So i just changed my sparkplugs to NGK V power copper! I gapped them to 0.44

before my changed them i would get 460-500km per 40Litres of fuel and then the low fuel light would go on( i would have 10 litres left)

Now after i changed the plugs my light has come on consistently around 400-420km before the low fuel light comes on.

my driving habit hasn't changed that much and my commute to work has been the same.


also another thing......
I have a crack in my exhaust manifold from when i bought the car but it doesnt seem any bigger than when i bought the car. I read on the forums that could cause poor mpg. I read it almost costs and arm and a leg to change the manifold. Will i have to change it or will it just give me poor mpg and i can just drive it out till the car dies. i also have the slipping auto tranny problem so i dont want to invest in the car. just riding it out till it dies. rather pay more in gas than change out the manifold


any ideas?

get that crack fixed/replaced.

and did you gap your sparkplugs properly?

PeterLazro

is my gapping to large or too small for it to cause lower mpg.

gap .44 or .044?

This was going to be my first question as I read the first post.

original plugs are platinum not copper, there is your problem

copper is actually a better performing plug over platinum.
