    Currently my baby is at the dealership getting the frame replaced. With gas prices getting up there im getting ready to give back my rental camry for my 2.7 4x4. The camry is getting like 36 mpg and last I checked my taco was getting about 20. I am really considering doing some extensive yet simple mods. First im thinking about replacing all of my fluids with royal purple. I saw a shade tree mechanic or trucks show a long time ago and they gained power and saved gas by doing that to a big dodge if im not mistaken. Were talking all of them tranny, t-case, gear, and motor oil. Next im going to do the electric fan mod. It just makes sense to take off parasitic parts if you dont really need them. The fan is 325 on summit.com but i think it would be worth it in power and mpg gains. Then I will attempt the airbox mod and see what happens. Then when i get a little more cash replace the exhaust with perhaps a gibson setup. I have toyota putting on some bilstein hds because they were going to charge me 125 a piece for oem toyota shocks. Oh i need some new tires too. Ive seen some pretty cool posts about tire weight and rolling mass. I am looking at firestone destination ats right now because they are capable, inexpensive, and light weight compared to many other at tires. Any suggestions would be greatly appreciated.

    Just out of curiosity, did they do a before and after dyno on that Dodge?

    Just a warning about synth. If you have installed a posi rear end, you probably do not want to run synthetic in it because it will cause slip and chatter.

    Lol g35 is neither cheap nor good on gas. If you are serious about mpg don't get an at tire; get a hwy tire instead. I would do the deck plate mod first because its the cheapest, but truth be told best way to save gas is the lead foot mod.

    Buy a calculator. Learn how to use it. Calculate exactly how much better mpg you will get with these mods, and what that translates into, in terms of actual MONEY. compare that to the MONEY you will be laying out for the mods. Don't buy the mods, and spend your time/money in happier pursuits. People get all wrapped up I'm the mpg numbers, and never take the time to dollarize them.

    First of all im no leadfoot by any means. Second of all I dont need a calculator to figure this out.

    Let me "dollarize" this for you.

    350miles divided by 18gallon tank = about 19.5
    368miles divided by 18gallon tank = about 20.5

    1mpg in 20mpg is lets see... oh 5 percent. So id be getting 5% better gas milage by saving 1mpg. 2mpg 10%!!!! 3 15% 4 20%

    This is where i need the calculator .

    If i drive 350 miles a week and get 19.5 mpg I will drive 18200mi using 936 gallons of gas at 3.50 per gal = $3276 per year.

    if i drive 350 miles a week and get 20.5 mpg i will drive 18200mi using 890 gallons of gas at 3.5 per = $3115 per year.

    If i drive 350 miles a week and get 21.5 mpg i will drive 18200mi using 848 gallons of gas at 3.5 per = $2968 per year

    If i drive 350 miles a week and get 22.5 mpg i will drive 18200mi using 811 gallons of gas at 3.5 per = $2838

    So going from 3276 dollars a year to 2838 dollars a year is a savings of 438 dollars per year IF gas stays at $3.50. Today its at $3.60.

    Now what kind of mods could you do with at least 438 dollars?

    You proved my point exactly. The fan alone is $325, not to mention all the other stuff you talked about, and you might save $438 in a year, if you get 3 more mpg? Throwing good money after bad, but that's just my MBA talkin'.... :D

    No one is being a smarty pants, you need to really look at the numbers. Even with crazy gas prices, you aren't going to make up anything here. The tacoma is pretty well optimized as it left the factory, assuming you leave it as it left the factory. Make sure your spark plugs are good, fuel injectors clean, tires properly inflated, and everything is spinning freely. Biggest difference you can make is your driving style. It can't be said enough.

    That being said, I went through all the above issues and picked up a pretty significant improvement. I bought my taco about a month ago, and first few tanks were in the 17-18mpg range with mixed driving, 60-70% highway. Last tank was 21.9. Aren't going to do much better then that with a 4x4 truck on 31" AT tires. Beats the pants off of the 13-14 I was getting with my K5.

    That's a buck twenty-ish a day. But, the price of oil continues to increase at a fairly rapid rate. Around here, we've seen an almost 50 cent a gallon increase in the last couple of months with no real sign the price is going to stabilize anytime soon.

    You'd be better off getting a scooter for the little stuff around town and going from 18-20 to 40+ mpg.

    Keep your tires properly inflated, easy on the skinny pedal, keep your bed and cab as empty as possible, and keep your tailgate UP. These are the cheapest, easiest things you can do to lower your fuel bill. Synthetic can offer extended drain intervals and increased mpg. Other mods have minimal effect vs cost.

    Well whenever I get her back from the stealer I am just going to do the full synthetic switch. They say that summer blends of gas get you better milage anyway so we will see how things go. Like i said im just thinking about doing this stuff. There are extra benefits of getting the electric fan besides mpg. Its more efficient and its not leaching off of the engine. Id much rather pay 325 for it, than a cold air intake which does nothing for most taco owners.

    I would love to know how much difference the synthetic fluids make. It would be cool if you did a real good mileage assessment after each mod you do. It would be some very useful information for the rest of us.
