I run Ursa Super Heavy Duty oil in my Kubota which I buy by the case from the distributor. The last purchase of 2 cases was a couple of years ago and it was never exactly cheap but man, I got a little sticker shock when I had to get another case this week. It's up to $60 for 3 one-gallon jugs! Seems a little steep, don't it? Is all motor oil up that much?
