You found a 5 gallon jug? Where?
The Euros are different based on the viscosity. 0W40 is full-SAPS ACEA A3/B4 rated and good for long drains, 5W30 is low-SAPS ACEA C3 rated and not a good choice for extended drains in US gasoline engines. In a gas engine, you are probably better off sticking with plain Pennz Platinum in the correct viscosity for your vehicle.
