    I have an l67 with 2 cylinders reading 60psi. I'm just wondering if 2 down cylinders and random misfiring on the 2 would be the cause of high fuel consumption? Averaging around 17l per 100? If I get the cylinders fixed will my economy dramatically increase or would something else be causing it to be so high? Thanks

    Some say 17l per 100 is heaps for what's wrong with it and some say that it's normal for what's wrong

    My tired old n/a vx averages around 13.7 -13.9 so its not like you'e totally horrendous fuel use but those 2 cylinders are pretty much dead

    Alright cool. Just not sure if theres other issues causing the high usage or if it's just because of compression is all

    Can' even find any other causes when the engines currently stuffed it needs fixed the more you drive it the more expensive it will get to fix if the cause of the lack of compression is doing more damage.if the rings are broken its gonna be eating the bores if the headgaskets gone its gonna be eating the block away and need a full teardown to surface the block faces black to flat you could even just have a bit of headgasket or other material stuck on a couple of valves holding them just off fully seated will lose a lot of comp
