This chart compares what my C's computer calculated for MPG to simple arithmetic. Seeing consistent optimistic numbers from your computer like I am?
The average error is -2.7 mpg and the STD is 0.85 mpg. So the error is fairly consistent. I also have shown the gallons purchased, but there is no correlation to mpg error.
I understand that the EPA may not consider stops at traffic lights, but when cars are stopped with their engines running, gas is still being used. I suppose this may be one of the reasons why we get worse gas mileage numbers than what they claimed to get. Or is the amount of gas being consumed extremely small and not worth adding that factor in? If you were to calculate your gas mileage with each fill-up, that is taken into consideration.
But with a Prius, or other hybrids, the gas engine is oftentimes off and not using fuel when stopped. Again, when calculating mileage with each fill-up this gas consumption is part of that calculation.
I know that you can't really calculate mpg for a car that is not in motion, but there must be a clear advantage of having a hybrid when stopped at lights, etc.
For the average mileage calculation that appears in the odometer screen, what resets it? Seems that it self-resets at 1,000 miles. Is this correct?
View 6 RepliesHow accurate is the calculation from the car's "computer" for the cruising range left?
In my experience from my previous vehicle. When my gas light would come on, I believe it generally meant that I had 2 gallons left in the tank before stranded.
I am a new 2010 prius owner and I am very interested in obtaining the max MPG in my new car I have read and seen video with regard to the pulse and glide method. My question is
1. can you shift into neutral on the glide
2. can this do any harm to the car.
How do I turn the "fuel consumption comparison" off? I want to see only the quantity and price off the gasoline I have consumed.
There isn't a "disable" feature, so I am guessing I set it to 0 mpg?
I just gonna buy a new car. How this two car compared? I have test two cars, and like ford's handling, while Prius drives like a toy. Also ford seems safer than Toyota.

During my 35 years of experience as a production line and service engineer in the aerospace industry, it was my job to determine the least expensive and easiest foolproof way to perform any production and service operation.
Many readers here have related their experience with the oil filter housing and their difficulty with its removal and reinstallation with the need of a torque wrench to correctly tighten it. Most all technical tightening of screw systems have gone to the "angular torque method," as it is more accurate than the standard torque wrench.
Just got a (second) 2012 RX350. 13,000 miles. The Distance to Empty is confusing me. Doesn't come close to matching the tank size times either the mpg since last fill-up, or the overall average mpg. Overall mpg is 17.x. mpg since last fill-up varies from 17-21. But when I fill the tank, the DTE says maybe 260. With a 20gal tank the DTE after a fill-up should be in the 340-350 range.
This isn't happening on our other 2012 RX350 with about the same number of miles.
The needle gas gauge appears to be right, based on where the needle is before a fill-up and the number of gallons purchased.
Had my 06' into the dealer and the SA asks me if I want the TB and Power Steering Flushed. He knows me and I could tell he wasn't convinced it was worth it. Don't know how to flush the Power Steering Fluid. I've done the turkey baster method on my 330 but never the full flush. What PS fluid should I use?
View 4 RepliesThe two slow engine is starting to bug me. Acceleration from 0-50km/h is getting a little ridiculous. Any way to improve acceleration performance other than stepping hard on the gas pedal and make it rev. 4km rpm ? When I compare this with my gf's 2.5L Golf its just day and night difference.
I don't want a noisy muffler or anything like that. I have never modded cars before and I'm not planning to go down that route either. After all this engine is over 10 years old right?
My husband and I are considering getting a small SUV. We've narrowed our choices down to the 2012 Tiguan SE 4-motion or the CR-V EX-L AWD. I'm working on a pro/con analysis between the two. I've looked through some threads here, and would like to get some updated opinions from current owners.
Why would you pick the Tiguan over the CRV or vice versa?
I'm a long-time VW driver, so I'm naturally leaning towards the Tiguan. The Honda is slightly less expensive to start, and gets slightly better gas mileage, potentially translating into a few $1000s in savings over the VW during the life of the car. We have no real experience with Hondas. My mother has an Accord and decided she hates it after about 1 year. I do think it's mainly because she liked her Subaru and only traded it in because my father hated it.
