News paper under your engine, for a weekend, that will check for drips.

engines always burn a very small amount (blow by rah rah rah), however id say your mainly loosing it due to a leak, you just havnt noticed it.

oh wait, every 1000km's... is that REALLY big deal?

[blake22]

it definately doesnt drop any i've left it in the garage and it never drops it.. the cars only done 120km tho bought it off an old lady.. it shouldnt be burning any oil should it?

[Si]

what oil type are you using?

[Adamal]

Sounds like it needs a good thrashing. Load it up hard and press those rings against the cylinder walls.

15w 40 shell oil i used for the last service i think... haha yeah i've given it a good thrashing aye.. when i open it up theres no black smoke like its burning oil...

bluesmoke is burning oil
black usually just running bit rich

Thanks for that, but its not doing either.. confused me.. but then again im a plumber not a mechanic but have spoken to alot of people and they cant make sense of it either! especially for a car thats only done 120000km reg serviced etc... my dad has the exact same one and his doesnt use any oil and mine runs way better than his!!

probably owned by some cheap ass asian in Japan (unless its nz new) they dont seem to like changing the oil much so its probably a bit worn (the engine) and oil gets thru and is burnt with the petrol. Most of the problem is when engines cold I think, you may not even notice a slight bit of smoke from the burning oil

edit: lol at ass being buttocks....

[blake22]

yeah its nz new, with full service history, reacon it could be burning that much and theres just no smoke? what u reacon i do with the car?

[79rolla]

do you cheack if its smoking when its cold?
my care eats oil when its cold with the choke on
but its older and had a harder life

[Bling]

just keep it full of oil and you shouldn't have any problems

[big_boy]

check its not comeing out your oil filter under pressure & going on to the exuast & burning

[matt dunn]

It will be burning it,

but at that rate you will not see it.

Try different brands of oil as some engine burn more or less with different brands.

I've had quite good luck just using a catch can in my ae92. It's made a big difference to how much oil the engine burns. Install a cheap catch can to remove the water and fuel mist from blowby gasses, they cause the oil to degrade bigtime and makes it much more prone to being burnt up during combustion. So a decent new catch can setup PLUS new oil change should make a difference - oil lasts much longer.

early ecotec commodores would eat litre of oil every 1000km. and was considerd normal from factory....

I once read somewhere that if a vehicle is traveling around town alot (say 500km) then is given an open road burn, traveling at constant pace - no stop start city traffic, it will lose alot of its volum Why? The open road run holds the engine under load at higher revs working the oil. in doing so burns off the contaminants (the biggest is unburnt petrol, condensation) and when the oil is checked again (best to check before you go for the long journy) its lost a litre or so.
