VOA and used oil results HPR5

[3516]

Opinions on oil and the analysis results
Engine is a Common Rail 3.2 Liter 5Cyl Turbo Diesel
Oil is Penrite HPR5, API SN Plus, Acer A3/B4

Had a VOA done last week due to the lab questioning the oil viscosity reported Vs the Manufactures TDS
Results on the sheet attached.
19 June 24 is a VOA and is the batch currently in the engine
22 May 24 oil did 3657 km (2272 Miles) and 7 Months on oil - Oil and filter Changed
4 October 23 oil did 6400 km (3976 Miles) and 12 Months on oil- Oil and filter Changed

Attached are the reports from the 3 samples and the manufactures TDS

Thanks, John

Thanks mate.
You couldn't post the VOA again at a bit higher resolution, some of the numbers are a bit tricky to read.

 

[fantastic]

Looks good & seems like 5w-40 Is working. Longer interval didn't seem to bother this oil much. Although can't see a viscosity on that one but I'll assume it was just fine for the shorter mileage.

Thanks mate.

The forum seems to degrade the resolution after loading. It happens to me all the time. PDF looks stellar but loading it on here is low. OP could zoom in a bit perhaps to make the number bigger at least as a resolution to your request.

I gave zooming in and snipping it a go
The 18 June 24 a the VOA
Other 2 are UOA. Oil changed each time

Thanks for the VOA and UOA side by side. Thanks for zooming in.

I do like Penrite HPR 5, it's a 5W40 full synthetic with Euro ACEA A3/B4, and now it's API SP (yours is SN-Plus) and it has official MB 229.5 approval. Penrite directly link to the MB letter of approval on their website

It's a 40 grade, and J300 says it should have a KV100 viscosity of 12.5 - 16.3 cSt, the Penrite data sheet shows 14.4 cSt, your VOA is 13.8 cSt and your UOA is 12.9 cSt. It's still in grade after use, and Euro 0/5W40's all tend to be at the lower end of J300.

Penrite list zinc at 1240 ppm, you show around 1000 ppm, which is a bit low from the listed figure. But at the same time it's also similar to other Euro 0/5W40s that I have seen analysed. It's also nicely above the the usual 800 ppm Zn for ILSAC fuel economy oils. Zinc (ZDDP) is a good additive as it both reduces metal wear of the engine and acts as an antioxidant to protect the oil for longer oil life. It can damage exhaust cats in an oil burner, but a Euro oil with about 1000 - 1200 ppm seems about right to me.

The Ca & Mg detergent and TBN package is typical of an API SN-Plus / SP oil, to reduce LSPI in TDI petrol/gas engines. A nice dash of moly at 50ppm to reduce friction, and a touch of boron at 80 ppm.

The wear metals Fe, Al, Cu, Pb, Sn, Cr all look under control, no concerns there. The silicon is there in the VOA so it's probably an anti-foaming agent and also of no concern. The oil is doing its job.

This all looks good to me. Thanks for taking the time to test and post.

Thanks for the feedback.

When looking at oxidation and PQ index numbers now I have a base reading what would be numbers to look out for that would be out of normal range ?

How much of a jump in Sodium number would be cause for concern. These engines are known to get ither a EGR leak causing coolant to be burnt in combustion or a oil cooler leaking coolant into oil.

Thanks

I don't know much about Oxidation and PQ index numbers, so I hope someone else can answer that for you.

Coolant usually shows up as Sodium or Potassium, you got a good baseline for these numbers now with this oil, at 1-2ppm. I'm no expert, but when it reached 5ppm it would have my attention, at 10ppm it would have my concern. Maybe someone else can add a bit more detail.
