  1. Hi everyone, I’m new to this forum and I just want to get a good idea of how many miles everyone’s getting out of there 14-18 5.3’s / 6L80 combos and what type of maintenance y’all are doing to get there. I have 90,****** now on my 2016. I follow my service schedule to a T. Trans fluid and filter every 22,500 and engine oil every 4000. What’s everyone else do to get there trucks up to high mileage
  2. Curious to know who in this forum has the highest mileage truck. Just took delievery of my new 2018 truck with the 5.3 V8 and 6 speed tranny and wondering how long I should expect it to last? Coming from a Toyota with about 350k kms I have set the bar pretty high haha. Feel free to post the year of your truck with the # of miles and what repairs/replacements you have done to date. Trying to get a little thread going about mileage and what people have been able to get. Since this is a 2014 forum I'm not expecting massive numbers, but I know some of my friends with Rams that have had engines and transmissions break down at 50k-80k kms (moment of silence for Ram owners) Ford seems to be doing a bit better in terms of major issues. If there's already a thread regarding this issue please redirect me to that one
  3. Morning, I am trying to make an educated decision concerning buying a new truck. I am looking at a 2500-3500 Silverado 2017-18... I was sold on the 6.6 Diesel but to be honest the price is holding me back. I have found a few deals and this months incentives are fabulous. BUT that is not the question. The question is I'd like to hear from owners who have the 6.0 Gas version and the 6.6 Diesel. How do your trucks preform? Mainly the Gas because I have no doubt the Diesel is a Beast. But with a 10k higher price.... and about .40c a gallon more for fuel plus Def.... and Maint. What type of mileage are you Gas owners getting under towing conditions? I will be towing about 13k loaded. Even though not near as powerful does the 6.0 give good overall performance to your needs? Longevity? Thanks I really appreciate actual owners thoughts and experiences. DS Keith M SW Ohio
  4. I just rolled over 36,000 miles and could not be happier with my mileage. I'm not a light foot, I tow a 6,000lb trailer at least 7 times.a year up in the mountains of Idaho, and.... and hot damn that's what! I never thought a 6.2 beast would do so well.
  5. Okay, Algore and company please leave the thread now and tune in to the most recent global warming propaganda station, as offensive stuff will follow. If you have a problem with your cat converters clogging, and you end up gutting them (even temporarily to avoid engine damage), you may note some horrible gas mileage. My truck... a 1996 K3500, 4 door, 8 foot bed, with 5.7 Vortec engine, 4L80e transmission. My mileage went to 7.5 mph (yes, literally) after opening converters. I had been getting 11 to 12 mpg. Fuel was so rich it would fog you out sitting at the drive thru. :o I got lots of advice from various folks, up to and including that I needed to just "bite the bullet" and replace both cats and o2's or the truck would never get correct fuel mileage. And the guy with the spinner in his ball cap of course points out that opening up the converters is ILLEGAL. (he likes to put that in all caps)... And his name is Ogilvie, regardless of what his forum handle happens to be. But a GM tech who is a friend of mine told me to unplug the rear 2 oxygen sensors and see what happened. That in fact worked *perfectly*... my truck began to run like it used to, and mileage went back to 11 to 12 mph. I do realize there is a way to use anti-fouling spark plug spacers to offset the 02's in the front (maybe?) to create a temperature difference, and get rid of the check engine light. But my front 02's after 22 years don't want to budge. I post this just in case it may help someone out there with the same problem. Dan
  6. I've read articles about best ways to drive to consume less gas including some threads on this forum. My question is: What is the number one thing you noticed you do that has positively impacted your fuel consumption on these 2014+ trucks? The photo below was posted on another blog which astounded me. Yeah it's only the last 25 miles but unless I was driving downhill for 23 of them, I don't think I could come near this. The only information about the photo is that it's a current generation Silverado and the owner was 'hypermiling' with no specifics listed. Needless to say it sparked my interest on the topic.
