Lexus GS 2006-11 :: Gas Mileage Declined
Nov 22, 2013
So, I'm down a good 6-7 mpg recently and I can't figure out why. When I put the k&n intake on , I got about a 1.5mpg boost in highway driving. Added the tanabe exhaust with no change. My only update would be f sport sways and 20" wheels. I started noticing the decline before I added the wheels, so it can't be all from that and I know damn we'll sway bars won't change my mpg. The filter only has about 3000 miles since install, no where near the recommended cleaning time.

I got the EV range 13.3 miles after full charge (110V) at the first 3 weeks. From this Tuesday ( it was quite warm here), I noticed that the EV range 13.1 miles after full charge (110V). Wednesday and today was same: 13.1 miles.

I haven't owned a Lexus in a while. I had a 95 ES300 and a 90 ES250.
I just bought an 07 with 66,000 miles on it. Amazing shape. Had it checked out at dealer, no issue other than a new battery.
I am on my second tank of gas and average about 16.5 MPG. All of my driving is to/from work, which is only about 2 miles. So, a lot of start/stop, shut off, repeat.
I do make a couple 15 mile trips a week to the store, etc. I know I shouldn't be getting 30mpgs based on this, but does 16.5 seem low?

I've had my XB 5-speed for nearly a year and 10000 miles. It as been dead on reliable and fun to drive. My gas mileage has varied from 26 to 31 in mixed driving and from 32 to 35 on the highway. I use premium fuel only because I can get it without ethanol. My fuel mileage also increased a couple of mpg due to getting the power robbing ethanol out. True it is probably not enough to offset the extra expense but I like not having the stuff in my car. My only dissatisfactions has been with the transmission gear ratios. They are way to low. This torquy engine could easily do with a ratio that would drop about 500 rpm for more relaxed highway cruising.
As it is, though, my XB will go up any hill or long grade without breathing hard! Another is the instrumentation. I don't mind the center mounted set-up but speedometer and trip meter for mpg ratings are both inaccurate. My speedo reads about 2.5 mph high and the fuel mileage read out has about the same error, also on the high side. I have the stock 16" tires. The clutch has a narrow engagement band and can be difficult to be smooth on. The car is fairly quiet, is comfortable and this years hot, humid summer has shown it has one of the best air conditioners I have ever experienced in a car. I thought it might be an electric unit rather than a belt driven compressor because there is absolutely no perceived drag when the compressor kicks on.

I just had 10,000 mile service performed on my 2014 ES300H. I mentioned to the service manager that my mileage has come down to 36-38 mpg from 39-41 earlier. He advised me not to rely on the car display reading but do it manually for more accuracy. He said that many owners have found that they get better mileage than shown by the display.

This is in regards to a 2007 Accent 111k miles, about 3 weeks or so .. I had a p0420 code, and replaced the downstream o2 sensor, and the CEL went off, and gas mileage went up. Now today I got p2096 code. Seems to mirror the p0420 code. So now I am thinking the catalytic converter.
So my questions are:
There are two catalytic converters right? one would be the exhaust manifold and the other would be half way through the exhaust system after the two o2 sensors?
Which should be replaced in regards to p2096?
Could anything else be causing this code?

So in one of the owner's manuals, Lexus states that use of EV mode does NOT increase overall mileage. I was surprised by that. If this is the case why have it? I have been using EV mode after I get off the freeway and drive a couple of miles through our subdivision. I deplete the battery almost completely (2 bars) but make it into the garage. Will this damage the traction battery and should this not improve the mileage. The engine runs in the morning anyway to warm up and the battery charges up then. I am just wondering how others use the EV mode.

It's pretty cold these day where I live (about 2 weeks of -20C and lower). I know that winter can affect gas mileage but right now, I'm averaging about 13l/km (18mpg). I believe this is not normal.
I just bought the car and I noticed that the engine temp looks low to me (see pic attached). Is it supposed to run this cool? I also went to the garage and he checked with a obd2 scanner and nothing was wrong. Could a stuck thermostat be the cause of my poor gas mileage?

