Also factor in where you live! In extreme temperatures, having the right fluid is crucial. What do others think about fluid behavior in different climates?

I find it slightly amusing that we discuss fluid like it’s a fine wine! As long as it’s suitable and affordable, we should be good!

Great advice, Kristen! I might just go for that. It’s always better to play it safe with these big engines.

I’ve experienced fluid leaks in my Duramax, usually around the hose connections. It’s crucial to check for cracks or loose fittings regularly to prevent bigger issues.
