Was wondering if the selenia oil is actually any good.
How does it compare to motul syns and m1 for example?

What is it's VI and hths?

What is it's detergent package like? What group is it?

14.9 cst at 100 is all I could find on its data sheet.

I wouldn't use any oil for 20k. Just thought it may have a good detergent package if it's a long oci oil.
I change my oil every 5k regardless of the type of oil.

It is almost 3 times cheaper than the motul I am using.

In the UK Euro Car Parts sells Petronas Syntium (in its various forms) and I have just put some Syntium 5000 AV in the 159.

Petronas (Malaysian owned) make Selenia and of course are big sponsors of F1.

The oil I put in the 159 was made in Italy

I change the oil in between standard oil change intervals so I thought I would give it a try as in my opinion new oil is better than old oil.

Previously when I have changed it I have used Mobil 1

It has been in 1000 miles now and the car has not seized up.

The problem with oil is how do you know in the short term how it has protected your engine?

There is always a lot of discussion on the Sud forum debating 'synthetic versus mineral' in Sud engines.

I use Shell Helix 15w/50 Synthetic in the Sud and usually chage it sub 3000 miles.

I work on the principle that the Sud engine was modern in 1972 and every handbook I have seen on the Sud has just been updated to recommend the latest type of oil sold by the brands that Alfa recommend.

My wife used to have a Metro Turbo in the late 80's and I used to run it on Mobil 1. Now that old A series was an old engine and the oil is used to lubricate the engine, turbo, gearbox and final drive.

I used to love Mobil 1 because even though the car was used around town and it was in the era when 'black sludge' used to kill engines, whenever In used to take the rocker cover off underneath it was always clean and prestine but if you touched one of the rockers with your finger it left a fingerprint in the oil film that was left covering the engine.

It was not a great car but when I used to use it I used to love thrashing it and when coming off a motorway slip road i used to stop the car open the bonnet quickly and see the Turbo glowing red.

Sorry Brit got carried away there - what was the question again?:)

:lol::lol::lol:

not sure now after reading your answer!

Petronas! ah I was thinking it was Petrobras. Brazilian oil company here.
my bad.


going to keep trying the 300v motul stuff. pricey but at least I know its group V and very good.

may try the 5w40 next instead of the thicker 15w50. or even a 50/50 mix

Hi Brit,
I used Selenia 20k in my Alfa 156 for 110k miles without any issues. It obviously did a great job as the engine used no oil and the original variator was still perfect. I did oil/filter changes every 6k miles (10k km).
Shame the Selespeed gearbox failed which killed the car by being uneconomic to replace!
Whether the oil sold in S America is the same stuff - only you can judge.

I used 20k over 100,000 miles... and changed it every 20k, like it says on the tin. :)

The motore eventually needed a head gasket so it was a good chance to peep in there and have a look how the engine oil had been doing its job.

The oil that came out was always "oily".. it felt springy between my fingers, so it was still doing its job.

Mechanical wear was almost non-existent. The cam lobes were splendid (bearing in mind teh beast is a v6, and they can wear on the cam lobes)... the rockers never needed adjusting .. and I still had hone marks on the bores. So in terms of protecting the engine, the 20k did a splendid job.

The inside of the engine did show a lot of gum and varnish, though no black sludge. Some of the oilways (which are about 6 or 7mm wide had a thin coat of gum round the inside, rather like a middle aged guy who needs less cholesterol in his diet... but the car had 200,000 miles on it.. and the oilways were essentially clear.

The beast never broke any engine component (oil pump, shells, bearings, rings).

The oil would burn off when it go hot and I did need to top it up. I think the car used 1 ltr every 6000 miles but it had a rocker leak which probably accounted for some of it.

I've since moved to a higher detergent oil just to see if I can reduce the brown gum in the engine.. although it's not harmful and I can't actually see it.. (OCD! :D ) but I think the answer is to change the oil more often (6000 miles/10k). However, the oil will not be worn out.. so it's just peace of mind.... but anyway, Selenia 20k does the job. :thumbs:

Agree with that. Selenia 20k is a good Group II semi-synthetic oil, but I would personally change it at least every 6,000 miles to keep everything a bit cleaner. If you're more seriously into oil performance, then you need to look at true synthetic oils, such as Fuchs Race Pro S, which is a Group IV/V Ester based true synthetic.

Thanks guys.
In fact the oil turned out to be standard syntium and not 20k.

Will stick with 300v motul group v.

How good is selenia oil 10w40 alfa 20 k

Hi Brit,
I ride still years on motul 300 v with my motorcycles .idid always 15-20000 km (10-13000 miles)and i am very happy with the oil and satisfied .
Later on i had many Renaults on gasoline and ride with fully synthetic Elf and did 300000 miles with the same engine
Now i have also a BMW 535 v8 and have most of the time Castrol in it but i hav oil consumption 1 liter on 7000 km ,changed by the specialist to Valvoline and now 1 liter on 10-12000 km ,i am sure with motul v300 it gonna be less
Now i have also for my wife an Alfa 156 1,6 on gasoline and i reed many things about Selenia 20 k but i think to do Motul in it because i can buy Motul for 8 euro 1 liter here in belgium
Maybe the selenia fullsynthetic is even good like the motul ,??
Best regards
Patrick

Ive never found a place that sells selenia oils here in finland (ive been told there are a few small companies that import it thou) so Ive stick with valvoline oils for almost all of my alfa career. Havent had any problems regarding oils in any of our cars (33,155,156,159), and our 159 did 1200km per week last year, so theres some "milage" to back it up.

Changed oil every 3-4 months, so roughly at 20000km.... wouldnt even cross my mind to change them at 5000km eg. once a month....
