MTBE Free Fuel.
Metropolitan has banned fuels containing MTBE from the lake.
Only gasoline free of the additive MTBE is allowed. Boats containing
MTBE fuel will be turned away. The California Air Resources
Board has reported that MTBE was removed from all gasoline refined
for sale in California in Nov. 2003. Therefore, all gasoline
must be purchased in California and proof of purchase will be
required for boats with out-of-state registration. Refueling
is prohibited except in designated areas.
For those who cannot burn up the MTBE fuel in their tanks, or who are looking for a completely worry-free day on the water, rental boats are available at Diamond Valley Lake.
