****. I'm driving my early 2020 Octavia (mkIII) Scout (2.0L diesel DSG-7) through France, and only after I filled up (31L of the 55L tank) from the "diesel" pump I noticed the marking "B10" which apparently really exists about only in France, I'd never heard of nor seen before, and is officially (per Skoda) not compatible with this engine.

I don't find "B10" mentioned at all in the forums, and I find only few, vague mentions online in general about how B10 diesel (90% mineral diesel +10% bio diesel) can gum up diesel filters, degrade some engine parts, etc.

Anyone have experience with whether just (slightly less than) one single tank of B10 would be so noxious that I Shouldn't Drive It At All until I can get service to pump out the bad tank of fuel, or whether it'll be okay?

thank you,

Jay

If you haven't seen loads of diesels 'broken down' by the roadside so far in your journey through France then I would not worry about it.
