Oil , Gear Oil, and ATF fluid reccomendations
 

I would like to hear from the die hard DIY guys on the forum and see what your choice of motor oil, gear, oil, and atf fluid is.....

Motor Oil
Mobil One Synthetic Extended 15,0000
Dexron VI ATF
debating between Royal Purple Gear Oil and Mobil One Synthetic Gear Oil....the stealer wanted $33 a bottle for GM brand gear oil.

What are your recommendations?

Been using Mobil 1. Just bought a case of castrol syn for next time...

Have not touched any other fluids yet.

The 3.5 and truck has been great. Never burned or dripped a drop of any fluids!
