Thanks All

Napa Gold #57011, don't let anyone talk bad about them if you get the current filter the design has been corrected, they used to be pleated paper that caused low oil pressure. I use synthetic 5W40 Rotella in the engine but any good 10W30 or 15W40 also works fine, if you think the engine has a lot of gunk/sludge in it i.e. never overhauled or worked really hard you may want to use non-detergent SAE 30. Universal hy-tran fluid in the entire tranny and hydraulics.
