Mark - I'm not sure I buy the gas and oil explanation. I suggest you consider the following:

1. A chronic rich mixture condition, for example a high float level setting, incorrect (oversize) main jets, incorrectly set automatic choke, high fuel pump pressure, restricted air filter, etc.

2. A diet of mostly local low speed driving, and or very short driving trips.
