Actually, because synthetics generally have a higher HTHS rating vis-a-vis
the static viscosity, (compared to conventional oils) they are more viscous
under high stress condtions and that can reduce fuel economy, although the
difference is slight.

For most street vehicles under average conditions, synthetics only make sense
for extending drain intervals. It's amusing how many people are wasting
their money draining synthetics at 3-5K service intervals. This seems to be
an American cultural idiosyncrasy, because there is no technical basis for
such a practice.

So what do you sell bud

go look at Mobil1 site and see the taxi test video, non severe driving
is what highway driving is, most of us in the US live where driving is
considered severe.
