Many companies of other types of items that are usable in both the Marine and Automotive industry have exactly the same item inside the packaging but just sporting a different label.

It's called "Marketing" so they tell me ???

Which is fine when engine are using pressurize oil systems as the detergents will suspense the contaminates other than metal chunks for the oil filter to catch. Here Briggs is switching from the 5W30 synthetic recommendation to a 15W50 synthetic due to better upper heat range. Still should use the SAE30 non detergent for non pressurized as contaminates will settle to the bottom on the engine. Also need to continue to the 5W30 for below freezing operations as it makes starting easier.
