Is low milleage on ej8 normal?

Hey guys, the mechanic rang me earlier tonight saying that there was 2 big holes (shown in the pic) and 4 smaller holes so yeah he wielded all them back in together for $70 now. And im not entirely sure which part t is but i think its the catalyst converter (something like that, its located like in the centre like right where centre console is).

I hope my fuel consumption can be fixed because like 300km on full tank is soo not i was expecting in a civic. If that doesn't fix the problem i might change the o2 sensor and if that doesnt work out then....i dunno =\

This is a bit obvious but... tyre pressure? injectors?

completely random, Can someone give me a link for denso o2 sensor for d16y4? i have the same problem as matt

Part number 234-4099

My tyre pressures are normal, not sure about injectors. Anybody know how to clean them? Just the obvious take out and clean with like towel?? lol

just something to compare, my ej8 does about 450km then the fuel light comes on, it's stock, with n*power headers, a pod filter and heavy 17's and manual

Either run some injector cleaner or get them ultrasonic bathed

What is ultrasonic bathed? I have been a mechanic for 7 years and have never heard of that. The best thing to do to get injectors cleaned would be to find a mechanic workshop that is an authorised Carbon Clean workshop. Pretty much it is an on car injector & fuel system cleaning machine that I personally believe is the best available on the market. It cleans the fuel rails, injectors, carbon deposits built up around the valves/combustion chamber/piston crown, the O2 sensor & the cat converter. You will pay around $180 but it is well worth it. You pay similar prices just to get someone to pull the injectors out & put them on a bench cleaner. Bottles of fuel system cleaner only work after many treatments and you will not see an immediate results

and Charlie there is no point just throwing up more idea's as it what could be the cause of his poor fuel consumption. Without doing proper checks first, throwing up idea's and making it sound like you know what you are on about ends up costing alot of money. He is on a student budget, so every time he spends money on something that doesn't work will delaying him from fixing his initial problem. Newtons Law: If it ain't broken, don't fix it!

Oh i might do that in the next couple weeks.

Update: Guys my dad has just found out my timing mark align was not right using the Inductive Timing Light, we adjusted it and its in the correct position. I'll see if this improves my millage and if it doesnt i'll consider an injector cleaner.

All of the things i've mentioned are cheap fixes and fixing poor fuel economy is a process of elimination is it not? How is he supposed to just pinpoint out of the blue the exact cause? Better to do it early than keep throwing away money on fuel. I was getting 250 a tank and didn't bother to fix it for over half a year. Who knows how much $$$ was wasted...

Ultrasonic bath is just another method of cleaning the fuel injectors. It's expensive which is why i only stated it as an alternative to a quality pour-in injector cleaner.

Oxygen sensor $60, injector cleaner $8. How is that 'alot of money'?

Ok guys i thank you for helping me, but yeah we all have our opinions, its a community for helping its what we do. Also charliebrown is the injector cleaner like a diy kit or does mechanic have to do i?
