    Please consider the following:

    6000/miles a year (assuming HALF your 12,000/yr miles driven will be highway)

    6,000/miles a year divided by 16mpg=375 gals of gas 375x$4.00/gal for gas=$1,500.00

    6,000divided by 20mpg=300 gals of gas 300x$4.00/gal for gas=$1,200
    Assuming 10 year ownership
    ==================================================

    Chuck, it's not as bad as you are showing
    I have been driving my old car instead of the Silverado much of the time. I would normally drive around 15,000 per year. My Silverado overall gas mileage is so bad that it loses around 4 miles per gallon for each gallon used. (sometimes it gets closer to 14 MPG city.)

    Miles per year - 15,000 @ 16 MPG = 937.5 gallons
    15,000 @ 20 MPG = 750 gallons
    _____
    difference of 187 gallons x $3.50 = $690 approx. per year x 10 years = $6,900

    That’s roughly $7,000 more for me to drive the same truck you're driving in the same time period. I didn't count on that when I bought it.
    However, if I had as much money as you seem to, I might not mind throwing it away for the pleasure of driving this fine truck.

    String-all your driving is not done on the highway though. So you can't figure the total 15,000 annual drivng as being on the highway. The mpg difference is on the highway. So the difference in mpg is on the HIGHWAY ONLY.

    My mpg in the city will go down to 14mpg under the right conditions. Heavy traffic, high temperature, idling, etc.

    The sticker for city says 15/city

    So that $7,000.00 would be $3,500.00

    If you bought a replacement vehicle for $25,000.00 then at 6% (tax,lic.,etc.) your total will be $3,750.00 in taxes.

    Where are the savings? We are not even talking about depreciation and such on another vehicle.

    Sold my Silverado back to the selling dealer and purchased a Ford. 16K Loss, but Im happy, and no hesitations / surging. I had a co-worker drive the truck back to Chevy from the Ford dealer, a 42 Mile drive from where I purchased the Ford. He had no idea why I was getting rid of the truck until he drove it. By the time we got there he was extremely annoyed at the performance of this truck, and said he would never buy a Chevy truck after driving this one.

    Congratulations on your new truck. Your happy that is all that matters!

    Thanks Chuck for the info,
    I live just outside the Houston city limits. We have lots of freeways and beltways around Houston.
    I guess I am referring to "City Mileage" the wrong way. Probably at least 60% of what I am calling city mileage includes high speed Loop and Beltway miles. I guess it should be classified as City & Highway combined to get that 15 MPG. Strictly slower (city street) speed driving would be less.
    The 16 Mpg is filling up at the gas station and getting directly on the Interstate taking a 300 mile trip. That adds up quick!
    Also, in Texas the vehicle sales tax is 6.4%, which is $1,600 on 25,000. However, if you finalize your negotations with the vehicle dealership, then see if they can meet your best acceptable offer from elsewhere. Here in Texas you won't have to pay taxes on that amount if you you use it as a trade in on the vehicle you are buying. You would only have to pay taxes on the difference between your trade-in amount and the new vehicle price. So, the way I see it, my previous post is still valid.

    I think I'll be happy to quit feeding that Chevy gas guzzler too!

    Thanks for all your help, and good luck in your crusade of support for General Motors

    That's a good deal on the tax. Yea, I incorrectly calculated the taxes on the 25Grand. It looks like the mpg difference could make it worth while then. So I am assuming you will be looking at a Crossover or car?

    You never mentioned anything about the need for towing.
  • I got rid of my RV, but I still have the rental properties, so I won't need a full size truck. I'm thinking about maybe a crossover. Possibly a Honda Crosstour V6 to pull a trailer very infrequently. The're good up to about 1,500 lbs. Do you know anything about them, other than how ugly some people think they are?

    According to a leading consumer magazine (you know who I mean), here is a quick sample of rated and actual mixed MPG in their tests.
    EPA Overall/mixed actual
    Silverado 5.3L 14/21 14
    Tundra 5.7L 14/18 15
    F150 5.0L 14/19 15
    F150 3.5L eco 15/21 15
    Ram 5.7 13/18 14

    You can draw your own conclusions. I have a 2011 5.3 L and get about 15 MPG.

    Hondas are good cars. I just traded in an '07 Honda Accord EX-L w/the 4 cylinder that was flawless and had 102K on it., but needed an AWD car for the winter.

    The dealer gave me $12,000.00 for it. I traded it in on a new 2012 Subaru Legacy Limited.

    As far as the Crosstour-I cross shopped that with the Subaru because I already had the Accord and it could be had with AWD. To be honest, I felt they were over priced for a vehicle which is admittedly a poor seller.

    From a reliability standpoint I would recommend them. From a eye appeal and resale (Honda will tell you they are a Honda they have good resale-but the fact remains they don't sell very many at all) value standpoint I would stay away. The choice is yours.

    Thanks [non-permissible content removed],
    Man that sucks! EPA might as well shut down if they can't do any better than that.

    That mpg figure for the Ecoboost is a big disconnect on what is being reported over on most Ford Eco-Boost forums....it's higher.

    I have a 2012 silverado 4x4 with the 5.3L and Afm only activates going down hill. I average 12mpg around the city and on my straight trip to orange tx I averaged 17 after adding a programmer. all 400 miles were at 70mph. My truck surges really bad when slowing to a stop I'm guessing its the Afm kicking off. Before the programmer it'd average 11 in city and 16 highway. I feather the throttle and watch the instant mileage to keep it high as I can. That's doing the math at the pump. Now have 12,000 miles on it. Completely stock minus dual exhaust. I'm extremely disappointed had I known this I would have bought a tundra which is what I really wanted being they beat the Chevy in everything. Way more power. Only reason I steered away from the tundra is the crappy mpg which turns out the silverado gets just as bad or worse. It's not that it gets such bad mileage what pisses me off, it's the false advertisement. This will be my last gm

    And the Tundra would have cost you $5.000.00 to $7,000.00 more which in of itself will buy ALOT of gasoline.

    I was given "Reduced Engine Power Message" last night.

    I could not go more than 10mph up hill and no more than 30mph on flat ground.
    The bed was empty with just the family seated in the car. I was worried.

    SOLUTION: Chevy has issued a "soft recall". There is an official letter letter that states Chevy knows of the problem, BUT WILL NOT FIX IT UNLESS YOU ARE SOL. Chevy will cover the problem, should it arise, for 10 years or 120,000 miles, whichever arrives first. It involves the throttle body and the computer that regulates it.

    I am not happy, my vehicle is "sick", but at least Chevy should fix it for free.
