Hyundai Genesis Coupe 2.0T & 3.8L Engine Oil Viscosity Chart (SAE 5W-30/5W-40)

This document is an engine oil viscosity chart (owner's-manual style) titled "Temperature Range for SAE Viscosity Numbers." It presents a temperature scale in both Celsius (-30 to 50°C) and Fahrenheit (-10 to 120°F) and shows recommended SAE oil viscosity grades for two gasoline engines. For the 2.0 TCI (turbocharged) gasoline engine, SAE 5W-30 and 5W-40 oils are shown as suitable across the full displayed temperature range. For the 3.8L gasoline engine, two bars are shown: 10W-30 for moderate-to-hot temperatures (roughly -15°C and above) and 5W-30 across the entire temperature range. A footnote for the 3.8L engine states that SAE 5W-30 meeting API SM / ILSAC GF-4 / ACEA A5 specifications is recommended for better fuel economy, and that if this oil is unavailable in the buyer's country, the proper oil should be selected using the viscosity chart. An American Petroleum Institute "Certified for Gasoline Engines" starburst seal appears at the bottom right. The engine lineup (2.0 TCI and 3.8L) corresponds to the Hyundai Genesis Coupe. The chart itself contains no explicit year, make, or model text; the year attribution (2013-2014) comes from the upload filename.
