This a well-known term in our trade. It is used for services such as fuel injector cleaning, crankcase flushes, etc. etc. These are services of little or no value and services you will not find recommended in the maintenance schedule that your vehicle manufacturer provides. There is nothing to stop a dealership from writing its own maintenance schedule that looks very official and which is loaded with “wallet flushes.” When an oil and filter change is promoted for $19 – $39, the facility that offers it loses money unless they can use the cheap oil and filter changes to sell other services which are, all too often, “wallet flushes.”  Don’s Automotive does not condone “wallet flushing,” and does not give away oil and filter changes as a marketing strategy. We price our oil and filter changes at a realistic level for professional service and ethical advice about your car’s service needs. Some people like this, some people don’t. If you choose to take advantage of loss-leader pricing for an oil and filter change, please consult your owner’s manual service schedule when additional services are recommended.
