When it comes to choosing between changing the oil for individuals driving their personal SUVs and for fleet delivery vehicle managers one has to take into account the time, not only the total amount of money charged per vehicle. It may be enticing to change the oil for V-8 SUV owners at $45.00 a pop, rather than deal with the cutthroat competition of bidding on fleet oil change services, but you have to keep in mind something; "The Money Is In the Time and Process, Not the Unit Charge Rate," so, let's talk fleet services and management.
You see, soon ago, I was reminded of the importance of production in the services business, when I was asked by a start-up entrepreneur of on-site auto maintenance. He asked point blank; "Exactly how many oil changes could be completed by a decent crew (I am assuming 2 visitors to a crew/truck) in a 8 hour day using your trucks and methods?"
Okay, here's my experience; with full production - Six Sigma style - vehicles in a row (fleets) the answer is 100s with a team of three. Personal cars, various different, you will need very competent auto mechanics with experience 5-6 hourly with 2 people maximum. Needless to say, there's more to the story, in fact his next question was even blunter and I must say close to target too; "Do the trucks you employ focus on one vehicle at the same time or multiple at the same time?"
When doing fleets you employ an assembly line methodology, so first, you start the motors on five vehicles, nevertheless, you pop the hoods on 15 in the row. After 8-minutes, you turn off the very first five, start the second five, drain the very first five drain plugs, you get the idea. Or, you employ evacuation systems. It's an activity, the money is in the "time" not the work or cost per unit. Travel time is job time in addition gps tracker for car, including chasing parts, filters - especially when you are paying automotive technicians to fetch oil filters, fuel filters, and such.
Indeed, I've always instructed our crews on the necessity to honor the thought of JIT - just with time inventory, that's to state have the supplier, NAPA Auto Parts for example, deliver the filters needed seriously to the work site, why pay to stock the filters, inventory them, transport them, when these auto part companies deliver and will do anything to earn your company? If you are likely to run an auto business whether you are working with private owners of SUVs or those in control of large fleets of vehicles, you then need to perform it with production in mind. Please think over all this and think on it.
