Mobil 1 Turbo Diesel Truck 5W-40.

Look into Shell Rotella @ WalMart

I would suggest that you go with single grade 30W Rotella T from Shell. That would be my choice over 10W30 or the horrid 10W40 oil that some manufacturers don't want used in their engines for any reason. My second choice would be Shell's Rotella T 15W40. Rotella is formulated for diesel engines and is the #1 choice by many large fleet owners.

Another excellent diesel oil is Delo by Texaco and it can be had in either 15W40 or single grade 30W.

Tom: How many Hours on the Kubota ? My Neighbor runs Synthetic Rotella T in his and has since new over 8 yrs . I myself have used 15W-40 Rotella T in my F-250 Navistar Diesel since new and have over 350,000 K and does not burn a drop . If your Hrs are not to severe I would opt for Full Syn.

OK, I had heard of Rotella.

I bought the mower with 500 hours. It now has 550.
It came from a golf course that had 2 Lastec ZTRs + a 12' Lastec 3pt hitch mower (Wide Area Mower). So the ZTRs were only used for trimming. I paid what remained on the bank lease.

I guess it is time to get some Rotella.

Thanks!

Tom : Barely Broken in Dude , go with the 15w-40 Full Synthetic Rotella T you won't regret it ! Enjoy the New Mower :)
