Hey everyone I'm new to the forum so forgive me if this topic has already been covered, I bought a is250 f sport on 75,000ks and I have had it for a year, recently I noticed a pop up on my screen saying engine oil contact this dealer for maintenance, now iv only done 7,000 ks in the last year and when I go to setup>vehicle >maintenance>engine oil on the screen it says distance: 15,000km remaining: 8123km, very confused, I know the next service is the major 90,000km but I havnt done nowhere near that, should I get the car serviced anyway cause it's been a year or should I just get the engine oil renewed even though it says remaining 8123km, I have been quoted by Lexus of chatswood service department $970 for the 90,000km major service, if this price is too much if someone could advice me to a another service department would be much appreciated, thanks. P.S purchased the car from Lexus of Brighton in Melbourne, living in Sydney.
