I have a B2410 with 400 hrs. Last year I changed oil and used Kubota Oil. Is there a oil that is less expensive that will work without harming the engine, I was thinking maybe Rotella 15w40? Thanks
Your post was a wee bit humorous. Kubota does not refine oil.
Of course Rotella would be fine. 15w-40 if you like it thick, 5w-40 synthetic if you like quick flow, or split the difference with Rotella semi-synthetic.
