I question to question how oil change places make money on that business model. Oil changes, even at a full price, are generally low profit for the time of writing up new customer till they leave vs other repair work.
When i started our business plan I viewed oil changes as means to growing a customer base for future repairs. Of course we inspect cars and report legitimate maintenance and repair needs but we do not push hard unless its a serious issues. I believe the quick lube stores have put a bad impression for high pressure sales and ad ons. As we progress in business I may start to see some potential from the little profit made as long as it doesn't take away from repair work. We do not market ourselves as a quick lube business but its an easy way for future customers to test the water and an easy way for us to win them over.
How much of your model is from oil change profit and what is your attach or future sales rate on these customers.
also, these oil changes are messing up my per ticket average so I can get some solid sales numbers. Do you include them in your per ticket average or run them separate(if my software can separate them)?
