Not getting impressive fuel economy with the Civic

anyway what kind of driving do you do?

Well I use the car for my work (I do food delivery for an Italian restaurant) so it's a lot of stop and go driving. My driving style during work is sometimes aggressive (which I can understand), and sometimes even relaxed.

Outside of work, I am very easy on the vehicle but the fuel economy isn't much of a difference.

And as for a compression test, good point. I hope I have proper compression, but who knows?

Thanks for the suggestions.

who did the timing belt? when I had mine changed they screwed it up and had it off by one notch, after that I could really tell when the v-tec was kicking in (it should be smooth and hardly noticable) my mileage droped, and power droped, normaly the v-tec-e engine has alot of power.

A shop that knows Hondas inside and out.

man it would help if you had a gaslog so you could see exactly where it fell on its face...

That doesn't alwas meen it was done right, on most Honda's you line the marks on the cam sprocket up with the top of the head, but if you read the shop manual you'll notice that the VX is the exception, and that there are little arrow marks on the head that you line the sprocket up with insted, and over confident mecanic might not notice this set of marks and line the cam sprocket up with the top of the head insted, and this is wrong, of course you can check this your self by taking the cover off the cam gear, and lining up the crank shaft pully with the Top Dead Center mark, if everything is correct then the TDC mark will line up at the same time that cam gear marks line up with the arrow mark on the head.

the other option is to take it to the honda dealer, and ask them to take it for a test drive to figure out what is wrong, after all you said that you could tell when the vtec was kicking in, and this shouldn't be the case, other then a very very slight increase in power.

I used to keep track of receipts by putting the amount of miles the fuel tank filled up, but my dad threw them away by mistake

So what readings should I expect in a properly maintained VX?

[DUBPL8]

160psi on 1, 155psi on 2, 155psi on 3, and 135psi on 4

Got my compression test results in.

^^^^ that number 4 is a bit low....did you do it twice to verify numbers, or run a wet test?

Ran it twice to verify the readings and they stayed consistent.

Wet test? Do you mean leak-down test? If so, no I didn't do that. Should I do that to better determine the issue at hand?
