spark plugs GMC YUKON 2010 Owner's Manual

Some gasolines that are not reformulated for low
emissions can contain an octane-enhancing additive
called methylcyclopentadienyl manganese tricarbonyl
(MMT); ask the attendant where you buy gasoline
whether the fuel contains MMT. We recommend against
the use of such gasolines. Fuels containing MMT can
reduce the life of spark plugs and the performance
of the emission control system could be affected.
The malfunction indicator lamp might turn on. If this
occurs, return to your dealer for service.
Fuel E85 (85% Ethanol)
Vehicles that have a FlexFuel badge and a yellow fuel
cap can use either unleaded gasoline or ethanol fuel
containing up to 85% eithanol (E85). For all other
vehicles, use only the unleaded gasoline described
underGasoline Octane
on page 6‑7.
We encourage the use of E85 in vehicles that are
designed to use it. The ethanol in E85 is a "renewable"
fuel, meaning it is made from renewable sources such
as corn and other crops. Many service stations will not have an 85% ethanol
fuel (E85) pump available. The U.S. Department
of Energy has an alternative fuels website
(www.afdc.energy.gov/afdc/locator/stations/) that
can help you find E85 fuel. Those stations that do have
E85 should have a label indicating ethanol content.
Do not use the fuel if the ethanol content is greater
than 85%.
At a minimum, E85 should meet ASTM Specification
D 5798. By definition, this means that fuel labeled E85
will have an ethanol content between 70% and 85%.
Filling the fuel tank with fuel mixtures that do not meet
ASTM specifications can affect driveability and could
cause the malfunction indicator lamp to come on.
