Vauxhall Astra burning oil

valve stem oil seals?check the engine for any visible leaks?does the engine knock?what mileage is your car as could be worn engine

Known fact that car tends to use oil .Could be valve stem oil seals/ valve guides/ piston rings and/or wear on cylinder bores .Take it's blue smoke ?
Others with same problem.

hey everyone,

my 01 astra is burning a lot of oil as well but i would also average 1000+ miles a month. i use 10W40 oil and i only notice smoke when the oil level is barely reading on the dipstick.
don't see any leaks and the car had a service in feburary

and

I have a 2003 astra cabriolet, my car seems to burn alot of oil.. no leaks anywhere!!! A mechanic told me they are prone to it

and

I don't wanna state obvious guys but if u read your owners manual page 250 something there is consumption rates and all astra use 0.6 litres of oil per 620 miles or as previously mentioned a litre every 1050ish. Mine does it too. Your dipstick from min to max is 1 litre so expect to be on empty of you don't check regular.

yes it s blue smoke and the engine only rattles when the oil is low , no leaks found at all

As previously suggested could be worn engine , might also be worth checking engine breathing system for any blockages / restrictions .Here is another owners solution ,

Had a similar occurrence on my old Astra 1.6L SXI (52 reg).

I had the car for seven years and what was odd is that the engine did not burn or leak oil.
But, every now and then the oil would just disappear.

I checked the oil every week and for five or six weeks with the oil level would be ok, then it would be on the minimal marker.

I came to the conclusion that the engine will burn oil if low.

So my work around was to fill the oil level till almost full and guess what it never used oil then from then on.

I suspect the 1.6L engines use oil if below some level but didn't burn a drop of oil if it was kept high (3/4 to nearly high marker).

This was my work around and I can say that in seven years of ownership this work around did help.

I have a same problem but the last suggestion to top the oil upto max level really helped?

my drives well therefore can't find any problem.

THanks
