So I had an oil change at 31,513 miles. I get rid of this car at 39,000 miles, so likely will be gone shortly before that mileage. Now my question is since I had a QS synthetic blend oil and most likely "el-cheapo" oil filter put on by the service dep't, do you think this oil will hold up till then? I'm at 35,400 now and at 61%. Thanks guys and God bless
