Bull 34 #1 Posted May 25, 2021 Hello Everyone, I am going to be changing my engine & transmission oil soon on my 417A and I was looking for recommendations. I have read 30W Rotella for the engine but the only one I see is diesel rated. Is that okay to use? For the transmission the manual states 10/30 or 10/40 but I was wondering what brand and grade is most used. As always thanks. Bull Share this post Link to post Share on other sites
Maxwell-8 4,367 #2 Posted May 25, 2021 Diesel oil is just fine, if not better in my eyes. Diesel-oil is a better oil, because it can handle higher pressures. For the tranny, I am gone sit back and listen what the others have to say. 2 Share this post Link to post Share on other sites
gwest_ca-(File Mod) 11,472 #3 Posted May 25, 2021 The diesel rating on the bottle will be Cx something. The C is for compression = diesel engine There should also be a Sx rating if approved. The S is for spark = gasoline engine Wheel Horse published Lubrication Charts. There is a note in the manual that states the recommendations are up to date and may differ from the info originally in the manuals.
