What do you guys think is the better diesel oil? Shell Rotella or Mobil Delvac?

Also, I've heard a lot of discussion about how Base III oils are not "true" synthetics. What are your guys' thoughts?

I run Rotella in all my trucks and its never done me wrong so i dont see any reason to switch to Delvac. Plus around here Delvac is pretty pricy compared to Rotella so everyone runs Rotella. The synthetics? Well i havent heard anything on them really and i have never run em in my trucks so i couldnt tell ya. But I'll ask some diesel heads around town to see what they have heard and report back.

I run 5W-40 Shell Rotella Synthetic in my truck, my wife's 2004 Dakota gasser and my garden tractor with a 25hp Kohler. Never a moments problem.

If you click on this PDF link, and go to page 3, it has the latest standards and explanation for diesel oils.

I'd try to stay away from the LE - low ash oils if I could. It ranks pretty low when compaired to the "regular" diesel oils.

Here is another PDF link. http://www.turbodieselregister.com/TDR57_Oil.pdf While there is a lot of oil info here, page 4 has a comparison chart of all the available oils on the market. All the "ho-hum" oils at the bottom are the new LE oils.

oh yeah, there is one thing about rotella that just changed april 1st, they have a new formula out that is without zinc in it which engine buidlers are concerned about using in brand new motors without an additive.  used to, my local high po engine shop used rotella 10w40 to break the motors in simply because zinc acts as a scuff protector and protects the bearings better, but now that it lacks it, who knows

WELL I HAVE USED ALL THE REGULAR OILS, EXCEPT CASTROL. I HAVE TRIED THE WALMART SUPER TECH OIL, and MY TRUCK KEEPS RUNNING!!! I'VE CHANGE THE OIL AT 4,000 MILES 99% OF THE TIME, BUT ONCE I WENT 10,000 MILES, and MY TRUCK KEEPS RUNNING, I NOW HAVE 131,235 MILES and STILL RUNNING. I WILL SAVE MY MONEY and KEEP USING REGULAR OIL, THE ONE THATS ON SALE!!!!

Please help this very confused fan of Lubrication Engineers, Inc. products.I followed your recommended link and thank you for that as I'm always eager to read test results whenever I can. Your post mentioned that all of the so-called " ho-hum oils " , the last four , were all the new " le oils ". Is it me or is " le " used in reference to something I'm un-aware of ? I saw four oils produced by the companies whose names are on the labels. What makes you want to stay away from " le "? Have you had bad experiences ? Did your engine get noisy or did your fuel economy go up or did the oil analysis tell you there was un-acceptable wear metals and premature additive depletion? Please help, if "le " is truly a bad product I need to know so I can get something else.
