Hyundai Genesis Coupe 2.0T & 3.8L Engine Oil Viscosity Chart (5W-20/5W-30)

This document is an SAE engine oil viscosity chart from a Hyundai Genesis Coupe owner's/service manual showing the recommended oil viscosity grades by ambient temperature range for two gasoline engines: the 2.0 TCI (turbocharged 2.0L) and the 3.8L V6. The temperature scale runs from -30°C to 50°C (-10°F to 120°F). For the 2.0 TCI engine, SAE 5W-20, 5W-30, or 5W-40 is shown covering the entire temperature range. For the 3.8L engine, four options are shown: 20W-50, 15W-40, and 10W-30 for progressively wider (warmer-biased) temperature ranges, and 5W-20/5W-30 covering the full temperature range. A footnote (*1) applying to both engines states that for better fuel economy, SAE 5W-20 or 5W-30 oil meeting API SL or SM / ILSAC GF-3 or above is recommended, but if that oil is not available in your country, the proper oil should be selected using the viscosity chart. A reader can use this page to determine which oil viscosity grade suits their engine and local climate.
