My lexus rx400h does not require premium. If you use regular you might get 1/2 to a mile per gallon less . You would not notice any difference in performance or hurt your engine.I heard that you can have your timing retard, but I am not sure that it makes any difference. Did you notice that the gas stations have quietly conspired and raised the price of premium by 40 cents a gallon? I did not in the begining.. They always challenge your intelligence and observation capacity.

The owners manual for the 2016 RX450h states premium gas should be use. The manual for the 2016 RX350 states regular gas should be used. Both models have the same engine. I've been driving my 2016 RX450h for nearly a year, using regular gas. It runs great! I've experienced no problems at all with performance or gas mileage. I see no reason to pay 40 cents a gallon more for premium gas.
