I'm on my 3rd Lexus, 2nd hybrid. I live 6 months in Florida and six months in Tennessee. I have learned a few things about Lexus over the 20 years. First, the mileage figures for Lexus always are overrated. I drive a 2019 450h and love it. I just turned over 50,000 miles. Two previous SUVs put 300,000 and 200,000 miles on. Two things I learned. When possible, drive in the eco mode. Second, if you can find it, use ethanol free gas. I regularly find it at Waawaa, Buckies, and some other chains. It is even at Shell now. It is more expensive, but I average 27 mpg, sometimes 28. I am a defensive driver, but cruise along the interstate at 77 mph.
