I am gonig to get IS-F , but I have couple of question about IS-F
1: In manual mode" M mode" Example:when i put in sixth gear, and press the gas pedal fully, does the car downshift? Or just hold in sixth gear.Just like traditional manual tranmission?
2: can i do engine oil change by myself? I heard about new Lexus need dealer service
thank you

To answer your question's, the IS-F will not shift Up or Down if your in Manual Mode. It is designed to work just like a traditional Standard Transmission would. This is great for people that like to run the car hard on a track and make sure the transmission does not override them and suddenly they are in the wrong grear. This allows the driver to "bounce" off the rev limiter if needed/wanted.
As far as changing the oil yourself, you can, but is not recommended.

the car will downshift automatically when in manual mode when you stop / decrease speed enough

If your not a Lexus tech, it's not recommended. It's not required because by law Lexus would be required to do all work, but again, it is recommended. Plus, you want to get to know your Service Department, and not just go there if and when you need warranty work. You'll see a dealer is willing to work with you a little more when they see you for all your service needs, not just the free-bee's !

Makes sense. I was just curious. I've done some oil changes and minor work on some of my cars in the past. I was afraid that there was something different with Lexus that would affect my warranty if I did some work myself.

You can change your oil by yourself if you want to, it's not that hard. Just be sure you have the proper filter removal tool and 10 quarts of oil and you'll be fine.

talking about oil, i read the recommended viscosity is 5W30 which is good up until 38 degrees celcius, over here in the summer it can get up to 50 degrees celcius so what do u recommend I do? is it bad to put a different viscosity? other than that, Im still breaking the engine in so im not going over 3000 revs, however i tried manual mode and i didnt notice the quick shifts, does it only work when pushing the car??

Here is the way I look at it...My time is worth more than what I pay someone else to change my oil. Let them worry about buying the necessary parts and clean up. I do enjoy working on my car, but doing dirty work to just do dirty work is just a bit of a waste for me. Look at it this way, if something goes wrong you have someone else to blame;). Besides the'll vaccuum and wash your wheels for you when you bring it in.

Technically that sounds very appealing with the free wash and vacuum but then again some owners had their car washed by the dealer and ended it up with scratches to their paint. THIS IS SOME DEALERSHIP NOT ALL!!!

you'll be fine. the car comes with an oil and tranny cooler. just keep an eye out on the oil temp gauge. it's been tested in extreme heat and high rpms and all-out. don't worry about it. the quick shifts happen only in sport + manual mode, not normal + manual.

My experience in manual mode + sport is that you have to be flogging it a bit to get a quick shift. If I'm just dawdling around with a little bit of throttle, the shifts are pretty slow, actually.

That's correct. The absolute fastest shifts will be when shifting at WOT. There's no point in the TCU/ECU making the tranny do fast shifts if you're not flogging it. Otherwise the shifts will be harsh when it's not needed.