I have a 2008 Elantra with 50,000 miles. I know I was overdue on the tranny fluid change and the car was getting bad gas mileage and skipping gears. I brought it in and had the tranny flushed and refilled and now its running good. I thought it would be good to get a price on spark plugs because the book said replace at 60,000. I called the dealer and he basically told me he has not sold many of the plugs and they should last 100,000.
I seem to be getting conflicting info on what should and should not be done at the maintenance books written schedule. I looked for a price on Fuel Filter air filter which is in the maintenance to replace but again conflicting info stating that should not be changed unless there is a problem. Anyway, what should and should not be replaced at specified intervals? I know the tranny fluid change should have been done at 30,000 because it was very dirty and causing issues for me.

I had made a trip down to Branson Missouri for Christmas, which is about 1000+ miles round trip, and the milage seemed to be slightly lower than normal on the computer, about 23 mpg. I went to Iowa after that for Christmas and filled up my tank once when I was there, I was sure to get 91 octane gas. Then after doing a lot of in town driving it went all the way down to about 11 mpg. It jumped back up to 17.9 as I was driving back up to the Twin Cities and hasn't moved after doing some in town driving since then.
The tank seemed to match the computer as far as how fast it dropped, but I'm curious if there's anything I should be looking for. I have a K and N filter in there, and it's only been used 10,000 miles or so, but I cleaned it anyways, since there were some bugs and small leaves in it (there was also a large black spot on it that didn't look like dust or dirt, more like something oily, if that means anything). I'm planning on filling it up a couple more times and seeing what happens before I start going to my mechanic, but I'm switching jobs and will be driving it for work, so I'd like my vehicle to be running well.

Checked the MPG Since Last Fillup numbers against computing the actual miles driven and fuel used manually? I find the (2011 460) numbers to be consistently 2 mpg or more higher than actuality. To be as accurate as I could I used the same pump at each filling, letting it stop automatically when full. I now wonder at the accuracy of the "total mpg"--which shows 14.1 for 15,000 miles. I drove 5000 of those, and never got more than 12.5 mpg (by the Lexus meter.)

With the colder weather in the NE, I am experiencing lower mpg with the ES 300h. We have had several cold days here, and my mpg seems to be going down. My driving habits have not changed.

She was driving and she turned onto another road this morning and the Prius started making a popping noise which lasted about 30 seconds. She normally averages about 42/43 mpg but it is down to 37 mpg. She said she has noticed since yesterday the Prius did not drive the same (I am assuming she means the power). The Prius is a 2006 with about 105,000 miles on it. Nothing has ever been done to it since we purchased it new in 2006 except oil and tires.

I have a 2009 Hyundai Elantra SE, and up until very recently I've had no issues with it, and am very happy with this car. About 2 weeks ago the malfunction indicator light came on. I checked the manual and it said to contact the dealer ASAP to have it checked out, but the car will still run. I've been terribly busy, and this is the first chance I've had to bring it in, so that's the plan for tomorrow. What this could mean, and will any necessary repairs be covered until the 100,000 mile warranty? If there is a repair needed that isn't covered, I definitely don't want to take it to the dealer!
Also, a few days after this light appeared, my gas mileage has been horrible, apparently. I say apparently because the digital mileage range now tops out at 255 when my tank is full; it used to be 336. It costs the same to fill it, and takes the same amount of gas, about 12 gallons. The gauge goes up to above the Full line, but I seem to go through gas so much quicker. Today for example, a trip that normally would cost me maybe $10 in gas, at the most, cost me almost $20. I haven't noticed any leaks, so perhaps this is related to the indicator light?

I bought a used 2008 Sonata GLS with 65K miles 2 years ago. It's been a great car so far. For the first 25K miles that I drove it, it had good pickup and got ~30 MPG for my highway driving. In the last ~5K miles, the fuel mileage has dropped to 25MPG highway and it has some hesitation when accelerating, especially on lower RPM's. I changed the spark plugs with NGK Iridium, but it is still having the issue. What to check?
Some possibilities: ignition coils, sensors, timing belt, etc?

I enter a new address into my navigation probably 10 times a week and have noticed an unusual issue, The mileage to the destination always changes when I start to move. I do not see a pattern but it always estimates the trip and then adds 5 to 9 miles or so when I start moving. I understand if I am in a driveway or in a shopping center it must recalibrate but this is not the case. I am choosing a direct route so the other routing options are not a factor. I miss my Joy Stick to move around on my MDX and the touch screen to move around on Lexus is annoying and it sucks to stop the truck to enter an address.
