spark plugs CHEVROLET HHR 2010 1.G Owners 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/retailer for service.
Fuel E85 (85% Ethanol)
The 8th digit of the Vehicle Identification Number (VIN)
shows the code letter or number that identifies the
vehicle's engine. The VIN is at the top left of the
instrument panel. SeeVehicle Identification Number
(VIN) on page 6‑118.
If your vehicle has the 2.2L L4 engine (VIN Code B) or
the 2.4L L4 engine (VIN Code V), you can use either
unleaded gasoline or ethanol fuel containing up to
85% ethanol (E85). See Fuel
on page 6‑5. In all
other engines, use only the unleaded gasoline
described under Gasoline Octane on page 6‑6. Only vehicles that have the 2.2L L4 engine
(VIN Code B) or the 2.4L L4 engine (VIN Code V)
can use 85% ethanol fuel (E85). 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.eere.energy.gov/afdc/infrastructure/locator.html)
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.
