The DIFM Channel: Who's Up, Who's Down?

摘要

It's no secret that there has been a marked shift from the do-it-yourself (DIY) to the do-it-for-me (DIFM) channel over the past 10 years. Back in 1995, nearly two-thirds of aftermarket consumer automotive lubricants were purchased at mass merchants, auto parts stores and other retail outlets. For millions of drivers, that habit is entrenched. After buying engine oil through such outlets, they routinely slide under the car with a drip pan and a rag, a drain-plug wrench and oil filter wrench (or sometimes just a screwdriver and a hammer). They then change the oil themselves.
