gas mileage? - Page 2

wow.....all of you guys are getting so much better mileage than I am.... I have a question.... would having a blown head gasket have anything to do with bad mileage because I believe I have a BHG. Also I was wondering how much better mileage would I be getting if I changed my spark plugs. Thanks.

I believe that having a BHG would kill gas mileage as it would alter your compression.

If the spark plugs are really gunked up then it will make a difference. If they are only slightly worn you won't notice much by changing them.
You definently need to focus in on the BHG issue first though.

hey i came up from florida to ct and spent about 160 in gas i have a 87 5spd i think when you do city driving the stop and go traffic do help because you constently are increasing and decreasing your speed it waste more gas srry bout the spelling
