Sorry for late reply.
OK so, every morning when I start the engine, it revs up to 1800rpm. It stays there for 2 minutes, after that temperature gauge raises a littlebit, then rpm will decrease to 1500rpm. After another 1 minute, it jumps to 1200 and slowly to 700 - that is when the engine is warmed up. Yes, it was always like that. I have searched a few forums, where people claimed that it is somehow ok for those cars. Till this petrol Lexus, I always had diesel cars, which always started at approx. 800rpm. Oil change by Lexus is 12000km, so maybe it is ok. Afterall this car runs like a charm. So thank you for your reply.
