tanker and splash blended. Whose to say how much? I am smelling scam with this. These are interesting if you have time. http://www.edmunds.com/advice/fueleconomy/...93/article.html http://www.chron.com/disp/story.mpl/business/5634330.html "Manufacturers want to be able to quote high horsepower numbers," Brauer said. "If it's not run on premium, it probably won't ever hurt the car. It probably won't ever be noticed by most drivers. But they can still have their claimed horsepower for their brochures." full article: http://www.washingtonpost.com/wp-dyn/conte...0501595_pf.html

I decided to open a varying discussion on the 'what gas have you been using discussion' Topic. This is the last 2 comments at the end of the pages of that topic, i brought up what I feel is a valid point. Can I use regular gas in my IS 250? Just Kidding!!! Lets discuss the possibility that you spend the extra money on the Premium and it turns out that its Regular anyway. How can any of us even know if we are getting what we are paying for anyway. The number on the pump is a number. Does weights and measures or someone even make sure stations are doing the right thing? Stations are closing down left and right with the pricing going crazy, Exxon is getting out of the gas station business and selling all the stations. Transport companies that haul gas are also getting out of the business. This will all lead to more shady situation. I see gouging all the time, I can go 2 miles and see a .10 price difference and they really overcharge premium. In conclusion can we even trust we are getting high octane gas?

Honestly, it's not worth them risking being put out of business to make an extra $2 a tank off people anyway. nomad2009 View Member Profile Add as Friend Send Message Find Member's Topics Find Member's Posts Today, 11:16 AM Post #55 New Club Member Group: Regular Member Posts: 14 Joined: 4-June 08 Member No.: 72,753 Car Model:IS 250 2008 Location:Northern NJ Warn: (0%) Oil and gas companies are always getting busted for fraud. A huge NY company just got busted for pumping air into the line so that the electronic registers pulsers would think it was more fuel. They ripped everyone off for 17 years. 2 bucks adds up, they make small margin on selling gas. http://www.11alive.com/news/article_news.aspx?storyid=112745 http://www.thedenverchannel.com/news/6774024/detail.html http://www.nytimes.com/2007/07/20/nyregion...ml?ref=nyregion http://www.wfaa.com/sharedcontent/dws/wfaa...g.456d5532.html Just google it this was the first page, i bet 1 out 3 are cheating ya, and you car is fine on that placebo thats in you heads! i am opening new topic on this thanks knight! So i say to all the "Premium Pumpers" what if in fact as you so staunchly debate how well your Lexus operates on the High Octane you have been using Regular crap gas? With no Knock, knock knock............................

One of the many reasons I saved 3k on the factory nav and got a $300 garmin that does a bunch more stuff and doesn't cripple itself in drive :P But yes, there's 3 ways to override that- 1) Own a 2006 and never update the maps/firmware- For these folks there's a software override you can do each time you start the vehicle to remove the lockout. 2) Physically take apart the center stack and hack some wiring- this works on all years on the 2IS, but obviously has potentially unpleasant warranty ramifications. 3) There's a kit they sell in Japan that will work on the US-spec 2IS that does the same thing as #2, but it plugs into the wiring instead of you having to cut it up- you'll still have to take stuff apart though... it runs about $300 you are a wealth of knowledge knight! that sux not easier fix however I am going to try your seat belt fix today thanks again!

Is it possible to disable the inability to use the navigation while car is moving? It *BLEEP*es me off that my wife cant look up a freakin address while we are going somewhere. Its so stupid, what happened to freedom of choice. The same crap technology is on my sequoia which is the same software.

I have the 08 and I have the same problem. I have given up using it for my bluetooth phone connection. Its easier just dialing off the phone, then bluetooth picks up the call anyway I have given up on the voice commands. Its a novelty the salesman can show off. To change the temp its easier to hit climate and click down the temp arrows, by the the time she gets it right your frustrated. i havent used it since the first day or to show someone it had it. I am very disapointed in that and the mapping is not great either,my sequoia has the same mapping and it sucks.

Excellent! I will be doing this immediately. Thanks Knight!! Is it possible to shut the beeping when the door is open too?

This one is bluetooth and is installed on all sides. It is hidden too. Its radar laser and jammer. I am going to shop around 1500 is expensive especially if its bluetooth, they dont have to wire it around the car they do have to remove the dash panel . Im not sure I can do it myself I would hate to damage my car.

I have an Escort mounted on the windshield. Texas must be one of the few states in which it is illegal to have a detector, huh? I aam pretty sure NJ is illegal also. tx will LOL... Sorry. I saw the 'TX' at the end of your post and thought, "He must be from Texas!". Then, after replying, I saw your profile and realized that you are from NJ. I was rather tired yesterday, and it showed in my reply! no prob!

I have an Escort mounted on the windshield. Texas must be one of the few states in which it is illegal to have a detector, huh? I aam pretty sure NJ is illegal also. tx will Not illegal in NJ. :) Really, thats awesome! Is the jamming illegal? tx for fyi joe!

Hard to imagine a Lexus dealer endorsing this and then guaranteeing it. Or are you saying it's a manufacturer's guarantee? Its def manufacturer but Lexus will sell it and install it. they tried to close me on it when i got the car the credit manager had his list of "your an idiot if you dont get this" extra coverage, extra insurance yada yada and on that list was this radar detector.Which i sort of wished i considered it actually when i got my speeding ticket last week

The unit is called Calibre, has anyone heard of this? It sounds too good to be true, I would love to kick "the mans !Removed!" with this unit ists hidden. They guarantee if you get a ticket they will pay it?
