Hey guys tried looking but i didn't find a one stop shop post. Do we have a page that lists every single fluid/part that needs to be replaced after xx miles??? Thanks.

Oil - 3000 to 15000 miles, depends on the oil you use

Auto trans - every 30,000

Differentials - every 30,000

Transfer case - every 30,000

Dexron - says 5 years or 100,000 miles.......I do mine every 30,000

DOT3 - 3 years or 30,000 miles

Power Steering - I do every 30,000

Those intervals are what I do. My truck is a 2004 that I have had since new. I'm still on the original motor, transmission, rear end....never a problem with my G80, original radiator, original power steering pump and the brakes I redid for bigger and better.

I also get 27-30 mpg in a CC 3.5, auto and 3.42

So take what I say for what its worth......but its working for me

I'm using Royal Purple in the motor, rear dif and power steering

Everything else is normal off the shelf stuff from AutoZone and Pep Boys

Thanks man I appreciate the info, I'm avg. 20-21 mpg though I have the 3.73 not sure if thats the big difference but 25+ would be great. I have an 05' also original owner I'm right under 85k, I somehow lost my maintenance records so I'm gonna bust it all out at tax return.
