Did Petronas stop making Selenia 20K?

I've been recently on their main oil page and just noticed that Selenia 20K is not mentioned in their product range ... They offer: K, WR, Star, Abarth, Sport, Racing, Multipower Gas and GOLD SYNTH.

https://www.pli-petronas.com/products/am_selenia.aspx

So my question: did they stop making Selenia 20K?

And another question: 20K had a 10W40 SL/CF rating, whilst GOLD SYNTH now has a SAE 10W-40, API SM/CF, ACEA A3/B3/B4

Confused ...

You can still get it from shop4parts so I'd assume yes, unless it is old stock.

No idea, all my Selenia 20K cans were labeled production date 2012, so not sure, probably old stock. Is GOLD SYNTH a replacement for 20K now, since its a SM/CF oil which is a newer standard than the previous SL/CF ... ?

the acea rating is what matters, from all those you listed. A3/B4 is a very good lubricant for petrol engines and diesels without DPF

A3 is normal these days.

A2 was scrapped

A1 is extremely basic old tech.

Did they change Selenia Gold in some way? Seems a bit weird that an older brand of oil used for Alfa's Boxer engines would have a better API rating than 20K for TS 16V engines.

Am I missing something?

It isn't unusual for the same oil to get re-rated as later ratings come along.
Remember that the last engine 20K was spec'd for will be getting on now.
There were official doc in 2007 that had 5W40 StAR for 1.6/1.8TS engines, so quite understandable to have dropped 20K.
That same doc had 10W60 for the 2.0TS as well as the 2.0JTS. By then, the 2.0TS was only in the 147 and they were selling in very small numbers.
There is no point making an oil that there isn't a big enough demand for.

A3 superseded A2 but A1 is current and not basic old tech. A1 is the category for long drain fuel-efficient oil. It's the European version of SN/GF-5 also with a long drain parameter.

A1 is not long drain.

So would there be any downsides to using lets say Gold instead of 20K? Or should I go for the 5w40 oils?

Not worried about oil consumption or costs, only for the cats on my 1.6 TS. Star 5w40 is a C3 graded oil (supposed to be good for the cat), Gold and 20K aren't.

At the time it was "StAR" not "StAR PE".
The current "Sport" is probably closer to what StAR was at the time.

The current oils on the website are "K PE" and "StAR PE" (both of which are essentially the same spec... but StAR PE just has the Alfa branding).

Obviously you don't need to use Selenia oils at all.

Not quite...

A3 is an oil with a HTHS of at least 3.5 Mpa.s B4 means it allows for the highest amount of ZDDP. Together this means this is the best protecting ACEA spec for passenger cars

A1 is a spec for cars that rarely get up to temp and aren't run hard (or not very demanding of their oil -- excluding TS engines then)

A5/B5 has the same high ZDDP content but lower film strength compared to A3/B4.

Neither are very good for catalysts or DPF's, so especially cars equipped with a DPF often get a ACEA C-rated oil, where C3 is the one with the highest level of protection. C4 is slightly less protective of the engine but a bit more for the DPF.

I know, but the car has run 110.000 miles on 20K.

Selenia Gold Synth looks like the most comparable product. For a twin spark it is basically equivalent to 20K. I have actually used this in a Tipo 16V which also called for 20K originally and it worked well. No worn cams or spun big ends after years of track miles.

All being well I should have my 3-Door Tipo Sedici on the road for the summer .
Need a oil change though, but Walkers Lancia are just down the road and use Fuch oils for their Delta's, although the Sedici is not blown engine (at the moment) Fuch oil will be going in the tea pot, just like the GQV, only a different grade of may be!

My previous oil being Millers fully synthetic for petrol XFS or diesel XFD from memory! But they have since dropped probably because cars now have Cats, DPF and many have blown engines these days. The tea pot has been under a SORN for years now.

I'm using Valvoline Long Life in my TS now. Was always run on 20K but figured Valvoline won't hurt in an engine with over 192,500 miles on clock .. ;-)

I'll probably just use GOLD instead of 20K.

So my question: did they stop making Selenia 20K?

And another question: 20K had a 10W40 SL/CF rating, whilst GOLD SYNTH now has a SAE 10W-40, API SM/CF, ACEA A3/B3/B4

Confused ...
Still makes it. uk site, on the link, FULL LIST.

Been to my local parts shop a few days ago and saw that Selenia GOLD Synthetic is now labeled as a API SN grade oil.

It is quite normal for oil to get re-rated with the current API code.

forget about API grades, they're meaningless if there's a much more specific ACEA grade or manufacturer approval.
