Default Best Diesel Oil???

Hey guys, just have a quick question. Looking for some opinions on a good brand of diesel oil to run. My local mechanic said to NOT run Rotella, because it does not have an anti-foam additive in it. He recomends running Texaco Ursa. I have since switched to Ursa, but cannot find a place to buy it except through him. Here in SE Iowa, we have Rotella EVERYWHERE, but not too much else that compares in price. Any suggestions?? Anyone else heard anything bad about Rotella? All opinions are appriciated!

I didnt see John Deere 15w40 plus 50 in the above posts. I run that along with many other people here and have no reasons to try anything else. my 2 cents

Same here...

It seems a little thicker than most oils....actually cut down on the oil psi fluctuation
