First thing I did was deactivate the active field management by buying a Diablo Sprint tuner. Get your V8 back and run some e85 you'll definitely notice a difference.

I just got turned on to E85 for my 14’ Silverado and your video confirmed that I’m an E85 match 🤙🏽🤙🏽🤙🏽🤙🏽 Needless to say, I’m in California and gas here is $4.65 a gal And as of today because your video I now pay $2.65 a gal Winner Winner Chicken Dinner Thanks a bunch bud!

[@pedepablo1638]

How did it go. I'm also in California and planning on switching as soon as my gas tank empties.

[@clostheman6562]

@@pedepablo1638 What’s bud, make the move.. I’ve had my truck almost 2 years and if I would’ve known then it would’ve been sweet but now is the time… Truck feels great with E85 and honestly it drives a little nicer but you will loose 2-3 miles per gallon but I believe it’s a fair exchange for a $2 difference per gallon 🤙🏽🤙🏽🤙🏽🤙🏽

Awesome!

@@clostheman6562Late comment! but hows E85 been? i got an 18 Silverado 5.3 Flexfuel, wondering if E85 will be more reliable than running normal 87? i mainly want to go with what will be better for the engine in the longer run! i heard E85 cleans your engine and is suppose to be better for its health but i also heard the opposite lmao

[@Jose-ew6hj]

@@REDDELECTRICI have a 2015 fbo on e85 and e85 is definitely worth it. Makes it even better when you start messing with the motor performance wise

I’m in NC running a 2016 Silverado 2500HD on e85. It’s about 30% cheaper than 87 and it’s available everywhere here. Power and mileage are decent

[@belowzero8845]

Great video. All you ever hear is how much fuel economy you lose. Looks like that wasnt the case with you man. Thanks for more interesting content. Keep the vids coming!

[@kipoetter72]

I have a 2015 high country 5.3 I use E-85 eight to nine months out of the year. I live in Nebraska E-85 is readily available here. I don’t run it in winter because it gets too cold here the ethanol makes it very hard to start cold in freezing temperatures. I have tens of thousands of miles running E-85 with my high country with no issues. I average 14 mpg running E-85. Often times our E will test up to 90% ethanol. I prefer it over petroleum products. Exhaust smells better too

[@senjo31]

I agree I could barely smell it

[@chadwagemann3422]

I have a 2007 Silverado 1500, with a 5.3 and been using it in the Summer for years. With some research, I don't prefer it in the bitter cold here in the Dakotas. It is all over in South Dakota and higher octane which I can feel the difference. My salesman said if it is .50 or more cheaper per gallon than 10% ethanol, it is worth using. Usually it is .60 .70 or more cheaper per gallon than 10% here. Great videos! Keep em coming!!

[@patrickopdahl]

I got a 2014 LTZ with the 5.3 flex fuel and e85 definitely adds a decent amount of power. Fuel cost is actually more though. But the power is worth it. And There’s a gas station with e85 about a mile or two from my house. The flex fuel injectors recognizes the higher ethanol and sprays more thus giving you more power and less fuel economy. Worth it.

[@mikewhite3123]

If you're around a big city then e85 is the way to go,but where I live you have to drive 20 miles to get it,but if want the power,it's gonna cost you lol

[@yomuno2511]

Racetrac in my town has it 6 miles away. With E85 I get 16 mpg. With 87 E15 it gets 21 mpg, and runs smoother.

I ran two tanks in my 2013 Z71. Not to happy with gas mileage ! Way less than reg gas. I didn’t notice any more power. Now I have used E15 at Kum & Go and it is way better !! I get better gas mileage than reg and 91

Learned a few things about my high country so far. Also in NWA. I get about 17 mpg highway on a 3.5 lift and 33s

All i run is e85 in my 14 run another tank behind the one that has gas in it! You will tell a big difference!

[@Hugeroost]

David, I have a 14 Z71 LTZ and i'm running a ProCharger. So your saying all i have to do is just fill it up and rock and roll ? of coarse i know it has to be an e85 truck to start with, but what kinda difference will i see, and i could care less about mileage, i dont drive it that much. A full tank of fuel usually lasts about 3 or 4 months at least, appreciate any info....Roost

[@erikmenchaca6319]

First random youtube video thats in the same area as me 😂 nwa ftw

[@crazyboonie9636]

In my 2011 I usually fill up every other week reset mileage then calculate the miles and gallons used to the truck milage meter, its always off by 2 miles or more a gallon to the bad but I got 33's and a 4 inch lift. Usually get 11-12 miles agallon (5.3 4x4 ext cab) not much highway driving due to work is 2.5 miles away tho!

I have a 2018 suburban with flex fuel and u can definitely tell the difference when u fill up and when it gets close to e and it’s sucking that 87 it definitely decreases power

[@njrtvacc]

Im hesitant to run e85 on my 2014 Yukon (5.3) The truck has a bit done to it, but it also has 300k miles. Should I try e85? Are there any downsides other than economy?

