fuel additives CHEVROLET EXPRESS 1998 1.G Owners Manual

Downloaded from www.Manualslib.com manuals search engine If your vehicle is certified to meet California Emission
1 Standards (inhcated on the underhood emission control
label), it is designed to operate on fuels that meet
California specifications.
If such fuels are not available
in states adopting California emissions standards, your
vehicle
will operate satisfactorily on fuels meeting
federal specifications, but emission control system
performance may be affected. The malfunction indicator
lamp on your instrument panel may
turn on andor your
vehicle may fail a smog-check test. If this occurs,
return
to your authorized GM dealer for diagnosis to determine
the cause of failure. In the event it is. determined that the
1 cause of the condition is the type of fuels used, repairs
, may not be covered by your warranty.
Some gasolines that are not reformulated for low
emissions contain an octane-enhancing additive called
methylcyclopentadienyl manganese tricarbonyl (MMT);
ask your service station operator whether
or not his fuel
contains MMT. General Motors does not recommend the
use of such gasolines.
If fuels containing MMT are used,
~ spark plug life may be reduced and your emission
control system performance may be affected. The
malfunction indicator lamp on your instrument panel
may
turn on. If this occurs, return to your authorized
GM dealer for service.

i
To provide cleaner air, all gasolines in the United States
are now required to contain additives that will help
prevent deposits from forming in your engine and fuel
system, allowing your emission control system to
function properly. Therefore, you should not have to add
anything to the fuel. In addition, gasolines containing
oxygenates, such as ethers and ethanol, and
reformulated gasolines may be available in your area to
help clean the air. General Motors recommends that you
use these gasolines if they comply with the
specifications described earlier.
NOTICE:
Your vehicle was not designed for fuel that
contains methanol. Don’t .use it. It can corrode
metal parts in your fuel system and also damage
plastic and rubber parts. That damage wouldn’t
be covered under your warranty.