Some more background info:
This would become my husband's daily driver and his Wrangler would become our third/weekend car. We're in no rush, and may decide to just keep the status quo. My husband commutes 40 miles per day, so better gas mileage is a plus. We have a Lab who will ride in the car pretty often, but we will buy a waterproof seat cover for the backseat of whichever car we get.
Has there been a proven methods for turning off the pesky seat belt alarm? I just recently picked up 2015 IS350 and I'm not a big fan of being told what to do, especially my car telling me to put my seatbelt on. My 2011 ISF was supper easy. I have done some digging and all I have come up with is that the dealer has to do it.
View 4 RepliesWe have a 2012 RX450h and it currently has about 60500 miles. These engines are direct injected correct? If so, intake cleaning due to carbon build up?
We also have a 2008 335 and it is recommended that these direct injected cars will require some kind of cleaning at some point in time. It seems that walnut blasting is the recommended method for bmw's but I can't say that I've read anything on these Lexus forums about intake cleaning.
I was looking into deleting the EGR ony '03 F250 and want to learn more about it. I was looking at the different kits and wanted to get the peoples opinion on what they went with, and how big a job it was to install, did you also do the oil cooler while your in there?
I was wondering if I could just weld the ends of the cooler off, stopping exhaust gasses, essentially deleting it, but valve and coolant still flows through. Amy downside to this?
Is there any difference between the 2010 v6 and the 2011- 2016 V6's ? Reliable? Highway gas mileage? Maintenance issues to look for? Is there anything you know that would keep me from buying this vehicle?
View 7 RepliesI bought a new 2008 ISF back in the day and acquired a 2009 M5 with 6,000 miles late last year.
My ISF has headers, exhaust and throttle control which absolutely changed the car from a Lexus to a contender, consider the mods with the following comparison. I enjoy my M5 a lot, it is my out of town car- drives great at 180, corners well, solid, roomy (being from Vegas I can fit 4 bodies in the trunk)..I can go on about all the positives.
However, the F is faster with the mods, better ergonomics, and has fewer repair issues. It feels like a go cart. It pulls the 5 until it hits the limiter. As there were only 500 or so produced each year.
Since i bagged my car and i didn't bought the swaybar end links to fix it it to my air struts, when i got it installed the swaybar got removed.
Now as my swaybar is off i might upgrade, my question is, Is an h&r front swaybar much better than an OEM one, and if yes should i pick a 26 or 28 mm o e (what's the difference, pipe size?)
So the LX and Landcruiser have shared platforms over the year but I've always wondered why Toyota / Lexus never released a stretched version of the trucks like an Escalade ESV or Yukon XL, etc? I know the trucks currently seat 8 people but the 3rd row is a little tight except for little kids. Also, if you have the 3rd row up, then the trunk space is all but gone. For example, with the Escalade ESV, with the extended version, the seats in the 3rd row are laid out just a little better than the 3rd row in the shorter truck version so it's a little more comfortable. And the trunk space in the stretched version is way more than the normal version.
Of course, the Escalade is not sold in other countries where it's seriously taken off road. I know that it's mainly a US vehicle that roams the crazy parking lots of many upscale malls whereas the Land Cruiser / LX570 is primarily the same in the US but it's also sold in many foreign countries where it really is used off-road and having a stretched version is not really the best for off-road maneuvering. Even so, I think Toyota/Lexus would sell more of these vehicles if they did develop a stretched version. Maybe call it a Landcruiser XL or LX570 XL..
Actually if Toyota made a stretched version, I'd say calling it a Land Bruiser would be more appropriate. I certainly would love an 8 seater LX 570 with the larger trunk area and possible better sitting space with the stretched version. Couple this with the Lexus quality and reliability and Lexus would give the Escalade ESV some decent competition.
In your opinion what looks better on a R. Classix or Denvers? Need to decide what i am going to run for winter.
