I just got home for the holidays and ordered this for my vehicle.
Couple observations.
My 3800 Series II GM engine has not seen Petroleum oil since it left the Canada assembly line.
Ever since it has been run on Royal Purple or Mobil 1 30 weight grades.
And yes a little noisy too
Well since i decided to add the AutoRX for the 1st time i wanted to use a "premium" petroleum oil.
After reading all the positive posts about diesel fleet oils such as Delvac1300, Delvac1, Delo, Rotella, i figured this may be wise to compliment auto-RX advanced solvency properties
Well 150miles after the oil change what do you know
The 3800 is now whispery quiet!!!! As in the days it was still factory dino that is. Hmmm....is this some kind of divine indication that I should switch to a 40weight or even DINO in the future??
My Auto-RX motive was to "prep" the engine through 2 cycles for a Redline changeover.
The quieting of my engine by the "heavy?? 15W40 Delvac" raising some questions i think.
