What Oil?

[Texasgreen]

Does anybody know what brand of engine oil Montana/LG puts in the crankcase from the factory? I just did my 50 hour oil change on my 4940C. I went with Shell lubricants ROTELLA® T. I have used this brand of oil in my larger plow tractors for years and I have had good results.

I've got a 4540, and did my 50 hour service early this summer. I don't know what comes from the factory, but my dealer recommended Shell Rotella T, and that's what I used. No complaints from the tractor so far...
