I'm wondering if its normal to burn a half quart of oil every 1,000 miles. Thinking that maybe it was the quality of oil I was putting in my 2010 CRV, this time I used Mobil 1 High mileage advanced full synthetic 0w20 and it is still burning a half quart of oil every 1,000 miles. Any suggestions on any additives that might help curb the amount of oil I am burning? Its garage kept and the floor is bone dry everyday so I know there is no leak. Your input is appreciated.
