    I can tell this one, not so much. You can feel it loose power when you turn on the a/c.

    That's about as depressing as running into a wall with a boner and breaking your nose.

    'Demolition Derby' really does take its toll on a truck.

    Seriously though, my tundra came with a six inch intake filter that narrowed down to a 4 inch pipe. It didnt help at all on gas. I dont think i saw over 13.3 mpg, and that was only after i hit the reset button. Sure did squeal the wheels at every red light though.

    Changed it to a 4 inch and set my tire pressure. Been seeing 14.6 mpg.

    I like the truck enough to live with that.

    I guess it depends on how far someone drives per year, and how deep ones pockets are.

    Since I don't know Twinky's situation, and it never is polite to talk about someone else....so we can talk shit about me:D.

    We are going to take two situations to 200K miles each AND 10 years ownership.

    2016 GMC 3500 and 2007 Lexus IS350. Total investment between two vehicles is 74000.00. Could I have purchased a cheaper commuter? Oh yeah, and one that gets 10 mpg better....but racecar!!! Truck was purchased new, and Lexus was purchased used with 60K miles.

    First up, known truck maintenance and stats.

    Oil change, 65.00 doing it myself. I should let the dealership do it for 74.00. However, I'm a maintenance freak, and it has to be done right. (Pretty close to a Tundra oil change with 8 qts of oil)

    DEF fluid fill. I never fill all the way up, especially in the winter, but if I did, 5 gallons costs 22.00 and lasts one full oil change (5-6K miles). Not a Tundra issue.

    Fuel filter 35.00 (this isn't a Tundra maintenance item) every 22K miles

    Transmission service is due every 45-60K. I do this every 25K. Since I can do it myself with ease, 100.00 for two gallons of fluid and a spin on filter is easy. At the 45K mile mark, I have to replace the internal filter as well. No big deal. Another 12.00.

    Tires are 1200.00, and if I can get 40K miles out of a set on a diesel, angels appear in the sky and music plays. True story. I was about to squeak 55K miles out of tires on my Tundra. Diesels eat tires and shit my money out the tailpipe.

    My truck empty gets a solid 18-20 mpg empty, towing 11-14 mpg (8200 lbs is my lightest load, 9500 lbs is my heaviest at the moment until a gooseneck hitch is installed).

    Car facts:

    26-28 mpg
    Oil change 40.00 doing it myself with Mobil 1 oil and filter every 5K miles.
    Tires, 700.00 and they get warranted on the rear for sure. (offset tires and wheels, so no rotations)

    Driving habits:

    Tow 10-12K miles per year.

    Work and general driving around 20-25K per year. (95% of this is car, the other is Truck due to snow and what not).

    Known costs with two vehicles:

    Maintenance:
    - Oil changes (2 truck, 5 car) 330.00
    -Fuel filter every two years 17.50
    -Tires on truck is every 4 years-300 per year. Tires on car is every 1.5 years- 466.00

    1113.00 between two vehicles.

    Next up is fuel:

    Most people don't do what I do to get around 100.00 per month off fuel, so I will exclude this.

    12K towing per year at 12 mpg (diesel is 2.93 gallon)=2930.00
    25K driving car at 27 mpg (premium is 3.08 gallon)=2852.00

    Total fuel cost per year for just me- 5782.00

    After owning my truck for 10 years, I will be still way under 200K miles. At this time I can say F it, and get another or keep a perfectly good truck. lets just say truck prices don't go up...so I saved another cost of 58000.00
    The Lexus will be at 200K in just under 6 years. Now I can get something more fuel efficent or say F it, and get another Lexus (exactly what I will do), 16000.00 spent again.

    So now we have over a ten year period:

    74000 car and truck
    69000 fuel and maintenance
    6400=New used Lexus (only 4 years of service in 10 year window).

    Total cost is $149400 for 10 years and 200K of service. F me!!!:eek2:

    Now since I didn't have to buy another truck....and we are going to 200K miles, I could go another 7 years on a truck. Lets just pretend again that truck prices don't go up. So that is 5800.00 per year for 7 years, or 40600.00 saved.

    Total cost 149400-40600=108800.00 for being able to go another 7 years without buying a truck.

    108800.00 looks pretty good.

    Now lets do this with my truck only.

    12K towing 2930.00
    25K DD. 4578.00 (and this is average of 16 mpg mixed highway and city)
    Oil and DEF-652.00
    Fuel filter (1.5 times)=52.00
    Tires-1080.00

    Total cost per year=9292.00

    92920.00 fuel and maintenance for 10 years
    95700.00 in truck cost for 10 years.

    Total cost of DD my diesel 188620.00 for one vehicle and a partial new truck for 10 years. :eek:

    Now there are insurance and registration costs as well to consider. We also can add in that a diesel usually never goes 200K miles without at least injectors...2800-5K cost, and maybe a DEF tank or other emission issues. Injectors are usually 120-150K miles. I already have an injector fund going.

    Now if I purchased a used Corolla, the fuel would be half the cost, tires would be a lot less, oil changes would be cheaper as well.

    EDIT:

    I forgot the transmission services. So I will leave those out, and do what some people do...nothing!!

    I agree Jim, lots goes into the equation. Hell, paying for registration on a new vehicle every 2-3 years would make me sick.

    For someone that is a handyman, puts 5-8k miles or less per year would never see a return on investment.

    These are the best numbers so far. About 30 miles of freeway driving.

    I'm a Tacoma-owner looking at getting a Tundra. If that's accurate, I'd be quite happy with that. I'm only averaging 18 with the Tacoma right now.

    That was a one-time deal. Can't explain it, perhaps a computer glitch. I'm only getting between 13-15 average.

    Well, it's nice to know it might happen sometimes. :D

    I'd be happy with 15 too. I already figured if I was to average 14 mpg in a Tundra, at current usage and gas prices, I'd spend around an extra $50/month in gas with the Tundra. Cut out a couple of restaurant visits per month and that's paid for.

    Once you've driven a Tundra you won't go back to Tacoma. :D

    I own a 2015 tacoma and a 2018 crewmax 5.7. The fuel isn't really noticeable between them. My pops is 75 and drives tundras. I will warn everyone that drives "little old man" style that these trucks need to run. His gets plugged up every 6 months and drops down to 10 mpg around town. I grab it for a week, pour in some amsoil PI injector cleaner and beat the piss out of it pulling a trailer for a week. I unhook the battery after two days and let it reset. By the end of the week she is good as new and back to 14/18. I'm not saying to drive it like you stole it, but clean them out every now and then!!!!

    Just drove 6 hours this weekend. Averaged 15.6 for most of the trip, had about 2 hours or so of idling / stop and go traffic and a bit of city driving. Probably 16.5 doing 80-85 mph on the freeway.

    Mpg is hand calculated.

    Edit: tires are 285/55/20 everything else is stock and I’m about 1k mi into my oil change lol

    I had slightly bigger tires (32”) before I bent the shit out of one hwheel going too fast off-road and I couldn’t go over 14mpg Highway. I’m now back on stock wheels and tires, I’m leveled as well, I almost got 16 driving slow and retarded. I could get better driving longer and going exactly the speed limit. For the best MPG’s keep everything as stock as possible.
