Changes to Pennzoil Ultra Platinum

[jroyk]

I have a hard time listening to this guy, but he’s a tribologist and pretty smart. Sounds like the war has caused some degradation of PUP.

Yep changed the formula and another reason to use another better oil..

You can get the key points of the video by pressing the 'ask' button, then 'summarize the video'. I do that a lot now instead of watching hours of filler in videos to figure out what they are talking about.

@Octanewide Good am Jeff. I’ve always used the Pennzoil in the HC but Mobil 1 in everything else. What do you use in your HC? What about the rest of you guys?

Hey Tony, I use Amsoil or Mobil 1 (I use to work for Exxon/Mobil).
I recently witnessed a tear down of a Ford Ecoboost that needed timing stuff that had over a 100k on the engine whos whole life was on Amsoil and the inside of the engine looked brand new.

I’ve been using PUP. I may switch to M1 ESP or Amsoil. ESP meets Porsche A40, which is about as tough a certification there is. I’d run HPL Supercar if it was a little easier to buy.

I had run amsoil until this year. I put a built shortblock in my car last year and noticed some build up in the oil pan. My friend Tim that runs an 8 second mustang on e85 noticed the build up also using Driven full synthetic oil. Talking with other racers he switched to driven GP-1 last year and when he took the pan off at the end of the season he didn't have the build up, looked new. So this year I'm running the GP-1.

Now if I was not running e85 I would still be using Amsoil 0-40

I started using Amsoil on my 2013 Mustang once it hit 1000 miles. At 5k I put a blower on it. I pulled the engine around 40k miles to put better rods and pistons in it. The shop that did it said the engine looked brand new. So that really sold me on the oil but now running e85 it may not be the best choice for me

I just watched this video, I was going to post about it

Does GP-1 have 0w40?

 

[Unholy707]

What do you mean by build up in the oil pan, what did it look like? When I had my pan off I had a little

 

[Unholy707]

What this guy didn't mention though was the SRT branded oil. There are still manufacturers of the base oil in the US. Maybe the SRT oil still uses the old base oil?

 

[vortecd]

Does GP-1 have 0w40?

nope. I use their 10-40. Not much of a difference. I think we can get hung up on oil and think the wrong weight will ruin the engine. My 13 Mustang took 5-20 but when I put the blower on it I went to 10-30. So for 35k miles I had the wrong oil in it and it looked fine inside

Kinda like thick oil build up.

This was Tim's post

Got a few minutes on the gray area today. This year we switched to Driven Racing Oil GP1 15-40. The pan speaks for itself. No e85 funk, no ring material couple chunks of rtv from when we changed the cams.
In the past we used FR50 and it always had mud on the bottom. Not bad but always some. This was 80 runs 1500 street miles with 1 oil change.
Plus the gp1 is cheaper.

Like sludge almost? What color was it? The stuff in the bottom of my pan I chalk up to break in oil moisture, it was almost like sand. Wasn't metal that I could tell. Very little of it, but it was settled on the bottom of the pan. Dozens of mid/low 9s track passes since discovery and engine runs like a sewing machine

 

[Unholy707]

Yep, that's exactly what was in mine - like a mud, nothing but SRT 0-w40 pup for its entire life changed religiously at 3k miles or less by me. Since racing it gets a change after every outing. Car has around 60k miles

Edit. Make that Mobil1 FS, not ESP.

Their Supercar might be a good pick, too.

All these choices...(and opinions)...now I'm confused
