    Am I Burning Oil?

    My latest oil change on my 2021 Yukon Denali with 95,000 miles only rendered me roughly 5500 miles until it was bone dry. However, the oil life remaining indicator said I still had 30% oil life. Am I burning oil? From the research I can gather, I should get closer to 7000 miles per oil change.

    2012 Yukon xl 4x4 eating antifreeze?

    Let me start off with the fact that she runs perfectly. She's got the 5.3, no hiccups, no codes, no rough idle, live stream on the scanner shows no reds, etc. I have a generic scanner, but it's able to do almost everything a dealer scanner can do. She's got 275k miles on her and she purrs like...

    Question about AFM

    I drive a 2014 Tahoe with 175,000 miles on it. It was making a weird rattling noise when it was in V4 mode around 25 miles an hour so I got the plug-in disabler off Amazon and it stopped the noise and it keeps the vehicle and V8 mode so it can’t go into V4 mode to make the noise. Anyway...

    2021 GMC Yukon Denali Oil Burn

    I've got a 2021 GMC Yukon Denali with 85,000 miles and just had a notification pop up on dash about low oil. Oil Life Gauge has me at 38% life remainging still. Checked the dip-stick and was bone dry. Any thoughts on why this could be burning almost 40% oil? Put 2 quarts in it to get me by until...

    Pickup tube question on 2007 GMC Yukon Denali 6.2

    So I have the common dreaded low oil pressure. I replaced the pickup tube ring and still have low oil pressure so I'm about to tackle the oil pump. Does the pickup tube mount directly to the oil pump? Asking because I would like to see and feel the fitment again of that O ring. I have seen...

    Question about oil pressure 2014 Tahoe.

    About a year ago I was getting low oil pressure. Maybe 17-18 when warmed up and idling in park. Changed oil and filter and it went up and I didn’t think of it after that. Now I have taken it on some road trips. I use the AFM disabler as well. I was at a stop light and had my foot on the brake...

    So this isn’t good, right?

    Crawling around for the first real time under the Yuke just now and found a LOT of fluid. Oil level is perfect. Haven’t checked trans yet.

    Oil life question

  10. iboughtatahoe23

    Can’t tell if my oil to full. Seems to go past the hashmarks. No symptoms of to-full oil though

    I drained the old oil all the way and put 6 quarts of fresh oil in my 2014 Tahoe.

    Did my first oil change ever on my Tahoe. It was messy.

    I think I did ok. I drained the oil, installed the new and lubricated filter, added 5 quarts, ran it for a minute ( I heard lifters and stuff for a sec until oil reached everything is that normal) shut it off, checked stick, was on not level surface because I live on a residential street and...

    Low oil? ‘14 Tahoe 166k

    Does my oil look low? It seems to reach the 4th whole and stops. I was on maybe a 2-4° grade/slope in my driveway. I’m also concerned cause there’s a whole lawsuit for excessive oil consumption in these models. I’m about close to 2k since my last oil change

    OW20 IN HOT CLIMATE

    So I have a GMC Yukon 2016 5.3 V8. The recommended oil is 0w20 which has been used in my car up till now 70,000 km. I live in the Middle-east where the temperature in summer goes up to 50C AND even in winter it stays in the 30s. I was reading about oil grades and it says 0W20 is good for cold...

    Oil issue

    Hey guys I got a 2005 LS Tahoe 5.3, the oil was changed I’d say close to a month ago and I remember looking under it and saw a little oil droplet just where the drain plug was about a week later after I changed it. I looked under it yesterday and I see this. How is the oil making its way through...

    Hello TY Forum, while I wait for the parts to repair my transmission I decided to take advantage of my free time looking for a big oil leak in my Tahoe (2WD - street use only).

    2011 Tahoe White/Blue Smoke on Startup, Dealer Says New Engine

    Noticed within the past few weeks when we would start the truck cold in the garage, we'd get a puff of white smoke, minor blue hue, but very white. It billows for about 10-15 seconds, then goes away. The truck runs perfectly fine. No temperature issues or overheating. I performed a combustion...

    Yukon oil leak near back of oil pan

    Hello. I was doing an oil change today on my 2008 Yukon XL Denali AWD and noticed oil around the oil pan. I wiped everything down and ran the engine for a few minutes. The oil collects around the bolt marked with the red circle in the photos. I noticed the oil pan bolts were a little loose so...

    Oil not showing full on dipstick until 9 qts. were put in

    Hi all, I've got a 2004 Tahoe LT with the 5.3L. Recently I took it in for an oil change at a jiffy lube or something similar (I know I know, but I needed it done quick). They gave me the car back and were asking me if I had the 5.3 in it and if I had an aftermarket oil pan or something. I told...
