Both 2.0- and 2.5-liter versions of the naturally aspirated boxer engine from Subaru have been objects of scrutiny in recent years due to excessive oil consumption. Initially waved off as something that “Subaru engines do,” owners were told they need not worry if they added a quart of synthetic every few thousand miles. If the idea of a brand-new engine burning oil right off the lot concerns you, it should. It even led to the government stepping in.

The tipping point came in 2016, when Subaru finally admitted guilt and agreed to reimburse owners for repair costs and extend the length of their warranties. In a public statement, Subaru confessed that a defective piston ring could cause some 2011–2015 vehicles to excessively burn oil, prompting a lawsuit that alleged that Subaru knew about the problem but neglected to tell owners. Dealers had to to replace countless numbers of short blocks, a fact that lands this duo of boxer motors a number two spot on today’s list.
