Are there any studies out there that compare Chevron's Delo 400 to Mobile's
Delvac diesel oils?
I usually run Delo, but in my last discussion about synthetic oils, someone
mention Delvac. I am about to change my oil. I decided to stay with Delo
or Delvac. Which is a better quality, or are they basically the same.
Thanks in advance.
