1.5T (L15BE)

The L15BE is the 1.5-liter turbocharged, direct-injected four-cylinder fitted to the US-market fifth-generation Honda CR-V. Honda describes it as a DOHC engine with dual variable timing control, rated at 190 hp at 5,600 rpm and 179 lb-ft of torque from 2,000 to 5,000 rpm.

It is best known for oil dilution: fuel ending up in the engine oil, mostly on cold starts and short trips. Honda ran a product update campaign for certain 2017–2018 CR-Vs sold in cold-weather states.
