What happens if you add too much Sea Foam to crankcase? [SOLVED]

The recommended amount to crankcase is 1 ounce per quart in the engine…what happens if you add too much, and approximately how hazardous is it to the motor?

If you accidently add more than 1 ounce of Sea Foam Motor Treatment per quart of engine oil, we recommend driving no more than 50 miles and changing the engine oil and filter. Sea Foam is 100% petroleum based and contains no harsh chemicals or cleaners. Sea Foam will not effect engine oil viscosity. However, Sea Foam is not a replacement for engine oil.
