Maintenance to early?!? Am I crazy?!?

[TylerRST]

What is everyone's thoughts about driveline fluid maintenance, ( intervals and product ) I have always done the differentials, transfer case and transmission fluids every 30,000 miles on all my trucks, I also just use the GM fluid knowing I change it often enough and who should know there vehicles better then GM right. I currently own a 2020 6.2 1500 and do drive a bit aggressive ( love the power of that 6.2) also tow 6000 lbs a few times a month. I've been a firm believer in fresh fluid is good cheap insurance. I'd like to hear everyone's opinion of my rights and wrongs. Thanks!

Been doing the same for decades.  My Yukon was like a bucking bronco on the road until all the fluids were changed and she settles down and drove so much smoother.  My interval is intended to be 36K miles.

Won’t hurt.

You would think so, right? Dexos1, dexos1gen2 and the ever 'coming soon' dexos1gen3 were trotted out at evolutions of improvement when in fact they proved to be a string of repeated failures on a multitude of engineering levels. OEM's have decided to use the buying public as their R & D lab and don't mind paying the lawsuit cost as a form of research investment. Not only into what the machine needs or will take but what the public is willing to endure. They know what the issues are. They know what the solutions are. They just don't see any of that as profitable. When something fails miserably they take a second bite at that apple then simply replace it. Think the entire line of Ecotec I4 motors. Major law suit. A promise the 2015 and newer would not suffer the same issues do to engineering and lubrication improvements, more law suits...dumped the motor.  The 3.6 V6, a cow they are still milking whose cam chains and ring packs are the focus of the Gen3 Dexos oil specs. Which they will again fail at. 

 

First car I ever bought myself, a l...o...n...g time ago, taught me that the right foot is directly connected to the wallet. How it is used and operated  and the environment it lives in has more to do with life length and any other single factor alone. 

 

Second is lubrication maintenance. Keep it full, keep it filtered, keep it cool, keep it changed. Even a bad fluid, as you know, will do the job under conditions ideal to it's chemistry.

 

Third is choice of products. The right fluids and the right filters can increase the length of life by multiples IF the first two points are met like drawing ones breath. That is consistency in consistently doing it all. Sadly, something few have the patients to execute or the wisdom to understand.

You're on the same page as me. Regular frequent fluid changes, has served me well.

TylerRST, do you do filter also or just fluid?

I do early change out of all fluids.  Usually within the first 1,000 miles.  The differentials I switch over to AMSOIL and then change them at 100k miles.  The transfer case I do at 50k miles and the transmission. 

 

I did a uses oil analysis on the differential fluid at 100k and it was good and was told to take it out to 120k next time.  I also did the transmission fluid at 100k since I kind of neglected it to that point and turns out it was good as well but I try not to let it get that far along.
