I actually contacted HSS about this a few years ago. Their SDS didn’t list PAO even though it has a CAS # and the Pour Point also suggested there was little to no PAO in their “100% PAO” oils. The response I got was very convoluted and did not answer my questions. I also posted this same...

The irony of calling an oil “modern” when it’s CI-4 rated. Likely super defense is a rebranding of Delvac MX

I had a 2009 Jetta TDI, it was my first new car. I installed a magnetic drain plug at 30K miles. It always had high iron wear in UOA and visible metal chunks on the magnet. I assumed it was from the BSM or oil pump drive key. Never had any diesel that shed ferrous metals like that car. It was...

“We don’t take kindly to oil additives ‘round here.” Some of us real diesel oil in our TDIs. That’s synthetic CK-4 10w30 and 5w40. I use 15w40 in my PD. You need to deal with the BSM module if it hasn’t been deleted. They are problematic in CBEA engines.

I use Amalgamated TDR-FL year round in all my diesels since 2017. It's a summer formula. It doesn't get below 30F and even that is very rare here in N. California. I have never had any issues with emissions systems or fuel systems using this additive. It does everything and does it very well...

I wanted to take advantage of this promo but Pennzoil Ultra Platinum doesn’t have many offerings and nothing that can be used in a diesel like a3b4. Kinda disappointing IMO.

Not sure exactly but CI-4+ is a good place to be. The other P66 lubes use Moly or Titanium which show up. Not expecting them to use something organic in a full SAPS oil, doesn’t seem to make sense.

Ash is 1.38%. No idea about base oils, SDS isn’t helpful. https://www.phillips66lubricants.com/product/victory-diesel-aviation-oil-10w-40/

No soot % or fuel included. Fell out of grade as well, its now a 5w30 could be due to FD. Soot is a major factor in wear. Synthetic HDEOs have more dispersants and handle soot better while reducing wear. I'm sure you would get better analysis with an HDEO 5w40 that meets CK-4 but it won't have...

That’s a UFI made filter. They make the fuel filters for my canyon diesel. I didn’t know they made stuff in China.

Not many diesels use a wet belt. The last VW TDI EA288 engine had one as well as VVT. This was in the 2015 model and last year to be imported. There was no change in oil specifications from the 2009-2015 VW TDI engines when the 2015s were released with the wet belt. This would imply that the...

PS doesn’t use a catalyst in their white or silver bottle formula AFAIK. The PS flush product has aromatic hydrocarbons and solvents according to the SDS. Additives are a mystery as there are ingredients which my be omitted from the SDS as a trade secret but residuals show up in the oil...

Good news. I wish we could still get Mobil SDE here in California. Everything is renewable, B20 or a blend unless you go to a rural station some have real diesel #2. You can also try an additive that has combustion catalyst like MMT or Ferrous Picrate. I can say from experience that MMT does...

All the Mahle branded VW filters are made in Austria that I have recieved from multiple vendors. I stopped buying Mann after I got a fuel filter made in CZ that was clearly not made to the same standard as the German version.

I have a 2.8 Duramax. My last soot was 1% at 12K miles. https://bobistheoilguy.com/forums/threads/2017-2-8-duramax-mobil-delvac-1-esp-5w40-cj-4-w-rli-booster-pak_12k-oci.403106/ Before I got the forced ECM recall by GM in 2022, this engine burned clean with very low soot. Like 0.1-0.2% It...
