Piston Slap: Inject Fuel Directly Into…Oil?

Evan writes:

Sajeev,

I have a piston slap question for a friend at work. She drives an ’11 Mazda CX-7 2.3. For over a year she has had an issue with fuel in the oil. Enough that the oil level has been as much as 1″ above the full mark on the dipstick as a result (oil level was checked after service, and frequently between services). This is noticed within weeks of service/oil change.

FreedMike Just the thing for big city driving! It's easy to park, easy on gas, and there's nothing like unleashing the 700 hp beast in bumper to bumper traffic on the Dan Ryan. (Seriously, I'm finding it almost depressing to own a performance car in a place where you can use its' performance maybe 10% of the time.)
