Why do Boats seem to have more issues with E10 fuel than cars?
Cars also have some issues with E10 fuel, however they are somewhat more tolerant due to the typical usage paterns of cars and certain structural diffrences in their fuel systems. • Modern Automotive fuel systems are closed (non-vented). Once fuel is pumped into the tank there is very little circulation of outside air. This helps to protect the fuel from moisture in the air. • Boats are operated and often stored in a very wet environment further increasing the risk of water directly entering the fuel system. • Boats have vented fuel systems which allow moisture from the air to circulate into the fuel tank as the fuel is drawn out of the tank. • Automotive fuel tanks are typically much smaller and are refilled more frequently. Typically automotive fuel tanks range from 10-40 gallons and are refilled every 1-2 weeks. By contrast boat fuel tanks are typically 30-90+ gallons and are typically refilled once per month durring the boating season and often sit for months at a time. • Some boat
