Anyone here have damage from bad gasoline?

Have a friend in NY state who's car died shortly after fillup (Acura TSX). A fuel sample confirmed bad gasoline (milky white appearance).

The dealer has said repairs are likely to top $800, and of course this isn't covered by warranty.

Questions:

-What types of long-term effects (if any) should he be on the lookout for?

-Without warranty coverage, what recourse, if any, does he have to recover the repair costs (isn't gas station liable)?

Anyone have experience with this?

Thanks!
