Great stash! The Redline SI1 is great stuff, ain't it? I had a 1990 Nissan pick up some years ago and decided to change the fuel filter. When I poured out the gas in the old filter, it looked like coffee with cream - light brown. I put a new filter on, added a bottle of SI1. I used SI1 about every 5,000 miles and when I changed the fuel filter the next time, about 30,000 miles later, I poured the gas out and it was just like it came from the pump. Stuff really works. Now use it in all my vehicles.
