I have just done a test as i was sure my car was caning the oil.
Over 1000 miles it used about 1.3litres .
I'm using castrol magnatec 5w/30.
There are no oil leaks , it runs fine & does not appear to be smokin'
any ideas ?
Wrong oil, it only meets ACEA A1, it has to meet ACEA A3 and LL01. It's to thin and worse the HTHS is to low so you get high consumption, increased shear, early onset of sludge and accelerated wear. Very few XW30 oils meet spec.
