Why oil ever 5,000? Are you using standard non synthetic?
At 70,000 you havent done anything with the radiator yet?
Yes, it is a sealed transmission but the fluid should be changed every 60K miles. Our transmissions generate lots of heat and can wear out the fluid.
I do use synthetic oil (Castrol Edge 0W-20). I've always changed my oil every 5K miles and I'm used to it, been doing ever since my first Lexus back in 1996. Also it's easier to keep track when I need to change it.
Haven't done anything to the radiator yet. It's still the original radiator. As for the fluid Lexus replaced it not too long ago. There was a TSB and I brought the CT in and Lexus replaced the fluid at no charge.
I'm also glad there are no serpentine belts to change and as for the timing belt there is none. Our CT has a timing chain.
