dasbulliwagen Posted November 13, 2009 Share Posted November 13, 2009 Manyof the newer Jeeps (newer being a relative term) call for 80/90 unless it will see regular towing or is equipped with a towing package in which case 75/140 synth is reccomended.

Carl'sMJ Posted November 14, 2009 Share Posted November 14, 2009 80w-90 here... Don't forget your friction modifier for your limited-slip, posi, or locker if you have one. :yes: Link to comment Share on other sites More sharing options...
pilotblake Posted November 14, 2009 Share Posted November 14, 2009 friction modifier? Link to comment Share on other sites More sharing options...
Pete M Posted November 14, 2009 Share Posted November 14, 2009 friction modifier? It's required with clutch-type limited slip diffs. Otherwise you'll burn up the clutches in no time. Link to comment Share on other sites More sharing options...

Pete M Posted November 14, 2009 Share Posted November 14, 2009 The aussie locker is a locker, not a limited slip and has no clutches to worry about. See their website if there's anything specific they recommend. Link to comment Share on other sites More sharing options...
