Mobil Delvac vs. Delo

[merc123]

I had to swap from Delo to Delvac because the local Wal-Mart ran out of Delvac. It was only $1 more per gallon jug so I threw it in. What a big difference. The truck runs a whole lot smoother and you don't have the metallic clacking from the injectors as much. It really quieted it down compared to the Delo.

I may run this next time I change my oil, or Rotella, or Schaeffer's. My E99 isn't liking the new LE Delo since I ran out of my stockpile of the great old formula.

I run it and my truck hasn't spit it out yet!

I started with Rotella but went to Delo for price.
