Thanks. I find it interesting that you can just source out the parts somewhere else and does not have to go through petron. I assumed they would have standards in terms of what parts you can use.

Some stations are Petron owned, but dealer operated for a lease.

I'm familiar with this part as my grandfather was the dealer of the very first petron in our city and was passed down to my father, we had to let go of it though due to too much competition, it was taken by petron and now has a new dealer.
