Maintenance and care
232
It should not be necessary to add
any aftermarket products to your
fuel tank if you continue to use high
quality fuel of the recommended
octane rating. Aftermarket products
could cause damage to the fuel
system. Repairs to correct the
effects of using an aftermarket
product in your fuel may not be
covered by your warranty.
Many of the world's automakers
issued the WorldĆwide Fuel Charter
that recommends
gasolinespecifications to provide
improved performance and
emission control system protection
for your vehicle. Gasolines that
meet the WorldĆwide Fuel Charter
should be used when available. Ask
your fuel supplier about gasolines
that meet the WorldĆwide Fuel
Charter. In Canada, look for fuels
that display the Auto Makers'
ChoiceT logo.
Cleaner air
Ford approves the use of gasolines
to improve air quality, including
reformulated gasolines that contain
oxygenates up to 10% ethanol or
15% MTBE.
Do not use gasolines containing
methanol, which can damage
critical fuel system components.
Damage resulting from the use of
methanol may not be covered by
your warranty.
