Looks like M1 EP 5w30 formulation has possibly changed.
- Thread starter FTTSHO
- Start date
Last but not least, I would like to add that I do not think the formulations have changed, but what ExxonMobil chooses to report or not have changed. I don't think they are required to report PAO and/or GTL. Don't consider an MSDS as a recipe—it is not.
Again, check the four-digit formulation number on the date stamp for the actual formulation—not to be confused with the four-digit label numbers next to the QR codes, the latter of which identify the front and back labels, not the actual formulation.

Well, people want PAO, here is PAO.So in a thread of M1 EP, why would you recommend it when it’s not a thing.
Current M1 0W40 FS on the shelf hasPAO, GTL and Ester.
Bcs. It is designed for MUCH tougher demands.
If you saw the UOAs for the Red Line High-Performance, you wouldn't want to try it. The Red Line High-Performance is only meant for racing, not for regular driving. It could strip away the lead in your bearings if you use it regularly.
If you want PAO and POE, there is the Amsoil Signature Series and certain Ravenol oils. Mobil 1 Extended Performance 0W-16 and 0W-20 used to be mostly PAO and AN, but I'm not sure now.
It was always a good oil but maybe needed improvement. Anyone have any info or thoughts?
I agree. It's not very good for mainstream modern vehicles in my opinon based on UOAs an ppls opinions on here. It's great in ultra high performance vehicles I'm sure that never see high mis etc
Why would Red Line High Performance strip away the lead in the bearings?
Redline is VERY popular on the track. But for everyday driving, I would skip engine oils. I use their D4 in my BMW stick, and it is excellent stuff.
Even on the track, if it is once a month thing, Mobil1 0W40, Castrol 0W40, Pennzoil 5W40 etc. would do the trick.
I had excellent results with Castrol 0W40 and Mobil1 0W40 on track.
Never heard that either..
Reaching ever higher eh JJ?
Uh, yes, I know. I was running it previously because of the moly but switched to Mobil for the PAO. Now that the Mobil doesn't have it anymore, I am going back to the Valvoline. I think you assumed I thought the Valvoline had PAO. My point was that without Mobil having PAO I see no reason to not continue with the Valvoline I was using before.
I don't know. It's probably lead corrosion due to a formulation issue. It has a lot of POE, and perhaps that along with an improperly matched additive package is causing the problem.
RedLine 10w-30 5k mi; Honda S2000 40k mi
This is my first UOA with this car. It's got 40,000 miles on it and compression tests 230 on all 4 cylinders, it comes from the factory at 240. The oil tested, Redline 10w-30, had 5,000 miles on it with an OEM filter. The UOA is showing high copper and lead counts in a ratio of nearly 2/1...

Corvette UA0 with Redline 5w30: High Lead
Car is a 2006 Corvette Z06. I bought it from an old geezer (older than me!). So it wasn't abused. Been putting Redline 5w30 in every 4k miles. Car is a daily driver with 2 Auto Cross days (car would be driven harder on a canyon cruise) Car uses about 1/3 of a guart every oil change which is...

High Lead Redline 5W40 thoughts? Ty
This is my first oil interval using Redline oil for my 1994 Montero 3.5 DOHC. Used Fram Ultra 9688. When I changed the oil there were no ferrous particles on the Gold oil plug, for the first time ever. Castrol Magnatec 5W30 was used prior to this. I'm original owner. Montero is garage kept...

I asked them that a while back. Some type of corrosion but could be inconsequential. It's been discussed a lot on here. Tbn drops off quickly too. I still think it's more of a racing/track oil than daily driver. Oddly enough it does really well in certain motors where Tbn does not drop and Pb is low. never understood why.

Interesting. The reason I picked up EP for the next change on my Accord was due to PAO. It takes 0w20 though so hopefully I'm in the clear, but who knows really. All the name brands have solid formulas but we are here to split hairs. Thus the reason I went EP! If they take out the PAO I may be inclined to switch brands.
Valvoline full syn has PAO ? In what ratio..where did you hear /read this? Just curious. Thanks.
What's an extreme cold climate anymore? Northern Canada!? I'm in Western Ohio we had a 2.5mo winter at best (I love the seasons!) an a looong Spring. Using any good brand full synthetic @ a reasonable OCI will yield good results.
There's a ton of real good full syn oils out there. I think a reasonable OCI is more important here than a change of oil brands. Both Mobil 1 & Valvoline are very good. I've used Pennzoil Ultra Platinum for yrs in both my TGDI vehicles w/ great success! The oil analysis on that oil is excellent too. Maybe try that? It's a step up from Valvoline & Mobil 1 silver bottle (possibly EP too) by most so called "oil experts" opinions. Amsoil Signature Series picks PUP as its main competitor in its marketing even. I'm not a fan of the boutique oils for 99% daily drivers out there. Most the majors beat those in the important tests anyhow.
Rapid TBN drop will cause lead corrosion. Lead corrosion is not inconsequential, as it results in bearing wear.
TBN, TAN, Ca, Mg, base-oil quality, oil life
I revisited this old Chevron Oronite reference about TBN retention and Ca vs. Mg detergents. It studies oil life and wear in diesel engines. TBN measures the amount of acid-neutralizing detergents (Ca- or Mg-based) in the oil and TAN measures the amount of acid in the oil. Here is what I...

TBN retention: Are we missing the point?—Chevron Oronite
Therefore, this sounds like a formulation issue—a detergent and/or an antioxidant improperly matched to the base oil.
