Seasonally
adjusted gasoline
Many gasoline grades
are blended to perform
especia lly well fo
r
winter or summer
driving.
During seasonal change-over, we suggest
that
yo
u
fill
up at
busy gas stat ions where
the seasonal adjustment
is
more likely to be made in
time

Gasoline
additives
A major concern among many auto manufacturers
is carbon deposit
build-up caused by the type of gasoline you
use.
Although gasoline grades differ from one manufacturer
to another,
they have certain things
in
common. All gaso line g
ra
des
contain
substances that can cause deposits to collect on vital engine parts,
such
as
fuel
injectors and
intake
valves. Although most
gasoline
brands
include
additives to keep eng ine and
fuel
systems clean, they
are not equally effective.
Audi recommends
using
TOP TIER
Detergent Gasoline.
For more
information on TOP TIER Detergent Gasoline, please go to the officia
l
webs ite (www.toptiergas.com).
After an
extended
period of using inadequate fuels, built-up carbon
deposits can rob your engine of peak performance.

ULSD-Diesel No. 2
ASTM
D975 and Bio-diesel
