what mufflers and define non ethanol gas

Biggotis06

Magnaflow Axel-Back Exhaust, and you can probably define the non-ethanol gas better than I can j! I think the oil is the biggest factor. It always helped the mpg in my other vehicles

In the US, most gas contains 10% ethanol. Supposedly to reduce emissions. But in reality, it contains less energy per unit mass than gasoline so the redution in emissions per mile is very small. It's mostly a political issue with corn farmers getting huge subsidies from the government to produce corn for food and ethanol production, but you can guess where the majority of it goes................

How many miles did you drive on your trip odometer and how many gallons of gas did you put in when you filled up? The true measure of mileage. I just got 29 MPG, 549.9 on trip odometer when the fuel light, put a little over 19 gallons of gas in when I filled up. Probably could have driven another 20-30 miles with the light on.

Here in the North Land we too have non-oxydenated(Ethanol free) premium 91 octane. Currently running at about $3.44/gal.
I get this same mileage pretty consistently, running 57 miles each way to work and back.
Only a couple of small towns and 2-3 stop lights.
Usually running at 60-65 mph.

I just paid $4.01 a gallon for the wonderful "California Summer Blend" 91 octane at Chevron this morning!

i wonder if gas in Ukraine has ethanol..... hmmm

jdanielca - I am really glad to have you and other non-U.S. members on this board. See if you can find out if your fuel has ethanol. Probably it doesn't. Because in reality, it makes no financial sense, and probably increases pollution (due to the energy required to produce it) to add it to gasoline. It was politically driven in the U.S. which is where the nonsense comes into play. The only thing the U.S. gobment does well is the military … and that because the politicians mostly keep their noses out of it. Oh well, a different topic. What I really wanted to add was...

I drove my son's G35 over the weekend on a 280 mile road trip. I had to use the A/C, as it was 90°+ outside. With smooth driving, only 5 mph above the speed limits, steady cruising, trying to be conservative, it achieved about 26 mpg. It is a helluva nice driving vehicle. Perfect for a youth, and (relatively) inexpensive to purchase used (2005 model). But Toyota / Lexus really made us something special for the LS. 385 hp, really nice V8 torque and sound*, up to 30 mpg, BIG, comfortable, reliable, inexpensive to maintain. What's not to love? Just wish they would offer a V8 for the 5LS. Otherwise, my next vehicle will be one of you guy's 2016 or 2017 LS 460's!

I agree that the LS 460, like the old Northstar GM's, put up impressive MPG on the highway. I do think that the weather conditions matter. If you have a wind at your back on the highway, you will get into the 30's. If you are driving into one, you might see a 10-15% drop in MPG. So oil, tires, gas, may have an effect, but I notice much more variation depending on the wind direction at the time.

It probably still has lead

Second this. Gotta calculate by hand to be sure. I track every fuel up and calculated MPG on fuelly.com. I know our LS 460's MPG readout is optimistic by 0.8 - 1.5 MPG. I won't really believe I'm achieving 30 MPG unless the computer reports at least 31.5 MPG. I am still impressed by the highway fuel economy of the big V8 though.

I drive 38 miles each way to work. I finally figured out that if I use cruise control, I get 26 mpg. If I don't use cruise, I get 31 mpg. I didn't believe it until I tried it over two weeks. Try it. BTW, all highway miles.
