    6.2 or Diesel?

    I think the 3.0 does have a 100k warranty… as opposed to 60k on the gassers.

    6.2 or Diesel?

    Well.. a brand new yukon.. and that oil and engine has 25 hrs on it… if you look at the picture you can see quite a bit of metal out of the sump.. really not happy a new motor looks that way. As far as this motor goes… i do not think cleanless is where it was when i had an ‘18 5.3 during...

    6.2 or Diesel?

    Well.. i was careful.. however.. below is the first 25 hr drain. Quite a bit in there.. not really happy. I have built a few engines.. you must be clean.. otherwise you are wasting time and effort. The second drain at 50 hrs.. was what i expected. Decent. I think everybody needs to get a quick...

    Considering a 24-25 Suburban. Which engine is most reliable?

    I will say… the 5.3 has been around a while.. my guess is that clean-up of the blocks is now poor.. and the tooling to do the block/heads has seen better days. First figure is the 5.3 filter and what magnetic contents there are.. figure two is the first drain of my ‘24 yukon.. right block is the...

    Is New Engine Break In Procedure Still Necessary?

    I recommend changing oil and filter at 25 hrs or so on the engine. You can see what drained out on my first oil change at 25 hrs… nothing better than a pic to look at.. zoom up on it and you can what came out…

    Sad Day - Moving on to a Truck

    I just bought ‘24 yukon and a ‘25 sierra.. the yukon has a 5.3 and i changed oil at 25 hrs… the same thing on the sierra with a 3.0l All things being equal.. maybe the tooling on the 5.3 is about used up? Left pic is the 5.3 with a magnet run over the filter… right side is the 3.0. The duramax...

    6.2 or Diesel?

    I am not a oil burner fan.. each one i have in the past has always had some problem.. that was enough for me. However.. things have changed… below are two magnets that i have used to test my 5.3 in my 24 yukon and my 3.0 in a ‘25 SLT gmc truck.. also.. the oil drain bucket i used on the 5.3 was...

    Best place to buy extended warranty

    I also did Todd for a ‘24 yukon… i think it was $1450 for 72/72.. i just wanted a little more for the 5.3 in it.. i did $250 deductable.. an engine and tranny are my main concerns..

    2025 Diesel orders opened

    I just traded my ‘22 lariat in on a slt with a 3.0…. I could get 24 mpg with the ford… i started with coolant leaks on the eco… and just had enough. Coast is clear on the 3.0…

    2025 Diesel orders opened

    I have a 2024 yukon with a 5.3… but i did just get a duramax 2025 slt… i have had many oil burners.. not really a fan. However.. i have changed my mind… if you get one that does most of what you want, i would. They great driving and do very well mpg. Pete

    Engine choice for new Yukon XL Denali (best reliability for next 3 years)

    I have a ‘24 with a 5.3 which i did due to lots of problems with the 6.2. I have had four 5.3s and never had any problem with them.. i also have a ‘25 sierra with a 3 liter in it. I think it is noisy like most diesels are and gets 28 mpg. I think the first version with cast al pistons is much...

    Tahoe Retirement Vehicle

    I just bought a ‘24 yukon. I did a 72/72 warranty for $1472, $250 deduct.. i am 63.. but i do not want a crash taking me out.. yukons are pretty safe. Little cars.. none of my wives emergency room workers are in small cars. They usually do suburbans..
