Fuel E85 (85% Ethanol) - GMC 2010 Savana 1500 Cargo Owner's Manual

Also, your dealer/retailer has additives that will help
correct and prevent most deposit-related problems.
Gasolines containing oxygenates, such as ethers and
ethanol, and reformulated gasolines might be available
in your area. We recommend that you use these
gasolines, if they comply with the specifications
described earlier. However, E85 (85% ethanol) and
other fuels containing more than 10% ethanol must not
be used in vehicles that were not designed for those
fuels.
Notice: This vehicle was not designed for fuel that
contains methanol. Do not use fuel containing
methanol. It can corrode metal parts in the fuel
system and also damage plastic and rubber parts.
That damage would not be covered under the
vehicle warranty.
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. See Vehicle Identification Number
(VIN) on page 6-103.
If the vehicle has the 4.8L V8 engine (VIN Code A), the
5.3L V8 (VIN Code 4), or the 6.0L V8 engine (VIN
Code G) and the N15 flexible fuel option, you can use
either unleaded gasoline or ethanol fuel containing up to
85% ethanol (E85). See Fuel on page 6-5. For all
other gasoline engines, use only the unleaded gasoline
described under Gasoline Octane on page 6-6.
Only vehicles that have the 4.8L V8 engine (VIN Code A),
the 5.3L V8 (VIN Code 4), or the 6.0L V8 engine (VIN
Code G) and the N15 flexible fuel option 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%.
