Are you on Oahu? I think you found the perfect spot for the best mpg I’ve ever heard! If you are on Oahu, I can see how you are getting that mileage. I think my issue here in TX is we drive much faster because it’s wide open & we have wind that is often a negativen factor.
Yes, I am on Oahu, in Honolulu. Our freeway speed limits are 45/50 so I’m usually doing 55-60on the freeway (typical following speed). Also, My trips are typically really short, under 6 miles.

I picked up my(new to me) 2013 RX 450h last week, I am still new to the hybrid tech but looks like I'm getting around 27.7 mpg. I will need to learn all the tricks of the trade. I do love this car though! Tim

I don’t know why there is a difference in mileage between the Lexus & Toyota. I think you are getting pretty good fuel mileage, compared to me. When TX got that artic blast & the daytime temps were around 10 - 20 degrees, my fuel mileage dropped to 20 mpg. It’s rare that I ever get better than 26 mpg with any kind of gas (tried them all & no difference). A typical average is between 22 - 24 mpg. It’s relatively flat here, with some slight rolling hills & 1500 ft of elevation. Our speed limits are mostly 70 & 75 mph & some parts of I-10 are 80 mph.
Yet, here you go. I also have pic on my cell of 46.7 mpg average after 25 mile trip from Federal Way to downtown Seattle. I have no idea how, but it did.

Talking about disconnecting the alternator, there doesn't seem to be one in the Toyota hybrids. So it makes me wonder - where does the ignition get its power source to operate the ignition coils when the ICE is running? I am presuming the transaxle which generates power to recharge the traction battery and also drive the electric motor(s) is also the source of providing 12 volt charging power to replenish the 12 volt battery located under the cargo bay floor.

I am pleased to say that I just cracked 30 mpg highway! First time in 18,000 miles! I made a 160 mile round trip in the wind. On the way, I had a 30 mph slightly cross head wind & coming home, I had a 40 mph slightly cross tail wind.
Has anyone noticed if the brand of gas matters? I don’t have too many Shell stations, but I filled up with Shell 87. I had 91 already in the tank. I can’t seem to get a consistent reading for whatever reason. One time I get 22 mpg, another I get 24 mpg & once in a while I get 26 mpg.

I am still waiting to top 28 or 29 MPG on the highway. Did you get your 30 MPG while running in the Sport mode? If so, WOW!
As far as types/brands of gasoline quality, yes, it does make a difference in mileage. There are different additives in some brands. I used to get my gas at Fred Meyer (discount with my rewards card), but found that my mileage was suffering. I've noticed better mileage with Conoco and Exxon. (Maybe I will have to try Shell)
Not sure that running 91 quality in my RX is worth it for the extra mileage since it costs more. I do know that most Conoco premium gas doesn't contain ethanol, which would get you better gas mileage, but the RX isn't meant to run on premium. Thoughts??

New (2018) RX450h F-Sport Gas Mileage
Hi everyone!
I'm a proud new Lexus owner with a Maxed out (Except panoramic roof, but with the moon roof!) AWD RX450h F-Sport. I just took my car in for the first oil change (received the car last month to the day. I'm getting anywhere from 28-33 MPG (I filled up 2 times already about at not even using 1/4 tank, just to check the mileage. Two weekends ago, I took the car to the mountains, stayed the night, and came home hitting a butt ton of traffic on the way. each way was less than 100 miles but on that trip, I got 41 miles to the gallon! I haven't been on a long road trip yet but will be at the end of May to get a more accurate MPG. Here in town, going to work every day, I'm right at 29.4 MPG and I do not treat the car like a baby. maybe I should?
Anywho, I just replaced the original wheels and tires with a 255/50/20 Michelin Premier LTX tire from the stock Dunlop 235/55/20. the people who swapped out my tires recommended 270Kpa (about 39 PSI) due to the size of my car/weight. My question is, does anyone have the same tire and config that I have now, and what PSI are you running, with how is your RX handling it?

My dealer says to keep it between 33-36 PSI, and I have the F Sport model as well. It was at 35 when delivered, and mine had the premier LTX tires from the factory (not sure about the exact sizes though)

The RX 450h has a sticker by the gas cap stating it should have premium fuel. I’m not sure about the fuel requirements for the RX 350. EVERY brand here has ethanol. We only have a few She’ll stations that are at least $.10 a gallon higher than everyone else. There are a few Chevron stations & zero Conaco, Exxon or Mobile stations.
I've read a couple of blogs where people are using premium now and then, but mostly use regular. I'm probably going to do some switching back and forth also, especially with Conoco gas, which has no ethanol. I have noticed, though, that our Conoco stations are becoming few and far between in my area.

Well, well! I checked inside my fuel door and it says premium grade fuel! My Lexus dealer told me the 2017 RX 450h used regular and I believed him. I didn't doubt him since my 2013 ES300h ran on regular.

One way to settle this is switch the cars for a month with your dad and see. 80% of MPG depend on commute and the rest is on driver.
For my commute on Rx350 I was getting 16MPG with Rx450 I am getting 24 for same commute. I live in Orange county and last weekend went to San Diego and a few days later went to LA with commute change my MPG went up to 29.
