Pennzoil Ultra vs. Mobil 1: MY OPINION!!!
In another thread on Pennzoil Ultra and engine noise, I posted that I had a ticking from our 392 engine. I changed the oil in it yesterday and decided to use the last of the Mobil 1 0W40 I had leftover for my '08. From the initial start up after the change, I noticed that the ticking was greatly reduced if not gone. However, I didn't want to jump to a conclusion without more "data", in this case, more miles. Today, with the sunny, 55F weather here, my wife and I went for a ride; in fact, a 97 mile drive. During this drive I purposely accelerated heavy and normal, all the while listening for the tick. I have to say, if there was any tick, it was so slight that a normal conversation or regular volume music easily drowned it out. Now, I am not suggesting that this tick is caused by the Pennzoil Ultra, but I would say that the Mobil 1 is masking the tick better.
I wanted to share my experience with our engine tick and using Mobil 1 vs. Pennzoil Ultra. As most things in life, each engine is different and therefore your results could vary. ALSO, there are many oils that others use here, and those could produce similar, if not better results
