Improved my cars mpg to 4
 

My Lincoln Mark 4 was getting about 1 mpg in the city. But I decided to change the spark plugs and VOILA, i get great gas mileage, up to 4 mpg! and the power from my V8 7.5 litre engine is better, it just shoots off when i put the gas pedal all the way to the floor!:thumbup: I'm hoping to improve it even further soon.

:rolleyes:

You'll do even better after you add some speed holes. Make sure to post up piks when you're done! :D

That's a savings of over $348 just on your first tank:thumbup:

she'll go 300 hectors on a single tank of kerosene

Why don't you do us and the planet a favor and get a Hummer to tow that thing around with? ;)

I'm waiting for the linkback...

Pretty much anything would save money compared to that....

Don't know how that is even possible I have a 6-71 supercharger with twin 675cfm demon Carburetors on my Vette and I get around 7mpg if I drove it on the street and that is with a 3.90 rear and a 3 speed th-400.
