2015 Hyundai Accent oil additives

Introduction
4 1
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 per-
formance and affect your emission con-
trol system.
The malfunction indicator lamp on the
cluster may come on.
Do not use methanol
Fuels containing methanol (wood alco-
hol) should not be used in your vehicle.
This type of fuel can reduce vehicle per-
formance and damage components of
the fuel system.
Fuel Additives
HYUNDAI recommends that you use good
quality gasolines treated with detergent
additives such as TOP TIER Detergent
Gasoline, which help prevent deposit for-
mation in the engine. These gasolines will
help the engine run cleaner and enhance
performance of the Emission Control
System. For more information on TOP
TIER Detergent Gasoline, please go to the
website (www.toptiergas.com).
For customers who do not use TOP Tier
Detergent Gasoline regularly, and have
problems starting 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 available from your author-
ized HYUNDAI dealer along with informa-
tion on how to use them. Do not mix other
additives.
Operation in foreign countries
If you are going to drive your vehicle in
another country, be sure to:
Observe all regulations regarding reg-
istration and insurance.
Determine that acceptable fuel is avail-
able.
CAUTION
Your New Vehicle Limited Warranty
may not cover damage to the fuel
system and any performance prob-
lems that are caused by the use of
fuels containing methanol.
