According to a website I was looking at :
For a 1995 Mercury Cougar , 4.6 litre V8 engine
( 15 city / 23 highway miles per U.S. gallon )
A ( 1996 ) Mercury Cougar gas tank capacity is ( 18.0 U.S. gallons )
The ( 1996 ) Mercury Cougar gas tank capacity is ( 18.0 U.S. gallons )
For a 1995 Mercury Cougar : ( " regular " unleaded gasoline , 87 octane )
Fuel pressure regulator.
we had a 2000 Cougar that always got 32 mpg..
The ( 1996 ) Mercury Cougar gas tank capacity is ( 18.0 U.S. gallons )
For some reason the gas is not completely combusting causing water to be expelled in the exhaust pipe.
I was looking at the 1999 Mercury Cougar Owner Guide and it does not show that it has a gas cap warning light
According to my Chilton's Auto Repair Manual : ( A 1991 Mercury Cougar has a 19.0 U.S. gallon gas tank )
I can't say for sure , but the ( 1996 ) Mercury Cougar is ( 18.0 US. gallons ) * also the 1991 Mercury Cougar is 19.0 US. gallons
For a 2000 Mercury Cougar : The tank holds ( 15.4 US. gallons )
13 gallons
