MPG Mods

Oh okay, I will have to add GPH to my initial screen and see. Thanks

 

I'm pretty consistent with high 20 to low 21. I completely re-did my exhaust system a couple of months ago to include: Thorley long tubes, dual exhaust, NO cats (thanks Florida!!) and have seen a slight bump in mpg under normal driving conditions but a good bump in mpg while towing my boat which makes sense considering the HP increase. My mpg when towing my boat would drop to mid 17 and after the exhaust upgrade it was mid 19. Now I didn't do the upgrade to get better mpg but am enjoying though

 

I was checking the info on the AFE air filters and the link to auto anything. Their site asks me the physical size of the air filter. My truck is new with 1500 miles on it I have not pulled out the filter yet... Anyone know the size of these off the top of their head?

 

its a weird shape:





05+ Tacoma 4.0 aFe Part number 31-10114 - Pro Dry S

 

Thank you.

 

Just wanted to let everyone know that I just recently discovered a great way to improve your mpg, especially in stop and go traffic. Get fuel injector cleaner and pour it into your tank before you fill up. For me I usually get about 200 miles per tank, after pouring the injector cleaner into my tank I am getting about 260-275 miles per tank. Keep in mind that for an $8 bottle of cleaner that's big savings in the long run. You should only use it once a month at most. Everyone is going to get different results based on their truck and how new, old, beat up,etc the engine is, but for those of us in 1st gens or frequently driven 2nd gens it should make at least a minor improvement.

 

What brand are you using?

 

Chevron is what I use

 

Chevron Techron is a good product.

But now I use Redline Complete SI-1 Fuel System Cleaner.

It has the most polyethyl amine detergents (PEA), the active ingredient in these products. From research I did, it is the best bang for the buck.

Either one is fine.

 

^ u find that in bobtheoilguy forums?

 

Sorry to disagree here but, I wholeheartedly disagree with any shelf bought cleaner increasing mileage 60/75 a tank.
Please be careful. Those point of sale items are not even considered maintenance worthy by the pros.
Consumer reports has done studies and maintains Gunk is meh at best and is the best of buying off the shelf.
I tend to use

$25 BG44k BG 44K Fuel System Cleaner Power Enhancer 11oz.

BG44k on my older vehicles once a year at most.
Look into a professional injector svc at a reputable shop and learn about your regional fuel, ethanol and the mix.
Sounds to me like you need to purchase better fuel as you are doing your motor no favors by adding that crap every fill up.
Best of luck.

 

I agree with you, I have tried everything to bring up the mileage with no success so I guess you just have to live with what you get.
By the way, I see you debadged your Tacoma, I did the same thing then though maybe I should put the TRD decals back on until I found out how much Toyota wants for them... $120 EACH..

 

When you say TRD decals, do you mean bedside vinyl stickers or TRD emblems?

Either way, both can be found for MUCH cheaper.

 

There are a couple very skilled vinyl sticker members that have and will produce anything you want here on TW. From TRD to personalized. They do excellent work.
Last week when I got home with my 2015, the first thing I did was removed TRD and every bit of chrome I could find. It made my lift fit better

Grill is off for color match and Homer Taco's Ghost Raptor mesh sexyness.

 

Well you know anything bought from the dealer is always 10 times the price of what you can pay on here and ebay etc.
Your ride is looking pretty sweet already, just watch out for buses ok..?

 

I made my first mod! I cut off the exhaust after the cats and installed a Flowmaster 50 Series Delta Flow muffler with a turn-down. I used the muffler with a 2.25" inlet/outlet and a 2.25" pipe. Looks like I gained around 1 MPG. (I also gained a great sound!) My highest MPG after the muffler is now 34.6 MPG!

I commute, so the long drive means the engine spends most of the time at operating temperature (which is most efficient). I have a very hilly drive, which is bad for mileage, but I coast downhill where possible. I also do a little hypermiling. Actually, that was my first mod. Changing the way I drove gave me about 2 or 3 more MPG. When I drive "normal", I'm usually under 30 MPG.

Next mod: I've got an LCE header waiting at home.

 

That is a strange success story with exhaust but I'm happy for you! I wonder how it would work on a v6.
As for hills,
Before the hill: Maintain speed or accelerate slowly.
Up: Decelerate slowly
(Optional) Crest: Accelerate back to speed
Down: coast, and right before it levels out get back up to speed.

I do this on the Rainbow bridge and usually it boosts my AVG MPG a tad.

From Google:

 

Why do you think it's strange? If you remove a restriction in the system, it's got to be more efficient. Easier for the engine to push exhaust out a less restrictive system, so there should be a gain in HP and MPG. It just might not always be measurable.

Interesting bridge. My hills are not as steep and are longer, but I use a similar technique. I try to hold same throttle position and let truck slow as I climb, and gain back the speed going down. If the hill is long enough and I'm going as fast as I want, I coast in gear for a while (depending on the hill).

The header is on, truck sounds great! First tank was the worst I've seen in a while (28.5 MPG). I was really enjoying the new sound! I drove "normal" the last tank and saw 30.7 MPG, about what I expected. Now I'll have to try to beat my old record. Oh, wait, it's gotten a lot cooler. That will probably hurt my mileage?

 

Putting a larger exhaust that's less "restrictive" isn't always an improvement. You need a certain amount of backpressure, and plus if less restriction=more mpg and power was the case, they would come with oversized exhausts from the factory. For that reason, MOST people show little to no gains with aftermarket exhaust unless it's a complete and expensive redo.

However, your data does show otherwise and I'm glad you have better MPG. As for the temperature I have no idea... Others do, but I don't. I wish I could say 28.5 was my worst tank!

Also glad your truck sounds good.

 

I got to see and ride in Dan's truck and he's really onto something. Getting gas mileage out of a truck that rivals passenger cars is truly remarkable.

The V6 would likely do well with the same Flowmaster 50 Series Delta Flow muffler, except with larger collars to accept the larger diameter exhaust pipe.

I stuck my head under his truck while he was revving the engine, and even with a short turndown pipe, the sound was so smooth with no rasp or rice. He doesn't have cab drone either.

Flowmaster mufflers don't use sound deadening material like other muffler manufacturers. They employ unique sound cancelling features in their mufflers, and that's why they sound and perform different from all the others.
