MPG Mods

But overall finding something similar in your stock size will be your best net for mpg. It's not easy to go up in size and GAIN mpg, but myself and others have done it. I get above EPA consistently in the Summer and about right on in the Winter in this stop and go and hilly city so it's possible.

 

I have the same truck you have.

just bought some Michelin Defender tires, low rolling resistance 215 70 15 for $105 each. with mounting, balancing, tax it came out to $536 for four tires. But I get a $70 rebate from Michelin and also $30 for filling out the Discount tire Visa Card and putting the tires on the card.

Best deal I could find for a low rolling resistance tire. estimated to last 90k miles.

hope that helps

 

thanks

 

Hey Guys, Took out the filter last night and I can tell a real difference in power and engine response to putting my foot in it! Don't know about MPG's yet but I am happy with the change. BTW I run a K & N as well, gota breath!

 

I went with lightweight Enkei 16x7 5 lug wheels and high mileage low rolling resistance 235/60 Yokohama YK 580's (the 580 is the treadwear number which is high), and am enjoying 23-24 mpg city and 28-29 mpg highway. This combination retains the factory stock wheel diameter for an accurate speedometer and odometer, while being wider for better handling...





The truck rides quiet and smooth and handles great in the corners.

Very nice! Did you weigh the old and new to see how much weight you saved?

 

I went from 16x7 stock steel Tundra wheels with 245/75/16 tires...

...to 16x7 alloys with 235/60/16 tires.

That removed 15 pounds 4 ounces per wheel, for a total of 61 pounds of rotating weight. One pound of rotating weight is the equivalent of 10 pounds of static weight.

 

I have a 2013 v6 and my MPG is terrible. Truck runs great but 250-275 range per tank.
I'm planning to add a K&N 63 cold air next week but compared to my 98 v6 i'm not happy at all

 

what gears does it have in the rear?

 

That's pretty good! I will probably do something similar, but may stay with stock size wheels/tires.

 

I have a 2013 V-6 auto, MPG is not what i had expected or as listed.

I was thinking about adding a K&N cold air intake system to increase air and performance. I'm wondering if maybe just removing all of the factory filters and swapping out the K&N filters alone will help?
The stock system is a large intake compared to my old 98 model

 

stock from factory

 

That'll work fine as long as you retain the overall stock wheel diameter so that your final gear ratio remains the same and your speedometer and odometer stay accurate.


I used a wheel and tire specification chart and found that I could go with a combination of a slightly larger and wider 16 inch rim and a 60 aspect ratio tire, while still retaining the factory diameter.

 

Similar to your situation, I went from a 1996 model to a 2012... and found the newer truck to be larger and about 400 pounds heavier. It also had more accessories than I wanted, which I removed just as I did on my old truck. The overall mileage average on the 2012 is only one mpg less than the 96.

 

Do your research on the K&N air filters. Years ago I did and decided not to install one. Reason was that, even though it increases air flow to the engine, people reported that more dust/dirt got through the filter into the engine than when running an OEM type air filter.

Maybe they have improved the design since I was considering one.

Their oil filters are pretty good quality.

 

NEVER! AND i MEAN NEVER USE ANY GAUZE TYPE WASHABLE AIR FILTER!
(that goes for K&N or any other.
If you do, you will soon have shit loads of silica showing up in your oil.

Just always use a good paper filter

YOU HAVE BEEN WARNED!

 

Yeah, I've heard similar. They flow more air, but also let a little more dirt in. I tend to keep my vehicles a long time. 300,000 miles of slightly dirtier air may cause a little more wear. I'm going for a clean, long life.

I guess the best would be to have a really large paper filter. You still get good filtering and the extra area would cause less restriction. All I plan to do for now is to open up the air box.

Also, for better MPG, wouldn't a warm air intake be better?

 

The ECU will only let in so much air anyway, so better flow means near nothing.

 

Might as well post this again.


Air Filter has zero effect on mpg on computer controlled closed loop EFI. For like the last 25 years.

Simple explanation. The throttle is the overriding restriction if you are driving at anything other than full throttle at high rpm. The air filter is along for the ride, and if it becomes more restrictive with dirt then the throttle plate opens up further for the same output. At some point you might lose some HP with a restricted OEM filter, but you will never lose MPG.


You will never gain mpg with a less restrictive replacement to oem.

 

I think so... but then I'm the only one on this forum who runs a warm air intake.



...and I get very good mileage for a work truck that's always loaded down with hundreds of pounds of tools and material.
