Fuel Quality; Gasolines For Clean Air - Ford 1996 Escort Manual

Fuel Quality

If you are experiencing starting, rough idle or
hesitation problems when the engine is cold, it
may be caused by fuel with low volatility. Try a
different brand of fuel. If the condition persists,
see your dealer or a qualified service technician.
Using a high-quality fuel makes your vehicle
more responsive and maintains its good fuel
economy and emissions by:
protecting your fuel system from rusting.
protecting your fuel lines from freezing.
improving vehicle starting and warm-up.
protecting the fuel system from vapor lock in
very hot weather, which causes the engine to
hesitate or stall and makes restarts difficult.
minimizing deposits in fuel injectors,
combustion chambers and on intake valves.
preventing the fuel system from "gumming
up" when your vehicle is not used for long
periods of time.
It should not be necessary to add any
aftermarket products to your fuel tank if you
continue to use a high-quality fuel.

Gasolines for Clean Air

Fuels in certain areas of the country are required
to contain oxygenates to improve air quality.
Common oxygenates are ethanol or grain alcohol
(blended at no more than 10%), methanol or
wood alcohol (blended at no more than 5% with
cosolvents and additives) and MTBE or methyl
tertiary butyl ether (blended at no more than
15%).
