Subject: Low Octane fuel use.......NOT

Gentlemen
I have made a career of changing BMW headgaskets for owners who insist on saving a few pennies at the fuel pump, by buying other than the highest octane available.
A side issue is the additive package for cleaning the injectors and valves. These chemicals are expensive. Some fuel companies have the truck drivers add these at time of delivery, and they are only added to the hi octane storage tanks.
