I was a frequent customer of a local Hertz store. As I knew, they had an account with one of the oil change places which was nearby. Of course, do not think 3k mile changes. It was whatever the book said so as high as 10k on modern cars.
One of Hertz's internal scams would be if you were taking a one way rental, the shop where you picked up the car would provide you with a car that was due for an oil change. Then, you would drop off that car on an unsuspecting store who's store budget would then get hit for the oil change and often the negative of the car not being rented for a day while it was at the oil change place. Basically, store #1 pushing their problems off on store #2.
Now, Enterprise on the other hand, I could easily see where it would be possible that they never bothered to change oil.
When my company switched contracts from Hertz to Enterprise, boy was I disapointed. I went from Hertz's highest status in their award points system to Enterpise who had no award points at all.
I supplied my local Enterprise branch the lowest score possible, often, on their post rental surveys. I got it escalated to the point where the Area Manager for the entire region had to call me directly.
I had for him just one question: "How does it benifit me as a customer that you will not provide me with a full tank (like Hertz) when I pick up? You will penalize me if the tank is short but you will not refund me if I return with more than half."
I had for him the follwing senerio:
If I am at a 1/4 tank on a G6 and I have 150 miles to get home, how many gallons should I buy so that it is even for both of us?"
I asked to be supplied with tank capacities and average mpg for each vehicle since I would need this info so we could arrive at "fair".
To this day, my Enterprise account is tagged with, "vehicle must be delivered with a full tank."
Rant over. Boy I hate Enterprise.
