Hi so i know that lexus says they recommend doing it first time at 150k and then every 50k after that.
Has anyone waited for that or do people get it done before that ? like here is the thing for me 50k would be like be every 6-7 months i know some people would not drive 50k in 10 years.
so with driving city and highway mix of like 80k a year is waiting till 150k good for the first time and if so why cant we go that long each time ?

The coolant is designed to last 7 years not sure why the interval is shortened after a certain mileage. Maybe Lexus thinks the metals are going to break down much faster?

Follow the maintenance schedule, you'll be alright.... No need to question everything.
