Icon2 Need Help, Compression Test Results!!

Well I did a compression test with my friend and here are the numbers, PSI, it showed on the gauge on each cylinder.

From front of the engine to rear, or if ur facing the car it would read right to left, First Cylinder read 225 PSI, Second and Third both read 210 PSI, and the Fourth and final read 215 PSI. Can someone tell me if this is good or bad and if the pistons are the reason my engine is consuming over a quart of oil or more in a month 3-4 weeks period, thank you...

looks good to me. you dont want more than 10-20psi difference between cylinders
how much are you driving in that 3-4 months? like 4000 miles?

well because I work for canada dry and I packout different stores they send me to so many stores back n forth even though its local, so lets say I been their for 3 months + my normal driving I put about 6-7000 miles. Yesterday I hooked up an air fuel ratio gauge and it works great so I know my 02 works fine because a couple times i was late for work and as soon as i started it the check engine light came on for the code P0133 = 02 Slow Response, it only happened twice though not all the time, but now we realize that didnt cause the hesitation that Im having now, then we clean the throttle body and did the compression test. So were stumped, if compression is good and it holds the pressure, the 02 is good, What can possibly cause my oil consumption and hesitation?


P.S. It only hesitates if I start off drivin normal like if Im at a red light and just press th gas slowly to drove normal n smoothly but if I get on it and put at leats half throttle or 75% then it will take off smoothly.

Compression numbers seem good.
Do a "wet" test as well.

Try cleaning out your IACV valve, that may help your hesitation problem.

There's no need to do a wet test if the dry test came out good. Now, if one cylinder was fairly low, a wet test might lead in towards the problem. Anyway, see if you have any leaks. And what weight oil do you use? Hit VTEC much? As for the code, there's a little "heater" in your O2 sensor that helps it warm up instantly, which can go bad over time. Sounds like yours has. Not a big deal unless you live in a cold climate

well as u can see the test results up top doesnt seem bad at all, vtec yea i do hit a lot no lie, and my climate i live in NJ only cold in winter but not that cold summers are real hot n humid. my air fuel ratio gauge seems to work fine so the 02 has got to be ok, I usually use 10w 30 oil, i cant see any external leaks at all and there are no signs of oil leaks on the ground either, im just confused by it...

My mom's Accord is the same way. Every few weeks you have to add 1/2 a quart of oil. Doesn't smoke, doesn't leak. Been doing it since 40k miles or so
