Mobil 1 5w40 FS2

[volk06]

Yesterday while I was at AAP looking for the 0w-40 rotella (they had none sadly), I saw this European Formula oil on the shelf and I've never seen it before and it wasn't on the US Mobil 1 site but found it for the south asia pacific areas. It was not formula M. It looked similar to Mobil 1 0w-40 FS but the label had FS2 on it. It does not meet the MB 229.5 unlike the 0w-40. Is this a new offering the US or am I just behind? I took a picture but didn't save it apparently.

I thought i put this in the euro forum but I messed that up. A mod can move if needed.

Never seen it before either.

The fact that it does not meet MB 229.5 likely means Noack is above 10%.

I haven't seen or heard of aforementioned. Thanks for posting Volk06.

I would guess the Mobil 1 0W40 FS with MB 229.5 is Group IV PAO based, while the Mobil 1 5W40 FS-X2 with MB 229.3 is Group III based. Castrol had something similar going on with Castrol EDGE 0W40 and Castrol EDGE 5W40.

Noack Volatility, the 0W40 is
HTHS is 3.6cP for the Mobil 1 0W40, but 3.8 for the Mobil 1 5W40.

They are both high SAPS Euro A3/B4 oils, with high TBN.
Both carry VW 502/505 and Porsche A40, so they are good oils.

I assume they both carry the usual Euro amount of about 1000 ppm ZDDP.

So if chasing MB229.5 or Noack then go the 0W40, but if chasing a higher HTHS performance oil then go the 5W40.

First time for me seeing it too.

Autozone sells it too https://www.autozone.com/motor-oil-...-oil-full-synthetic-5w-40-1-quart/1092005_0_0

I’ll bet it’s a Kia/Hyundai theta targeted offering.

Both MOBIL 1 FS 0W-40 and MOBIL 1 FS X2 5W-40 contain up to 20% of PAO group IV.
