Did Re-Gearing My Jeep Gladiator Affect the GAS MILEAGE?

[@TrailRecon]

It wasn't mentioned in the video, but yes I did recalibrate my speedometer to compensate for both the tire size and gear ratio. As for why I chose 5:13's, I think 4.88 is a good ratio to go with for a 38" tire, but because I carry extra gear and plan on doing some off-road towing I wanted to go slightly deeper, and that's why I chose 5:13'. Sorry for not explaining that in the video.

[@robertkeck2905]

TrailRecon I am concerned if the slight increased rpm (4:88) will move it up the horsepower curve enough to still pull 8th gear at interstate speed (75 mph). I realize I am on the verge of asking to much. You did confirm you see 8th a lot more with gear swap.

[@michaelnewman89]

What’s your rpm at 70mph in 8th gear ?

[@PhilGBeebe]

Thanks for answering my question before I could ask it.

[@brianmillican4985]

What did you use to recalibrate your speedo?

[@JeepGladiatorestAprilJTR]

I’m currently running 37 Pats, would you recommend 5:13s if I plan on building my rig similarly to yours as far as weight is concerned? Thanks Master Chief!🤙🏽

[@marnielarocque9412]

Wow, gentlemen, I am so impressed that i subscribed, I`m an old disabled mechanics and over the years explained or at least tried with some guys to explain what happens with bigger tires and gearing, and then of course, braking and shocks, so many other sites just add tires and never explain the changes in bottom end performance versus top end and real-life changes. Well done!

[@expert244]

The MPG gain wasn’t super impressive, however the increase in MPG PLUS the extra low end power is a win IMO.

[@rareearthfab5511]

Great Job Brad! I do a lot of gears for people and explaining what you have found in this video people don’t believe me. Not only do you pick up a little mileage but it’s so much more fun to drive a properly geared 4x4 on or off road.

[@TrailRecon]

Thank you! Great to hear you are seeing similar result!

[@MattsCollection]

The added weight of the breakfast burritos has made this test invalid! :D

[@xTinBenderX]

Had a 26' Penske loaded and towing my CJ7 on a trailer. The truck's rear tire developed a bad vibration over 50 so I had to drive from LA to OKC doing 50. I got 8 mpg before the vibration and 16 mpg after. Lesson learned about pushing air.

[@built4xploration253]

Was cool seeing my old stomping grounds. The tower ( really the caves) holds a special memory for my wife and I. Oh, and holy crap, I cant believe 87 is $4.03!!!! I am reminded of one of the reasons I fled CA.

[@tjshine8022]

Wow, I called it at 17.2mpg! On my 96 Chevy, 350 AT, 35" BFG's and 6" lift I went 3.73 to 4.56 gears and went from 17mpg to 18mpg on the highway. But City went from 13 to 15 because the lower gears made it easier on the engine to get to speed. Gears will help your engine and mileage, it may just take a few years of driving to make up the $2,000 price of them. Great study!

[@ensignwiggles87]

[@robpedrow9293]

Great video with some good conversation about all the things that can go into ruining or increasing your gas mileage. I think people don't realize how big a difference regearing can make when you jump more than a couple inches in tire size from factory. One of the first things I do to my vehicles now that get more than a small bump in tire height.

[@TrailRecon]

I'm hearing the Wrangler diesel is going to blow the mpg I'm getting out of the water!

[@BackroadExploration]

Love your Gladiator build! Impressed with the MPGs you are getting. I’m getting around 17 on the Highway in my JK. But average around 15 on all around driving including Overlanding trips.

[@JustNobodyButME]

The question will be,"will the mpg on the diesel make up for the increase in cost per gallon?" Of course the diesel engine will outlast a gasoline engine by a long shot and have better overall performance and for those reasons I would go diesel every time.

