Depends on your driving habits. If you take a lot of short trips(5500 miles for 2yr old car?) the car never gets out of open loop and will run rich. Do you make short trips?
If you drive long trips, the car gets into closed loop, (uses the O2 feed back to adjust the mixure) and the oil will reach operating temp and any fuel will be "cooked" off from the oil.
Assuming you have no mods.
I have scene modded cars with new cals, larger injectors, aux injectors, 160 degree thermostats, etc which can cause the fuel dilution, again with poor driving habits(short trips).
I have one turbo car with +20% injectors, 20 PSI boost calibration. I can watch my EGT(Exhaust gas temp) go from 1400 to 1475 at part throttle and at WOT the temp drops back down to 1400. The cal is slightly rich at WOT to prevent detonation. I can probably raise the boost a bit and still be on the safe side.
