D4 SDV6 Engine Oil

[rapserv]

Hi all ... wanting to try a new engine oil to suit my 2013 SDV6 and wondering if anyone is using Nulon Apex+ in 5W-40 Full Synthetic?

The VIN on my vehicle tells me that I DON'T have a DPF and after a lot of searching around and through specs .. I'm interested in trying this newer Nulon oil.

I have been using Nulon and Penrite in the past in a 5W-30 but want to move to a 40 grade due to the higher temps here in Western Australia.

Conversely .. can anyone see any problems in using this oil?

Nup. I now use Penrite 5w40 full synthetic. I changed from Penrite 5w30 once the engine had done 150,000kms. Like you, I don't have a DPF. I have no knowledge of Nulon so can't comment on that. But I do change the oil and filter every 6 months or 10,000km or thereabouts.

OK .. thanks.
I've been doing changes at 8-10,000Km too.
Are you using their straight synthetic 5w-40 .. 'HPR 5' or 'Enviro+' in the Penrite?

HPR 5

Enviro + works as well. You need to check the label on each if it meets thr Ford oil specification as stated in your vehicles handbook. If it doesn't, find one that does. Both Penrite HPR5 and Enviro + do meet the spec. I ran the car on '+' without issues. A quality engine flush is suggested if changing brands, and also gets a lot of sludge out.

[rapserv]

My manual specifies Ford WSS-M2C934-B which is an ACEA C1 oil ... neither of these oils meet that spec.
When you change the viscosity .. to 40 .. I suppose that spec goes out the window ... so what specification should one now be looking for?
The oil I selected .. Nulon Apex+ is actually rated as A3/B4 which from what I can see now is a mid SAP's oil .. and how important this is I don't know!
I note that the HPR 5 at least has the same A3/B4 rating as the Nulon but the API is different .. SP compared to SN/CF respectively.
Unless you're in the automotive game .. the whole thing is very confusing.

Switched to 5w40 about 30k kms ago
Now on 185k
FWIW…and maybe pure coincidence/ luck / other factors…vehicle is not “using” as much oil
On the 5w30..by service time (10k)..vehicle had dropped about 1/2 on the electronic oil reading.
On this oil..no movement
Again, many other factors may be in play, but engine is running well on the 5w40.
I’m happy

When you guys say HPR5 .. do you mean HPR5 or HPR Diesel 5?
Two different spec oils and one FULL synth the other Semi-Synth.

Full Synthetic

API SP is the latest Petrol Engine Spec - SN is the previous generation spec and CF is a fairly old Diesel oil spec now - Current is CK-4 from memory. But with API specifications, anything starting with S = Spark ignition, C=Combustion ignition.
I would avoid using a pure API SP in a diesel engine as they have lower detergent levels to deal with soot particles(particularly calcium). This is to enable them to deal with low speed pre ignition better in direct injection petrol engine.

I currently have Castrol Edge A3/B4 5W40 in my 4.4 TDV8 and intended using Penrite HPR 5 5W40 next time. However maybe Penrite Diesel 5 5W40 would be better even though it's semi-synthetic, but possibly will need shorter changes than 10K kms. I have a digital pressure display so I can tell when the oil starts to thin.

HPR5.
I changed to that approx 60,000 klms ago (I'd have to check my oil results to confirm), now on 212,000k.
I get the oil analysed at every change and noticed a slight improvement in wear metals as a result, eg, Chromium dropped from 5ppm to 3ppm.
I change oil/filter every 7-8,000 klms and use Wynns Professional engine oil additive.

Today I changed from Edge A3/B4 5W40 to Penrite HPR5 5W40 in my 4.4 TDV8 L322. Hot idle pressure was 12 psi with Magnatec A5 5W30 after 10K kms and the same with new Magnatec A5 5W30 Stop-Start and again with Edge A3/B4 5W40 both when new and after 12K kms, but Penrite HPR5 5W40 hot idle is alternating between 14 and 15 psi. I'm not sure if the extra hot idle pressure is good although at 100 kph an extra couple of psi above the usual 14-15 would provide a better comfort factor. Edge kinematic viscosity at 100 deg C is 13.4 nominal and HPR5 14.4 nominal. I changed looking for better stay in grade when working hard so I suppose higher idle pressure shouldn't be unexpected. I'll keep an eye on cold pressures and how quickly it drops.

[Graeme]

Now hot idle is 13 psi so I'm happy with that. Must not have been properly hot yesterday.

HPR5 , NOT HPR Diesel 5.

I've been using it for roughly 50,000 klms having switched from the Penrite 5W30 full synthetic.
My oil analysis results have improved, eg, chromium, copper, iron etc all slightly lower ppm.

I’ve been on it for around 100k km [emoji1360]
