Delo 400 Engine Oil

Hi All,
  Costco is selling Delo 400 LE 15w 40 engine oil. Does anyone here use this oil. Will this be compatible with my  1997 Cummins M-11? The LE has me questioning this oil.
Thanks for any info,
Raymond

Cummins C8.3 engines of that vintage always came with Delo 400 from the Foretravel factory. It's the only brand that my Cummins has ever used.

I used Delo for years and always top off the oil as required.  I remember the first time I switched to Rotella T and discovered that I did not have to add oil between changes.  I never looked back!

I am a creature of habit, used Rotella in by big truck, use Rotella in our FT.

BTW, Forrest's Cummins 8.3 325 hp does not consume any oil between changes.  Delo 400 15W40 is also used in the hydraulics and the genset.
