Dumb question, but I gotta ask...mpg and range

On a side note, you should avoid running the tank dry to find out how many miles you can get out of a tank of gas. The LS430 has a submersion-type fuel pump, which is cooled by the fuel surrounding it. Without this cooling medium (i.e. low tank level), the fuel pump can get overheated, especially in the summer heat. The LS430 fuel pump has an overheat protection circuit that will shut off the pump and your car will stall - a dangerous condition if you're in the middle of traffic. Repeated overheating can cause permanent damage to the fuel pump.

When I first start off cold in the morning all of my tires are now set at 36 PSI. But when I drive, the numbers are not even. For example the front driver might go up to 38, while the passenger rear can go up to 39 or 40. Will one or 2 PSI differences be an issue?

I am new and looking for a 2019 IS 300 F-Sport, but have not been able to find any inventory with the Mark Levinson Premium Audio Package. Nearly all car listings just say "Navigation Package" as an option. Does anyone know what's going on? I've come across some discussion online with people saying Mark Levinson is useless/horrible and what not, but I can't imagine why dealerships would order without it.

The last two trips of mine of greater than 200 highway miles (55- 70 mph speeds) both came at exactly the same mileage = 27.5 mpg. I would agree with others that say 600 on a tank is possible in theory.
I just cleaned my evaporative switching valve (VSV) per a recent thread. My first impression is that increased fuel economy. I was getting a steady state of about 35 + mpg on the way home at around 45 mph, more than what I used to see on the same route.

You are absolutely correct about the intake the stock ls430 intake is super efficient. The ppe headers give you 20 hp & 20 tq dyno proven and the exhaust maybe 10-20hp and 15-25 tq i would do dyno runs with the exhaust and stuff but it cost me $750 for 3 pulls with tuning and honestly no body on here gives a **** about making the car faster and just tells me that toyota did a better job than i ever will so yah lol.
My personal car is an 06 with an ls1 swap with a t56 its a completely different animal then the standered ls, i am looking for at a ats lsd and a custom ladder brace to reduce the body roll on this behemoth during cornering haha.
But anyways i am also wondering about the car ride height and chassis stiffness effecting gas mileage...sorry for thread jacking ime an a-hole.

Well to partake a bit on the topic, i've only driven mine once in highway, at the perfect setting the computer showed up to 32mpg, flat road, 25C, going 110-120KPH, it is possible in theory but no highway or interstate for americans is that perfect for a long enough stretch of road, 24-28mpg is more probable and realistic. Which is still awesome not only for a huge car but a normal commuter, it's halfway there to a CT200H and faster while we are at it! My CT200H obliterated MPG going more than 100.

I just did something never before in my driving career. I went 458 miles on the same tank, and the car took 17 gals upon filling up, implying there were 5 left and I could have gone well over another 125 miles. Seems like it's something out of a VW commercial where I think the diesels routinely went over 700 miles on a tank. I really have never gone over 400 in my lifetime on any tank. That's just under 27 mpg above. The avg mph was 51, so there was clearly some non-highway driving as the highway portion was closer to 70.
And no not 600, and octane does not yield better or worse mpgs, it simply isn't what octane measures (predetonation). I use 93 premium, which is not available in CA.
