Ok fellas, as most of you know my motor is eating oil
I was originally using 5W-30 grade oil when I noticed oil consumption, to which I then switched to 10W-40 hoping to reduce the oil consumption and as it stands the motor is now burning around 500ml per 1000km.
Know I know the manual says we can use 15W-40 but Australia is currently in winter so it can get cold, is it safe to use this grade of oil when it is winter?
I plan to rebuild this motor next year with forged internals to take a centrifugal charger and just need this motor to hold out till then.

Just a little afterthought, would all this excess oil burning damage the motor block in anyway, as long as I keep the oil topped up I should be fine???

Oh yeah it has 75000 miles on the clock and is a 04 motor, it used to see track running once a month for two years till they closed down the course, it also sees spirited driving Atleast 2 times a week and casual driving sees 3500rpm shift points

As OldMan said and the W means winter not weight.

I would use a 40 weight oil and see if the consumption comes down and if not then it's serious and you can try to go heavier to buy you some time.

Thanks for the replies everyone,
I'm already using 10W-40 the brand is penrite, should I perhaps try a 10W-50 grade oil or even a 5W-50 grade?

Also I rechecked the oil after letting the car sit for half an hour after driving it and the consumption looks like its more 300-350ml per 1000km not 500ish like I thought is was (got incorrect reading when I checked it just after I drove it)
