I've run Delvac Super 1300 out to 30,000 mile drain intervals with about 40% idle time on my buses. The best I've ever got out of Rotella is 21,000 miles and then the total base number (TBN) starts to drop. Rotella has a 10.6 base number right out of the jug - - Delvac 1300 has 10.5 At 30,000 miles, Delvac 1300 will drop into the high 9's. At 20,000 miles Rotella drop's into the high 8's. A 1.5 to 2.0 drop in TBN means its time to change.
Rotella diesel oil is like Penzoil automotive oil... It sells really good due to marketing, it is not bad oil, but it is not the oil of choice for most professional Fleet Managers looking to extend drain intervals in a tough operating environment. With a fleet that turns 100 million miles per year, Delvac Super 1300 saves me 1429 oil changes per year ($285,714 @ $200 per drain part+labor) because the TBN number holds up longer than Rotella.
IMHO - I prefer Mobil Delvac Super 1300 over Rotella for two reasons ....... 1) I've spent 10,000's of $$$$ on oil analyses to know 2) I've got a 1,000 gallon bulk tank sitting at the shop where my office is located.

As bhildret, NUTNDUN and olcowhand have stated Shell Rotella 15W40 is the oil to use and is the most popular oil Case LGT owners use upon direction from Ingersoll dealers.

Think you will learn over time it pays to follow MFG. recommendations. I have a Case 1835B skid steer and it also calls for 15W/40 diesel oil along with a TCH anti-foaming additive. Some of the metals in the Hydro-static pump and motors will not get the correct lubrication with a "Tractor Hydraulic" oils. It is a 1985 and had 1 motor put in it due to a broken output shaft. (POs Abuse)
Any Case/IH dealer will tell you this when you ask for oil for that model.
It is probably not a good idea to my lubricate recommendation with out all the information. So people my follow an incorrect recommendation and have a very expensive failure.

also this stuff looks and smells more like motor oil then anything else. its not red like tranny fluid. but its different.
You might as well taste it too. :puke2: You are advising an improper oil for the OP's GT based on looks & smell. That doesn't fly here!

I'll spend around $30,000 of my companies money by the end of this year on oil analysis testing various 15W40 motor oils. I thought the results of that testing would be a nice thing to share on this forum, with my 2nd post, since very few guys can actually afford that kind of information.
I wasn't aware "Shell Rotella 15W40 is the oil to use and is the most popular oil Case LGT owners use upon direction from Ingersoll dealers". Sorry if I have attacked a "sacred cow" in the form of the accepted thoughts surrounding Rotella on this forum, but I do have about 3,300 oil tests results sitting in a filing cabinet across the room, as I type this reply, that says something different about Rotella. I've got $22,000,000 worth of engines to maintain at the moment that use 15W40 motor oil and I can't afford to be wrong about this subject, or just go by what someone else tells me.
I've shared what I know, which I hope is the spirit of this forum. You can either consider what I've said or stick with what makes you comfortable. There are much better products on the market than Rotella..... My experience (and $30,000 worth of test results) has shown me Modil Delvac Super 1300 is one of them. Take this information and use it, or stick with "the most popular oil Case LGT owners use upon direction from Ingersoll dealers". The choice is yours.

I will say that your posts sound more like a Mobil oil dealer rather than someone who hobbies in garden tractors????
