I always get asked what the fuel mileage on my truck is. In fact, its multiple times a day! So in this video we go over what I get and how I can achieve such high mileage on 40" tires! Workforit Gear: www.workforitapparel.com
While service manager at a Chevy dealer I had a 15 2500 diesel high country come in. Customer had all the emissions deleted and a tune with no other modifications. I took it on a 30 mile drive on the highway and the gauge showed 30+mpg the whole time. Obviously I didn’t fill it to double check the gauge, but I am a believer. Only thing I was worried about was longevity of the engine, but the truck ran great. The owner said he literally had the work done for fuel economy purposes. He towed a 10,000 lb trailer everywhere and got over 20 mpg towing.
I've seen 24 out of an LBZ, yes it was calculated by fuel in, and miles driven along a known route. EGR delete, downpipe, 5" MBRP kit, EFI LIVE, DSP5 switch, stock tires, stock ride height. It is possible to tune it that way, and this wasn't the most fuel efficient set up, but it was a 6 hour drive going 80mph with the A/C on. Just requires parts and tuning for mileage vs power.
jmax7733 same here but I'm on 34x12in tires on heavy ass 20 in wheels. A 120hp tune but I've got a pusher y bridge and cold charge pipe. I got 24.2 at best.
when i had my lbz i only got 16.8, however it was lifted 8 inches and on 40s. had pretty much same crap you had, i now have a cummins 4th gen fully deleted pretty much same as your lbz and only get 18.3, super miss my lbz.
same here I have tuned 16 lml, same tuner as this dude, stock wheels tires, ez lynk/y bridge/ hot-cold piping/ fass/ 2in up pipes, and I get hand calculated on the hwy 80mph Cruise max 21 to 23 with no hills or wind
I hate to pee on your parade, but there is no way in hell you're getting 26 mpg with an LML with 40 inch tires. I own a 15 Denali Duramax, an 02 SLT Duramax and had a 14 Denali Duramax before that and I've sold Diesel Performance parts for 15+ years. I concur on the BS. 26 mpg would mean that you're getting upwards of 900 miles out of your 36 gallon tank. It would be VERY hard to do it with stock 265 tires. The best I've seen recently is a 2013 LML getting 22-23 mpg on LONG hwy drives with stock 265's. With bigger, heavier 40" tires, lifted up in the air, its getting MUCH worse. I'd guess you're really at 14-18 mpg MAX. Since you gave no details on your calculations I can only assume that like most people, you have no clue how to calculate mileage. many people look at their "instant" MPG coasting downhill with a tailwind and think they're getting 25-30 MPG. That is NOT your average MPG. To get your ACTUAL mileage start by filling your tank up to the neck which should be about 33-35 gallons in that you have a 36 gallon tank. Next, clear all of your averages on your heads-up display. The LML's are very accurate on the dash computer, but you'll still want to compare to your ACTUAL hand calculations. I'm also assuming that you had your tuner corrected for your current tire OD. If not you're likely cheating yourself out of some mileage. Now DRIVE till nearly empty. If you you approach 600 + miles per tank I would be very surprised. If you do have a one in a million truck that actually gets 25-26 mpg with big tires I'll gladly eat my words.......
Was looking for info on this for fuel mileage and came across this video. Nice truck. The gas station you're at is always crazy, been going there for years.
Stock Economy Econ/Tow Street Max I run the same tuner and full delete kit from PPEi. 5" lift on 35's and the best I have seen is 27 mpg in the econ/tow mode.
I love all you people doubting this... pre all the emissions crap that was pretty common. My 2004 cummins (early 2004, the emissions stuff started 2004.5) (crew cab, long bed 7800# on 37's with a similar tune to his) can knock down 24-26 in local driving (DC metro, we get some crap traffic) if I'm being very careful, and I've gotten as high as 28 (on some hilly backroads).
I once worked in a factor doing that.. packing boxes. At the start of the video your were having a hard time with your tape... you can get a little tape despencer off ebay.. the front has a sponge that you fill with water and a rolling mechanism that holds and pushes out the tape with a push of a lever...
Ty Bigos I understand you don't know what your talking about but I have an 2007.5 duramax crew cab 8ft bed 6" lift on 37" tires, EFI live tuner, 5" full exhaust and I get around 22mpg highway. you get better gas miles with diesel.
Dgozz122 lol. I'm A manager for a diesel performance company.👍🏽 I know a thing or two. So I highly doubt both trucks mpg and if that was the case you guys should probably contact Guinness book!
