RECl"ENDE0 SAE VISCOSITY GRADE ENGINE OILS As shown in the chart, if you have the 3800 engine, SAE 1OW-30 is best for your vehicle. However, you can use SAE 5W-30 if it's going to be colder than 60°F (16OC) before your next oil change. When it's very cold, you should use SAE 5W-30. These numbers on an oil container show its viscosity, or thickness. Do not use other viscosity oils, such as SAE 2OW-50. FOR BEST FUEL AND COLD STARTING, SELECT THE LOWEST SAE VISCOSITY Gmmw= J L FOR THE EXPECTED TEMPERATURE RANGE. HOT WEATHER / LOOK FOR THIS SYMBOL SAL SW-30 \ . .
