Oil change: 6qts then I’ll just add 1/2qt at 3K miles… will drain 5qts, @6500miles oil change (with18%-20% oil life). Didn’t affect battery, it’s over 3yrs now.initial reviewInstalled on 2008 avalanche at 130K miles. After installing this, car/truck has a smoother and more responsive acceleration When pressing gas. Eliminates some knocking sound/vibrations when slowing down or at stop. After 15 gas refills It didn’t really affects my 16-16.5 mpg with lots of idle on this cold northeast weather , still see how it does on summer (I usually get 17-18mpg). I purchased the extension wire with switch (picture) Incase It gets the battery drained but So far It didn’t drain battery yet after 4 days in the cold So I kept switch ON. I have yet to see how it affects oil consumption.It’s a great product that turns OFF afm... I wish I had known this earlier

That I didn’t buy this years ago.
I plugged it in when truck was off and it worked immediately. I also used remote start, plugged it in then turned the key to “on” and it worked. No more 4 cyl!
Added bonus: the transmission feels a lot better. It used to lunge when coming to a stop or making a turn- that’s gone now for some reason. It also holds on to gears a bit longer and maybe it’s in my heads but I swear it shifts smoother.
Excellent product.

5.0 out of 5 stars TRY THIS IF YOUR HAVING SERVICE STABLITRACK/TRACTION CONTROL/MISFIRES ON GM TRUCKS!!!!!!!!!!!
Reviewed in the United States on December 18, 2016
Verified Purchase
I drive a 2011 Silverado with about 125,000 miles on it. Around 100,000 miles my oil pressure sensor went out and after I replaced the sensor, the truck started throwing codes for multiple random misfires (eventually narrowed down to just cylinder 5 misfire) and service stablitrack and service traction control messages, also rough idle/shifting. After taking it to the shop (they were clueless even though GM knows what's going on) and replacing just about everything that could be replaced (plugs, wires, coils, cleaned throttle body) all to no avail, and after hours of reading chevy forums, I finally found a promising solution: apparently, the active fuel management started going out (probably won't throw a specific code for the AFM) and this lead to these problems. Instead of paying $400+ for an engine tuner that would allow me to turn off the AFM, this bad boy is half the price and 100 times easier than tuning the engine. Literally, all you do is plug it into the OBD port and drive. That simple. After the light turned solid, I drove for about 8 miles and, to my astonishment, no codes were thrown! I cleared the codes so the check would turn off and after a day of extremely cold weather and a little less than 100 miles, still no more problems! This bad boy is a God send! I get more response, more power, and, in my opinion, better gas mileage. It's like a new truck. After dealing with this for over a year and a half I was ready to trade it in but not anymore!

4.0 out of 5 stars Problem Solved
Reviewed in the United States on November 12, 2015

I installed on a 2010 Yukon Denali with 6.2 L and cylinder deactivation two weeks ago. The lifters had developed the habit of sticking in the compressed position and when they released a loud rattle would ensue from the top of the engine. The lifters would ultimately fail and would stay in the closed position. I replaced all 16 lifters in the motor last January. In October I had another lifter fail. Days after replacing this lifter the rattle returned. My goal at this point was to disable the entire deactivation system. My mechanic advised that my only option was to replace the existing lifters with non-deactivating lifters (another $2500). Not wanting to do this I started researching ways to disable the system through the computer. I found the Range Technology AFT Disabler Device. Immediately upon installation all evidence of lifter failure stopped. Installation was simple and the results were immediate. I have not experienced any unintended consequences with the computer but will be watching for this. For now, I am extremely satisfied with the product and it's performance.

January 27, 2016 - update. I must reset the device on a three week interval. Otherwise the computer attempts to override the device. I am now in the habit of resetting each Sunday morning on the way to church. This is a slight in convenience but better than major engine surgery.

5.0 out of 5 stars This device works. My mileage actually improved a bit, someone at GM should explain that one to me.
Reviewed in the United States on September 21, 2020
Verified Purchase
This unit really works. My new 2018 Silverado 1500 ("e" model) was running well before I plugged it in the OBDII socket, but I wanted the option of disabling this V8-V4 mode because of what had happened to my friend's 2011 Sierra 1500 (excessive oil consumption between scheduled oil changes due to worn rings on an otherwise meticulously maintained truck. This was traced to a lack of proper lubrication in V4 mode, an issue supposedly fixed since in the newer models). I just couln't afford to take any chances at having to go through an engine disassembly so soon in my truck's life. I mean, how long have they been messing with V8s? They should have left these engines alone instead of messing with cylinders 1, 4, 6, and 7. Since I do mostly highway trips, my mileage has actually improved, not by much, but it shouldn't have if you believe the GM hype. You really have to wonder why all this V8-V4 complexity was added to a perfectly good V8 if as, in my case, my mileage improved!!! The ONLY thing I miss at times (easily fixed by shutting down the truck and just unplugging it from the OBDII socket) is some engine compression braking in hills from the V4 mode. It helped me maintain a set cruise speed going down some hills with a light 2000 pound trailer load, and the fact that the engine no longer shuts off at stops or red lights (the "e" model has the Lithium battery pack and induction motor to spool up the engine under these conditions but it won't do any of that while this particular unit is plugged in). Other than that, I have the V8 I expected now, the mileage is fine and hopefully I won't have issues with failing parts in cylinders 1,4,6 and 7. The added complexities of these otherwise old V8's should be a cause for concern. They use a special camshaft ground differently just for cylinders 1,4,6 and 7, they have a higher-volume oil pump, and a pressure relief valve to handle the incessant oil/computer controlled operations of the intake and exhaust valves in these 4 cylinders and this device just stops all this from happening without reprogramming anything. I could be wrong of course, but I think the pressure relief valve should have no issues handling the changes for the life of the engine. The rest is literally put to sleep while this device is plugged in.
If you want to take your truck in for maintenance, say while it is still under warranty, just remove it before going into the stealer. They will never know. Hopefully I'll never have to go in for expensive repairs due to failures with cylinders 1,4,6 and 7. Make sure you get this device with the latest firmware as it is now totally stealthy to Onstar's big brother monthly reporting. Range Technology has done its homework. I don't work for them, I'm just a happy customer and would recommend this to anyone just wanting back the V8 truck they thought they bought.

Range works as it states and keeps my 2017 Silverado High Country in 8 100% of the time. Bought it as I have a nice MRBP exhaust system but didn't like the low tone when in 4v. Does it change the gas milage, that can be debated, as the liters doesn't drop to 0 when going down a grade. Or when slowing down, I truly think it now reads correctly and will drop to 3 liters per KLM. One thing for warning is if you park the your truck for a few days , pull the unit out as I feel it'll slow drain the battery.

Reason for 4 star as the unit plugs in upside down and if Range Engineer's did there home work. The unit would plug in right side up for aesthetics.
