How often to tune up? 5000 or 7000?

I have a 09RX350. I use Mobil 1 5W30, a synthetic oil. Dealer tells me that, notwithstanding the various motor / oil charts or matrices that appeared on this forum, I MUST use 5W30 oil as specified in the manual, and I MUST change oil every 5,000 miles (if I want to be sure of not voiding the warranty). The only conclusion I can reach is that the quality of Lexus engineering and motor construction is such that it requires a lot more frequent oil changes than other brands, and that this has got to be because it is taxes the oil more.

BTW, European manual for Lexus RX service intervals (actually, it mentions all Lexuses) has much longer oil change interval, as I can recall it is 15,000km. In Europe all cars have longer oil change intervals (don't think their oils are any different from North American).
To me it's kind of rip off of owners in North America.

5W-30 Full Synthetic Oil every 5K to 6K miles for me. Also drop a can of seafoam about the same time.

It's difficult to do otherwise than recommended by the dealer if you want to be able to claim under warranty in the event of failure. It would be nice if Lexus would issue a notice stating that full synthetic oil could be changed every 7500/10000 or whatever miles, retroactive to previous models. But they don't.
Overall, the RX350 is/has been a car well-suited to my needs and overall I believe Lexus engineering is exactly as good as Toyota, which is certainly 'world-class'. However, the problems they had with earlier engines/transmissions (sludge; rear engine seal; failing transmissions) and their (probably consequent) 'need' for frequent oil change compared to other manufacturers does, in my view, indicates their own trust in the toughness of their engines is less than total. Also, it is 'easy' additional insurance for them that they do not pay for and which feeds the dealers.
So I do my 5K mile oil change, preferring full synthetic because I believe it is best, and I deplore the waste in both oil and filter....

I use Mobil 1 and get oil changes done at Toyota every 7500miles. I am out of warranty (bought used) @ 105k miles. You can reset the Maint Reqd light yourself (simple 5 second procedure)

I am not sure what you mean by tuneup. The Lexus maintenance service manual requires an oil and filter change, air conditioning filter change, tire rotation and multi-point inspection every 5K. Fuel injectors, intake cleaning, engine air filter, brake fluid change is done every 30K. Coolant is changed at 100K. Spark plugs are changed at 120K. The transmission fluid (WS) is lifetime on the RX350.
Thanks.
