i trailer my boats so i fill up at shell usually. i do use premium and it works just fine in my 81 350 mercruiser and my 93 305 mercruiser.

The way I understand it to be ethanol absorbs moisture from the air as it sets in the tank. In the marine environment you have a high moisture content in the air. So if you let the gas set in the tank for long periods of time you will get water in your tank and could cause serious engine problems.

Fuel prices at Turtle Creek are $4.42. Keeps going up. Times, 1 mile to the gallon. Get 89 octane fuel at a regular gas station if you are trailering. You jaw will drop when you go by the marine fuel docks.
