2008 rx 350 oil change issue
I just did my first oil change to my 08 rx 350. There is no leaking under the filter or boot, but I found there is something leaking close to the right passenger tire. So I put a white paper under the leaking spot during the night and found some yellow oil-like stuff next morning. I guess it is engine oil. I only put 6 qt in the engine, but when I check the oil level, it seems above the max point. So it seems it is leaking because I put too much oil into it. I am not sure whether it is the case. Please advise what I should do next. Thanks!

Seems like a strange issue. Where is it leaking from exactly? With the oil filter change, it should take 6.4 quarts. However, some have noted that theirs takes more like 5.4, rather than the 6.4.
I would wipe the leaking spot clean, and drive the car for a little bit, and then check the oil level and the leaking area again. If the oil level drops and you need to add more, go ahead and add until 6.4 quarts as needed, drive the car a little bit, and then check the dipstick and the leaking area again. If you add 6.4, and you find that it is still leaking, and you have to add significantly more than 6.4 quarts total, then I would start worrying about it. However, it's really hard to say what exactly is going on without the car in front of me, or knowing where it is leaking from. Pictures of the leaking area would help identify what is leaking if you don't know what part is leaking.

Did some more investigating on this and it does look like it most likely is a power steering rack leak. Check this out:
http://autorepair.about.com/od/gloss...m#step-heading
It is an article about identifying fluid leaks from cars and this is how it describes power steering fluid: "Power steering fluid is a slightly yellowish liquid that is of medium thickness, kind of like cheap waffle syrup compared with water. It soaks into concrete quickly. It has very little smell but a keen nose will detect a dull, mechanical scent. It is a hydraulic fluid."

There was a disturbance in the Club Lexus force crying out for correction. Now, excuse me while I disappear and go back to my online vacation.

Sorry, gundy... you did not do enough investigating. If you had bothered to open the Lexus RX Owner's Manual you would see that they do not use a traditional power steering fluid. Rather, it uses a DEXRON II/III ATF which is red. Anyone using a traditional power steering fluid in an RX is in for a world of hurt. This is nothing new and has been discussed at length and many times here at Club Lexus and 2nd Generation RX.

mikezy--on that note, check out the service/maintenance history for past issues. If you can get one from a Lexus dealer, it will be MUCH MORE detailed than anything else you can get on-line (e.g., CARFAX).

I agree with RX330inFL. The OEM power steering fluid is Toyota Dex 3, which is in fact red. However, the stuff that you get from an auto parts store is going to be yellow. I wouldn't run anything but Toyota Dex 3 in it, seeing as how many R&P problems people are having with this car.
