Hello Matus,
this is my first post in the forum, so hello everybody :-)
I am a Spaniard living in Germany (since too many years already) and proud owner of a Lexus IS250 Sport since one year ago. I use my nickname everywhere, so you can find me in the German Lexus Owners Club and in several Hi-Fi Forums to find out a lot about me ;-)
Actually, in the German Lexus Owners club has been explained that there is no learning mode for the driving style, but just the on-board computer logging the exact parameters of the engine to optimize performance. I only drive my Lexus, no idea what is under the hood (but I like it, hehe), but this is contradictory information. I am confused...
Maybe this is good for the diesel, but definately not for the petrol engine, where I do not go beyond 2000rpm often when trying to drive sparingly. And I am sure the automatic gearbox works fine and tends to keep revs between 1200 and 1800. I also have reasonable mileage values.
Never use neutral gear when driving. First of all it is dangerous, and on top of this, you will actually increase consumption when doing so. Use a long gear instead. At least that is what experts at ADAC (sort of the German AA) claim (among others) and it makes sense from a technical point of view (it has been measured too, AFAIK).
I do not mean to be a smart-*****, although I know it is a strong entry I am doing here ;-) Specially because I am not an expert by any means, but rather an ignorant quoting what I think I have learnt. So be kind :-D
