One of the biggest changes to gasoline combustion engines in recent history is the mass adoption of direct injection technology. With direct injection, engines can run with higher compression ratios, higher boost, and higher efficiencies. The marvel has lead to widespread downsizing of engines, ditching large naturally aspirated engines in favor of smaller, turbocharged engines.

But the industry shift didn’t happen without complications; these new engines have faced three big challenges: chain wear, fuel dilution, and LSPI. In this video we’ll discuss the differences between port and direct injection, what causes the issues direct injection engines face, and how oil formulations & testing can help solve these problems.
