Could someone tell me what hyd. oil I could use for my 140G, my local supplier handles Mobil brand oils. Thanks.
You could use a product from either the Mobil DTE 10 or DTE 20 range, ISO 32 viscosity in both cases. Alternatively if the supplier has it in stock Mobiltrans HD 10W would also work. Although it's a powertrain spec oil it will work just fine in hydraulic systems. Don't you have an O&M Manual for the grader..? $46 gets you a pdf download of a genuine Cat manual.
Thanks Nige.... located manuals, & got the correct oil !
