Just received my lab report on the last oci.
Shell Helix Ultra 0w-40, 10782km (6735mi) in a Saab 900 turbo 16V (B202L).

Wear rates looks good .... more so for this high mileage engine, which appears to be performing normally.

The used oil condition still looks good, with very mild viscosity thinning.
From the Blotter Spot Test picture provided, dispersancy is still very strong with minimal insolubles being present ...... seems to be in compliance with your dispersancy index reading of 85%.This index is rarely provided in Bitog.

I believe this used oil is still serviceable, and you could consider extending oil change interval to 15000-18000 km.

Do you mistake Helix Ultra 0W40 for Helix Ultra 5W40 ?

Just my 2 cents. blush

Just curious, why SHU 0W40 mistaken for 5W40?
I can get SHU 0W40 cheaper than 5W40, but it is on the thin side of a 40, and I always (mistakenly?) thought it was a weaker sauce than 5W40.

Oops, my bad .... you mean SHU 0W40 is readily available in Europe?
Over here,no SHU 0W40 is available.

Very interesting.

The BN in all three cases seems very very high.

It is available in Germany, for 20€/5L, which is the cheapest 0W40 I can find here smile
5W40 is available in any supermarket.

It is the cheapest 0w-40 that I know of. It certainly is the cheapest 0w-40 with MB 229.5 and Porsche A40 approvals...
I buy mine here:

I think there are two contributing factors.
1) the car is mostly used for medium and long distances. Short tripping is rare. As in one or two grocery runs a week and one trip to the boat house. And then it is 2x600km long distance commute the next weekend. So perhaps 90% of my km are long distance-drives. So not much to worry about fuel dilution (although these cars do run very rich on full boost). And also not much condensation...
2) ultra-low sulphur fuels (10ppm).
Also, the car is filled up mostly at the "big brands", and only very rarely at independent gas stations. (In theory, better quality controls and maintenenc of the stations should reduce the risk of contaminated fuel. Also, you might not know which fuel the independ sells - it might be exactly the same as the brand station on the other side of the road, it might also be that he has bought just the cheapest add pack... you just do not know.) Fuel grades varie -I mostly switch between e10 and 98, or even 100 (Shell, ÖMV) or 102ROn (Aral).

Maybe, but I would question the lab on what exact method they use to measure BN. You're pretty much remaining at virgin TBN.

If they are accurate, then you'll never need to change oil, unless fuel dilution actually causes problems like reducing your BN!

As far as I know, there are two different methods to measure TBN, that give slightly different readings. So my TBN measured by the other method might show a bit lower than stated on this sheet; but it should still be far from critical...

You're probably right that with any of these oils (be them GTL, or mostly PAO-based like the other two) I should be able to extend oil change intervals drastically. 20.000km sound totally doable. That is, as long as my driving pattern does not change...
I would strongly advise against anybody with the same car, but a different usage pattern seing my UOAs and concluding he can extend intervals. He might, but then he might not... We simply do not know wether the high remaining TBN is a result of sulphur-free fuel or of the driving pattern. (I remember seing a german UOA by the same lab of a short tripped VW 1.4 TSI with high fuel dilution, atrocious wear numbers, wich also showed low TBN. I also know a guy that put 1,2 million kilometers on a little Skoda Fabia TDI, who, adter doing some UOAS early on, extended his intervals to 60.000km. That is a 37,290 mile oci for the better part of a million kilometers... But then, again: ultra low sulphur fuel and no short tripping.)

I believe you belong to another league whose OCI is 20K-50K km.
Just speculating blush

We have low sulphur gasoline and lots of highway driving in CA too.

But no UOA with better TBN than VOA grin

The TBN figures are just not possible, one of them is even higher than the VOA.

The UOA results are good and the OCI could be extended, BUT I would try another LAB to find out what the real TBN figure is first.
I use a min TBN figure based on one third of the original, not the minimum figure of one quoted by some labs.