[@45auto]

My question is how will it take to recoup the additional cost of the diesel engine? Obviously, the cost per gallon is the big factor but how many gallons? There has to be a math whiz out there who can figure that out for us Liberal Arts majors.😀

[@gogerwi]

I've owned 7 Jeeps, all just minimally powered. The diesel is a $4000 option on the Wrangler and diesel cost .40 more than gas. For my personal satisfaction and driving pleasure I will pay the extra cost regardless. Life is short and you can't take it with you.

[@jeepwrecognizejeep1391]

There's a fine line between making a KZbin channel successful and selling out. Where does one draw that line and find that balance? Started from scratch and as a channel grows the more sponsors it attracts. The more sponsors one gets, the more it starts to look like an infomercial, biased and unorganic. Then along comes the haters and trolls. How does one know where to draw the line before their channel gets too big to the point where the content becomes unrelatable to the average Jeeper?

[@kennrymdeko6489]

Great explanation of regearing. I regeared my 2017 Tacoma DCLB auto this year and finally found 6th gear! MPG improved by approximately 3 mpg overall since it could finally find cruising gear. And the transmission hunt finally stopped too. Great video Brad.

[@kennrymdeko6489]

Oh, forgot to mention that I didnt recalibrate the speedo. So probably increased MPG a little more. Just running 33's tho.

What a shock to me that you improved your gas mileage! Back in 1969 I had a Z28 Camaro and put 538's in it. Gas mileage went way south! Made the mistake of driving it from Okla to Indianapolis once. Gas was like 32 cents but I was only making 2 bucks an hour. It got to 60 really quickly though! :)) I know the situations are different and tech is different, etc etc, but I was still surprised at your gas mileage improvement.

Modest gain in mpg. Cannot use that as justification to regear but other benefits still make it a worthwhile mod. 👍

re-gearing has been hands done one of the best upgrades ever. We got the Jeep with 35" and it always lost power uphill. Still breaking in the new 4.88 but it is exceptionally noticeable the already better MPG in slow driving around town and it feels stronger.

2008 JKUR.. Dealer had put 35's on it already w/2.5"lift. Stock gears were the 4.10's. Pulling a trailer at 70 mph on the hiway, only time it would get out of 2nd gear was downhill. I went to 5.38's (also cryo-dipped them) and I at least stay in 3rd now. W/O trailer, even the OD stays in better. Ya, is the 3.8. But my mpg did come up too.. Varies on what I do, but 1~2 range is common. And yes, I is much more spunky both on street, and crawls crazy great.. Thou, off road, I have use the programmer to set to crawl mode. Too jumpy if don't.. Hiway mpg.. Around 15±. Have been into the 16's under ideal conditions a couple of times. 12.5~13 common around town. All is better then with the stock gears.. 63k on it currently. Gears were put in at 10k.

[@daveputman4402]

The next time you are in a gas station, look at the nozzle on the hose, you will see a 1/4 inch tube in there, because of CA emmissions, that tube is designed to suck the gas back out to keep it from going into the atmosphere or on the ground. Every time you click the handle after the auto shut off you are putting gas back into the ground tanks of the station

As a general rule, to stay safe you should pace yourself, not overexert, rest often, drink plenty of water and eat regularly throughout your hike. There are, however, some specific injuries and afflictions that you need to be aware of so that you can deal with them.

[@jasonveldhuis9471]

In 01 I bought a new gutless 1500 ram 4x4 with a 360 magnum engine. 3.55 gears got 11 mpg max. Tranny blew at 20k, factory reman.Put 33” tires on and got 9 mpg and more gutless. Blew the tranny at 40k. Put 4.10 gears in with a hand built tranny and got 12 mpg, more if it was unloaded and I milked it. Even when it was all stock, it struggled to stay in 4th gear. The 4.10 gears were way better and the transmission lasted another 200k when I sold it for scrap because I live in Michigan and the salt ate it up. I did sell the transmission to a friend of mine who put it in his plow truck and ran it for another few years. I still should’ve went with 4.56 gears though. Those 360 magnums were worthless!!!

Temperature, humidity, altitude all have an impact- they were wearing jackets in the 2nd test cooler dense air yields better combustion.
