All you have to do is google HONDA 1.5 ENGINE PROBLEMS......you will find lots of information regarding fuel dilution and oil levels being 1 quart over because the fuel is unburned and gets in the crankcase. You do not find the same problems with the Honda 1.8 or Honda 2.0 engines.
Yes. Fuel dilution is part of the TGDI experience. But does it really result in premature engine failure? No evidence I’ve seen.
