What kind of fuel should I use in my Lexus ES350?

I just gotta brand new Lexus Es 350. Im right now running on the dealer's 91 octane fuel, haven't driven it around that much. Should I get plus fuel or premium fuel. The dealer told me the car will run fine on all three, and won't affect the engine, just a little better performace with lus and premium, what should I get.

    Well, it will run on any 3, but your probably paying a lot more for nothing just buy getting premium at 20 cents extra a gallon. Check the manual your car came with, it should say somewhere which one is recommended for your car. Most cars however just recommend the 89.

    Take it to the dealer and tell them. I do not even bother troubleshooting a car under warranty and not even some with a price tag like that. That is not normal and I never seen some like that on any new vehicle, domestics or imports. Did you let someone borrow the car? It could happen if someone was trying to drift on your car and pulling the Parking Brake to make it slide, ride the brakes or racing around doing some hard braking. Good luck ! :-)

    The LS430 is premium only and I think other "Lexi" are the same.
