The only thing I have found is a mention of their support for B5 (5% BD).

I have a local service station that sells B20, and can get B99.

I suspect they will not allow its use.

I came from a Lexus 400h with 23-26 MPG. I have so far (800 miles) averaged 21 MPG. Very disappointing, but I find it hard to drive this car like a Grandma (to get the best MPG). Fun to drive, though!

This diesel should have lower climate change emissions.
