Oil, oil, and more oil?

[ericchiesa]

3 Questions please... my L260s main gear case calls for 18 qts of #80 gear oil! Will 80w 90 work? Much easier to find and also cheaper. Engine oil just says 30w does that mean diesel 30w or standard 30w? My other issue is the hydraulic tank calls for something called turbine oil #140! My Napa guy has never even heard of #140! Any help would be appreciated trying to change out all fluids. You guys are awesome!! Thanks for all your help in advance. E

My personal thoughts
Diesel oil, 15w/40, 10w-30, 30, or whatever is on the shelf. Your location/temps, 15w40, stock standard diesel mineral oil.
80/90 will work, it's a bit heavier, 75/90 would also work, turbine 140, IIRC it's somewhere around 80/90. Personally I'd probably go with 75/90 in everything except engine. Kubota UDT would also be a option.

North Idaho Wolfman, whitetiger, others may chime in and give you something different, that's ok, everybody does it a little differently.

On my L185 it say something similar for transmission (which is also 3 point hydraulic reservoir). I switched to UDT then to universal tractor fluid and have had no problems.

Engine oil must be diesel rated as has been stated already.

You can use UDT or UDT equivalent in everything except the engine.
Engine 15w40, 5w30, or 5W40 will all work.
