Went ahead and filled up last night with 87. Pretty much everything around me has "up to 10%" ethanol. It was $102.31 when it clicked off at 3.79 a gallon. I think I was wrong about needing two tanks for our trip. It's only around 95 miles to the state park, so might make it on one tank if we don't run around too much. Leaving in a few hours and I'll be off the grid till Sunday night. Later
