42K on 2016 GMC SLT 5.3L 8speed...Change oil @10K consumes 200ml....absolutely 100% acceptable another guy on this forum goes 15K and consumes 1/2qt so there you have it.  AFM I like and enjoy my 22.8mpg on HWY's extended trips.  No thanks, keep your ecoboost......

I'm at 124k now. I've changed out the air filter three times, oil changes, tires, and brakes. That's it, and zero problems w/o a catch can. I have new wires and plugs ready to go. Also swapping ou

Do all the high milers still have the AFM enabled?

I still have AFM enabled. My truck is still stock as far as drivetrain is concerned. Stock exhaust, wheels, intake, etc. I did put lowering shackles on it though.

Just hit 120k on my 2015. I plan to write up a little review of the last 2 or so years with the truck. I honestly drive it pretty hard. With the nht package, the 3.73s with the 6spd really pull in my opinion. I drive in M-5 only to keep it out of v4 mode. Anyway this truck either hauls weight or tows daily. I keep up on regular maintenance but this truck has needed no repairs. I just replaced the stock battery a month or so ago. It has new brakes (upgraded them), 3rd set of tires (33s this time), but that's it. Tire shop told me the lower bj was bad so ordered all new Moog uppers, lowers, tie rod ends, and a level kit. The ball joints were all fine. They lied to me to try to get me to let them install it all, along with the leveling kit for some insane price. I let them know in person that they lost my business due to BS'IN me. Anyway, I just received my AAls, New rear extended shocks (stocks are still fine), trans filter/fluids, spark plugs and wires. Going to do all that but like I said, regular maintenance only. I'm very happy with this truck. I'll probably need a new one in 2 years, but I have a goal of 300k problem free miles.

Nice story on your truck. I too hope mine goes 300K  miles. I am guessing you will beat me there though. I add about 140 miles each day I go to work. I believe keeping up with the maintenance is one of the keys to longevity.

Thanks man! You'll get there quick with a 140 mile round trip each day! My commute from home to my office and back is 90 miles, but I'm usually in 4 states each day checking on jobs and meeting with customers all over. A lot of start and stops. The starter still fires up fine, but I do have one on stand-by in my garage as I imagine it'll go soon with the overuse it gets. I do regular oil/fluid changes in everything. Engine, diffs, transfer case, and will be doing the trans again. The trans cooler has never let my temps hit above 194 and I've towed pretty heavily a bunch of times. I drive aggressively, although in a safe manor(to the truck and others) frequently too. Sorry...carrying on again, but I have nothing but great things to share concerning this truck. It's not my first GM truck, just the one I've had the most miles on. The other two, a 04 Colorado (3.5l 5 cylinder @ 90k) and my 07 Sierra (5.3l 4spd with 8" lift and 35s @ 80k) were also flawless when I sold them. I'm a GM fan for sure. I do have my eyes on the new F250/350s though!! We'll see what these 19s produce! Good luck everyone!

Great report! Good to see and I'm with you about these trucks! I get tired of all the Trolls on these type of Forums that get paid to bash a certain item!

Do you have a catch-can?

No catch can. I've thought about getting one, but obviously it's not a problem! I believe in the "drive it like you stole it" methods to keep my vehicles and toys alive. Obviously I'm not slamming gears, smashing the go pedal, but I'm methodical with the way I drive my vehicles. Hard on them? Perhaps, but like I said I do it in a manner that I'm not hurting anything or applying hard/crazy force to them. Hard to explain I guess.

I generally try to trade in my vehicles before they hit 100k miles (160k kms).  I do this to have reasonable value at trade, not because of impeding mechanical doom.  A change is also refreshing and I would not be motivated to trade with-in the same body style unless something catastrophic happened to my current truck or I had a major lottery win!.

I'm the same way with mine! I have a 14 High Country 6.2 with just over 123k miles. No catch can ever. Had the AFM enabled up to 116k miles before putting a black bear tune on it. I drive it hard, borderline abuse it, and have no issues. I plan on doing heads and cam this winter and will do a detailed post to see how everything looks without having a catch can on for all these miles. I have no plans on getting rid of this pickup. So I'm curious on how many miles I get on it before anything major happens, if anything does.

I do this too, easier for people to get a loan on a sub 100k truck than a +100k truck which means we benefit more trading in early before hitting that mark.

      87 down as low as $5.14 here... winning!

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      Progress... sort of.   Intake is disassembled, spider is out, fuel lines removed. Used a torch on the stripped screw with the lower intake off, much easier when I've got the intake sitting on my workbench, I made it talk. Walked right out with a pair of vice grips once it was nice and toasty hot.   New parts are piling up on my service cart waiting to be installed. Distributor, temperature sensor, new gaskets, fuel line kit, themostat, water neck.   My new pickle is I don't want to spend $600 on a replacement spider. I'm not sure IT is bad. I'm probably splitting hairs. Or it's $300 to send mine away and another 3 weeks of the truck just sitting. I have half a mind to assemble everything with the old spider to see if I can get away with just replacing the fuel pressure regulator to be safe. The obvious issue was the gushing high pressure fuel line which will be replaced. Getting to the spider really isn't that hard, and now I know what I'm doing , swapping it would be a breeze should it absolutely need one. Stupid, or smart?   The part that gives me pause is replacing the distributor. Well, it's already out. And I didn't mark it, whoopsie! Engine was at TDC when I removed it, I know that, so upon correct reinstall the metal tip on the rotor should point to the TDC mark on the distributor because that's where it was pointing on the old distributor. Worst case I'm a tooth off and have to re-stab it.   But then, what? I assume the truck will start. It doesn't appear the timing can be set. Here's the problem: These distributors can't be rotated but a degree or two, by design. What I read is Cam ****** needs to be -2 to +2 degrees, ideally at 0 (and checked/set above 1000 rpm). There should be enough wiggle to get that properly set, but checking the reported value is another potential issue. My Actron 9185 scanner says it supports enhanced GM PIDs and Cam ****** is one of them but it's unclear that I'll be able to correctly see it over OBD 1.5. I can see why people end up junking these things with life left in them. They're an absolute nightmare with tweener-year diagnostics/electronics and unobtanium parts.   Fingers crossed it starts and idles nicely. There can be hope, right? I'ma buy a lottery ticket the same day just in case.   Next steps..DO IT. I have not installed an intake before so I've been reading and watching a lot. Some say NO RTV except on china walls, some say DO RTV on water ports but not fuel/air intake. 1/4 or 3/8 bead on China walls? I think my strategy will be, obviously, RTV china walls with overlap on the gasket corners. Chapstick-style RTV the water ports. Leave intake ports dry. The only set of intake gaskets I could find locally are Edelbrock performance gaskets (uh...for an asthmatic 190hp V6? LOL) so we'll see how they do.   #NoToolLeftBehind. It took an hour, but my recovery mission for my deep 10mm socket was successful. It had rolled down the bellhousing and wedged itself between what I think are the fuel lines? I couldn't see it at all, but with a junk antenna I had laying around, I blindly went poking/sweeping for it, heard it clink, raised the truck, and caught a sliver glimpse of chrome with a flashlight way up there in Narnia. I had pushed it farther along the lines holding it captive, but within access of severely improvised tools, poking and cursing at it to finally knock it free to where I could get a fingertip on it to bring it home.    Not much to see.