Ty Bigos well if your a manager of a "diesel performance shop" and you don't think 22mpg is possible you sir should be fired. Do you drive a diesel truck as a daily or are you just going off what people tell you? i drive my truck every day so I know what kind of highway mpg it gets.
Actually it's not...I have a 2016 GMC 3500 Shortbox Crew, which is getting 22.8 to 23.1 stock on stock rubber, stock tuning, all miles. So...I suspect, tuned, with water injection and deleted, it could be done.
I would believe the 26 mpg if you checked each tank at the pump on the receipt and not off the computer.. I get 23-24 tops without 40's and I have all the deletes, down pipes ect..
Donn Worry exactly. You can't go off the display. Hand calculated, this might be around 15-17. Haha I got 11" of lift and 37's with 2 less cylinders in my Cummins, hand calculated, about 16 highway.
Anthony Joubran even after deletes and tunes, it's not gonna get that fuel mileage in factory form. 😂 this was probably just clickbait. My truck doesn't have any of that emissions bs, 11" of lift, 22's on 37's and 2 less cylinders and averaging 14 in the city. Around 17 on the highway with EFI Live.
Anthony Joubran yes I have 5" turbo back MBRP exhaust, injen intake, h&s tuned, stage 4 transmission, I run 285/75r17 so a lot smaller tire so I have less weight and with no wind I get 24mpg tops
The diesel lane block is a pet peeve for me too, as I pull a travel trailer, and going in between pumps is an issue for me anyway, the end pump is a must!
That's if you're easy on the pedal and going down hill at 65 mph, heavy foot and going 75+ even stock tires 2wd you'll get 20 mpg on your best day. And that's in a 15-17. Now if you regear, delete and tune it you might see a 3-4 mpg increase but nothing crazy like the dude in the video is claiming. You likely wont even get 20 mpg on 40's WITH a regear, delete and tune.
Got my work for it sticker the other day. Slapped it on the back of the 6.0 and I've had so many people asking about it and where I've got it and I gave 2 people those little business cards but I ran out so I've been telling them to just check you out on Instagram. Great vids man keep it up
Lifting it changes the gearing because of the bigger tire radius. It's possible that lifted trucks actually get better MPG's ironically but less torque when towing or getting out of the hole 0-60.
Turning fewer RPM's doesn't guarantee better fuel mileage. If your tires are too big, going smaller will give you better mpg's. If your tires are too small (they'd have to be insanely small, or you'd have to have extremely low gearing), then bigger wheels and tires will help. Same with gearing. If your tires are way too big, you can actually GAIN mpg's by going with lower gears and turning higher RPM's. Both tire size and weight have a monumental impact on fuel mileage and your gearing needs to be whatever puts the least amount of stress on your engine and combination, given the circumstances (tire size, tire weight, vehicle weight, transmission, use, etc). And tire/wheel size/weight DOES indeed matter at all times, not just first gear. It matters far more than vehicle weight, and if you can imagine a 50,000lb Corvette, it would be extremely slow in a roll race and get terrible gas mileage.
I like your channel dude. You're blessed to be in SD. I used to live in East County and O.B. as well. Bought a condo in the good old I.E where I'm from but I miss it down there.
just took trip to maggie valley nc from Florida 21 mpg stock. doing.. well above speed limit... i can see 25mpg to 26 if u do around 65 with delete and tune
Wright down your mileage when you fill up and do the math. Bigger radius on tires will change your speedo accuracy and add a load on any vehicle to which will bring down mileage per gallon. Your dash mileage meter is a bull$hit liar and confused because of the changes you did to your drivetrain. However, diesel will always get better mileage over the same vehicle if it was gas. He is probably getting around 12 to 15 miles per gallon. If it was gas, he would be around 8 to 10 mpg.
maddmark1 agreed I laugh when people tell me how much they are getting. dash mileage computers are never accurate. my lbz says regularly I'm getting 23 mpg. that's wrong hand calculated I'm getting 17-19.2 depending on how and where
Fredrick Foster You are both correct. You are CORRECT And The computer is correct. The computer added each shot of fuel that each injector is injecting into to each cylinder, and then adds up the total. This is the correct amount of diesel fuel injected. You are CORRECT, on MPG. WHAT IS MISSING IS THE AMOUNT OF DIESEL FUEL THE PARTICULATE FILTER BURNS. FUEL INJECTED TOTAL = FUEL TO THE CRANKSHAFT + FUEL THE PARTICULATE FILTER BURNS. SO BOTH YOU AND THE COMPUTERS ARE. CORRECT
Theirs a good reason y the rest of the world except US and Canada use diesel for most SUV and Trucks. To increase the amount of oil consumed here. Toyota, Ford, Chevy, Mitsubishi and Nissan all have small diesels that have been arround forever in trucks and SUV's. Just recently Chevy started to offer the diesel built in Thailand for the Colorado. Those Toyota D4D and Ranger 5cyl diesels are an amazing engine when you ride in one but would break our gas job scam going on.
