We always recommend sticking with the motor oil viscosity the manufacturer recommends and, in your situation, you can use Pennzoil Ultra Euro 5w-40 motor oil. It is a similar formulation in the specific viscosity recommended for your vehicle. Because we fully formulate each motor oil we create, you can use the Euro formulation in your American vehicle because it meets all US engine oil requirements.
The newer 0w-40 Pennzoil Ultra motor oil was developed for the current model 8- and 10-cylinder model SRT engines.
