MMT In Gasoline
Methylcyclopentadienyl Manganese Tricar-
bonyl (MMT) is a manganese containing me-
tallic additive that is blended into some gaso-
line to increase octane. Gasoline blended
with MMT provides no performance advan-
tage beyond gasoline of the same octane
number without MMT. Gasoline blended with
MMT reduces spark plug life and reduces
emission system performance in some ve-
hicles. The manufacturer recommends that
gasoline without MMT be used in your ve-
hicle. The MMT content of gasoline may not
be indicated on the gasoline pump; there-
fore, you should ask your gasoline retailer
whether or not his/her gasoline contains
MMT.
Materials Added To Fuel
Indiscriminate use of fuel system cleaning
agents should be avoided. Many of these
materials intended for gum and varnish re-
moval may contain active solvents or similar
ingredients. These can harm fuel system gas-
ket and diaphragm materials.