5 years later, are you still holding on to diesel? I’m a fan of it more than unleaded because it produces more fuel efficiency as well as power. But I’ve never owned one so I can’t say from experience.
Did u program your truck's speedometer for those size tires so the math is correct for the mileage. Having a talk with buddy and we wanted to make sure. Thanks.
After buying a set of Bridgestone tires at Firestone here in st. Charles, Mo. a few years ago I went back to get the free tire rotation as promised and was told they don't do that . . . So! I called Firestone yesterday and a lady answered the phone at firestone and I asked about the reason for this and she said they do give free tire rotation if you purchase a new set of tires. Obviously, somebody is lying.
I would like to know what all you have done to it and the elevation you're living in? I have a 2013 Denali 2500HD that I have deleted and I have an EZ Link tuner running the same 150 horse tune on a stock suspension and I average 17.25-20.5 mpg depending on time on highway versus stop and go of course, those are hand calculated numbers my digital instrument cluster is always 1-2 mpg higher. Would love to see those kind of fuel numbers though.
I have a LS1 swap in a 65 C10, it gets 30.5 mpg on the highway, 22 mpg in the city as long as I stick to the speed limit, it's hard to do with almost 400 HP under the hood.
can I get a break down of everything you bought and upgraded your truck with, my mpg is horrible. also, do you think I'd be shooting myself in the foot if I didn't upgrade the exhaust
I have the same truck kinda mines a denial 2017 3500HD with 13 wides on 40s and a 14 inch lift mine is all white expect for the rims. Got it as a gift from my wife.
I have a 2014 5.3 v6 with everything stock. I know I should've got the v8 but I got a good deal on this truck. What can i delete or do to get better mpg? Right now I average 17-21 mpg
24-29mpg 2015 Ram deleted Cummins 4x4 quad cab camper shell loaded 6 Speed G56 average MPGs went up 4-8 MPGs, 3 calculus! Garmin, Android, Google maps & RAM computer! Delete & KN air filter, 9500lbs, 80lbs cold Tires! Now at 125,000! delete at 80,000 miles
Putting 40's and leaving stock gears lowers the hwy rpm and will get you some mileage gains on a nice flat road. The big cost is your trans taking the extra load.
I have a 2002 F350 7.3 Diesel, I can not get a tuner like yours thru the company You go thru, What company do You say is Best for my 2002 7.3 Diesel ??
Im gna ask a lil pre emtively , before i watch ur other video & it might seem stupid to some of u guys who may already know, but can i use ur method & what u did to ur truck on a gas suv? Ive got an 01 GMC yukon xl slt 4x4 its got a stock 5.3 ltr vortec in it. & im getting roughly 14-15 mpg's give or take 1.5 - 2 mpg?? Thanks in advance for w/e kinda knowledge u guys throw my way.
I got 38 mpg put a dollar store turbine in my intake, oh I have lbz, stick with the stock 245/65/16 put zmax in, made a box outta a cooler for ice, just before it goes into my turbine, then turbo, I bet I can get 44mpg with a few more mods, any opinions on what else I can do to get better mpg.?
Chris Cook then you need to get rid of your Cummins and get a real truck! na just kidding I don't have a problem with dodge...but I'm willing to bet he might. I got a 2012 lml leveled on 33's and I get 24-26 on the highway...and that's in Tennessee where the roads are a constant hill! he's running bigger tires but the flat ground probably just about evens it out
drtydmaxxx. Thanks for the comments. I really do check my mileage on every fill up by hand. I get 23mpg on flat ground going 55 mph highway only. Everything else is down from there. Especially if it is windy. Do you have a chip? Delete? Just curious.
