Just to compare the Russian Oil Club (ROC) VOA data to the Shell technical Data Sheet (TDS) (Here) for the HX7 10W40 semi-syn.
KV40 Viscosity (cSt)
ROC = 91.99
TDS = 92.1
KV100 (cSt)
ROC = 14.09
TDS = 14.4
I consider that a good match
Repco's monthly retail flyer had 2 pages of oil on special, and GTX 20W-50 of course, so was going to get some for my daughter's Laser...and then noticed the Nulon's. They had 20W-50 high mileage, semi synth, A3/B4 cheaper than GTX ! I went in to get it today (had to order to our branch) and the counter guy said ''Wait until you see what we have Penrite on sale for next week!''
No, no, no, I won't be looking at what they have Penrite on sale for !
Wow a semi-synthetic 20W50 that is A3/B4, that is much better than the old SJ GTX 20W50 that is used to buy. Good work Silk.
I've said it before, but Nulon has really picked up their game recently.
This is probably the stuff
(Link Nulon semi-syn 20W50)
The semi-synthetic (SN & A3/B4) has a TBN of 11 and SA of 1.1%, while the regular Nulon mineral 20W50 has a TBN of only 5.8, SA of 0.8% and is just rated API SJ.
You definitely got the much better stuff for your daughter.
I was wanting it for the Volvo, but got a better deal on the Penrite at the time. It was cheaper than the regular 20W-50 Nulon, so a good deal I think.

No, the semi. With all the different oil pack sizes, you need to calculate cost per litre to see if it's a good deal. Can't compare a 4 litre GTX with a 6 litre Penrite. The Nulon semi comes in a 5 litre, the mineral 20W-50 in a 4 litre, which of course is cheaper, but per litre the A3/B4 was cheaper.

Good to see you back B320I
BTW at Repco till 18 March (tomorrow) they have Penrite Vantage Semi-Synthetic in either 10W40 for 20% Off, or 15W40 for 25% Off.
Both semi-synthetic, both API SN/CF & ACEA A3/B4, and both the big 6L container which helps if you have a larger sump size.
Also 20% off Ryco oil and air filters.

Yeah, nah...too thin for me.
What can you tell me about their 30 SR5 ? They seem to only list it as a lawn mower oil, not any other application. I'd kinda like to see it aimed a little higher, diesels for example. It looks ok from what little I can find on it, they just don't seem to take it seriously.

Truth be told, I've not had any complaints with the Valvoline EngineArmour 15w40 the past 6500km or so its been in use. The oil has turned dark fairly quickly and seemed to be cleaning up some muck under the valve cover from what I can see through the filler hole (I know, such a scientific statement). And it was bought for $18.99/5L or something stupidly cheap like that.
This discussion has me thinking, though. Perhaps 10w40 is a worth a second look?Hi Silk,
I recently spoke to Penrite about this, their Mono Truck SAE30 is a pure Group II oil.
Given this is a pure Group II monograde (not the old manky & waxy Group I stuff) you can expect much better cold flow properties - certainly good enough for you and me even in winter, plus good oxidation stability.
BrocL says it should be very shear stable
The Penrite Small Engine SAE 30 should be much the same, but it doesn't carry the above OEM specs and it has a much lower TBN.
kV40 = 90 cSt
KV100 = 11 cSt
Zinc = 1170 ppm
TBN = 6.5
Looking at similar SAE 30 oils, you can expect a low Noack volatility of about 6 to 8 %. The Mag1 SAE 30 lists it's Noack at a low 6.1%. Here is a VOA of Rotella T1 SAE 30, just out of interest.

I'm very interested in these oils myself, I just need the shops to put them on sale with their regular multigrade PCMOs.

Thanks for that. I only see SAE 30 in the lawnmower section, and they tell you nothing on the bottle, although I'm sure it's all good. I'm using local brewer Aegis Oils for my SAE 30, and it seems pretty well the same as the Penrite Mono Truck you have shown. I might have to give Repco a nudge and see if I can get some.
The Airhead has 30 recommended from zero to 30 degrees, right in my zone, and I'm keen to give it a go. Not often I get out below zero, but those frosty mornings usually turn into a beautiful cloudless day...and in the afternoon I kick myself for wimping out.

20w-50, and anything else outside official grades, used to just have an API rating, and not much info. It's good to see Penrite and Nulon giving these oils an ACEA and manufacturers approvals, even if how they get them is a bit dubious.
My understanding is that ACEA specs are self-certified. I think Penrite have always done a good job and I trust them, but in the old days Valvoline Australia would claim things like A3/B4 and C3 which is just not possible under the modern sequences as they are mutually exclusive when it's comes to stuff like SAPS levels.
However Valvoline have recently pull their socks up and I am less concerned now.
Speaking to Valvoline over the phone a few years ago, they told me DuraBlend (DB) was a better product than EngineArmour (EA) as the DB contained more synthetic and you could push out the OCI for longer. They said DB was a 12 month oil while EA was a 6 month oil. On the bottles (from memory) DB was rated A3/B4 (TBN > 10) while EA was rated A3/B3 (TBN > 8), in general. But Valvoline did some silly labels back them. Their old EA 15W40 spec sheet clearly says TBN of ~ 8.
I recently rang Valvoline and they said they have just upgraded EA to be the same quality as DB. The new EA has increased synthetic content. The bottles are now labeled A3/B4 (TBN > 10) and the new 2017 spec sheet show a correct TBN of ~ 10. So it all seems to line up.
They said DB is now only being sold to garages and workshops for their professional line, while the EA is for the DIY people. But now it's the exact same stuff...guy on the phone stressed that. If you look around big stores, some sell a product called Valvoline DuraMax, I was told this is just DuraBlend done as a special package.
The new EA (A3/B4) is very good, the older EA (A3/B3) more of a basic product. That's my take on multiple Valvoline conversations, and studying their spec sheets a bit too much.
The new EA bottle looks a bit different too, just google EA images and compare to your bottle. Easy to tell apart. Nothing wrong with the old stuff though, I just prefer the new stuff.
I would order them like this for 15W40 semi-synthetic
1. New EA
2. Penrite Vantage
3. Old EA
For 10W40 semi-synthetic I would go the Penrite Vantage first.
Just my 2 cents.
