Being a relative n00b, I hope I posted in the right forum for my questions below. Like all of you gents, I'm passionate about oil, good-quality oil filters (no cardboard end caps if possible, lol), and tip-top running cars, and have been thinking about running either an oil change or a detailing shop. For those who have run an oil change shop before or currently (franchise or non-franchise - I'd be interested in the latter) and can provide tangible input, is it still profitable in this day and age, or are cheapie "$19.99 oil change" places undercutting the market and making it not worthwhile when you have payroll, liability insurance, inventory, merchant transaction fees, high taxes (here in Canada at least!), rent and utilities to cover each month? I am a service advisor at a dealer, so I know that you don't survive on just oil changes. You must (ethically) up-sell beyond the oil change, and I'm guessing for an oil change shop, tire rotations, air filters, cabin filters and wiper blades would be top items to up-sell, and if you have a licensed tech, maybe tire repair/balancing and brake servicing can be done. Any thoughts or opinions? Still profitable in this day and age assuming an excellent business plan in place, unique marketing angles and strong client service? Thanks in advance and sorry for the length.