  7. As the title states, I'm starting to research some lift kit options for an old 2003 Bow-Tie. It's an extended cab stock z71 off road package with brand new BFG 265/75r16 tires. What I'm attempting to get out of this forum is discussion from owners of similar models that have gone this route and can give me some personal experiences. There are many options for lifts, but my preference is to lift no more than 4" and most ideally, just a 2" or 3" lift. I don't really want a leveling kit, but am open to suggestions from all areas. If I were to rank my vehicle knowledge, I would place myself as a 4/10. Possible lift options Zone 2" lift Rough Country Leveling Kit I'd also like an explanation on torsion keys vs suspension lifts (I don't plan on doing a suspension lift) so that I have a better understanding of what to expect to be careful with. I know torsion keys are going to extend the depth of the suspension and cause the shocks to not be able to travel as far, but I'd accept a rougher ride as a sacrifice for running bigger tires and having higher clearance. Here are some pictures of the truck I've bought (no I didn't pay the sticker price). Thanks guys
  8. For the LTZ 5.3 vs 6.2...looking at the 4dr 6.5bed...the mpg it shows on the window seems a little low for using AFM...what are your actual numbers you get? We'll say without towing, and with if ya got it...say you just bought it and went on the freeway for a few hundred miles and AFM was on, theres no way to get 18-20mpg, is there?
  9. Hi guys. Was wondering if anyone had a easy way to keep a check on fuel octane levels? I saw this Russian made device OKTIS-2 http://www.ebay.com/itm/PORTABLE-FUEL-OCTANE-NUMBER-ANALYZER-TESTER-METER-OKTIS-2-NEW-/161886552305 looked like it would be useful for keeping an eye on octane levels and it is cheap (under 100 bones). looks like you just stick it in the tank and then pump some fuel through it, seems rather ingenious but not sure how accurate the thing would be? The reason I am looking is that I recently installed a canned tune from a hand held programmer for premium fuel 91 plus octane in my 16 Denali 6.2 I buy Shell 93 octane and the truck has run great for the first week after that premium fuel tune install but after I filled back up with Shell 93 octane last Thursday the next morning on the way to work I got the "reduced engine power" warning on my dash anytime the engine was over 3000rpm. I suspect that the fuel was BAD from my local Shell station but have no way to prove that...... I went back to stock tune friday afternoon and the issue is gone but now I do not want to use the premium tune without verifying that I am actually getting 91 octane or better fuel. Note: Gas line was busted in AL a couple of weeks back and Middle TN has suffered from spotty shortages of fuel (most notably premium fuel) I suspect that my local Shell had regular fuel loaded into their premium tank. (could have been a mistake) my plan is to run this tank all the way down to just a few gallons and then hopefully have a tester in hand and fill back up with REAL premium 91 plus octane fuel. Anyone got one or have something else that they use?
  10. John Goreham Contributing Writer, GM-Trucks.com 5/23/2016 As a follow up to our story reported last week, GM is now cutting checks to owners of vehicles which had inaccurate mileage information on window stickers. Owners and those who have leased a 2016 Chevy Traverse, GMC Acadia, or Buick Enclave will receive checks from about $450 to $900. The variation has to do with the size of the error (and if the vehicle is front or all-wheel drive). Alternatively, owners may opt instead for a longer bumper to bumper warranty. The window stickers had a 1 or 2 MPG error. Consumer Reports says the mistake may also include older models. Look for an update if they become part of this reimbursement. Here at GM-Trucks.com owners of these large crossovers have noted poor mileage in the past.
  11. Hi All, This is my first post so I am sorry if these questions are "stupid". So I finally went back to owning a truck (had a F150 for years and traded it for a commuter car and couldn't deal without the size anymore so I decided to finally get a GMC!), just hit 500 miles on my 2014 All Terrain with 5.3 motor Crew Cab 4x4 and wanted to see if any one can shed some light on some concerns I had so far. 1 - I have been doing about 50/50 city and highway driving and I will say I drive like a slow poke grandpa, always easy off the line and average about 65 mph on the highway. So I have been getting around 15 mpg... is this normal? I did read a few topics of people average 20 mpg who drive harsher than me but also have a couple thousand miles on their motors so is this a "as the motor breaks in the mileage gets better" issue? 2 - So as I said, I just hit 500 miles and I know the dealership told me I get free oil changes every time the computer says its time but shouldn't I be changing my oil the first 500-1000 miles to get out all the break-in shavings? Or is this just something we used to do with older vehicles? 3 - My last truck with only 2 wheel drive and this Sierra has a the 2 rear and 4 auto settings (the other 4 wheel options as well) and wants to know, should I keep it in 2 wheel rear or 4 auto? Someone was explaining to me that they are the same exact thing except when the front wheels need traction they will engage when needed? Thanks a lot guys! I'm stoked to finally join the GMC family and so far I have gotten nothing but head turns and compliments on the 2014 Sierra so I'm hoping the truck does end up getting better MPG. -Drew
