This car does sit in the garage without being driven with a full tank of premium but I was told that the gas now days can go bad and cause problems with the engine if not driven several months at a time. Hopefully someone will be able to unravel this. Thank you!
Thank you everyone for the responses. I have located gas stations that don't use Ethanol and I will do that from now on. If I didn't like this vehicle so much, I would have bought a new model... This is the longest I've ever owned a car and I've had several Lexus models. Maybe it's just my age...
Thanks for all the input. It was very much appreciated!
