My 13' SHO calls for 89 octane. I ALSO run ethanol free 87 octane in my older Mercury motors. Haven't had ANY fuel related issues in motors/fuel lines/bulbs etc for over 2 years.NO PHASE SEPERATION/MOISTURE collecting problems!!(knock on wood)!!! It costs a little more per gallon, but, its WORTH .25-.40 cents a gallon more, to NOT have ethanol issues. I run 89 octane non ethanol & Yamaha Ring free & Stabil 360 in my SHO 250 Yamaha & use 87 octane ethanol free with Mercury ring/carbon additive & Stabil 360 in my Mercs. I ALSO install & maintain fuel/water separator filters on ALL my boats.
Lookup pure-gas.org app on line. All U.S individual states & Canadian Locations. Find Tx at top of listed states & click. It gives all locations in each state that sells ethanol free gas, which octane ratings, address of locations & phone# of those locations.
I do know WalMart Murphy station in Weatherford sells 87 ethanol free fuel for the closest one to Stephenville or I think there may be a location in Dublin Tx west of Stephenville. Good luck & avoid ethanol problems period, by doing this.
PS: I have also started running it in my Chevy pickup that I tow with. Better fuel mileage empty & towing.
