Diesel before Keys
I was just there three days ago.
First off diesel in Key West is pretty expensive. I try to fill up in Homestead and drive all the way down and back to avoid fueling down there.
1. Just before US1 turns into a four lane divided highway that leaves the mainland the towns of Florida City and Homestead have cheaper fuel. The problem with a lot of stations you can't get a big rig amongst the hectic traffic. At the end of the Florida Turnpike go west one block and travel south on Hiway 997 (Krome Ave) and drive south paralleling US-1. There were several large stations with ability to fit big rigs. The diesel was about $3.85. I saw Hess, RaceTrak and Sunoco.
2. I was surprised there were three stations at the North end of Key Largo that had diesel for about the same price. Again Hess was one of them. The three I saw were immediately after US-1 finishes the causeway into Key Largo and then again just south of John Pennekamp SP.
South of Key Largo the price goes up.
Take bug spray, the "no-see-ums" we're voracious at sunset.
