Pennzoil can hardly be compared to Red Line or AMSOIL. Pennzoil is the Budweiser of motor oil. And there is nothing wrong with that, some folk like Budweiser... However, AMSOIL and RedLine use superior ingredients and chemistries. I doubt that your experience will be similar.However, I'm hesitant to call this a success until I reach the 2000 mile mark as it took that long for my truck not to like the PUP 5w30/0w40 mix I did years ago.
AMSOIL SS is their best motor oil. On b@@bs there was someone comparing AMSOIL SS 0W-40 to PUP SRT 0W-40. And he was doing it using UOAs. Of course, everyone agreed that AMSOIL is overpriced and that PUP is cheaper and did marginally "better" on the UOA. His engine? 6.4L HEMI. The hypocrisy bogles the mind because the dogma on b@@bs is that you can't use UOAs to infer wear, which is something I happen to agree with. Folks who've been there for a long time also agree. That's because the "wear metals" are particles that the oil interacted with and disolved into a liquid. That's why Red Line shows higher wear on UOAs, when in fact it lowers wear.Funny you should mention this, I've been VERY impressed with SS 0w40. So far.
I have about 1000 miles on this run, about 680 of this is towing my camper through the mountains of western MA and NY. I have no ticking on either side of the motor. When I tried the SN+ formula SS 5w30 it was ticking by 500 miles of just driving, no towing. So this is very encouraging.

I was particularily impressed when I put Red Line 5W-30 in my mom's 2017 3.3L Santa Fe, and it made the start-up timing chain rattle completely dissapear after I got it up to temperature and drove it around for 10 minutes. The rattle is due to a worn tensioner that Hyundai refuses to address, and her vehicle has 26K miles on the clock. Debris accumulates and prevents it from moving back and forth fast enough. Well, Red Line took care of than. I am switching all our vehicles to Red Line. Considering what we currently pay for some of the worse gasoline on the planet, the cost of Red Line is a drop in the bucket.
Something interesting: the additive packages and friction modifiers for Valvoline MaxLife, AMSOIL ATL (blue cap), and RedLine D6 are identical. The only difference are the base oils, with Red Line and AMSOIL being higher quality.
I also just got my order from Elite Race Fab delivered, all Red Line fluids for the Durango.
