I've seen a bunch of threads out there about this but not many solutions. My car burns oil when I vtec. I can see it (especially at night) in my rear view mirror. Looks like jet exhaust. ;-)

I had a compression test before I bought the car in Jan and the #s were supposedly good. I don't seem to burn any oil if I stay below 6k rpm. But surely, there must be something I can do/check/fix to stop my car from blowing smoke out its tailpipes.

Thanks,

PS. I'm using Mobil 1 10w30.

get a catch can!

I caught quite a bit of oil in 400 miles of driving, mostly when I drove spiritedly. Check your PCV valve also to make sure its functioning properly

A catch can is great for the track when turning hard. Seeing a steady plume of smoke out the back though is a whole different story when driving in a straight line or under moderate turning.

Run a compression and leak down test. That will tell you the whole story

Hmmm, mine does the same thing (02 with 89k) I am also curious, though, I thought that was normal for these cars... Mine will do it the most after I go a couple days of not going into VTEC. Wonder if its carbon blowing off at first?

could be the seals on the vtec valves.

i put about a quart of oil in my ap1 every week. Insane. I mean i have high miles to, but to be honest, i dont have any leaks and my engine is running strong so i cant complain, plus ill never need to change my oil becasue im constantly adding new oil to it
the filter, i change though lol

I am considering doing a compression test soon though, i just wanna make sure everything is 100%, ive never done one, so it cant hurt to do it.

try switching away form mobil 1. ap1s love to consume it. i used a syntehtic but swithced to a conventinal. castrol gtx 10w-30 and it didnt burn as much but still burns a good amount. my next step is to rebuild the head and get a low mile shortblock or something. my compression test was good too. 230 235 235 235.

jimnasty23

so even if your compression test is phenominal you can still consume lots of oil?

stop using mobil1, it burns easily

jimnasty23

any reccomendations on what oil to use besides mobil1? ive only used that, whats a better oil that doesnt burn as much?
