Starting up on the first try is a blessing.
LOL
This is a Ford F350 with 147K on the odometer, 351 (C) V8.
We parked her this Sept, ran it till quite warm, dosed the fuel with (BrandX) fuel stabilizer and disconnected the battery.
Went out, shoveled the 3 feet of snow off the hood, rehooked the battery - opened the door (more shoveling)
turned the key and - angels touched my heart - she revved right up and within 10 min, the heater was going like gang-busters.
Of course the Mobile 0-30 likely helped....
Not going to try BINGO this week tho.
