I am going to be at texoma in a few weeks and want to know if there is a place to get 89 octane non-ethanol in the lighthouse-highport area?

no you have to go across the river to the Durant area or the north end of the lake to get no ethanol

Thanks for reply bassplay. Where abouts in durant or on north end?

Enderby Gas in Whitesboro has E free gas. Closest thing I know of unless you go up into OK. There are several places across the border that sell it. pure-gas.org

just west of the 70 bridge at texoma tackle, they have all octanes in non ethanol.
you can launch at the east end of bridge after you buy gas so it's convenient. take first road at east end of bridge and just follow it.

You could drive to Dallas and back quicker than you can go from lighthouse to catfish bay by road. I think most of the marinas have ethanol free fuel.

How do you know if the gas is truly ethanol free ?

You could use a test kit

Highport was one of the last ethonal free stations on the lake. They stopped carrying it about two months ago. I don't know of any on the lake that are still selling it.
