Fluids

[LonArcvarden]

Im sure there's 100 threads here about all sorts of fluids, but rather than scavenging for information that leaves me questioning, I'd like to address them all here.

What is everyone using for Engine Oil, Coolant, Transmission Fluid, Differential Oil, Fuel Additives, and anything else? And why? Who gets the best deals from where? What makes one fluid/brand better than another? If Im missing any other obvious questions, please tell me!

MOPAR, because it's easiest. One stop shop, at the dealer, getting manufacturer recommended fluids. Change them at the recommended intervals and you don't need much more.

I’ve had good luck sticking with factory spec fluids and swapping them a little earlier than the manual suggests, especially for diffs and coolant. I started doing that after seeing how much smoother things ran on my bikes after using stuff I originally grabbed alongside some honda spare parts I ordered. For the Jeep, brand hasn’t mattered as much as sticking to the right weight and changing everything on a steady schedule.
