I have a 1098. I always run premium. I think these cars like it,
especially modern gas formulations. The additives will help keep
your carbs clean inside, even if the engine doesn't need the
extra octane. ..
When I first got mine it didn't yet have hardened valve seats so
every tank I put in a tablespoon of lead substitute. Easy to keep
in the trunk along with a metal measuring spoon.
YMMV.. my 2 cents.
