I've been thinking about doing this on my 2015 Denali. Has anybody else done the cab spoiler mod and if so do you have pictures and what are your thoughts? I'm on the fence for installing it for a few reasons one is my truck is only a two-wheel drive and it kind of looks something that a four-wheel drive should have from what I've seen from a distance. But then at the same time does it actually help with fuel mileage wind resistance and stuff like that? I do have the trifold tonneau cover installed on might as well. And I'm also looking at wanting to install a cowl hood scoop or Hood and was just looking at thoughts or suggestions. My truck is already metallic so it's that nice awkward color LOL. I do want to mention this has been one of the best trucks I've ever owned however I have noticed with treacherous rain that we have endured the past 3 weeks I finally started seeing water dripping in from the third brake light and then a mysterious water leak on the passenger side between the glove box and kit panel happened one time and I haven't seen it since. I did check my rain gutters and drain tubes for the sunroof I did check the windshield and found nothing coming in from those points. Do you other things are my folding mirrors are now not wanting to close or open together, both of my seat bottoms no longer heat up and on the remote start it seems like there is an excessive grind or rattle sound when it starts up but also is the motors running it seems like the ticking is louder than usual.. I know this is a lot of questions but I know this website is awesome for information so all help would be greatly appreciated.

      I never understood the hate for the column shifter. The console shifter just gets in the way, takes up prime cargo space and in my wife's Jeep, the dog constantly bumps the console shifter into neutral!    Best choice ever to just make it a column shifter across the lineup and be done with it.    (Bonus: Makes swapping from a 5 seater to a six seater far easier)

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

      I had an 88 K1500 with a 5.7 that had those symptoms, I know totally different, it ended up being the ECM. Once you get the fuel system fixed if it still runs lousy you may want to investigate that. it didn't set any codes, stalled ,ran rough at times etc

      Trading 7.3 (Godzilla) for G.M.C gas

      Congratulations Isttype, on your gmc. Really like my 2024 2500hd sle doublecab now with 85,500 miles.  I checked the oil today at 4800 miles since last oil change and barely reading on the stick.  I don't care if GM says it's Acceptable adding a quart every 2000 miles because that is 100% BS, It is not a 1966 Harley Shovelhead! Sounds like it's setting up a future failure like I had with my 1500 6.2l. Other than oil consumption problems, I really like the 6.6l gas and 10 speed is really nice.  Towed a light 4000 pound trailer last week and averaged 14 mpg.  I was pretty impressive that a 7300 pound gas truck did 14mpg towing, Later-

      Long Term Cold Cycle Limited Testing   Back to the 1990's and XOM's million mile test. Since then there have been others and there will be more. Schaeffer's, AMSOIL to name two. Of these Schaeffer's is the stand alone which I will explain in a bit later.    http://papers.sae.org/600190/:   http://papers.sae.org/850215/:   Up to 75% of  engine wear occurs on cold starts. These two links (above) provide the technical reasons for engine wear. In a nut shell, and by a large margin, cylinder wear is what takes out most motors and even with a pre-oiling system that part of the engine is dry enough on cold starts and cold warm up to pierce Stribeck.   So when you put a motor, or a car, on a dyno for a million miles stopping only for oil changes, (yes fuel is uninterrupted) or break down maintenance, you are depriving the test of the most important part of it's wear cycle. Yes a million is then a pretty easy walk even for a mineral oil under those conditions.    How about cleanliness during the long test cycles? Same thing. Varnishes that stick rings and insulate parts are laid down by repetitive 'heat cycles'. It's the cool down the precipitates the varnishes. These long runs also hinder acidic attack caused by cold start richness and less than optimal cold start ring sealing. They hinder water formation and enhance breathing of the crankcase; the petri dish of acid formation, the first step in sludge formation, amalgamation and precipitation. These motors are also monitored and controlled for water and oil temperatures to within the "normal operating range".      https://www.swri.org/sites/default/files/sequence-iiih-test.pdf Note the test sequence in some boutique oils literature for testing, API IIIH, is not the standard used for the ILSAC G7 testing. Does that mean it is irrelevant? No, not as used. As used as a 'visual guide' it makes it's point. The G7 weighted piston deposit minimum is lower.      Back to Schaeffer's. That was a cyclical test of an engine in fleet service and not a dyno mule and if you saw the video it was not mirror clean but wear was low.    There are oils like BioSyn and other 'Renewable" source oils that taught cleanliness and have proven themselves in fleet testing. Havoline an other example.    The newest ILSAC G-7 test prioritize cleanliness, LSPI mitigation and fuel economy OVER WEAR. In comparison Porsche C30 Specification Verses ILSAC G-7 Specification below:      Some will balk that this graph isn't apples to apples and I will challenge that in that this graph represent the SPECIFICATION and not the any One Oil Performance.   It is absolutely possible to minimize wear, maximize cleanliness and mitigate LSPI etc., It just isn't cheap and currently I see none that are not walking toward profit over performance.
