2016 Hyundai Elantra GT fuel additives

Introduction
41
Other fuels
Using fuels such as;- Silicone (Si) contained fuel,
- Ferrocene (Fe) contained fuel, and
- Other metalic additives contained fuels,
may cause vehicle and engine dam-
age or cause plugging, misfiring,
poor acceleration, engine stalling,
catalyst melting, abnormal corrosion,
life cycle reduction, etc.
Also, the Malfunction Indicator Lamp
(MIL) may illuminate.
✽ ✽ NOTICE
Damage to the fuel system or per-
formance problem caused by the use
of these fuels may not be covered by
your New Vehicle Limited
Warrenty.
Gasoline containing MMT
Some gasoline contains harmful man-
ganese-based fuel additives such as
MMT (Methylcyclopentadienyl
Manganese Tricarbonyl).
HYUNDAI does not recommend the
use of gasoline containing MMT.
This type of fuel can reduce vehicle
performance and affect your emis-
sion control system.
The malfunction indicator lamp on
the cluster may come on.
Do not use methanol
Fuels containing methanol (wood
alcohol) should not be used in your
vehicle. This type of fuel can reduce
vehicle performance and damage
components of the fuel system,
engine control system and emission
control system.
✽ ✽NOTICE
Your New Vehicle Limited
Warranty may not cover damage to
the fuel system and any perform-
ance problems that are caused by
the use of fuels containing methanol.
Fuel Additives
HYUNDAI recommends that you use
good quality gasolines treated with
detergent additives such as TOP
TIER Detergent Gasoline, which
help prevent deposit formation in the
engine. These gasolines will help the
engine run cleaner and enhance per-
formance of the Emission Control
System. For more information on
TOP TIER Detergent Gasoline,
please go to the website (www.top-
tiergas.com)
For customers who do not use TOP
Tier Detergent Gasoline regularly,
and have problems starting their
vehicle or the engine does not run
smoothly, additives that you can buy
separately may be added to the
gasoline.
If TOP TIER Detergent Gasoline is
not available, one bottle of additive
added to the fuel tank at every
7,500mile or every engine oil change
is recommended. Additives are avail-
able from your authorized HYUNDAI
dealer along with information on how
to use them. Do not mix other addi-
tives.
