  1. Amsoil lists 75W-90 for all temps for your car. That's what I'd use as a preferred viscosity. That should cover the manual's specified viscosity without any issues.
  2. Also, if your dead battery is less than 3 years old you may be able to get credit for any remaining months left on the warranty. Check the date sticker on the battery. Costco and Walmart are my favorite battery vendors, in that order. When I pick the battery, myself I get the newest battery based upon the date code. If you are planning to change it, yourself, you will need to relearn window operation. See your owner's manual for details. If a dealership changes the battery, they should do this for you.
  3. I recommend 3M VHB tape. It has affixed many things to many types of surfaces and has never failed me. It is foam with adhesive on both sides and comes in various thicknesses and widths. Make sure the surface to which the tape is to adhere is clean. Alcohol usually cleans non-metallic surfaces well. 3m vhb tape | McMaster-Carr
  4. Have you checked out ? They are amazingly helpful when it comes to aftermarket audio and audio/visual equipment. And their installation instructions are excellent.
  5. Very true. I wonder if your dealership has had any similar complaints? Sometimes an auto upholstery shop can add padding. We have a couple of those shops in this area.
  6. I would first check the battery cable connectors on the battery posts. Are they both tight? You should not be able to rotate either by hand. Did you have the battery load-tested? Simply measuring the battery voltage will not identify if the battery is load-capable.
  7. Seats are designed for the "majority" of people. Unfortunately, not everyone will be comfortable in every seat. When I rented a $230,000 McLaren 570S Spider, it took only 20 minutes on the highway for the driver's seat to cause a very aggravating lower back pain. I guess I didn't fit the design very well.
  8. The cold starting issue could possibly be caused by a failing fuel pump, fuel injector, or temperature sensor. Heat increases resistance in electrical circuits, and it is possible that once the fuel pump has been running for a while, high resistance causes it to slow or stop. The same high resistance can affect ignition components. Make sure all of your electrical connections are clean and secured.
  9. I interpret this as meaning you can use 87 or higher octane but I've also seen car manuals that add " Higher octane fuel will provide higher performance." or something similar.
  10. This is regarding a different Lexus but the response to the poster's question may be relevant to your situation. Ground Wire attachment Location - ClubLexus - Lexus Forum Discussion If not, hopefully someone with the same generation of RX300 can pop the hood and see where the ground wire is attached.
  11. Such a situation happens because one or more speaker terminals are surely grounded to the metallic door. Has any work been done to the dash or a door?
  12. It does describe a failing alternator when a high enough load causes the engine to die. Did you inspect the alternator connections? When the car dies, does it start right back up? When you step on the brakes do the brake lights illuminate?
  13. I guess that after 190,000 miles something had to be worn out. I'm surprised they lasted that long. Ours have 134,000 miles on them and appear to be just fine.
