I purchased a used 2001 Rx300 a little over a year ago. I am almost positive that I have the engine sludge problem that is, from what I have discovered, somewhat common in this vehicle. Could someone please tell me what I actually have to present to the dealership so that I can have Lexus repair it? I have been told so many things by so many different owners, dealerships, and Lexus that I don't know what to think. I did not save oil change receipts b/c I never knew that I needed to. My service book is filled out and I do have my two most recent oil change receipts. I have maintained the vehicle properly myself, but, obviously I don't know how it was treated before me. Any info or advice would be very much appreciated!
