this stuff works wonders on a 7.3 too!
there isn't much around about people using rev-x in their 7.3's, just 6.0's.
i have an '03 7.3 that has had startup issues when sitting for 3 days or more, sometimes less. it would crank for a minute before enough cylinders would start firing just enough to keep the engine turning and then it would take 5-10 minutes before it would start firing on all cylinders.
i changed the oil, added 2 bottles of rev-x, my brother drove it around for a week, i let it sit for a week after that, today it fired right up on all cylinders like it wasn't even cold. it even runs much better while warm with better throttle response.
