Almost all modern engines are gasoline direct injected (GDI) and a lot of them are turbocharged. Honda CRV 1.5L is a good example, so are Ford Ecoboost engines. These engines are well known for fuel contamination in the oil, especially when driven for short trips where the engine doesn't get fully warmed up. Over a 10,000 mile interval you could easily end up with a quart or more of gasoline in your crankcase. Personally, I would never exceed 5,000 miles on any GDI turbo engine. Smell the oil on one sometime.