Chris Cook yea my truck is deleted, straight 4 inch downpipe back exhaust so no dpf/def crap, egr is still in place but it's completely deactivated and turned off. I've got an efi live stock delete tune...so it's still stock horsepower, just tuned to let the truck run with the dpf delete and to turn off the egr system. I think the stock delete tune does kinda tweak the fuel curves and rpm parameters to get the most out of a gallon of fuel that the truck possibly can tho lol
Have a 2016 ram 2500, full delete, 342 gears in a 4x4 megacab. Easy 28mpg at 72 mph. Tow my 30’ toyhauler at 16,000lbs. At 65 mph and can average 13-14 mph hand calculated. Amazing when you open up this motor how well it does. Oh by the way I have the 6.7 cummins. Thx.
Both both ford and ram make a great diesel truck these years, I personally prefer the ford primarily for the 10spd that's been proven reliable and its new upgraded exaust brake. I think there is a reason huge fleets seem to prefer them.
people here in nevada mavrik stores like to park in the pump spots and are not getting fuel they even park with the filler hose on the opposite side of the vehicle
Yeah my 2013 Denali w stock tire a air filter and Nitrogen tires I would average 18.7 on the low and 25.6 on the Highway if I would of done a few things i could of got better. But the down side is how much it cost to fill up and if you dont keep it full they dont as good of Mpg due to sloshing.
2004 extra cab long bed Cummins AC and cruise on. At interstate speeds empty I'm around 10 or 11 miles to the gallon and that's actual fuel test filled to the very top I write the mileage and gallons down. I do the same with the next fuel receipt. And I cut miles and gallons in half to figure fuel mileage. My truck is all stock except for an air cleaner that come on it. I got 42.5 miles to the gallon but here's the catch. I was only running 40-44 miles per hour on long runs. Yes it takes forever to get somewhere but I never have to stop for fuel. RPMs around 1,050 - 1,150 about. The biggest thing with fuel mileage is slow those RPMs down with taller tires, slower speeds, gear vendor or better gear for gas mileage like in the 3.50 range 3.00 or lower. And for gas mileage no jack rabbit starts or punching it on the road. Especially if you have a newer truck with 800 - 900 foot pounds of torque. My truck is 305 horsepower and 550 foot pounds of torque. And mine is 3.73 rear gears. Around town I use to get about 10 to 11 miles to the gallon. Around town I started shifting my truck at a 1,000 RPMs it's a manual 6-speed. Most of the time I'm in 6th Gear by the time I hit 25 miles per hour. My best fuel mileage receipt is almost 19 miles per gallon. And yes shifting at a thousand RPMs the truck is very slow out of the hole slower than a tractor trailer. But it's less wear and tear on things and better fuel mileage. Of course when I pull a big load I can't shift that low I have to shift higher in RPMs in the heavier the load the higher the RPMs I have to shift and fuel mileage falls off. Drifting in neutral off of every hill helps fuel mileage. And shutting the motor down at stop lights in the day only helps fuel mileage to. I do not shut the truck off at night at a stoplight because it pulls on the batteries. Slows RPMs which equals slower speed will get better fuel mileage in anything. If you drive for a company and doesn't care drive it like you stole it. But if you drive for yourself and want to save wear and tear and fuel mileage drive it easy.
Question for anyone, how do you get by all the state emission test after you Delete? what are the best Deletes to do? I am buying my first Diesel soon and I am researching for personal use.
I have a 2013 Chevy Silverado 2500hd gas truck and I get anywhere from 10 miles a gallon to 11 or 12. I was curious if it is possible to get into the 15 or 16 gas mileage range?
I own a 03 cummins and it got 16.9 mpg which seemed ok as it was 250hp and a 4 speed auto and way better than my ford early 70's 4x4's with big block gas engines then I bought a 4'' from turbo exhaust a cold air intake and was getting around 24mpg then I chipped it with a quadzilla 4 stage and hit 29.9 mpg and this truck weights 8200 #'s That was a 200 mile trip on I/5 gas station to gas station .Now I run a diablosport power puck 100hp and a diablosport trinity t1000 and have yet to check my gains but love the power of just the puck and seems I'm about mid 20's mpg running local quick trips. Truck is stock height running a set of 285/70/17 toyos and I believe the gears are 3.73 .Before you say hell no try spending time and money and see what your diesel can do as when I did some basics to the wifes TDI jetta she was at 53 MPG and way more power
Nice I got a 2000 4Runner (3.4 liter ) lifted 5 inches on 285/70/17s ! (33s) and I average 17 mpg all day ! And I got 4.10 gears not bad for a gasser huh ?
A diesel driver myself I must admit when I drive my civic to work I don't pay no attention to which pump I park at. Maybe I'll consider next time. We'll c
