Re: Mobil Delvac or rotella t better
Never tried it, but Delvac is supposed to be on par with Rotella (Delvac 1300 versus Rotella T, or Delvac 1 versus Rotella T synthetic.) Locally, Delvac costs more than Rotella.
I've been running Rotella T synthetic with good results. I picked up some Amsoil MCF (at a decent price) for the next oil change to compare to the Rotella T synthetic.
I think consistent oil / filter changes of a non-energy conserving oil probably out way most of the differences in the oil you use.
