losing oil fast

[kfelec]

i have a vauxhall vectra sri 2003

and its starting to lose a lot of oil every week or two when its been filled up its losing it, its not leaking on the floor and there is no smoke coming from it,

any ideas were it could be going?

 

[Peter.N.]

Well, it either has to be leaking or its being burned. Check round the back end of the car for signs of oil on the bodywork, it could be blowing out at speed in which case there should be some evidence of it.

The alternative is that its only being burnt at speed and therefore the smoke is well diluted in the exhaust. An exhaust gas analysis should show if its being burnt.

Have you looked for an increase and traces of oil in the coolant ?

 

[kfelec]

just checked and there is black smoke marks at the back of the car by the exhurst, so how is it burning?

Engine wear, probably piston rings and or valve stem oil seals. Not cheap to fix. But get a good mechanic to double-check it for you.

It's the non turbo SRi ?