[@w3910]

After you fill it with e85 or higher octane your car doesn't change while you driving, You should drive it for some miles so the car notice there are different fuel ,, then turn off the engine and turn it on again to let the engine change the ignition timing and makes some power

[@just_another_gearhead]

That's wrong, it does change on the fly, that's why the sensor is there it reads in real time and will adjust spark and fuel according to ethanol content. I don't know where you got that info but the ecu is always changing fuel and timing, depending on 02 sensor data, knock sensor, mass air flow and manifold absolute pressure data, intake air temperature data, and if you have flex fuel, it changes based on ethanol content as well. It does all of these changes on the fly, as you drive. That's why you can drive up and over a mountain without the car flooding out and dying.

[@w3910]

@@just_another_gearhead maybe you’re right, but i got this info from a tuner and he’s a well known guy and he told me that the car will do little adjustment after start up again .

[@just_another_gearhead]

@@w3910 if it couldn't adjust for ethanol content on the fly, going from gasoline to e85, it would run lean..very quickly. Seeing as the ecu needs to add around 30% more fuel. Numerous times I have left my truck running while filling up from gasoline to e85...no issues, and you can feel to difference. I think your tuner is talking about other brands like Dodge and Ford, I'm not sure if they still do it but those manufacturers use to build a virtual map based off of 02 sensor readings. On those vehicles you do need to shut the car off, their flex system isn't as good as GM's, which uses an actual sensor. Even the aftermarket flex systems typically use OEM GM flex fuel sensors.

[@robertrager2691]

We are at the Come & Go with no raincoats 😆

[@mikewhite3123]

Used to drive a 99 7.3 powerstroke ,and went 460 miles per tank on Chevron diesel,versus 410 miles with shell from 3 different shell stations .. everything I've owned runs better on Chevron and Exxon Mobil than it does with shell...

[@just_another_gearhead]

Ok, so I have an e85 station withing 2 miles of my workplace and I have a company fuel card...so although it takes about 30% more ethanol to make the same thermal efficient as straight gasoline...the benefits are that these pickups (I have a 2014 ltz) respond tremendously to e85...they also run much cooler, as in overall heat...alcohol displaces heat. I can really feel the difference when pulling a trailer, yes I eat fuel but my engine doesn't struggle and stays cool...it also has the advantage of more power by advancing the ignition timing and cam timing (I have a vvt).BUT the cons of e85 8s that if you don't have a good clean airfilter and good sparkplugs you can run the risk of washing your rings out and inevitably washing your bearings out as well and maybe even ruining the lifters. Just stay smart with e85 and do your maintenance and you'll be able to reap the benefits of a good fuel to optimize your engine....also, think about adding some upper cylinder lubricant adder to your fuel every other fill up or so.

[@justingonzalez9950]

Are conversion kits the same as factory

[@just_another_gearhead]

@@justingonzalez9950 most conversion kits use factory hardware...at least in the GM world they do. Need a bigger fuel pump, bigger injectors, and an e85 sensor. Then will need to get the ecu tuned, on a stock vehicle the tune is easy, they just upload a factory tune from am e85 vehicle with the same engine and transmission amd do some minor tweaking here and there to optimize it.

[@graysondenny1950]

you will get more power with true E85 because that was really e70 having a 70% ethanol content

[@aldochevy]

Great content brother! I also have a 2014 Chevy 5.3,I didn’t notice much of a power increase either but got slightly better fuel economy.I’m from Illinois so E85 is pretty easy to come by, I also read that E85 helps with carbon on the intake valves.

[@couchrider6228]

Ethanol burns much hotter than gas probably will burn carbon deposits off valves.

[@matthewvarnam4302]

It burns slower than gasoline it also burns cooler than gasoline.

[@anthonymacneil2279]

Great video, no E85 in Nova Scotia Canada. My High Country 6.2L uses Premium and cost alot more than it does in US. $1.20 a Litre and that's low was $1.40 a few months ago would cost to fill at quarter tank close to $100

[@stevenstrawn5009]

For my 2015 GMC double cab 4.3 v6 base model put 20 in Denali wheels all terrian tires so it doesn't look like a work truck no more. On regular 87 i average around 20 mpg or sometimes little better or worse, when i first tried e85 i had about a eighth of a tank so put 10 gallons of e85 didn't notice to much then once it was almost completely empty filled all the way on e85 then i noticed the power gain but yes it 30% cheaper but you lose the same in mpg 30% i averaged between 14 and 16 mpg with e85 and im pretty easy on the peddle driver.

[@themaximusone]

they have more if you add 1/4 of reg gas and then fill up 3/4 of E85 it will last a week i promise

[@SlingSalsa]

Cheaper by the mile but twice as many fillups, not to be used with a cheap oil and certainly needs fuel additive. Also if you went to a colder plug you might want to get back to the stock heatrange or you will be pissing fuel away(moreso than normal).

[@161995alex]

2014 and newer Chevy trucks have a flex fuel sensor in the fuel line so the computer knows the ethical content as it passes through the fuel line.

[@MrTHARP6]

I know just where you were. Got 19 z71 I’m about to make the swap to 85 I think. Have a modded gt mustang about to make the switch as well.

[@cassp3r23]

So I dnt got to tune or add anything to run e85

[@greyhairedmountainbiker116]

problem is it takes a while for the sensor to reacr to change in ethanol content and eventually you get problems running rich or lean (DTCs too) because tge sensor screws up.... mine thinks I have 30% when in reality it's 10%. F the E85 nice video though. LOL
