LINCOLN MARK VIII 1997 Owners Manual

246Octane recommendationYour vehicle is designed to use premium gasoline
for optimum performance with an (R+M)/2 octane
rating of 91 or higher. Gasolines with lower octane
ratings can be used, but performance and fuel
economy may decrease. We do not recommend
gasolines labeled as ªpremiumº in high altitude
areas that are sold with octane ratings less than 91.
Typical octane rating labelDo not be concerned if your vehicle sometimes
knocks lightly. However, if it knocks heavily under
most driving conditions on the recommended
octane fuel, see your dealer or a qualified service
technician to prevent any engine damage.
Fuel qualityIf you are experiencing starting, rough idle or
hesitation problems try a different brand of fuel. If
the condition persists, see your dealer or a qualified
service technician.
The American Automobile Manufacturers
Association (AAMA) issued a gasoline specification
to provide information on high quality fuels that
optimize the performance of your vehicle. We
recommend the use of gasolines that meet the
AAMA specification if they are available.
It should not be necessary to add any aftermarket
products to your fuel tank if you continue to use a
high-quality fuel.

To calculate fuel economy:
1. Fill the tank completely and record the initial
odometer reading.
2. Every time you buy fuel record the amount (in
gallons or liters) purchased.
3. After at least three to five tankfuls, fill the fuel
tank and record the final odometer reading.
4. Use these equations to calculate your fuel
economy.q
English: MPG = (total miles)/(gallons used).
q
Metric: L/100K = (liters used) x 100/(total
kilometers)
Comparisons With Environmental
Protection Agency (EPA) and Transport
Canada (TC) Fuel Economy EstimatesEPA fuel economy figures are obtained from
laboratory tests under simulated road conditions and
may not reflect the actual conditions you experience
or your style of driving. The EPA fuel economy
estimate is not a guarantee that you will achieve
the fuel economy shown.
The following decrease fuel economy:q
Lack of regular, scheduled maintenance
q
Rapid acceleration and excessive speed

Have the services listed in theMaintenance
Schedulebooklet performed according to the
specified schedule. The scheduled maintenance
services are required because they are
considered essential to the life and performance
of your vehicle and to its emissions system.In general, maintenance, replacement, or service of
the emissions control devices or systems in your
new Ford Motor Company vehicle or engine may
be performed at your expense by any automotive
repair establishment or individual using automotive
parts equivalent to those which your vehicle or
engine was originally equipped.
Ford strongly recommends the use of genuine Ford
replacement parts. If other than Ford or Motorcraft
parts or Ford authorized remanufactured parts are
used for maintenance replacements or for the
service of components affecting emission control,
such non-Ford parts should be equivalent to genuine
Ford Motor Company parts in performance and
durability. It is the owner's responsibility to
determine the equivalency of such parts. Please
consult your warranty booklet for complete
warranty information.

How to Prepare Your Vehicle for
Inspection/Maintenance (I/M) TestingIn some localities it may become a legal
requirement to pass an Inspection/Maintenance
(I/M) test of the On-Board Diagnostic (OBD) II
system. If the vehicle's powertrain system or its
battery has just been serviced, the OBD II system is
reset to a not ready for I/M testing condition. To
prepare for I/M testing, the law specifies that
additional mixed city and highway driving is
required to complete the check of the OBD II
system.
The driving modes required to reach the ready
condition consist of a minimum of 30 minutes of
city and highway driving as described below:q
At least twenty minutes driving in stop and go,
city type traffic with at least four idle periods.
q
At least ten minutes of driving on an
expressway or highway.Before completing the above driving modes, the
engine must be warmed up and at operating
temperature. Once started, the vehicle must not be
turned off during these driving modes.

following lights frequently:q
