NOLN launches list of direct-injection engines

It may have been quicker to list the engines that don’t have gas-direct injection fuel delivery, because GDIs are becoming more and more common with every model year.

The U.S. Department of Energy reported in 2018 that GDI engines passed half of the market share for new cars, and that’s expected to grow. Manufacturers are looking toward GDI — alone or in combination with port injection — to meet fuel economy standards. The engines have smaller displacements and are often turbocharged.

New motor oil standards have also risen alongside GDI engines to help protect components from the high-compression environments. As Solid Start’s Amber Kossak and Owen Heatwole covered in a series on GDI engines for NOLN, it’s important for operators to know how direct injection might cause the performance symptoms that customers describe. More importantly, it’s important to choose the right oil for those engines.

To help spot those vehicles as they pull up to a bay, we’ve started a list of GDI engines from major manufacturers. A link to the spreadsheet is at the bottom of this post.

The information so far has been pulled from BG of Tidewater (Va.), which listed models back to 2006, and CRC Industries, whose list is current as of 2017. Some newer models have been added too, like Jeep’s Wrangler and Cherokee, which introduced an available four-cylinder, direct-injection engine in 2018.

But the list isn’t complete. Know a GDI engine that needs to be added to the list? Let us know at
