Light synthetic crude from the oil sands ended the session $1.90 below WTI, compared with Monday’s settle of $1 below.

Benchmark oil prices inched up on Tuesday as OPEC’s deal with associated producers last week to deepen output cuts in 2020 continued to provide a floor for prices, but U.S.-China trade tensions clouded the demand outlook.
