Ted gets his oil changed every 3,000 miles. Last time, the quickie oil change guy convinced him to switch to synthetic. Ted checked the oil after about 4,000 miles, and didn’t like how black it looked, so he switched back. Is synthetic oil a scam? Tom and Ray say the oil looking black was a good sign; it meant it was doing what it was supposed to do. But Ted is getting his oil changed too frequently. He can go 5,000 miles with regular oil.
